5 best Overwatch 2 heroes to duo with Sigma 

Sigma in Overwatch 2 is one of the strongest tank characters in the game in terms of damage mitigation. This hero, like Reinhardt, can use a shield ability to block incoming projectiles. The shield has a health pool of its own and can be destroyed. However, this shield does not remain with Sigma as it needs to be projected and stationed at a place. This makes it possible for Sigma to block attacks from one direction while freely moving around to participate in team fights.

Sigma in Overwatch 2 has a devastating set of abilities, including an ultimate that can eliminate weakened enemies with a single cast. This makes his ultimate one of the biggest tactical advantages your team can secure before heading into a full-blown fight for the objective. However, Sigma cannot regenerate and needs a constant stream of healing to sustain on the battlefield. This makes it impossible for this character to flank, as he needs to stay with the main team and provide protection.

This article will highlight the most effective characters you can pick to duo with Sigma in Overwatch 2.

5 best Overwatch 2 heroes to duo with Sigma: Bastion, Ashe, and more

Talon’s eccentric astrophysicist and one of Overwatch’s best additions, Sigma, is a great pick as a solo Tank in Overwatch 2. His versatility on the battlefield makes him a formidable opponent.

Gravitic Flux, Sigma’s ultimate, demonstrates his terrifying power. He can fly and lift enemies in a certain target radius and slam them on the ground, chipping 50% of their health away. When paired right, it makes for one of the scariest ultimates to go against.

On that note, here are the five best Overwatch 2 heroes to duo with Sigma:

1) Bastion

When the eccentric astrophysicist and the meep-morp robot pull up together in Overwatch 2, it is pretty much curtains for the enemy team. Bastion and Sigma have a great synergy together. With Experimental Barrier being mobile and deployable, Sigma can place it in front of Bastion to protect him when he reconfigures into his Assault form. Being one of the strongest Damage heroes in the game, this duo can dominate when played tactfully.

Another strong combination is their ultimates, Gravitic Flux, and Configuration: Artillery. Anyone caught in Gravitic Flux with a well-timed combination of Bastion’s ultimate can be eliminated in a jiffy.

2) Ashe

Ashe's kit flourishes when her tank can create space for her. With her Viper, she can deal enormous amounts of damage and is often the solo carry in the game. To do that, Ashe needs to have that space to engage in mid-long-range combat. Sigma’s presence and his aggressive abilities can facilitate that.

With Hyperspheres and Accretion, Sigma can demand a lot of attention and have control over the tempo of the battlefield in Overwatch 2. This allows Ashe and her expert marksmanship to demolish enemies from a distance. Ashe can use her ultimate, B.O.B., to quickly eliminate any target Sigma lifts with his Gravitic Flux. They’re terrifying as a duo, but only with proper communication.

3) Symmetra

Symmetra is a great Damage hero to pair with Sigma. Her light-bending Photon Projector does immense damage from the right range. Sigma, having no mobility of his own in Overwatch 2, benefits greatly from having Symmetra on the team.

Her Teleportation pads provide the former with a great tool to reposition and maraud forward with her. Furthermore, her ability to dispatch the Photon Barrier acts as a great shield for the team, it also allows Sigma to recall his own shield and let it regenerate.

4) Widowmaker

Being a mid-range tank whilst having Experimental Barrier in his arsenal allows Sigma to create a lot of opportunities for Widowmaker to shine. The latter's devastating sniper is great for headshots, an ability that is further accentuated by the cover offered by Sigma's barrier.

Sigma’s ultimate allows Widowmaker to eliminate multiple targets as they’re suspended in the air. The combination of Gravitic Flux and Widow’s Kiss is a splendid proposition, as it could easily turn the tides of any game in your favor.

5) Ana

Overwatch 2’s resident grandma, Ana, is hands down the best support to duo with Sigma. Her Biotic Rifle and Biotic Grenade allow her to be a safe distance away from any fight and yet, provide the necessary support.

While Ana’s healing definitely benefits Sigma, the true potential of this duo is expressed through a combination of their ultimates. Nano-Boost with Sigma’s Gravitic Flux and Hyperspheres make him the Grim Reaper of Overwatch 2. He possesses the capacity to wipe out the entire team alone and with ease.

Sigma in Overwatch 2 bears the load of protecting the entire team from incoming damage while playing a match. You need to communicate with your duos and the team during team fight scenarios to execute proper strategies to maximize your chances of winning. This means that you need to be able to call for attacks and retreats whenever necessary.

Sigma has a bigger health pool than most heroes in the game but can quickly be eliminated if targeted by the enemy team. This is why it is crucial to time your abilities to ensure it is not wasted. Placing your shield correctly will also help the damage dealer in your team take more space on the map.
