* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit,
Morphling,
Ember Spirit
Viper
* Ball Lightning allows Storm Spirit to escape through Viper Strike, wasting Viper's mana.

* Viper cannot interrupt heroes with powerful channeling abilities: Bane,
Enigma,

Lion,
Zeus
Viper
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion,
Anti-Mage
Broodmother
[wiki] rating: 1.0 (winrate: 56% pickrate: 2%)Viper
* Viper's lack of escape and durability means he can be ran over in a laning stage by Spiderlings.
* Broodmother can bring Viper down quickly with Insatiable Hunger activated.
Pugna
[wiki] rating: 1.0 (winrate: 53% pickrate: 4%)Viper
* Pugna's Decrepify allows him to save allies from being ganked by Viper, since Viper mostly relies on direct attacks in order to deal damage.
* Nether Ward can discourage Viper from spamming his abilities.
* Viper's damage over time is not enough to kill Pugna as he will have more than enough time to save himself (or his allies) with Life Drain and Viper has no solutions to cancel it.
* Pugna has no passive abilities, which renders Nethertoxin nearly useless.
Juggernaut
[wiki] rating: 1.0 (winrate: 52% pickrate: 18%)Gyrocopter
* Blade Fury and
Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.
Elder Titan
[wiki] rating: 1.0 (winrate: 52% pickrate: 1%)Viper
* Viper is an agility hero, and his item build mostly includes agility items, so Natural Order can be devastating, removing all armor and greatly decreasing the effectiveness of Corrosive Skin, weakening Viper's magic resistance. Additionally, Echo Stomp and Earth Splitter deal both magical and physical damage, and can help bringing Viper down fast.
* Aghanim's Scepter may be necessary to take Viper down due to
Nethertoxin's break.
Weaver
[wiki] rating: 1.0 (winrate: 50% pickrate: 8%)Viper

* Viper Strike can be countered through Snowball, wasting Viper's mana through his ultimate.
Queen of Pain
[wiki] rating: 1.0 (winrate: 48% pickrate: 9%)Gyrocopter

* Sonic Wave is very effective at ganking Gyrocopter in the early game.
Rubick
[wiki] rating: 1.0 (winrate: 47% pickrate: 17%)Viper
* If Rubick can use Spell Steal to take Nethertoxin, he will be able to disable Corrosive Skin, reducing much of Viper's durability.
* He can also steal Viper Strike, which can be used to hinder a hero on your team (or multiple heroes, if Rubick has Aghanim's Scepter).
Witch Doctor
[wiki] rating: 1.0 (winrate: 46% pickrate: 13%)Viper
* Voodoo Restoration heals to counter damage over time of Viper abilities.
* Viper has no way to cancel Death Ward, even through Rod of Atos.
Faceless Void
[wiki] rating: 1.0 (winrate: 41% pickrate: 4%)Gyrocopter
* Time Walk makes it hard for Gyrocopter to pin down Faceless Void. With
Backtrack it also negates most of his attacks.
* Time Dilation will prevent Gyrocopter from using his cooldown spells.
Beastmaster
[wiki] rating: 0.6 (winrate: 56% pickrate: 7%)Viper
* Illusion or summon-based heroes can be a problem to Viper due to his lack of AoE damage: Naga Siren,
Phantom Lancer,

* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz,
Pugna,
Nature's Prophet,

Tusk
Additional:
* Clinkz does not have any passive abilities at all, making Nethertoxin nearly useless.
* Viper's Corrosive Skin provides no protection against Clinkz's physical damage output.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden,
Enchantress,
Gyrocopter,
Lion,
Riki,
Techies,
Terrorblade,
Necrophos,
Invoker.
Anti-Mage
[wiki] rating: 0.6 (winrate: 47% pickrate: 14%)Gyrocopter
* Mana Break makes Gyrocopter, who has low mana pool, unable to use his abilities that most of his damage output depends on.
* Counterspell negates magical damages from Gyrocopter and it can also reflect Homing Missile back to himself.
* Anti-Mage can easily escape from Gyrocopter's attack range and Call Down with Blink.
