Batrider
* Nyx can walk into Firefly with 
Spiked Carapace and stun Batrider if he has no Spell Immunity, even if Batrider is focusing on other enemy hero.
Medusa
* 
Vendetta burns a significant amount of mana on hit, and the damage from the ability drains Medusa's mana pool even further.
* Due to the passive nature of Mystic Snake and Split Shot, it can possibly proc Nyx's Spiked Carapace if he's within range of Medusa's abilities and isn't invisible.
* Medusa lacks single target damage, making Nyx with 
Aghanim's Scepter extremely hard to deal with if Medusa is the team's main damage source.
Additional:
* With her passive 
Split Shot, Medusa can be easily interrupted by Spiked Carapace during combat, especially during her precious 
Stone Gaze.
* Mana Burn quickly destroys 
Mana Shield, especially if Medusa only increases her mana pool by bolstering intelligence (which has the added bonus of increasing Mana Burn's damage).
* Uncontrollable damage from 
Mystic Snake and Split Shot can trigger Spiked Carapace.
* 
Medusa lacks single target damage, making a Burrowed Nyx Assassin hard to kill.
Batrider
* 
Dark Pact can dispel Flaming Lasso if is used in anticipation, but a Blink initiation from fog can catch the Slark off guard.
* Slark can also take off any Sticky Napalm stacks with Dark Pact in lane.
Additional:
* Shadow Dance's passive can inform Slark when he's under enemy vision, meaning it'll be very hard to catch Slark off-guard with 
Flaming Lasso.
* Flaming Lasso is dispelled by Dark Pact. Its casting can be prevented with 
Shadow Dance or 
Depth Shroud (it requires 
Aghanim's Shard).
Medusa
* Medusa is especially vulnerable to 
Essence Shift, as both strength and intelligence contribute to her effective HP, while agility contributes to her damage.
* Dark Pact when timed right can be used to dispel Stone Gaze right after it petrifies Slark, allowing him to keep attacking Medusa throughout the duration.
Additional:
* Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regenerating before coming back to finish her off.
* Essence Shift particularly removes 1 intelligence point per hit, thus lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.
Batrider
* QW-Invoker perfectly resists Batrider in his attacks, since Batrider has a small mana reserve and depends very much on him - 
E.M.P. perfectly allows Invoker to deprive her, and he also has the abilities of 
Tornado and 
Cold Snap, which can help him fend off his attack, and possibly even kill along with his team

