10 Best Overwatch 2 Heroes To Counter Sigma

Sigma is one of the most versatile tanks in Overwatch 2, known for his strong barrier, crowd control abilities, and high-damage output. His Experimental Barrier allows him to control space effectively, while Kinetic Grasp absorbs incoming damage and converts it into shields, making him difficult to eliminate. His Accretion rock can stun enemies, and his Gravitic Flux ultimate lifts enemies into the air before slamming them down for massive damage. However, despite his strengths, Sigma struggles against heroes who can bypass his barrier, deny his sustain, or pressure him from angles where he can’t effectively defend himself. In this article, we’ll break down the 10 best heroes to counter Sigma, focusing on those who can disrupt his defenses, punish his cooldowns, and prevent him from controlling fights.

#10: Roadhog

Roadhog is a strong counter to Sigma because his Chain Hook can bypass Sigma’s barrier and pull him out of position, forcing him into unfavorable fights. Since Sigma relies on positioning and keeping his barrier between himself and enemies, Roadhog’s ability to displace him makes it difficult for him to maintain control over engagements.

His Scrap Gun deals massive burst damage, allowing him to chunk through Sigma’s health before he can recover with Kinetic Grasp. Even if Sigma tries to absorb damage with Kinetic Grasp, Roadhog can wait it out and hook him the moment it ends, securing an easy elimination.

Additionally, Take a Breather gives Roadhog the sustain needed to outlast Sigma’s damage, and Whole Hog can knock Sigma away, preventing him from using Accretion or setting up his barrier effectively. Since Sigma struggles against heroes who can pull him out of position and deal high burst damage, Roadhog’s hook, sustain, and ability to break his positioning make him a strong counter.

#9: Winston

Winston is a strong counter to Sigma because his mobility allows him to bypass Sigma’s barrier and pressure him directly, making it difficult for Sigma to hold space effectively. Since Sigma relies on his Experimental Barrier to block incoming damage, Winston can simply jump past it and attack him from an angle where he has no defense.

His Tesla Cannon deals consistent damage in an area, meaning that even if Sigma tries to use Kinetic Grasp, Winston’s weapon will still deal damage since it isn’t a projectile. This makes it impossible for Sigma to absorb Winston’s primary fire, forcing him to take the full brunt of the attack.

Additionally, Primal Rage allows Winston to continuously knock Sigma around, preventing him from setting up his barrier or using his abilities effectively. If Sigma tries to use Accretion or Gravitic Flux, Winston’s mobility lets him escape and reposition safely.

Since Sigma struggles against heroes who can dive past his defenses and pressure him directly, Winston’s mobility, sustained damage, and ability to disrupt Sigma’s positioning make him a strong counter.

#8: Junkrat

Junkrat is a strong counter to Sigma because his explosive damage bypasses Sigma’s barrier and forces him to waste cooldowns defensively. Since Sigma relies on his Experimental Barrier to control space, Junkrat’s spam from Frag Launcher can pressure him and his team even when the shield is active.

His Frag Launcher deals heavy splash damage, allowing him to chip away at Sigma’s health and barrier simultaneously. Even if Sigma tries to absorb damage with Kinetic Grasp, Junkrat can simply wait it out and continue pressuring once it ends.

Additionally, Concussion Mine can knock Sigma out of position, preventing him from setting up his defenses or making him an easy target for his team. Steel Trap can also be used to limit Sigma’s movement, making it harder for him to reposition or escape when under pressure.

Since Sigma struggles against heroes who can pressure him from outside his effective range and force him to waste cooldowns, Junkrat’s explosives, crowd control, and high burst damage make him a strong counter.

#7: Echo

Echo is a strong counter to Sigma because her mobility and burst damage allow her to pressure him from angles where he struggles to defend himself. Since Sigma relies on positioning and his Experimental Barrier to block incoming damage, Echo can simply fly over his shield and attack him from above, where he has no protection.

Her Sticky Bombs and Focusing Beam combo is highly effective, as it can quickly burn through Sigma’s health, especially when he drops below half health. Even if Sigma tries to use Kinetic Grasp to absorb damage, Echo can wait it out and continue pressuring him once the ability is on cooldown.

Additionally, Duplicate can be used strategically to copy a high-impact hero, allowing Echo to mirror Sigma’s abilities or take advantage of another tank hero to overpower him. Since Sigma struggles against heroes who can attack from angles where he can’t defend and force him to waste cooldowns, Echo’s aerial advantage, strong burst damage, and ability to bypass his defenses make her a great counter.

#6: Bastion

Bastion is a strong counter to Sigma because his high sustained damage can quickly burn through Sigma’s barrier and overwhelm his defenses. Since Sigma relies on his Experimental Barrier and Kinetic Grasp to mitigate damage, Bastion’s Assault Configuration can force him to drop his shield and struggle to keep up with the incoming firepower.

His Assault Configuration deals massive damage per second, meaning Sigma’s barrier won’t last long under Bastion’s rapid-fire shots. Even if Sigma tries to absorb damage with Kinetic Grasp, Bastion can simply wait it out and then unleash his firepower once Sigma is vulnerable.

Additionally, Bastion’s Tactical Grenade can be used to disrupt Sigma’s positioning, forcing him to move out of cover or interrupt his ability usage. Since Sigma struggles against heroes who can pressure him with overwhelming firepower and break through his defenses quickly, Bastion’s sheer damage output, ability to destroy his shield, and strong positioning make him a great counter.