Viper
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion,
Anti-Mage
Viper
* Viper's skill set makes him an effective early game ganker against Anti-Mage before he is sufficiently farmed.
* Viper's Corrosive Skin and low mana pool causes him to take little damage from Mana Void.
* Nethertoxin disables Mana Break and Counterspell, weakening both his offense and defense.
Snapfire
[wiki] rating: 0.6 (winrate: 47% pickrate: 6%)Gyrocopter

Nature's Prophet,
Dark Seer,
Lycan,

Wraith King
[wiki] rating: 0.4 (winrate: 52% pickrate: 18%)Viper
* Viper's Nethertoxin cannot disable Reincarnation, which could put him in disadvantage against Wraith King if his whole team is with him.
* In addition, Viper doesn't like buying Diffusal Blade, which is the only item that can help him against Wraith King.
* Wraith King's high burst damage allows him to kill Viper before being killed.
Viper
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
Omniknight
[wiki] rating: 0.4 (winrate: 51% pickrate: 1%)Gyrocopter
* Guardian Angel negates most of Gyrocopter's physical АоЕ damage.
* Heavenly Grace dispels Homing Missile stun.
Viper
* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper,
Venomancer,
Clinkz
Windranger
[wiki] rating: 0.4 (winrate: 50% pickrate: 16%)Viper
* Windrun evades Poison Attack and counteracts the slow.
* Viper's low mobility makes him an easy Shackleshot target.
* Focus Fire grants Windranger significant physical damage output to quickly wear Viper down.
* Powershot is a strong harassment and zoning tool against Viper in lane.
Viper
* 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.
Meepo
[wiki] rating: -2.0 (winrate: 46% pickrate: 1%)Viper
* Nethertoxin prevents the lifesteal from Ransack. The silence from Viper's level 25 talent also prevents Meepo escaping with Poof.
* Meepo and his clones have a lack of magic resistance, so they're vulnerable to Poison Attack &
Viper Strike directed onto one clone.
Gyrocopter
* Flak Cannon and Call Down will shred Meepo's clones.
* Homing Missile can catch and single out retreating Meepos, making them an easy kill.
Axe
[wiki] rating: -1.6 (winrate: 47% pickrate: 9%)Gyrocopter
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe,
Dragon Knight,
Sven.
Viper
* Poison Attack and
Viper Strike slows Axe significantly, and puts his
Blink Dagger on cooldown, preventing him from initiating.
* Nethertoxin can break Counter Helix.
Additional:
* Nethertoxin prevents Counter Helix from triggering, which significantly lowers Axe's damage output in the early to mid game.
* Viper's various slows and damage over time prevents Axe from initiating as well as putting his Blink Dagger on cooldown.
Dragon Knight
[wiki] rating: -1.6 (winrate: 48% pickrate: 3%)Gyrocopter
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe,
Dragon Knight,
Sven.
Viper
* In the early game, a Dragon Knight without Black King Bar is basically defenseless against Viper.
Additional:
* Dragon Knight is easily harassed by Poison Attack after the laning stage ends.
* Corrosive Skin protects Viper from Breathe Fire and returns damage.
* Nethertoxin mitigates Dragon Blood, Dragon's Knight main source of armor and health regeneration.
* Between Poison Attack and Viper Strike, Viper can keep Dragon Knight permanently slowed even in Elder Dragon Form.
Templar Assassin
[wiki] rating: -1.6 (winrate: 51% pickrate: 5%)Viper
* The damage over time from Viper's Poison Attack and
Viper Strike rapidly wear down Refraction charges, allowing Templar Assassin to be damaged. Additionally,
Corrosive Skin causes her attacks to apply damage over time on her as well.
* Nethertoxin is a big threat to Templar Assassin. Her initially low range making it very hard to deal against Nethertoxin in laning phase. At any stage of the game, a Nethertoxin can always force her to undo her Meld.
Additional:
* All of Viper's abilities quickly burn through Refraction charges.
* Templar Assassin's short range, aside from Psi Blades' spill damage, makes her vulnerable to Poison Attack harassment.
* Templar Assassin traditionally forgoes health and armor items for damage. Outside of Black King Bar, Viper will almost always be able to kill her when
Refraction is down.