Medusa
* E.M.P. allows Invoker to burn Medusa's mana to weaken Mana Shield.
* Medusa's lack of mobility makes her easy to kite with Invoker's spells.
Additional:
* E.M.P. is a large mana burn nuke which can hit Medusa's Mana shield with enough damage to lose even more mana.
* 
Deafening Blast disarms Medusa's ability to deal pseudo-AOE damage during teamfights.
* Cold Snap allows the opposing team to repeatedly stun Medusa in short succession, preventing her from successfully casting her ultimate due to its long cast time.
Batrider
* Doppelganger dispels 
Sticky Napalm and 
Flamebreak.
* There are usually way too many illusions for Batrider to lasso the real Phantom Lancer, since the illusions' hitboxes also body block the real Phantom Lancer.
Medusa
* Phantom Lancer with 
Diffusal Blade will very quickly burn Medusa's mana, making Mana Shield significantly less effective.
* 
Doppelganger's 1 second invulnerability can be used to dodge Medusa's petrification from Stone Gaze, as well as Mystic Snake.
* Phantom Lancer's illusions outnumber Medusa's targets from Split Shot, likely shielding his team in the process.
Batrider
* 
Kraken Shell can dispel Flaming Lasso.
* If Batrider drags Tidehunter back towards his team, it can be setup for a well placed 
Ravage.
Additional:
* Kraken Shell is very useful against Sticky Napalm and Flamebreak, easily dispelling them regularly.
* Tidehunter is probably the worst hero to target with Flaming Lasso, as Kraken Shell will remove it and Tidehunter often survives long enough to cast Ravage in the middle of Batrider's team. At the same time, if Batrider initiates on his teammate, Tidehunter will have the perfect opportunity to counter-initiate.
Medusa
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: 
Tidehunter, 
Bristleback, 
Slardar.
Batrider
* Sticky Napalm, Flaming Lasso, and Flamebreak can all be instantly dispelled by Aphotic Shield.
* 
Firefly will continuously heal Abaddon under Borrowed Time.
Additional:
* 
Aphotic Shield and 
Borrowed Time can both dispel Flaming Lasso.
Batrider
* 
False Promise dispels Flaming Lasso.
* 
Fortune's End can root Batrider after he uses Flaming Lasso. It can also dispel Sticky Napalm and Flamebreak.
* 
Fate's Edict when used on a Lasso'd target will leave them immune to magical damage, making it difficult to burst them quickly before the Lasso ends.
Batrider
* 
Nether Swap breaks Flaming Lasso when used on ally and can break if used on Batrider.
* Vengeful Spirit can disable Batrider's 
Blink Dagger before a fight with 
Wave of Terror.
Additional:
* With her Nether Swap, Vengeful Spirit can save the life of an ally who gets caught with Flaming Lasso. Nether Swap also makes it highly dangerous for Batrider to attempt a lasso, as it can lead to his own demise far behind enemy lines.
* Wave of Terror's flying vision allows Vengeful Spirit to spot Batrider trying to close in on his target with Firefly.
Medusa
* Webbed areas can be used to hit and run, covering distance hastily weakening her on the way and initiating ganks.
* Even though Medusa can hunt down Spiderlings easily when given enough range, 
Silken Bola will cause her attacks to miss and get her swarmed in no time.
* Medusa usually does not build a Black King Bar to benefit from Mana Shield fully while Broodmother can fit a Diffusal Blade to burn away all of Medusa's mana.
Additional:
* 
Spin Web will allow Broodmother to pick her own fights and sometimes slip away to ambush Medusa.
* Though Medusa's Split Shot and Mystic Snake can help Medusa deal with Broodmother's spiderlings, Broodmother will create too much of them for her to handle, allowing her to outnumber Medusa's targets from Split Shot and shield her team in process.
Medusa
* Fiend's Grip provides mana drain, which can heavily damage Mana Shield and prevent Medusa from using Stone Gaze.
* Even if she does use Stone Gaze, Nightmare can buy enough time to protect allies and reset the fight.
Additional:
* 
Fiend's Grip leaves Medusa defenseless, since not only does it deal damage, it also drains mana.
Batrider
* 
X Marks the Spot breaks Flaming Lasso when used on ally and can break if used on Batrider.
Batrider
* 
Time Lapse with Aghanim's Scepter dispels Flaming Lasso when used on allied hero.
* 
Linken's Sphere is core item for a Weaver making him a hard target for Lasso during entire game.
Batrider
* Batrider has poor survivablilty, relying on his mobility from Firefly to survive. Stunning him with Ice Path of Liquid Frost can easily spell his doom.
* Batrider tends to cast Flaming Lasso on the squishest or the tankiest hero. Which Jakiro is not squishy, nor his generally the tank of the team, Due to this, Jakiro can usually save allies with Ice Path and Liquid Frost, while also potentially removing an entire hero from play for a short period of time.
* Even if Batrider does cast Flaming Lasso on Jakiro, Batrider will generally drag Jakiro into a great setup for Ice Path and Macropyre.
Medusa
* With 
Static Link, Razor can effectively make Medusa useless in teamfights by reducing her main damage output. It can, however, be blocked by a Linken's Sphere.
* 
Plasma Field allows Razor to get on top of Medusa, slowing her already slow movement speed to a mere crawl.
* 
Eye of the Storm capitilizes on Medusa's low armor and causes her to be very vulnerable, even through Mana Shield.
Medusa
* Silencer burns easily through her effective HP from Mana Shield, by taking away her intelligence.
* 
Arcane Curse punishes her repeatedly casting Mystic Snake to keep her mana pool high. He can force her to use 
Manta Style before he has cast 
Global Silence and Medusa usually does not want to build 
Black King Bar.
Medusa
* With 
Smoke Screen, Riki will silence and catch Medusa in a surprise with high miss chance flushing her from positions easily in team fights.
* He can deal a huge amount of damage through 
Cloak and Dagger, even through Mana Shield.
Batrider
* Queen of Pain can be an effective tool against Batrider in the game and on the line. She has long-range abilities such as 
Scream of Pain or 
Sonic Wave and a long-range type of attack, which is why she can keep Batrider at a distance all the time, and prevent him from attacking with Flaming Lasso or Firefly. Queen of Pain has an effective high-deceleration ability against Batrider - 
Shadow Strike, which is why he cannot quickly set fire to all enemies under Firefly and fly between all Queen of Pain allies. In addition, Queen of Pain has a wonderful escape in stock - 
Blink, which can save her at any moment in which batrider decides to attack

