Treant Protector, 
Kunkka, 
Alchemist, 
Troll Warlord, 
Wraith King, 
Tiny, 
Sven.
Tiny
* 
Avalanche and 
Toss will never be enough damage to take out Sven in a clean way.

Nature's Guise and 
Eyes in the Forest.
* Lina has many tools to bypass Living Armor's protection.
Treant Protector
* Timbersaw can use his plethora of tree cutting abilities to level entire sections of the forest, making hiding in the trees more difficult for Treant Protector and his team.
* Timbersaw can easily cut down Treant Protector's Eyes In The Forest once his team has detection. He may even do it unknowingly due to the sheer destructive and chaotic nature of his abilities.
Additional:
* Not only are all of Timbersaw's active abilities capable of cutting down trees, but 
Whirling Death and 
Timber Chain also require it to be effective, counteracting both Treant Protector's Nature's Guise and Eyes in the Forest abilities.

Reaper's Scythe will turn Tiny's high health against him.
* 
Heartstopper Aura does substantial damage to Tiny as a result of his high max health.

* 
Chaos Bolt and 
Reality Rift makes Tiny's low mobility non existent.
* 
Chaos Strike means Chaos Knight will most likely survive longer in a duel between the two because Tiny has much lower attack speed.
* Chaos Knight has a 3.2 strength growth, making him one of the most tanky heroes and a very difficult target for Tiny to burst.
Treant Protector
* Nature's Prophet's Nature's Call can destroy trees that Treant Protecter is hiding in, revealing him.
Tiny
* Invoker is a big problem for Tiny the whole game because of its multiple disables. For example, the 
Cold Snap ability can catch an attack from Tiny's hand by surprise, because it becomes slower with the pumping of 
Grow. has a giant deceleration, creating a condition for the kite, which Tiny is very afraid of. In addition, Invoker has a 
Deafening Blast that disables Tiny's main weapon - strong blows from the hand
Additional:
* Invoker is a big problem for Tiny the whole game because of its multiple disables. For example, such as 
Tornado + 
E.M.P. create unrealistic conditions for Tiny with mana, which is very necessary for Tiny at least for some attacks in a fight. The Cold Snap ability can catch an attack from Tiny's hand by surprise, because it becomes slower with the pumping of Grow. has a giant deceleration, creating a condition for the kite, which Tiny is very afraid of. In addition, Invoker has a Deafening Blast that disables Tiny's main weapon - strong blows from the hand
Tiny
* Tiny's nonexistent armor in the early game makes him very vulnerable to 
Quill Spray's large amounts of physical damage.
* 
Bristleback decreases Tiny's high burst damage against Bristleback.
* 
Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.
Treant Protector
* 
Doppelganger can dispel Leech Seed. It can also destroy large amounts of trees, counteracting Nature's Guise and Eyes in the Forest.
Tiny
* Primal Roar and the slow from Boars make kiting Tiny very easy.
Treant Protector
* 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.
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like 
Phantom Assassin and 
Tinker are very effective because of Tiny's low attack speed. Additionally, 
Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (
Clinkz, 
Templar Assassin, 
Ursa, Wraith King etc).
Treant Protector

Riki, Treant Protector, etc.
Treant Protector
* Heroes with invisibility will be detected by Thirst when they have low enough health: 
Bounty Hunter, Templar Assassin, Riki, Clinkz, 
Weaver, Treant Protector, 
Nyx Assassin.
Treant Protector
* Heroes with the capability of removing or destroying trees greatly hinders the effectiveness of Treant Protector's abilities: 
Batrider, 
Nature's Prophet, 
Lina, 
Enigma, 
Mars
Treant Protector
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, Enigma, 
Faceless Void, 
Invoker, 
Lich, 
Magnus, Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain,

Tusk and Phoenix, will greatly limit his Physical damage output.
Treant Protector
* Heroes with the capability of removing or destroying trees greatly hinders the effectiveness of Treant Protector's abilities: Batrider, Nature's Prophet, Lina, Enigma, Mars
Tiny
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Tiny
* Heroes with high base damage (
Morphling, Tiny, 
Drow Ranger), heroes with mana burning abilities (
Anti-Mage), and 
Diffusal Blade users (
Juggernaut or Riki) will suffer from Reflection's illusions.
Tiny
* 
Blade Fury protects Juggernaut from all of Tiny's magic burst damage.

Shadow Demon, 
Dazzle, 
Oracle, 
Bane, 
Pugna, Tusk, Winter Wyvern, 
Io, Underlord, Treant Protector and 
Keeper of the Light.
Treant Protector
* Monkey King is one of the few other heroes who can easily traverse through trees, counteracting Treant Protector's ability to hide in trees.
Treant Protector
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: 
Bloodseeker, Treant Protector with Eyes In The Forest, 
Sniper, Weaver
Tiny
* Tiny can be a serious problem for the distance between Lone Druid and his 
Summon Spirit Bear with his Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself
* Lone Druid will not always be in his 
True Form, since she has her own recharge, which is why Tiny can find him with a 
Shadow Blade or 
Blink Dagger and kill him in a second with a combination of Avalanche and Toss, due to the fact that Lone Druid has a very small health reserve without True Form