Gyrocopter
* Weak damage but high tick rate or persist in a long time: Slark,
Gyrocopter,
Queen of Pain,
Shadow Shaman (
Shackles),
Pugna
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo,
Witch Doctor,
Lycan,
Enigma,
Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer,
Chaos Knight,
Naga Siren (bonus for her
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark,
Gyrocopter,
Queen of Pain,
Shadow Shaman (
Shackles),
Pugna
Visage
[wiki] rating: -1.6 (winrate: 51% pickrate: 1%)Viper
* Nethertoxin cuts off Gravekeeper's Cloak, Visage's primary defense mechanism.
* Viper can ignore Grave Chill's attack speed slow with his magic damage output.
Additional:
* Since Visage is a slow hero, Viper can easily kite him with
Poison Attack and
Viper Strike while successfully chipping away at Gravekeeper's Cloak.
* Nethertoxin removes all layers of Gravekeeper's Cloak, leaving Visage exposed.
* Corrosive Skin makes Viper highly resistant to Soul Assumption.
Gyrocopter
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like Gyrocopter,
Kunkka,
Magnus and
Medusa.
Sven
[wiki] rating: -1.2 (winrate: 43% pickrate: 1%)Gyrocopter
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe,
Dragon Knight,
Sven.
Viper
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
Tiny
[wiki] rating: -1.0 (winrate: 45% pickrate: 6%)Viper
* Tiny has low movespeed and attack speed, making him vulnerable to Viper's slows.
* Corrosive Skin provides magic resistance to lower Tiny's magic burst damage.
Magnus
[wiki] rating: -1.0 (winrate: 46% pickrate: 4%)Viper
* Most of Magnus' abilities except Empower will trigger damage through Corrosive Skin.
* Poison Attack and Viper Strike can slow Magnus during Skewer, as well as putting his
Blink Dagger on cooldown, preventing him from initiating or re-initiating.
Shadow Fiend
[wiki] rating: -1.0 (winrate: 46% pickrate: 18%)Viper
* Nethertoxin breaks both Necromastery and Presence of the Dark Lord, reducing his damage massively.
* Corrosive Skin gives Viper bonus Magic Resistance against Shadowraze and Requiem of Souls.
* Viper can easily take advantage of Shadow Fiend's lack of escape and mobility spells with Viper Strike and
Poison Attack. Poison Attack also serves as a great way to harass Shadow Fiend.
Phantom Assassin
[wiki] rating: -1.0 (winrate: 46% pickrate: 15%)Viper
* Assuming they have not bought anti-evasion items, attack dependent heroes such as Viper,
Ursa or
Clinkz can be a minor threat for Phantom Assassin early in the game, and may even be completely dominated by her thanks to her evasion.
Viper
* Nethertoxin breaks Phantom Assassin's passive skills.
* Viper Strike goes through
Black King Bar.
Gyrocopter
* Heroes with magical burst damage can often kill Phantom Assassin before she gets to do much: Necrophos,
Nyx Assassin,
Gyrocopter.
Bristleback
[wiki] rating: -1.0 (winrate: 46% pickrate: 9%)Viper
* Nethertoxin disables Bristleback's passive.
* Viper Strike and
Poison Attack slow down Bristleback's movement speed so he's unable to get out from Nethertoxin.
Additional:
* Nethertoxin's break removes Bristleback and prevents
Warpath from building stacks. Besides losing his eponymous defensive passive, Bristleback also lose his ability to build up damage over lengthy battles.
* Viper can perpetually kite Bristleback with Poison Attack and Viper Strike.
Doom
[wiki] rating: -1.0 (winrate: 46% pickrate: 3%)Viper
* The slow applied from Corrosive Skin offsets the movement speed bonus granted by Scorched Earth and the tick-based damage from Infernal Blade and Doom will continually slow Doom down. This allows Viper, much like Sniper, to 'kite' Doom and keep him at a safe distance between the two. Additionally,
Corrosive Skin applies an attack-speed slow which is fairly crippling to a hero such as Doom that, naturally, has a high base attack-time, poor agility gain and builds little attack-speed items.