Medusa
* Anti-Mage easily destroys Mana Shield with Mana Break, especially once he has Manta Style.
* Anti-Mage effectively avoids Stone Gaze with Blink, and can reinitiate after its duration is over.
Additional:
* 
Mana Break burns Medusa's mana easily, especially when coupled with a Manta Style.
* Can easily initiate on Medusa with 
Blink, burning her mana or forcing her to use Stone Gaze.
* 
Mana Void is effective against Medusa's big mana pool and mana usage, presenting a huge hazard to Medusa's allies around her since her Mana Shield still gives her some protection if she has mana.
Medusa
* 
Burning Spear's damage over time can rapidly burn Medusa's mana and health alike.
* 
Inner Fire can slow and disarm Medusa and also allow Huskar to follow up with Life Break.
Batrider
* 
Plague Wards are very hard for Batrider to play against as they provide a lot of vision as well as disable Blink Dagger for a long duration.
Medusa
* Heroes who take a long time to become strong are in for a rough mid game, such as 
Outworld Destroyer, 
Magnus, Medusa, and 
Anti-Mage.
Batrider
* 
Death Prophet is a terrible Flaming Lasso target if 
Exorcism has already been used, since it can still damage Batrider and his teammates, but if Batrider manages to Lasso her before that, it can lead to Death Prophet being quickly burst down.
Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: 
Riki, 
Naga Siren, 
Terrorblade, 
Juggernaut, 
Spectre, 
Slark.
Medusa
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as Medusa, 
Drow Ranger...
Medusa
* Heroes with extremely slow movement speed will cripple against Solar Bind: Medusa, 
Viper
Additional:
* 
Will-O-Wisp will keep Medusa busy after she got hit by 
Blinding Light.
Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark.
Medusa
* Medusa lacks mobility or escape mechanisms. 
Earth Spike and 
Hex can neutralize her strong damage potential and allow for 
Lion's team to focus her down.
* 
Mana Drain is a perfect ability to weaken Medusa's durability as it can quickly drain her Mana Shield, making her far less tanky. Mana Drain can also be used to restore mana of Lion's allies, which can nullify the mana steal from Mystic Snake.
* Mana Drain, along with Hex, destroy illusions instantly, which may be extremely helpfull and efficient against core builders of Manta Style, like Medusa herself.
Batrider
* Batrider often hides in the trees to initiate on a target. As such, he has a slight edge against heroes that have no scouting tools and cannot see him coming, such as Lion or 
Sven.
Medusa
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Additional:
* Medusa is a fairly immobile hero that deals damage around her with Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
Batrider
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, 
Disruptor, 
Pudge, 
Vengeful Spirit.
Batrider
* Sticky Napalm slows Chen and his creeps and Flamebreak and Firefly can deal heavy damage to them.
* Flaming Lasso can pull Chen away from his creeps toward Batrider's team, often to certain death.
Additional:
* Sticky Napalm slows Chen and amplifies Batrider's damage.
* Flamebreak and Firefly can deal heavy damage to Chen and his creeps.
* Flaming Lasso pulls Chen away from his creeps, often to certain death.
Medusa
* Medusa's Split Shot can easily kill Chen's creeps.
* Mystic Snake can quickly kill Chen's creeps and deal intense damage for every killed creep while also draining their mana with each bounce. Aghanim's Scepter upgraded Mystic Snake can also disable both, Chen and his creeps upon impact.
* Mana Shield will make it impossible for Chen to burst down Medusa.
* Stone Gaze can disable Chen from using 
Hand of God to save himself or his allies.
Batrider
* Flaming Lasso is the perfect tool to isolate a single Meepo and focus him.
Medusa
* Poof won't damage Medusa and she can use Stone Gaze to disable all of Meepo's clones.
* Mystic Snake will easily become the bane of Meepo early game.
Batrider
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: 
Axe, 
Beastmaster, 
Enigma, Magnus, Pudge, Batrider, 
Bane, 
Winter Wyvern
Medusa
* Split Shot will keep attacking Pangolier even when he is rolling around.
* Stone Gaze stuns Pangolier during Rolling Thunder, or forces him to roll away.
Batrider
* Batrider's Flaming Lasso can be used to cancel Io's attempts to escape with 
Relocate and drag him away from his 
Tethered target. And since Io doesn't like buying Linken's Sphere, he will be always vulnerable to Batrider's initiations.
* Io's tendency to stick close to it's Tethered target can make Io and it's target vulnerable to Batrider's harrasing.
* Aghanim's Scepter upgraded Flaming Lasso allows Batrider to catch and drag two heroes at once, not just one. Which can potentially turn Io's Tether against him.

