* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.

* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus

* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, Nyx Assassin.

* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.

* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.

Additional:
* Battery Assault prevents Jakiro from casting spells as all his spells have very long cast times.
* Jakiro is also an easy target for Clockwerk's Hookshot + Power Cogs combo, as he has little mobility and no escape without items.
* Alternatively, if the enemy Clockwerk traps one of his own allies or Jakiro's allies in the cogs, it gives Jakiro an ideal setup to punish Clockwerk and his ally or to save Jakiro's ally, respectively.

* High priority targets like Queen of Pain, Drow Ranger, Ember Spirit can't get caught out from Lion's long range disables, making it harder to them fulfill their roles, and making it easy to target them.

* Heroes with high burst damage: Lina, Lion, Luna, Nyx Assassin, Queen of Pain.

* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage

* Backline supports (Lion,Crystal Maiden) can keep Puck pinned long enough for a kill.

* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.

* Heroes with mobility spells (such as Queen of Pain's Blink and Clockwerk with Hookshot) can easily avoid Lil' Shredder and Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.

* Heroes with channeling spells, for Chen has no disables on his own, hates buying disabling items and his creeps are often not fast enough to cancel them: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.

* Sniper lacks any protection against Lion's disables early in the game.
* Lion's Earth Spike and Finger of Death may roughly hit Sniper at the latter increased attack range, making it possible to gank and to disable him from afar in clashes.
* Finger of Death is incredibly dangerous for Sniper as it may shred him away from fights, or in the worst scenario, cause his death.

* Clockwerk is also the least optimal target for Sniper to attack in a teamfight, although more experienced players will rarely make this mistake.
* With no mobility or disable skills, getting trapped in Power Cogs is a death sentence for Sniper.

* Drow Ranger has a very low health pool, allowing Lion to burst her down.
* Lack of any innate escape mechanism makes her an easy target for Lion's disables.
* Early on she can't deal as much damage to be life threatning. Her Gust is her best weapon against Lion.

* Getting trapped in Power Cogs usually means the end for Drow Ranger.
Additional:
* Hookshot lets Clockwerk close the gap to Drow Ranger, disabling her Marksmanship bonus.
* Power Cogs and Battery Assault keep Drow Ranger from escaping.
* Power Cogs and Battery Assault also keep Drow Ranger close, nullifying Marksmanship.

* With a lot of disables with good range, he might cancel your Echo Stomp.
* Mana Drain can be used to drain Elder Titan's already low mana pool.

* Battery Assault's continuous mini-stun makes it hard for Elder Titan to cast his spells due to his poor cast animation.
* Elder Titan's channelling with Echo Stomp makes a good setup for Hookshot if timed correctly.

* Long range disables are really effective against dangerous area controllers and channeling Heroes, like Enigma, Faceless Void or Crystal Maiden, as it may cancel them or prevent enemies from doing further damage while keeping Lion in a relatively safe distance in the warzone.

* Battery Assault, Power Cogs, and Hookshot can interrupt Freezing Field, the latter two being able to go through invisibility should Crystal Maiden use Glimmer Cape.
* Rocket Flare can be used to find Crystal Maiden should she try to hide in the trees to try to safely cast Freezing Field.
* Hookshot allows Clockwerk to easily close in on Crystal Maiden and kill her.

* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.

* Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well.
* Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* Rocket Flare and Jetpack (from purchasing Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.

* Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as Tiny or Spirit Breaker.

* Clockwerk can use Power Cogs to repel Spirit Breaker when he charges in with Charge of Darkness.
* Spirit Breaker's slow 0.6 second attack animation attacks do little damage against Clockwerk. It can also constantly be interrupted by Battery Assault.
* Nether Strike's 1.2 second charge time gives Clockwerk plenty of time to activate Blade Mail and for Battery Assault to cancel it.
Additional:
* Battery Assault will continuously prevent Spirit Breaker from using Nether Strike, Charge of Darkness and even right clicking because of his slow base attack speed.

* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, Tinker, Leshrac, Viper, Skywrath Mage, Lion, Lina, Venomancer.

* Power Cogs prevent Windranger from fleeing with Windrun.
* Battery Assault repeatedly interrupts Focus Fire, disrupting Windranger's damage output.
Additional:
* Windranger cannot escape with Windrun when she is trapped inside Power Cogs.
* Battery Assault repeatedly interrupts Focus Fire, disrupting Windranger's damage output.

* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for Earth Spike & AoE Hex from his level 25 talent.

* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Luna, Puck, Slark, Nyx Assassin, etc.

* Black Hole requires channelling, making it easy to be interrupted with Hookshot.
* Enigma lacks mobility without a Blink Dagger and also is squishy, making him fall easily when ganked by Clockwerk.
Additional:
* Hookshot's stun pierces through spell immunity and Enigma's channeling can be easily cancelled from a safe distance, assuming none of his allies are in the way, and the Black Hole is not centered directly on Enigma.

* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage

Additional:
* Enchantress is very fragile without any form of magic resistance, allowing Lion to easily burst her down.
* Nature's Attendants is a slow heal, making not as much effective against Lion's burst as it could be.
* Her raw movement speed is a fair escape/mobility mechanism, which may allow her to avoid a blindly cast Earth Spike, but does nothing against the rest of Lion's abilities, since they are single target and can't miss.
* Since Lion's damage comes mostly from his skills, Untouchable does nothing to mitigate it.

* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies

* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.

Additional:
* Both Hex and Mana Drain destroy Naga Siren's illusions in an instant, making it hard for her to teamfight or push against a team with Lion. If Lion chooses the AoE effect talent for Hex or the shard for multi-target Mana Drain, it can negate her pushing potential entirely.
* Earth Spike is an AoE disable with good damage. If used well, it can help distinguish the true Naga Siren by the damage they take (illusions take more damage).

* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.

* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.

* Heroes who can stun Sven even with an activated Black King Bar can be an issue: Clockwerk, Beastmaster.

* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.

* Heroes who can stop Axe from getting close will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk

* Power Cogs pushes Monkey King out of Wukong's Command, ending his ultimate.
* Rocket Flare allows Clockwerk to scout Monkey King in the trees, and chase him with Hookshot.

* Clockwerk's long range initiation and catch makes it incredibly difficult for Nature's Prophet to split push and show on the map alone.
* Rocket Flare can be used to scout Nature's Prophet if he is hiding in the forest, and can provide vision inside of Sprout.

* Hex and Mana Drain can be used to immediately destroy Spectre's illusion when she Haunts. A fast fingered Lion can protect himself and a teammate.
* Hex and Earth Spike are good lockdown spells to control and kill Spectre, especially if she doesn't buy defensive items like Linken's Sphere and Black King Bar.
* Finger of Death can be used to burst down Spectre when she is low on life as she has very poor magic resistance.

* Mana Drain depletes Necrophos's mana pool, preventing him from using his abilities.
* Finger of Death deals high magical damage, which becomes amplified by Ghost Shroud.

* Hex greatly reduces Timbersaw's mobility.
* In addition, Lion can follow up with his Earth Spike and Mana Drain combo, preventing Timbersaw to escape with Timber Chain. And he can finish Timbersaw off with Finger of Death if the latter's HP is low enough.

* Meat Hooking a Clockwerk can backfire for Pudge, as Battery Assault and Blade Mail will hurt Pudge more than he hurts Clockwerk.

* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.

* Lion's instant cast point shuts down his initiation and buys time for his allies to catch up.
* Void Spirit has to be cautious when fighting, as he has no protection against Finger of Death. If caught out in a stun, the high magic damage could end him quickly.

* Despite her high mobility, Hex or Earth Spike can lock Phantom Assassin down, make her vulnerable and mitigate her damage output.
* Lion relies entirely on his abilities to be effective, rendering Phatnom Assassin's high evasion through ineffective against him. And Phantom Assassin's low health pool makes her vulnerable to Lion's magical burst without Black King Bar.

* Clockwerk's Battery Assault disables Earth Spirit's Rolling Boulder, while his Power Cogs ensure, that Earth Spirit can't move away from it.
* His Hookshot allows him to chase after Earth Spirit, while using Rocket Flare to gain vision.

* Battery Assault will continuously interrupt Earthshaker's long cast animations.
* Power Cogs can also trap Earthshaker after he initiates.
Additional:
* Battery Assault interrupts Earthshaker's long cast animations, preventing him from using any abilities apart from Echo Slam.
* Power Cogs often separate the battlefield so that both enemies and allies are unlikely to cluster.
* Rocket Flare allows Clockwerk to scout Earthshaker before a fight starts and potentially cancel his Blink Dagger.
* Hookshot enables Clockwerk to catch Earthshaker before he gets a chance to initiate a fight.

* All of Lion's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Hex and Mana Drain can make quick work of whatever illusions you're creating, especially when he acquires his Talents at level 20 and 25.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Earth Spike or Finger of Death with Aghanim's Scepter for the enemy.

* Battery Assault easily interrupts Centaur Warrunner due to his poor cast animation.
* Power Cogs can negate Stampede.

* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion

* Battery Assault's mini-stuns can severely disrupt Legion Commander's attack animation when she enters a Duel, potentially saving Clockwerk (or his allies) and possibly even giving him an edge in securing a win himself.
* Power Cogs pushes Legion Commander away from Clockwerk's allies when she enters a Duel.

* 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.

* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.

* Lion's Mana Drain is a headache for Bristleback to deal with during the laning stage, as it denies him the ability to get last hits with Quill Spray.

* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: Lina, Lion, Zeus

* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.

* Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, Ancient Apparition or Bounty Hunter.

* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion

* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:Lion, Crystal Maiden ,Venomancer etc.

* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion, Anti-Mage

* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, Lion, Shadow Shaman, Invoker, Disruptor and Kunkka.

* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, Dazzle from Aghanim's Shard with upgraded Poison Touch.

* Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, Ancient Apparition or Bounty Hunter.

* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.

* Lion has two low cast point disables (Hex and Earth Spike) to control Ursa before he buys a Black King Bar.
* Hex is one of the few abilities that cannot be dispelled even with an Aghanim's Scepter upgraded Enrage.
* Lion can control Ursa's low mana pool via Mana Drain.

* Heroes who can provide constant vision inside the Roshan Pit can negate one of the strongest advantages of Ursa, which is the possibility of quickly killing Roshan at the early game, with minimum itemization needed (Clockwerk, Beastmaster, etc).

* Pugna's squishiness and lack of mobility make him easy prey for a Hookshot initiation.
* Clockwerk's high health, low mana costs, and lack of reliance on Blink Dagger make Nether Ward ineffective.
* Battery Assault shuts down Aghanim's Scepter upgraded Life Drain, as the repeated ministuns prevent Pugna from channeling for an extended length of time.
Additional:
* Clockwerk loves to Hookshot low health, immobile targets like Pugna.
* Pugna's Life Drain gets immediately and repeatedly (if an Aghanim's Scepter was purchased) cancelled due to Battery Assault, especially if Pugna is trapped inside Power Cogs.
* Clockwerk also loves to build Blade Mail, which will deal more damage to Pugna than Clockwerk due to Pugna's low health pool.
* Finally, both Hookshot and Rocket Flare can allow him to finish off Pugna out of range of his Nether Ward.

* Weaver's exceptional ability to elude and survive through clashes and ganks is hard countered by Lion in every aspect.
* Weaver is very mana dependent and has a rather small mana pool in the beginning of the game, of which Mana Drain can deplete and lessen his early game presence.
* Earth Spike followed by Finger of Death in the huge majority of the time is enough to kill Weaver.
* Earth Spike can be point targeted to hit through Shukuchi.
* Hex's has a fair long duration, by which Weaver will not be able to deal damage, or even survive a coordinated attack, and it is single target, of which cannot be dodged.
* Mana Drain easily breaks Linken's Sphere. Its low cooldown allows Lion to infinitely break it whenever it recharges.
* Earth Spike and Hex when paired for the longer lengths of disables may diminish Time Lapse efficiency, possibly causing Weaver to not undo as much damage as he would.

* Wraith King has a very low mana pool and is extremely dependant on it to cast his high mana cost abilities, so Mana Drain will make him struggle way too hard, even not being able to active his passive ability Reincarnation, forcing the Wraith King to buy Aghanim's Shard as soon as possible.
* Althought Wraith King may not be as fragile to struggle against Lion's damage, it's much easier to disable and harass him, as Wraith King doesn't have any mobility at all, his only gap closer being Wraithfire Blast which costs too much mana for his mana pool, and may only affect one target.
Additional:
* While not being able to confront Wraith King by himself, Lion's Mana Drain helps in draining Wraith King's mana, preventing him from reincarnating unless he has his Aghanim's Shard.
* Lion's Earth Spike and Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Spirit bonuses.

* Rocket Flare can find Tinker if he blinks into the treeline, and Hookshot will prevent him from teleporting out.
* Battery Assault makes Tinker unable to Rearm by stunning him repeatedly.
Additional:
* Clockwerk can easily catch a split pushing Tinker with his Hookshot and prevent him from escaping with Power Cogs and Battery Assault. Clockwerk can also find a Tinker hiding in trees with his Rocket Flare.
* Clockwerk usually buys a Blade Mail, which does lots of damage to Tinker if he gets hit by his abilities (especially March of the Machines).

* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)

* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.

* Mana Drain rapidly saps Morphling's already low mana pool, making him unable to use Waveform or Adaptive Strike. Additionally, Hex prevents these abilities as well.
* An Earth Spike and Finger of Death combo can burst an unwary Morphling down if he has his strength fully shifted to agility.

* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.

* Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as Tiny or Spirit Breaker.

Additional:
* Lion can continuously Mana Drain Tiny in the early game, depleting his small mana pool for his abilities.

* Long range disables are really effective against dangerous area controllers and channeling Heroes, like Enigma, Faceless Void or Crystal Maiden, as it may cancel them or prevent enemies from doing further damage while keeping Lion in a relatively safe distance in the warzone.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.

Additional:
* Clockwerk naturally builds Blade Mail, reflecting Leshrac's high magic damage output back at him.
* Power Cogs will prevent Leshrac from reaching Clockwerk's team and dealing large AOE damage to them.
* Power Cogs will also keep Leshrac close, wasting his Diabolic Edict on just Clockwerk.
* Battery Assault interrupts Leshrac's long cast times of Split Earth and Lightning Storm.

* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.

* Hex and Earth Spike can hold Clinkz down, giving him no chance to use Black King Bar or Skeleton Walk.
* Finger of Death quickly kills Clinkz due to his low health.

* Lion possesses two strong disables in Earth Spike and Hex and heavy magic burst with Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.

* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