* Since Doom does not disable auto-cast abilities, Viper's Poison Attack will continue to work. Doom may find it hard to close the distance between himself and Viper, and thusly difficult to effectively lockdown and continually deal damage through his abilities.
Slark
[wiki] rating: -1.0 (winrate: 47% pickrate: 13%)Viper
* Nethertoxin negates Essence Shift and the regeneration aspect of
Shadow Dance.
* Dark Pact doesn't mean a lot against Viper's ubiquitous slows.
* Viper becomes a relevant presence in team fights before Slark can procure his standard items (e.g. Shadow Blade).
Spectre
[wiki] rating: -1.0 (winrate: 47% pickrate: 3%)Viper
* Nethertoxin disables Desolate and
Dispersion, leaving Spectre with far less damage output and damage mitigation in engagements.
* Spectre is one of the weakest heroes at early levels. Viper can stifle her farm with early fights before Spectre purchases any major items.
Additional:
* Nethertoxin removes passives, negating Spectre's damage and survivability by removing both Dispersion and Desolate.
* Due to Haunt and Radiance's burn, Spectre is heavily susceptible to being persistently slowed and damaged by Corrosive Skin without even directly attacking Viper.
* Poison Attack and
Viper Strike further slow Spectre's movement speed to a crawl, while his improved magic resistance means he can easily shrug off Radiance's burn.
Mars
[wiki] rating: -1.0 (winrate: 48% pickrate: 15%)Viper
* Nethertoxin breaks the damage block from Bulwark.
* Poison Attack and
Viper Strike's slows make it difficult for Mars to contribute to fights due to his low mobility.
Additional:
* Nethertoxin breaks Bulwark entirely, making Mars far less tanky. Using Nethertoxin inside
Arena of Blood may discourage enemies from following up with Mars' initiation.
* Rod of Atos is currently common on Viper and keeps Mars in position long enough to be killed.
* Viper is not very tanky earlier in the game, so positioning against Mars is important since a well-timed Spear of Mars can be the end of Viper.
Vengeful Spirit
[wiki] rating: -1.0 (winrate: 48% pickrate: 4%)Viper
* Nethertoxin disables Vengeance Aura.
* Vengeful Spirit has no mobility spells aside from Nether Swap, which Viper can take advantage of with his slows.
* Viper can easily bully Vengeful Spirit out of a lane with Poison Attack.
Additional:
* Nethertoxin prevents attack damage bonus from Vengeance Aura and the components of
Nether Swap.
* Both Magic Missile and
Wave of Terror are counteracted by Corrosive Skin, making Vengeful Spirit's fighting harder against Viper.
Sniper
[wiki] rating: -1.0 (winrate: 48% pickrate: 6%)Viper
* Nethertoxin breaks Sniper's passives.
* Viper Strike together with
Poison Attack can slow Sniper and tears through his low health and mobility.
Disruptor
[wiki] rating: -1.0 (winrate: 49% pickrate: 9%)Viper
* Corrosive Skin minimizes the damage Viper takes from all of Disruptor's skills.
Undying
[wiki] rating: -1.0 (winrate: 50% pickrate: 5%)Gyrocopter
* Flak Cannon rips through Tombstone's zombies.
Additional:
* Flak Cannon enables Gyrocopter to clear the zombies easily.
Riki
[wiki] rating: -1.0 (winrate: 50% pickrate: 15%)Viper
* Viper's Nethertoxin disables Cloak and Dagger, negating Riki's invisibility and much of his damage. It also makes him more vulnerable to magic damage, which does not go well with Riki's low health pool. With the talent applied, he can't even blink to safety or hide with Tricks of the Trade.
* Corrosive Skin makes it hard for Riki to chase Viper and attack him due to the attack speed slow.
* Viper Strike stays on Riki even after he goes invisible.
* Poison Attack makes it risky for Riki to get last hits and can make the laning phase difficult for him.
Earthshaker
[wiki] rating: -1.0 (winrate: 50% pickrate: 15%)Viper
* Poison Attack and
Viper Strike allowing to kite and slow Earthshaker significally, putting
Blink Dagger on cooldown and preventing him from initiating or re-initiating.