Medusa
* Heroes that are hard to gank: Axe, Death Prophet, 
Phantom Lancer, Slark, 
Centaur Warrunner, Bristleback, Medusa, 
Mars.
Batrider
* Phantom Assassin does not deal with early aggression very easily (especially when magical damage). A competent Batrider can make life very difficult with Sticky Napalm followed by any other spell.
Medusa
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, 
Doom, Bane, Beastmaster, Pudge, Medusa, 
Warlock.
Batrider
* Heroes with disables that go through spell immunity can end Bloodseeker before he has the chance to do anything: Batrider, Beastmaster
Medusa
* Mana Shield makes it very difficult for Bloodseeker to gain his Thirst bonuses.
* Rupture rarely kills Medusa through Mana Shield.
Batrider
* Batrider often hides in the trees to initiate on a target. As such, he has a slight edge against heroes that have no scouting tools and cannot see him coming, such as Lion or Sven.
Medusa
* Stone Gaze allows Medusa to easily kite and kill Sven.
* Mana Shield negates much of Sven's burst damage.
Additional:
* Mana Shield makes it very hard for Sven to burst her within Storm Hammer's stun duration.
* Stone Gaze makes it very difficult for Sven to fight Medusa at any stage of the game.
* Mystic Snake can slow Sven down enough for allies to capitalize on his commitment in a fight.
Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark.
Batrider
* Many stacks of Sticky Napalm, combined with Flamebreak and Firefly, allows Batrider to destroy illusions from 
Mirror Image.
* If Batrider can manage to destroy all illusions from Naga Siren, he will be able to use Flaming Lasso on the real one, and will be able to drag her toward his team, potentially preventing Naga Siren from escaping with 
Song of the Siren.

Medusa
* Medusa's Split Shot and Mystic Snake combined with 
Mjollnir, a common item for Medusa, will whittle down all of Naga Siren's illusions, including Naga Siren herself.
* Medusa's Stone Gaze can disable Naga Siren even for the duration of Song of the Siren and even if Naga Siren is spell immune, discouraging Naga Siren from even trying to use Song of the Siren to save herself or counter-initiate against Medusa.

