* Heroes with strong dispels can remove Primal Roar's stun: Abaddon, Slark, Oracle.

* Pounce prevents Tinker from blinking away.
* Slark frequently builds Shadow Blade, which allows him to approach Tinker unnoticed. Since Tinker's farming usually covers a significant amount of area on the map, Sentry Wards may not be cost effective.
* Shadow Dance allows Slark to detect both common and unusual wards. Eliminating common ward causes Tinker trouble farming many lanes if he does not know who may be waiting to jump on him. Slark is also uniquely able to identify some of the less common wards used by Tinker, such as those placed on the cliffs at map edges which Tinker uses to give him vision over the trees he uses to hide in.
* Slark's extremely high move speed from Shadow Dance, potentially stacked with Shadow Blade, allows him to easily follow Tinker between lanes, especially if Tinker has pushed the lanes out.
* Dark Pact dispels Laser's blind.

* As Tinker relies heavily on his spells to be effective, Last Word and Global Silence will render him largely useless.
* Arcane Curse effectively prevents Tinker from casting spells during its duration, as he will otherwise suffer heavy damage.
* Glaives of Wisdom deal pure damage, which make quick work of fragile heroes like Tinker.
* Silencer's intelligence steal permanently weakens Tinker since he's a hero who requires lots of mana to be effective.
Additional:
* Silencer can stop Rearm, preventing Tinker from spamming his abilities/items or escaping.

* His whole skillset acts like a counter to Tinker:
* Impale prevents Tinker from blinding Nyx Assassin or fighting back, while giving Nyx' allies time to catch up to Tinker's position.
* Mana Burn generally deals more damage to intelligence based heroes like Tinker
* Spiked Carapace can stun Tinker at a moment of Nyx Assassin's choosing if March of the Machines has been cast. It is also quite easy to time Spiked Carapace against Heat Seeking Missiles.
* Vendetta allows Nyx to approach Tinker in the trees or wait for him in common hiding spots and deal heavy damage to his low armor.
Additional:
* March of the Machines and Heat-Seeking Missile allow easy Spiked Carapace stuns.
* As a fragile hero that relies on mana and intelligence items, Tinker is vulnerable to Mana Burn.
* Nyx Assassin's stuns can interrupt Rearm and leave Tinker helpless.

* Having many summons out will cause Echo Slam to deal extra damage.

* Aphotic Shield effectively nullifies Primal Roar's single-target initiation on allies.
* Even being initiated by Primal Roar, Borrowed Time can make Abaddon extremely difficult to kill.
Additional:
* Primal Roar can be instantly dispelled by Aphotic Shield.
* The debuffs from Wild Axes and Poison from Call of the Wild: Boar can also be dispelled by Aphotic Shield.

* False Promise effectively nullifies Primal Roar's single-target initiation on allies.
* Purifying Flames kills Beastmaster's Hawk instantly and Boar with two casts.

* Chen can take control of the Boar from Call of the wild Boar at any time.

* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.

* Due to Tinker's low health pool, Zeus can easily burst Tinker down, while also cancelling Rearm.
* Once Zeus gets Aghanim's Scepter, he will gain Nimbus, which allows him to scout out Tinker on the map, especially when he is pushing lanes while hiding in the trees.
Additional:
* Zeus can easily reveal Tinker's location in the trees with Thundergod's wrath.
* When Zeus has an Aghanim's Scepter, he can use his Nimbus, together with Lightning Bolt to interrupt Tinker's Boots of Travel channelling and cancel Tinker's Blink Dagger.

* Meat Hook can be used to pull Tinker to Pudge while he is hiding in the trees, and a follow up with Dismember and Rot can lead to a valuable kill, as Tinker doesn't buy many survivability items.
* Flesh Heap makes it hard for Tinker to deal serious damage.
Additional:
* He can Meat Hook a Tinker hiding in the trees and follow it up with Dismember and Rot for an easy solo kill, as Tinker doesn't tend to buy survivability items.
* His innate magic resistance and huge health pool from Flesh Heap makes it hard for Tinker to deal serious damage to Pudge.

* Clockwerk can easily catch a split pushing Tinker with his Hookshot and prevent him from escaping with Power Cogs and Battery Assault.
* He can 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).
Additional:
* 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.

* His global teleportation with Boots of Travel and Rearm is easily countered with Haunt, and Spectre can reach him anywhere on the map.
* He is squishy, and if alone Desolate will kill him very fast.
* Laser's blind isn't reliable, since Desolate cannot miss. Even worse, Dispersion can reflect and reduce his burst damage.