#5: Pharah

Pharah is a strong counter to Sigma because her aerial mobility allows her to bypass his barrier and attack from angles where he has no defense. Since Sigma relies on his Experimental Barrier to control space and block incoming damage, Pharah can freely rain down rockets from above, forcing him to reposition constantly.

Her Rocket Launcher deals high burst damage, allowing her to chip away at Sigma’s health and pressure his barrier without being affected by Kinetic Grasp. Even if Sigma tries to absorb damage, Pharah can simply wait it out and continue applying pressure once the ability is on cooldown.

Additionally, Concussive Blast can knock Sigma out of position, making it harder for him to maintain his frontline presence or line up his Accretion stun. If Sigma tries to use Gravitic Flux, Pharah can stay airborne and remain unaffected, allowing her to counterattack while his team is vulnerable.

Since Sigma struggles against heroes who can attack from above and avoid his abilities, Pharah’s aerial advantage, explosive damage, and ability to pressure him from outside his effective range make her a strong counter.

#4: Zenyatta

Zenyatta is a strong counter to Sigma because his Orb of Discord significantly increases the damage Sigma takes, making it easier for his team to burn through his barrier and health. Since Sigma relies on his barrier and Kinetic Grasp to sustain fights, Discord Orb weakens his durability, forcing him to play more cautiously.

His Orb of Destruction deals consistent long-range damage, allowing him to pressure Sigma from a safe distance where Sigma struggles to fight back effectively. Even if Sigma tries to use Kinetic Grasp to absorb projectiles, Zenyatta can wait for the cooldown to end and continue dealing damage.

Most importantly, Transcendence is highly effective against Sigma’s Gravitic Flux, as it completely negates the damage-over-time effect, preventing Sigma from securing kills with his ultimate. Since Sigma struggles against heroes who can weaken his sustain and pressure him from long range, Zenyatta’s Discord Orb, high burst potential, and team-wide healing make him a strong counter.

#3: Tracer

Tracer is a strong counter to Sigma because her high mobility allows her to constantly pressure him while staying out of his reach. Since Sigma relies on landing Accretion and using his barrier to control space, Tracer’s quick movement and unpredictable playstyle make it difficult for him to land his abilities.

Her Pulse Pistols deal high burst damage at close range, allowing her to chip away at Sigma’s health and force him to waste Kinetic Grasp defensively. Even if Sigma tries to absorb damage, Tracer can simply reposition and continue applying pressure once the ability is on cooldown.

Additionally, Recall allows Tracer to escape from dangerous situations, preventing Sigma from securing easy eliminations. Pulse Bomb is also highly effective against Sigma, as his large hitbox makes it easy to stick him with the explosive for a quick burst of damage.

Since Sigma struggles against heroes who can dive past his defenses and pressure him up close, Tracer’s speed, burst potential, and ability to evade his attacks make her one of the best counters.

#2: Reaper

Reaper is one of the best counters to Sigma because his high burst damage and lifesteal allow him to quickly break through Sigma’s barrier and sustain himself in fights. Since Sigma relies on his shield and Kinetic Grasp to mitigate damage, Reaper can pressure him up close, forcing him to waste cooldowns and making him vulnerable.

His Hellfire Shotguns deal massive damage at close range, allowing him to shred through Sigma’s large health pool before he can recover. Even if Sigma tries to absorb damage with Kinetic Grasp, Reaper can simply wait for the cooldown to end and continue dealing high burst damage.

Additionally, Wraith Form allows Reaper to escape Accretion and Sigma’s Gravitic Flux, preventing him from being an easy target. Death Blossom is also highly effective against Sigma, as his large hitbox makes him an easy target for the AoE damage, and his barrier cannot block the ultimate.

Since Sigma struggles against heroes who can pressure him up close and out-damage his sustain, Reaper’s lifesteal, close-range burst, and ability to bypass Sigma’s defenses make him one of the strongest counters.

#1: Sombra

Sombra is the best counter to Sigma because her Hack ability completely disables his defensive tools, making him an easy target for elimination. Since Sigma relies on his Experimental Barrier, Kinetic Grasp, and Accretion to control fights and absorb damage, a well-timed Hack removes all of these options, leaving him completely vulnerable.

Her Stealth allows her to flank undetected, getting close enough to disable Sigma before he can react. Even if Sigma tries to reposition or play defensively, Sombra’s constant pressure forces him to waste cooldowns and prevents him from holding space effectively.

Additionally, EMP is devastating against Sigma, as it completely removes his barrier and disables his abilities, making him an easy target for focus fire. If Sigma tries to use Gravitic Flux, a quick Hack or EMP can interrupt it before he can lift enemies, wasting his ultimate.

Since Sigma struggles against heroes who can disable his abilities and force him to play without his defensive tools, Sombra’s Hack, EMP, and ability to track him make her the strongest counter to shut him down in Overwatch 2.

Conclusion

Sigma’s versatile kit, strong barrier, and high-damage output make him a powerful tank, but the right heroes can shut down his defenses, disrupt his abilities, and prevent him from controlling fights. Sombra and Reaper are the best at disabling his abilities and pressuring him at close range, while Tracer and Winston can dive past his barrier and force him to waste cooldowns. Pharah and Echo can attack him from above, where he has no defense, and Zenyatta’s Discord Orb weakens his sustain, making him easier to eliminate. If Sigma is dominating your games, these 10 heroes will help you counter his shield, deny his abilities, and stop him from taking over fights.