* Nethertoxin breaks Aftershock. The silence from Level 25 talent also prevents Earthshaker from initiating or re-initiating.
Additional:
* Being a melee hero, Earthshaker's movement is liable to suppression by Poison Attack and Viper Strike.
* Earthshaker's kit, with the exception of Enchant Totem, deals magic damage. Corrosive Skin effectively blunts his killing potential with a standard Blink combo among other things.
* Nethertoxin disables Aftershock, which removes the stun and bonus damage from
Enchant Totem and
Echo Slam. Additionally the level 25 talent will silence Earthshaker, making him vulnerable to Viper's teammates without stuns.
Phoenix
[wiki] rating: -1.0 (winrate: 50% pickrate: 9%)Viper
* Corrosive Skin gives Viper additional resistance to Phoenix's magical damage, and since they deal damage over time, Phoenix would be constantly afflicted by his passive's own debuff, making him not an ideal target for Phoenix's harassment. Phoenix's abilities also constantly drain its own health away, becoming more vulnerable to
Poison Attack.
Venomancer
[wiki] rating: -1.0 (winrate: 50% pickrate: 5%)Viper
* Corrosive Skin means Viper can often outlast Venomancer in a battle of attrition.
* Venomancer has no mobility without items, which makes him vulnerable to constant slows.
Ogre Magi
[wiki] rating: -1.0 (winrate: 50% pickrate: 15%)Viper
* Nethertoxin breaks Multicast.
* Corrosive Skin minimizes the damage during Ignite and Fireblast.
Necrophos
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)Viper
* Nethertoxin prevents Heartstopper Aura from dealing damage or healing Necrophos.
* Viper's magic damage is amplified whenever Ghost Shroud is used.
* Corrosive Skin makes Viper tankier against Death Pulse and
Reaper's Scythe.
Tidehunter
[wiki] rating: -1.0 (winrate: 51% pickrate: 9%)Viper
* Nethertoxin cancels out Kraken Shell and stops the hard dispel from passively activating, preventing Tidehunter from functioning as a frontline tank.
* Anchor Smash is mostly irrelevant against a ranged hero.
* Tidehunter relies on the threat of Ravage, which has an obscenely long cooldown. Viper can exploit the downtime with his short cooldowns.
Monkey King
[wiki] rating: -1.0 (winrate: 51% pickrate: 17%)Viper
* Nethertoxin prevents the buildup of Jingu Mastery stacks.
* Viper's poison magical damage-over-time stops Monkey King from using Tree Dance. It also ignores the extra armor bestowed by Wukong's Command.
Additional:
* Nethertoxin prevents the buildup of Jingu Mastery stacks.
* Monkey King's high base movement speed is of little worth against the array of slows Viper possesses.
* All of Viper's magical damage over time stops Monkey King from using Tree Dance. It also ignores the extra armor bestowed by
Wukong's Command.
Ursa
[wiki] rating: -1.0 (winrate: 51% pickrate: 16%)Viper
* Nethertoxin breaks Fury Swipes, making Viper a decent counter to Ursa in a laning stage.
* Viper Strike is a strong, undispellable slow, making it much easier to kite Ursa for everyone.
Ancient Apparition
[wiki] rating: -1.0 (winrate: 52% pickrate: 9%)Viper
* Corrosive Skin minimizes the damage Viper takes from all of Ancient Apparition's abilities.
* Ancient Apparition's slow movement speed, squishy nature, and lack of escape abilities can easily be taken advantage of through Poison Attack and
Viper Strike.
Abaddon
[wiki] rating: -1.0 (winrate: 53% pickrate: 4%)Viper
* Because Poison Attack has a low cooldown at all levels, Aphotic Shield is ineffective as a hard dispel.
* Nethertoxin prevents Borrowed Time from activating passively and blocks
Curse of Avernus
Bounty Hunter
[wiki] rating: -1.0 (winrate: 54% pickrate: 9%)Viper
* Viper's poison abilities can slow Bounty Hunter's movement speed and allows to chase him with True Sight items.
* Nethertoxin can break Jinada, and the silence from level 25 prevents Bounty Hunter from using all of his spells.