Treant Protector
* Clinkz, Sniper, 
Lone Druid, Troll Warlord, 
Legion Commander and Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Tiny
* Avalanche and Toss combo makes short work of 
Mirror Image's illusions.
* Tiny's cleave with Tree Grab and area of effect damage with Tree Volley will easily wipe out illusions.
Treant Protector
* Treant can give chase should Hoodwink attempt to 
Scurry away, and 
Nature's Grasp can slow her down so Treant Protector's teammates can pin Hoodwink down.
Treant Protector
* Treant Protector can usually scout out Magnus in the trees with Eyes in the Forest and disrupt his initiation attempts. He can also counter Magnus' initiation with 
Overgrowth.
Treant Protector
* Anti-Mage relies on blinking and attacking. Overgrowth prevents both.
* Be wary that he will eventually farm up a 
Manta Style that fully dispels Overgrowth. Good players will wait for your ultimate to use their manta. Perhaps an ally has a silence or similar that would force him to use his manta before your ultimate.
Treant Protector
* If 
Storm Spirit is caught in an Overgrowth, he is shut down.
* With the exception of 
Electric Vortex, he won't be able to cast any relevant skill.
Tiny
* Toss and Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's 
Essence Shift permanent agility steal does not do much against him.
Treant Protector
* Nature's Grasp severely slows down Spirit Breaker, reducing effects of Charge of Darkness and Greater Bash.
* Living Armor can mitigate a large portion of Spirit Breaker's damage since his attacks are slow.
* Treant Protector can also counter-initiate against Spirit Breaker with 
Leech Seed, Overgrowth and with his root from 
Aghanim's Shard upgraded Nature's Guise before he manages to escape.
* 
Aghanim's Scepter gives Treant Protector access to Eyes In The Forest ability, which allows him to turn trees into wards that provide vision, allowing him to keep his allies warned about Spirit Breaker's attempts to gank them. Eyes In The Forest will also trigger Overgrowth if Spirit Breaker is in range of the tree affected by it.
Additional:
* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.
Treant Protector
* Living Armor and Leech Seed can be used to save a hero from a 
Relocate gank.
* Overgrowth can be used to cancel escape attempts with Relocate.
* Once Treant Protector buys Aghanim's Scepter, he will gain access to Eyes in the Forest, that will allow him to enchant a tree which will grant him unobstructed vision in that location, allowing him to keep his allies alerted on Io and his 
Tethered's attempts to gank them, and which can also allow Overgrowth to damage them and root them if they are within a 800 radius of an tree affected by Eyes in the Forest.
Treant Protector
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, 
Meepo, 
Crystal Maiden, 
Dark Willow, Underlord, 
Naga Siren
Treant Protector
* Overgrowth has a great duration, which prevents the units caught from attacking, moving and Blinking. Heroes like Storm Spirit, 
Mirana, Anti-Mage and others won't be able to do much if they're caught.
Treant Protector
* Treant Protector grants protection against his attacks with Living Armor and his ultimate, Overgrowth is a massive AoE disarm and root that pierces spell immunity, causing trouble to Lycan. You will find yourself in need of an ally's dispel or forced to pop 
Black King Bar for its dispel.
Additional:
* Lycan has no kind of teleport, being only able to walk, and heavily relies on his attacks. As Overgrowth roots and disarms the targets, Lycan can't do much in an overgrowth field.

* Squishy heroes, usually supports, like 
Lion, 
Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Treant Protector

Tiny
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, 
Ogre Magi.
Treant Protector
* Treant Protector's Living Armor will also negate Tidebringer's damage.
Tiny
* Tiny's Avalanche affects all Meepos and Toss can send a singular Meepo into death.
Additional:
* Avalanche and Toss prevents Meepo's from using 
Poof to escape.
* Tiny doesn't need to target the weakest clone while he is affected by Tree Grab.
Treant Protector

Treant Protector
* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Treant Protector
* Overgrowth prevents Phantom Assassin from using 
Blink Strike even through her spell immunity.
* Living Armor reduces Phantom Assassin's physical damage whenever she attempts to gank an allied hero.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Treant Protector
* Clinkz will often roam the map alone, and Treant Protector's Nature's Guise allows him to set up kills with his allies on Clinkz from invisibility.
* Treant Protector's very high damage allowing him to trade hits or contest last hits with Clinkz, while Living Armor can be used to sustain the harass.
* Living Armor protects any of Treant's allies ganked by Clinkz.
* In teamfights, Treant Protector's Overgrowth can disarm Clinkz, preventing him from turning invisible and holding him in place even if he has a Black King Bar.
* Leech Seed slows Clinkz, preventing him from repositioning or fleeing away from danger.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Tiny
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, Puck, Tiny, 
Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Tiny
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Treant Protector
* Clinkz, Sniper, Lone Druid, Troll Warlord, Legion Commander and Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Tiny
* 
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.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Treant Protector
* Spiderlings melt away Living Armor almost instantly.
* The vision from Eyes In The Forest may prove dangerous for Broodmother, however.

Pit of Malice: Sven, Tiny, Wraith King, 
Dragon Knight, Meepo, 
Doom, Bounty Hunter, 
Dark Seer, 
Undying, Alchemist, Legion Commander.
Treant Protector
* Heroes that provide vision will see Fiend's Gate coming: 
Techies, Templar Assassin, Treant Protector.
Tiny
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, Tiny and Undying have a very hard time killing Familiars.
Tiny
* Tiny can deal with 
Visage's 
Gravekeeper's Cloak quickly, as Avalanche deals damage in enough instances to completely remove all 4 layers of the passive. With Visage's lower than average Armor, a well positioned stun can allow Tiny to kill Visage easily.
Additional:
* Tiny's Avalanche removes a significant number of layers from Gravekeeper's Cloak. When combined with Toss burns through all of Gravekeeper's Cloak while doing triple times Toss damage to Visage in midair.
* Tiny's already high damage coupled with 
Tree Grab's attack modifier will make short work of Visage's Familiars.
Tiny
* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