Batrider
* Any long duration disables that can pierce through both, Pierce The Veil and Black King Bar are devastating against Muerta: Enigma's 
Black Hole, 
Dawnbreaker's 
Solar Guardian, Axe's 
Berserker's Call, Naga Siren's Aghanim's Scepter upgraded 
Ensnare and 
Reel In from Aghanim's Scepter,

Venomancer, 
Elder Titan, 
Faceless Void, 
Rubick,

Meat Hook and Vengeful Spirit with Nether Swap.
Medusa
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.
Batrider
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's Aghanim's Scepter upgraded

Batrider
* As long as Batrider is under the effect of Firefly, he can safely fly over 
Proximity Mines (He does not receive vision over the mines).
Batrider
* Firefly destroys trees and can turn 
Tree Dance into a free four second stun.
Additional:
* Firefly allows Batrider to gain vision of Monkey King while he is on an tree, as well as destroying any nearby trees, denying Monkey King spots to jump to, or causing him to fall.
* Sticky Napalm's turn rate slow makes it significantly more difficult for Monkey King to jump from tree to tree and gain Jingu Mastery stacks. It also reveals Monkey King while he is on a tree.
* Flamebreak and Flaming Lasso enable Batrider to remove Monkey King out of Wukong's Command.
Medusa
* Doom does not disable Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.
Medusa
* Enchantress often has a small army of neutral creeps, allowing Medusa to hit her with a later bounce of her Mystic Snake.
Batrider
* Batrider's DoT damage quickly removes Templar Assassin's 
Refraction and can damage her during 
Meld.
Additional:
* Batrider's abilities are designed to deal damage over time, burning through Templar Assassin's layers extremely quickly. Flamebreak applies 7 instances of damage, burning through the entirety of Refraction, and Firefly applies damage on the place, forcing her to either get out of Meld and be attacked or stay in place or be incinerated.
* Flaming Lasso pierces Black King Bar and rendering Templar Assassin helpless unless there are allies helping her.
Batrider
* Firefly can be used to clear Nature's Prophet's Treants and allows Batrider destroy Sprout's trees.
* Flaming Lasso prevents Nature's Prophet from escaping using Teleportation.
Medusa
* Her Mana Shield is too tough for Lycan to break.
* Mystic Snake can hit for a massive damage once it spread between his summons.
Additional:
* Can be easily petrified despite his speed.
* Summoned wolves will be targeted by Split Shot or Mystic Snake
Medusa
* Mana Shield can tank most of the damage from Reaper's Scythe; with sufficient mana, the kill threshold drops significantly.
* Necrophos has a movement speed equal to Medusa, and is easy to chase down with a slowing item in Medusa's inventory.
Medusa
* Should Luna choose to buy Manta Style, Medusa will be able to kill illusions from them with Split Shot and Mjollnir, which is a common item on Medusa.
* Mystic Snake allows Medusa to easily harass Luna and steal mana from her, preventing Luna from retaliating with 
Lucent Beam.
* Medusa can survive Eclipse thanks to Mana Shield, which can cause Luna to struggle greatly in bursting down Medusa and force her to buy Diffusal Blade and it's upgrade 
Disperser.
* Even with Black King Bar, Medusa's Stone Gaze will still be able to disable Luna, which could even discourage her from counter-initiating with Eclipse.
* For the same reasons, Medusa makes a very powerful ally for Luna when they are in the same team.