* Tinker relies on his high mobility from Boots of Travel and Blink Dagger to survive. Those items don't help him if Spirit Breaker manages to cast Charge of Darkness on him.
* Spirit Breaker can easily cancel Rearm and Boots of Travel.

* Tinker is heavily reliant on casting his spells and Doom can disable all of his abilities and items. An Aghanim's Scepter only makes it harder for Tinker to survive.
Additional:
* Tinker is heavily dependent on active abilities and Doom prevents him from using any of them.

* Heroes with AoE abilities are a bane to Beastmaster's summons: Storm Spirit, Magnus, Pangolier.

* Storm Spirit destroys trees and ignores impassable terrains with Ball Lightning, rendering them dangerous places for Tinker to hide within.
* Ball Lightning disjoints projectile from Heat-Seeking Missile and damage from March of the Machines.
* Electric Vortex prevents Tinker from teleporting away, and Static Remnant and Overload can easily burst him down.
Additional:
* He can easily catch Tinker in the trees with Ball Lightning and kill him with Orchid Malevolence and his abilities, which deal both physical and magical damage, making them difficult for Tinker to itemize against.

* Tinker is an easy target for Earth Spirit to initiate on. He likes to split push lanes once he acquires Boots of Travel and Earth Spirit can jump him with his Rolling Boulder and disable him to buy enough time for his teammates to come and assist Earth Spirit.
* The huge range of Stone Remnant and Rolling Boulder enables Earth Spirit to stop Tinker from teleporting to his fountain since Tinker tends to buy Blink Dagger most of the time to escape.

* Illuminate clears Beastmaster's summons and is effective against his push.

* Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.

* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.

* Heroes who summon multiple units that are not spell immune. Nature's Prophet,Lycan,Beastmaster

* Anti-Mage's high mobility from Blink and tendency to build Battle Fury makes him strong against split-pushing heroes: Nature's Prophet, Tinker, and Arc Warden.

Additional:
* Tinker is fragile and vulnerable against carries like Anti-Mage.
* Mana Break burns away his mana pool and deals bonus physical damage.
* Tinker's massive mana pool makes Mana Void deal large amount of damage, and can be used to cancel a Boots of Travel teleport.
* Blink gives Anti-Mage many options, like disjointing Heat Seeking Missiles. He can use Blink to wait out of sight for a split pushing Tinker or chase a blinking Tinker into trees.
* Tinker doesn't want any of his spells reflected back at him through Counterspell.

* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.

* Heroes with summoned units don't fare well against Dawnbreaker. (Phantom Lancer ,Beastmaster ,Lycan)

* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.

* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.

* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
* In general, highly mobile heroes like Earth Spirit or Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.

Additional:
* X Marks the Spot can be used to prevent Tinker from escape with Blink Dagger or Boots of Travel, discourage him from snapping farm and snapping gank. However, in later game, it'll be much more difficult because Tinker can buy Black King Bar or Linken's Sphere to prevent Kunkka from placing X on him, or Eul's Scepter of Divinity to prevent the recall

* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider

* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider

* Reactive Armor is very effective against Beastmaster's summons during laning stage and entire game.
* Timbersaw can quickly clear Beastmaster's summons with his nukes.

* Timbersaw's ability to destroy trees can be a serious problem for some heroes that use them, as either a way of enhancing their spells like Treant Protector, or heroes that tend to hide inside of them like Tinker and Monkey King.

* Wave of Terror can reveal a Tinker attempting to hide in the trees and then Nether Swap and Magic Missile will both serve to interrupt/lock him down, should he attempt to town portal or reload.

* Frostbite kills boars instantly on the laning stage leading to either experience lead or disabling Beastmaster from using Boar
* Crystal Nova nukes and slows down the attack and movement speed of Beastmaster's summons.
* Freezing Field grants improved self armor, nukes and slows down Beastmaster and his summons.

* Press the Attack can dispel Laser's blind while providing great attack speed and health regeneration.
* Once caught in a Duel, Tinker, who completely relies on his spells to be effective, has little chances of survival with his low health pool and armor.

* Night Stalker can easily find Tinker in the trees during Dark Ascension.
* Void's mini-stun will stop Rearm and Boots of Travel.
* Crippling Fear's silence will prevent Tinker from fighting back, as Tinker relies on his spells.
Additional:
* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.

* Untouchable negates Inner Beast's attack speed bonus, making her hard to kill even if stunned by Primal Roar.
* Enchantress can also take control of Beastmaster's summons.
Additional:
* Enchant can control Beastmaster's boars, mitigating his effectiveness during the laning stage and teamfights.

* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.

* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, Bloodseeker, Clockwerk, Doom, Shadow Shaman.
