Bane's 
Fiend's Grip.
Mars
* 
Dragon Slave deals reliable magic damage during the laning phase against Mars.
* Lina's 
Eul's Scepter of Divinity and

Aghanim's Scepter.
Omniknight

Tidehunter
[wiki] rating: 1.0 (winrate: 54% pickrate: 9%)Bane

* Enfeeble only reduces distance of 
Gush, but not of 
Anchor Smash or 
Ravage, and thanks again to Kraken Shell, is easily dispellable for him in team fights.

[wiki] rating: 1.0 (winrate: 50% pickrate: 3%)Bane
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use

Phantom Assassin, 
Terrorblade, 
Troll Warlord, 
Drow Ranger,

Chaos Knight, 
Sven, 
Wraith King, 
Bounty Hunter, 
Alchemist, 
Templar Assassin, 
Nyx Assassin, Bane.
Mars
* 
Firestorm and 
Pit of Malice are very disruptive in team fights, completely matching Mars especially since it can all be cast inside Arena Of Blood and also does percentage-based magical damage, negating Bulwark.
* Dark Rift can save any allies of Underlord trapped in Arena Of Blood.
* 
Atrophy Aura allows Underlord to lane against Mars quite well since he does not have the best base damage during the early game.
* Underlord is a common carrier of both 
Pipe of Insight and 
Mekansm/
Guardian Greaves, allowing his team to combat Mars in the mid to late game.
Bane
* 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,

[wiki] rating: 1.0 (winrate: 50% pickrate: 28%)Bane

Axe
[wiki] rating: 1.0 (winrate: 48% pickrate: 10%)Mars
* 
Berserker's Call forces Mars to face in the direction choosen.
* 
Counter Helix is a much stronger lane trader than Spear of Mars.
Ogre Magi
[wiki] rating: 1.0 (winrate: 47% pickrate: 11%)Mars
* Mars has no way to trade with Ogre Magi in the early game thanks to his high base health, resistance and 
Ignite.
* Once Ogre Magi gets level 2 he may also have 
Bloodlust, which makes him even harder to deal with in lane.
* 
Fireblast can be ridiculously strong later on in the game for controlling Mars.
* Spear of Mars, which is Mars' main source of damage in the early game, cannot guarantee kills early on Ogre Magi.
Rubick
[wiki] rating: 1.0 (winrate: 47% pickrate: 22%)Bane
* Fiend's Grip is a powerful but channeled ability, making it useful and easy to 
Spell Steal and interrupt with 
Telekinesis.
* Stolen Fiend's Grip or Nightmare combined with 
Arcane Supremacy allows Rubick to disable Bane's allies for a longer period of time.
* As a natural Aghanim's Scepter carrier, Rubick can steal an upgraded Fiend's Grip and deal lots of damage to Bane's allies.

Shadow Shaman, Invoker, Disruptor and Kunkka.
Lifestealer
[wiki] rating: 0.4 (winrate: 50% pickrate: 9%)Mars
* 
Rage, acting as a pseudo-Black King Bar, completely negates Mars' initiation if used in time.

Juggernaut,

Additional:
* Fiend's Grip can disable Lifestealer through Rage.
Zeus
[wiki] rating: 0.4 (winrate: 50% pickrate: 16%)Mars

Storm Spirit
[wiki] rating: 0.4 (winrate: 47% pickrate: 4%)Mars
* Storm Spirit's abilities all do magical damage, which can bypass Bulwark.
* 
Ball Lightning can escape through Arena of Blood and it is easy to dodge 
Spear of Mars.
Additional:
* Ball Lightning makes it almost impossible to catch Storm Spirit without someone else initiating for you.
* 
Overload is not reduced by Bulwark and the magical damage spam can wear down Mars quickly.
Bane
* Wraith King, Medusa, 
Storm Spirit and other mana dependent heroes will have diminished impact on a fight if they survive Fiend's Grip due to its mana steal.
Necrophos
[wiki] rating: 0.4 (winrate: 46% pickrate: 6%)Mars
* Necrophos' largely magical damage completely ignores Bulwark.
* 
Ghost Shroud protects Necrophos from God's Rebuke but more importantly stops Mars from being a threat in lane.

Phantom Assassin
[wiki] rating: -2.0 (winrate: 45% pickrate: 14%)Bane

* Nightmare and Fiend's Grip can ground Phantom Assassin, who normally blinks around with 
Phantom Strike, and stop her from outputting damage, even with Black King Bar.