* Mystic Snake allows Medusa to easily harass Luna and steal mana from her, preventing Luna from retaliating with Lucent Beam.
* Medusa can survive Eclipse thanks to Mana Shield, and since Luna is not a hero that often goes for Diffusal Blade, she will struggle greatly in bursting down Medusa.
* Even with Black King Bar, Medusa's Stone Gaze will still be able to disable Luna, which could even discourage her from counter-initiating with Eclipse.
* For the same reasons, Medusa makes a very powerful ally for Luna when they are in the same team.
Medusa
* If Medusa activates Stone Gaze before Spirit Breaker reaches her with Charge of Darkness, the charge will inevitably fail.
* Medusa has three ways to counter Spirit Breaker's Charge of Darkness: Stone Gaze can disable Spirit Breaker's Charge of Darkness if he faces Medusa directly. Aghanim's Scepter upgraded Mystic Snake can disable Spirit Breaker and cancel his Charge of Darkness if it hits him. And 
Cold Blooded provided by Aghanim's Shard that can cast a single-targeted Mystic Snake at Spirit Breaker if he uses Charge of Darkness on her.
* Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation. And to make things worse, Spirit Breaker is not a common Diffusal Blade nor Disperser wielder to counter this problem at all.
* Overall, any attempt for Spirit Breaker to gank and kill Medusa will hurt him more than the other way around.
Batrider
* Firefly and combinated with Blink Dagger can easy avoided from 
Focus Fire.
Medusa
* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* Medusa can also kill Eidolons with her Mystic Snake that can also greatly damage Enigma and drain some of his mana.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating and landing an effective Black Hole exceedingly difficult, because Stone Gaze can cancel Enigma's Black Hole even through spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.

Medusa
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
Medusa
* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces 
Rage, wasting its cooldown and making Lifestealer unable to fight.
Batrider
* Batrider has huge damage from his Sticky Napalm and hand strikes on the target, with this effect. And Ember Spirit not only has a small reserve of health, but also has a melee type of attack. If these two collide on the center line, then Ember Spirit will have to finish off several creeps from afar with a Sleight of Fist, otherwise he will lose a lot of health from long-range Batrider attacks under Sticky Napalm, and possibly even kill, because Ember Spirit does not have the ability to interrupt Batraider with his damage if he decides to attack
* Ember Spirit is a very tasty target for Flaming Lasso, because it has a small reserve of health, and all the power lies in the abilities that Flaming Lasso forbids using, this can help the Batraider team quickly deal with the unpleasant "jumping" Ember Spirit in a fight if he gets into Flaming Lasso

Medusa
* Visage's familiars are easy targets to Split Shot.
* Mana Shield will resist Soul Assumption instances without effort.
Batrider
* Firefly will cut trees with ease, cleaning-up an area that's been enchanted with 
Eyes In The Forest, and potentially revealing a Treant under the effects of 
Nature's Guise.
* Batrider's DoT spells are also good versus 
Living Armor.
Medusa
* Heroes with Linken's Sphere as core item: 
Weaver, 
Morphling, Medusa.
Medusa
* 
Bulwark can make each of Medusa's attacks target him instead, reducing Medusa's contribution on team fights.
* 
Spear of Mars stuns Medusa and also pushes her away from teamfights, taking advantage of Medusa's low mobility.
* Arena Of Blood blocks Medusa's attacks from outside the arena.
Batrider
* Sticky Napalm slows turn rate, making it difficult for Mars to face frontwards, where Spear of Mars and Bulwark are effective. In combination with Firefly, which deals magic damage, Batrider can make quick work of Mars.
* Flaming Lasso disables Mars while enemies re-position themselves behind Mars to avoid Bulwark.
Medusa
* Medusa's Stone Gaze forces Mars to choose between getting petrified, or turning his vulnerable back on Medusa.
Batrider
* For the same reason, he has to be slightly more cunning when playing against heroes that can scout the treeline, such as Ancient Apparition and his 
Ice Vortex and 
Shadow Demon and his 
Shadow Poison.
Batrider
* Heroes with stronger lane presence that can threaten to kill him: Batrider, Juggernaut, 
Ursa, Monkey King, Razor.
Medusa
* Axe can take advantage of Medusa's awfully low HP to insta-kill her with 
Culling Blade, making it extremely difficult for her to farm for items to compensate for the lack of strength during early and mid-game while Axe is continuously harassing around.
Batrider
* Heroes who can stop Axe from getting close will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, 
Arc Warden, Winter Wyvern, 
Clockwerk
Medusa
* Mana Shield reduces the effectiveness of Counter Helix.
* Stone Gaze makes it very difficult for Axe to initiate on Medusa and her allies.
Batrider
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider.
Batrider
* Shadow Demon, Outworld Destroyer and 
Tusk can all save a Lasso'd teammate with their defensive spells.
Batrider
* Sticky Napalm makes it difficult for Tusk to hold his own on lane.
* An ill-timed and ill-positioned 
Snowball will give Batrider a free counter-initiation with Flaming Lasso if Batrider is far enough to avoid the stun from the Snowball.
Additional:

Batrider
* Shadow Demon, Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.
Batrider
* Batrider prevents sharp and brazen attacks of the opponent. First he catches him in a Flaming Lasso, and then causes huge damage, in some cases even incompatible with life.

Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark.
Batrider
* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, Batrider, Earthshaker, Elder Titan, Faceless Void, Invoker, 
Legion Commander, Mars, 
Primal Beast, Riki, Shadow Shaman, 
Silencer, Vengeful Spirit, 
Void Spirit.
Medusa
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, Bristleback, Slardar.
Batrider
* Batrider's turn rate slow from Sticky Napalm makes it harder for Bristleback to keep his back towards the enemy.
Batrider
* Zeus is good against heroes that juke in trees or up cliffs, like Batrider, Monkey King, Spectre, and 
Tinker, by providing vision in any area with Lightning Bolt, or guaranteeing vision on enemies with Thundergod's Wrath.
Medusa
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.
Medusa
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, Bristleback, Slardar.
Medusa
* Medusa cares less than other heroes about armor reduction, since Mana Shield blocks 70% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
Batrider
* Shadow Demon, Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.
Batrider
* For the same reason, he has to be slightly more cunning when playing against heroes that can scout the treeline, such as Ancient Apparition and his Ice Vortex and Shadow Demon and his Shadow Poison.
Batrider
* 
Press the Attack dispels Flaming Lasso.
* Batrider is unlikely to win a 
Duel in any stage of the game.
Medusa
* Mana Shield makes Medusa very hard to take down in Duels.
* Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.
Medusa
* He can use either his own or his double's 
Flux to bypass the spellblock from Linken's Sphere, using the leftover Flux + 
Spark Wraith to slow Medusa's already low move speed to a crawl.
* Arc Warden has a farming advantage with double 
Hand of Midas, and can generally bully Medusa with other items that benefit from duplication.
Batrider
* Batrider can harass Arc Warden more easily with Sticky Napalm thanks to it's low cooldown and mana cost and because of Arc Warden's lower durability and mobility.
* Batrider can use Flamebreak to push Arc Warden and 
Tempest Double out of the 
Magnetic Field.
* With Firefly combined with Blink Dagger, Batrider can move faster while dealing damage to both Arc Warden and Tempest Double.
* Flaming Lasso allows Batrider to separate Arc Warden from both Magnetic Field and Tempest Double and pull him towards Batrider's team. Aghanim's Scepter upgraded Flaming Lasso also allows Batrider to disable both, real Arc Warden and his Tempest Double and pull them towards Batrider's team. And since Arc Warden is not used to buy Linken's Sphere, this can be a great problem to him.
* Since Arc Warden is not used to buy Black King Bar very ofthen In most of the stages of the game, he will be vulnerable to Batrider's magical damage-over-time output in most of the stages of the game.
* However, Batrider needs to approach Arc Warden carefully as Arc Warden can scout Batrider's location with Spark Wraith. Also, Arc Warden tends to buy 
Gleipnir which combined with Flux's damage over time can be used to prevent Batrider from even using Blink Dagger.

Enrage with 
Aghanim's Scepter can dispel Flaming Lasso.
Medusa
* Ursa's status resistance from
Enrage reduces duration of Medusa's Stone Gaze.
Fury Swipes easily against her Mana Shield in a prolonged team match.
* Ursa can stack damage with
Additional:
* Medusa's tankiness doesn't help her very much against Fury Swipes in long teamfights.
* With no escape mechanism and a slow movement speed, getting jumped on by Ursa usually spells a quick end for Medusa in the early game.