Nyx Assassin
[wiki] rating: -1.0 (winrate: 54% pickrate: 14%)Viper
* Corrosive Skin minimizes the damage from Impale and
Mana Burn.
* Nyx Assassin cannot survive several poison damage-over-time, even Spiked Carapace is activated.
* However the Vendetta break can be dangerous for Viper.
Razor
[wiki] rating: -1.0 (winrate: 55% pickrate: 4%)Viper
* Viper's Poison Attack and
Viper Strike that can slow Razor, and is one of the few heroes that can keep him immobile.
* Altogether, Viper's skills reduce Razor's attack speed, heavily reducing the benefit of the damage drain from Static Link.
Additional:
* Storm Surge is counteracted by Nethertoxin, leaving Razor without faster MS.
* Static Link's damage drain doesn't bother Viper a lot as most of his early to mid game damage is magical.
Enchantress
[wiki] rating: -0.6 (winrate: 40% pickrate: 1%)Viper
* Heroes with break can disable Untouchable for a while: Doom and
Shadow Demon (via
Aghanim's Scepter),
Viper
Kunkka
[wiki] rating: -0.6 (winrate: 44% pickrate: 4%)Viper
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
Chen
[wiki] rating: -0.6 (winrate: 46% pickrate: 0%)Viper
* Hand of God has a long cooldown, so damage over time spells can be hazardous for Chen, forcing him to use it prematurely: Jakiro,
Venomancer,
Viper,
Dazzle,
Phoenix.
Silencer
[wiki] rating: -0.6 (winrate: 48% pickrate: 7%)Viper
* Heroes with damage-increasing passive abilities, such as Viper and
Riki, will usually kill Silencer in a short time before he even has time to set up his abilities.
Crystal Maiden
[wiki] rating: -0.6 (winrate: 50% pickrate: 14%)Viper
* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz,
Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.
Spirit Breaker
[wiki] rating: -0.6 (winrate: 50% pickrate: 8%)Viper
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer,
Viper,
Dazzle,
Arc Warden
Treant Protector
[wiki] rating: -0.6 (winrate: 51% pickrate: 5%)Viper
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
Troll Warlord
[wiki] rating: -0.6 (winrate: 52% pickrate: 9%)Viper
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
Alchemist
[wiki] rating: -0.6 (winrate: 53% pickrate: 7%)Viper
* Viper can bully Alchemist out of mid lane quite easily, forcing him to either retreat into jungle, or stay harassed in lane, and get very few last hits. Vipers break also completely disables
Greevil's greed which prevents Alchemist to earn his amazing amounts of money.
Zeus
[wiki] rating: -0.4 (winrate: 48% pickrate: 9%)Gyrocopter
* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: Lina,
Lion,
Zeus
Viper
* Corrosive Skin counters Zeus in lane by canceling the effects of
Clarity as Zeus relies on Arc Lightning to farm and secure last hits.
* Corrosive Skin also increases Viper's magic resistance to shrug off Zeus's magical nukes.
* Nethertoxin breaks Static Field.
* Due to Zeus' poor mobility, Viper Strike will cripple Zeus and will allow Viper and his teammates to land a lot of attacks.

About
This website was made to help you in pick stage of online game Dota 2. It calculates rating for each possible counterpicks based on tips from web-based database made up entirely of user contributions Dota 2 wiki.
You will get the list of recommended hero counters with a list of tips written by Dota 2 wiki contributors explaining why it's good against the particular hero. In comparison to other similar websites, which show only rating based on average hero winrate from dotabuff or similar service.
How to interpret this data
Take it with a bit of grain of salt, especially if the recommendation has a low rating (<= 1), some heroes
may win a lane in an early game but would lose in late game (and vice versa). That's why sometimes
you could hero names appearing as a counter and as being countered, as on image:
You can also add your own tips, update old data and fix mistakes by editing page on Dota 2 Wiki (it works like Wikipedia - anyone can contribute, you don't even need to register) these edits will appear on this website automatically (data is updated several times per week).
Right now there is no app/overlay that will detect picks automatically (like overwolf dota plus or become the gamer), instead, you can open web version in a steam in-game browser or use mobile version on your smartphone.