Mars
* Phantom Assassin's high physical damage is greatly reduced by Bulwark.
* God's Rebuke has true strike, ignoring the evasion from 
Blur.
Monkey King
[wiki] rating: -1.6 (winrate: 45% pickrate: 9%)Bane
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void,

Meepo, 
Mirana, 
Monkey King, 
Morphling, Phantom Assassin, Phantom Lancer, 
Riki, Shadow Fiend, 
Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Mars
* Monkey King's natural reliance on trees makes him an exceptionally prime target for Spear of Mars. Should Monkey King use Mischief to disguise himself, it will still hit him, stunning him in the process.
* 
God's Rebuke easily pushes Monkey King out of Wukong's Command.
Weaver
[wiki] rating: -1.6 (winrate: 49% pickrate: 4%)Bane

Mars
* 
Shukuchi cannot help Weaver escape from Arena of Blood, so with vision, Weaver is an easy kill.
* 
Time Lapse will also not save Weaver in a large amount of situations inside Arena of Blood, especially if he's pinned to the walls with Spear of Mars.
* 
The Swarm and 
Geminate Attack is not very useful against a hero that can tank 70% of his main damage source.

Additional:
* Fiend's Grip pierces spell immunity, rendering 
Blade Fury nearly useless.
Mars
* Bulwark mitigates 
Omnislash which deals physical damage, severely reducing its damage.
* Omnislash switch to opposite direction with each slash, so Mars can easily reduce most of its damage.
* However because {Ability ID:Blade Fury|Juggernaut} gives spell immunity Juggernaut can easily escape from {Ability ID:Arena Of Blood|Mars}.
Additional:
* Juggernaut deals mostly physical damage, which is easily mitigated with Bulwark.
* Juggernaut's Omnislash switches to opposite directions which each slash, so Mars can mitigate most of its damage since he only takes full damage from one direction: his back.

Medusa
[wiki] rating: -1.4 (winrate: 47% pickrate: 2%)Mars
* Medusa's 
Stone Gaze forces Mars to choose between getting petrified, or turning his vulnerable back on Medusa.
Bane
* 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.
Mars
* 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.

[wiki] rating: -1.0 (winrate: 46% pickrate: 4%)Bane
* Heroes with illusions and summons can swarm Bane, who has no area abilities: Broodmother, Chaos Knight, Nature's Prophet, Phantom Lancer, Terrorblade.
Additional:
* One of Terrorblade's illusions can be used to absorb damage and disable Nightmare.
* Terrorblade's large amount of illusions can make it difficult to pinpoint and target the real Terrorblade with Fiend's Grip. But bear in mind that Bane can counter this with 
Aghanim's Shard upgraded 
Brain Sap and by farming 
Mjollnir, although it can be hard to play Bane as carry and farm Mjollnir on him.
* However, bear in mind that illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, and that can make it easy for Bane to detect real Terrorblade unless Terrorblade buys 
Manta Style.

* Spear of Mars and God's Rebuke can push Bloodseeker from Ruptured targets.
Spectre
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Mars
* Spectre cannot have a good game if she is pressured heavily in lane, which is something Mars can do.
* Spectre can use 
Haunt and 
Spectral Dagger inside and outside from Arena of Blood, but it doesn't really matter since Mars does best during the early and mid game.
* Should Spectre get to the late game, Mars can block a large amount of her damage and split the teamfights in his advantage.
Brewmaster
[wiki] rating: -1.0 (winrate: 53% pickrate: 2%)Bane
* After Brewmaster has committed Thunder Clap and Cinder Brew to gank, Bane can use Nightmare on Brewmaster to wait out the debuffs, and might even turn the tables by buying time for allied reinforcements.
* Bane can also prevent Brewmaster from using Primal Split with his long disables.
Legion Commander
[wiki] rating: -0.8 (winrate: 51% pickrate: 13%)Bane
* Heroes with strong dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight.
Mars
* Legion Commander is both good and bad vs Mars, on the plus side she can dispel Spear of Mars with 
Press the Attack and is a good 
Silver Edge carrier. However, Mars is not an ideal 
Duel target, as Bulwark will force her to 1: Buy Silver Edge, and 2: Hit Mars with it before the Duel, allowing a skilled Mars to react, especially with Eul's Scepter of Divinity. In teamfights, Mars will happily draw attention after using his abilities, and tank the Duel with all spells on cooldown.
Bane
* Bane has powerful single-target abilities that can help his allies win Duels, or at least cripple Legion Commander for the duration.
* Nightmare can waste Duel's entire duration as the dueled units transfer the Nightmare back and forth. This may be prevented if a non-Dueling unit attacks the Nightmared Dueler.
Additional:
* Enfeeble, Nightmare and Fiend's Grip all prevent Legion Commander from winning Duels, especially when Bane has 
Blink Dagger.
Mars
* Because Duel requires both combatants to face each other, Bulwark's effectiveness will be increased by a huge margin, which makes it much more difficult for Legion Commander to win any duels against him.
* Spear of Mars and God's Rebuke pushes Legion Commander away during Duels against allies.
Additional:
* Bulwark prevents Legion Commander from gaining wins with Duel.

* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Wraith King
[wiki] rating: -0.6 (winrate: 46% pickrate: 4%)Bane
* Wraith King, Medusa, Storm Spirit and other mana dependent heroes will have diminished impact on a fight if they survive Fiend's Grip due to its mana steal.

[wiki] rating: -0.6 (winrate: 46% pickrate: 7%)Bane

Techies
[wiki] rating: -0.6 (winrate: 47% pickrate: 7%)Mars

Dragon Knight, Mars, 
Centaur Warrunner.

* Heroes with illusions and summons can swarm Bane, who has no area abilities: Broodmother, Chaos Knight, Nature's Prophet, Phantom Lancer, Terrorblade.
Bane
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Mars
* Heroes who lack burst damage will have a hard time against Mars: Phantom Lancer, Nature's Prophet, Lich.
Slark
[wiki] rating: -0.6 (winrate: 52% pickrate: 14%)Bane
* 
Dark Pact can dispel Enfeeble, as well as Nightmare and Fiend's Grip if timed correctly.
* 
Shadow Dance protects Slark from Bane's single-target abilities.
Bane
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Mars
* Bulwark blocks much of Slark's basic attack damage, even during Shadow Dance.
* Slark finds it very difficult to have a good early/mid game when pressured in the early game by Spear of Mars and God's Rebuke.
* Spear of Mars and God's Rebuke can hit Slark through Shadow Dance.
* Should 
Pounce be on cooldown, Slark is very vulnerable inside Arena of Blood.
Silencer
[wiki] rating: -0.6 (winrate: 54% pickrate: 15%)Bane
* Heroes that can disable or silence Silencer for a long time, such as Bane and Legion Commander, can lock down Silencer while their allies put him down.
Timbersaw
[wiki] rating: -0.4 (winrate: 45% pickrate: 4%)Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Bane
* Brain Sap's pure damage ignores stacks of Reactive Armor.
* Nightmare prevents Timbersaw from using Timber Chain, setting him up for chain stuns and burst damage.
* Enfeeble highly reduces regeneration granted by reactive armor.
* Fiend's Grip immobilizes Timbersaw and drains his low mana pool, preventing escape afterwards. It also pierces Black King Bar.
* Bane's multiple disables often force Timbersaw or his teammates to spend gold on a Linken's Sphere.
Ursa
[wiki] rating: -0.4 (winrate: 52% pickrate: 11%)Mars
* 
Ursa is a special mention because despite Bulwark diminishing most of the damage Ursa does, he is quite durable, especially with 
Enrage, discouraging the aggressive all-in playstyle of Mars; Ursa can simply not target Mars.
Bane
* Bane can use Nightmare and Fiend's Grip to lock down Ursa early game and in team fights, forcing Ursa to buy a Black King Bar and making him very vulnerable to being kited once his Black King Bar is down to 6 seconds.
* Overall, Bane's potent disables force Ursa to build more defensive items and play more defensively in general.
Luna
[wiki] rating: -0.2 (winrate: 50% pickrate: 4%)Bane
* Though Bane's Enfeeble can weaken Luna's physical damage output, it still does not weaken her magical damage output.
* Without Black King Bar, Luna's 
Lucent Beam and 0.25 Eclipse Mini-stun talent for 
Eclipse can be used to disable Bane while he is channeling Fiend's Grip.
* Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Mini-stun can repetively stun Bane, and prevent him from even trying to use Fiend's Grip.
Additional:
* It is almost impossible for Bane to use Fiend's Grip properly against Luna's allies due to the huge cast range of the Lucent Beam.
Bane
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Drow Ranger, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Riki
[wiki] rating: -0.2 (winrate: 55% pickrate: 6%)Mars
* Bulwark is generally irrelevant against Riki as he primarily deals bonus damage from behind.
Additional:
* 
Blink Strike gives bonus backstab damage. Along with 
Tricks of the Trade it completely bypasses Bulwark.
Bane
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Mars
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Nature's Prophet
[wiki] rating: 0.0 (winrate: 44% pickrate: 4%)Bane
* Heroes with illusions and summons can swarm Bane, who has no area abilities: Broodmother, Chaos Knight, Nature's Prophet, Phantom Lancer, Terrorblade.
Mars
* Heroes who lack burst damage will have a hard time against Mars: Phantom Lancer, Nature's Prophet, Lich.
Viper
[wiki] rating: 0.0 (winrate: 47% pickrate: 4%)Mars
* 
Nethertoxin disables 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.
* Beware that 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.
Additional:
* 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.
Bane
* Enfeeble weakens Viper's attack damage, any healing he receives and his cast range, which makes him unable to harass enemy heroes with Nethertoxin, Poison Attack and Viper Strike.
* Viper's Corrosive Skin is useless against Bane as all of his damaging abilities deal Pure damage.
* Viper has no solutions to cancel Fiend's Grip and in addition, he hates buying disabling items like Eul's Scepter of Divinity.
Invoker
[wiki] rating: 0.0 (winrate: 48% pickrate: 15%)Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Bane
* 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, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.
Shadow Fiend
[wiki] rating: 0.0 (winrate: 49% pickrate: 23%)Mars
* If Mars lanes middle, Shadow Fiend can keep the lane pushed against him.
* Shadow Fiend can go an entirely magical based build, which is very effective against Mars.
Bane
* Enfeeble can be used to decrease Shadow Fiend's already abysmal level one damage even further, preventing him from getting farm and Necromastery stacks.
* Brain Sap allows Bane to heavily harass Shadow Fiend.
* Nightmare allows Bane to set up some early ganks onto Shadow Fiend.
* Fiend's Grip enables Bane to completely take Shadow Fiend out of a fight and potentially even kill him, even through Black King Bar.
Additional:

Faceless Void
[wiki] rating: 0.0 (winrate: 49% pickrate: 11%)Mars
* Time Dilation while Spear of Mars and God's Rebuke are on cooldown will make these abilities unusable for a long time, rendering Mars nearly useless.
* Mars cannot turn inside the Chronosphere, which makes it easy to attack him from the back, bypassing Bulwark completely.
Additional:
* 
Time Walk allows Faceless Void to escape or enter Arena Of Blood, and helps him recover from Mars' burst damage.
* 
Time Lock's magical damage ignores Bulwark.
* 
Chronosphere allows Faceless Void to reposition behind Mars, ignoring his Bulwark while he is helplessly frozen in time.
Bane
* If Bane is outside Chronosphere, he can use Nightmare or Fiend's Grip to cripple Faceless Void inside.
* Nightmare and Fiend's Grip are long duration disables and can render Time Walk's mobility very unreliable.
Mirana
[wiki] rating: 0.0 (winrate: 52% pickrate: 15%)Bane
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Bane
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Enigma
[wiki] rating: 0.0 (winrate: 52% pickrate: 6%)Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Bane
* 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, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.
Bane
* Heroes with hiding abilities can protect disabled allies:
Outworld Destroyer, 
Shadow Demon, 
Tusk, 
Phoenix with 
Aghanim's Scepter.
Fiend's Grip if he is not the target.
Additional:
* Bane has low mobility and health, making him an easy target for Walrus PUNCH!
* Walrus PUNCH! can be used to cancel
Mars
*
Snowball can protect Tusk and his teammates from a Spear of Mars stun after an Arena of Blood, and with proper targeting, even bring them out of the Arena. This is especially noticeable in the earlier stages of the game before allies buy 
Black King Bar and rely on this less. Even during the late-game, Tusk can purchase a 
Blink Dagger to save allies that are caught before Black King Bars can be used by Blinking in and Snowballing out. 
Tag Team is a constant threat to Mars in-lane, as even with early Bulwark points it deal so much damage and slow that Mars is forced to back off from the lane and play defensively every time the spell is used. 
Ice Shards can be detrimental to Tusk's own team by creating terrain that Spear of Mars can latch on, though using it conservatively is a good enough solution in most cases.
*
* Worth noting is that
