Sigma Abilities and Ultimate


Brilliant astrophysicist Dr. Siebren de Kuiper's life changed forever when an experiment gone wrong gave him the ability to control gravity; now, Talon manipulates him to their own ends.

De Kuiper was considered a pioneer in his field. His life's work involved devising a way to harness the power of gravity. Equally known for his groundbreaking research and eccentric personality, he conducted most of his studies from his lab in The Hague. Believing that he was close to achieving his goal, he performed his most important experiment on an international space station.

But something went wrong, triggering the brief formation of a black hole. De Kuiper was only exposed to its power for a moment, but he suffered serious psychological damage. The area around him began to experience strange fluctuations in gravity, peaking and dropping in time with his reactions. He had to be evacuated immediately.

Upon returning to Earth, De Kuiper was quarantined in a secret government facility. Between his ravings about the patterns of the universe, the psychic damage he sustained, and the gravitic anomalies happening around him, he was deemed unsafe and detained for years under the name "Subject Sigma." Isolated and unable to control his powers, De Kuiper retreated into his own mind. He thought he would never see the outside world again.

When Talon discovered De Kuiper's existence, they infiltrated the facility and broke him out, planning to use his brilliance and research to further their plans. In their custody, De Kuiper slowly gained control of his powers. Now, gravity moved according to his will, and he was closer than ever to achieving his life's goal. But the same experiment that had opened his mind had also fractured it, and he struggled to keep the pieces together.

De Kuiper continues to develop his powers in hopes of unlocking the secrets of the universe, unaware that Talon is using both him and his research.


The primary fire consists of two orbs Sigma can throw forward as missiles a short distance. The funny thing is these can ricochet once against a wall, ceiling, or the ground to impact enemy players straight on, or hidden out of view. There is no ammo limit. Like, Sigma can shoot unlimited Hyperspheres, with barely half a second cooldown. A tiny pause between two consecutive orb shots happens during the animation where he summons the orbs back to his hand. The Hyperspheres do splash damage, doing more damage to the main target.

Gather a mass of debris and throw it at an enemy to knock them down.



Remember the now-replaced Symmetra ability to throw a barrier forward that moved across the field in a straight line? Sigma does something very similar but he has control on how far that barrier moves forward using the right-button. To stop the barrier from moving forward, simply release the right-button and the barrier will stay still. There seems to be a less than a second cooldown on how often you can summon the barrier back to him. Let's say your shield is down to 800 points. You can still summon and re-summon the Experimental Shield with no cooldown. It will still have the 800 points unless the shield takes further damage. The Experimental Barrier can withstand up to 1500 points of damage. Upon destruction, Sigma can summon a new Experimental Barrier after a 5-second cooldown.

The most important use of Sigma's Experimental Barrier is that this ability makes him a de facto Pharah counter. Let me explain. Pharah deploys her Ultimate. Pharah is unable to move or cancel her Missile Barrage. That means, Sigma can deploy his Experimental Barrier as close to Pharah in the air as possible... causing Pharah to kill herself, as the missiles' damage on the barrier will be deflected back at her.

Hold to propel a floating barrier; release to stop. Press again to recall the barrier to you.



When you hold your side-button and cast Kinetic Grasp, any enemy damage sent your way will be absorbed to create a temporary shield that protects you and your team behind. This shield lasts for 3 seconds, and it has a 15 second cooldown. Let's say a friendly Reinhardt in your team keeps walking toward a Orisa + Bastion comp. His shield goes down. Sigma can deploy his Experimental Barrier which has a 1500 points right after. As soon as Sigma's barrier is destroyed, Sigma can immediately cast a Kinetic Grasp to absorb incoming damage for 3 seconds. This 2-tank combo might be enough to close in on the enemy Orisa + Bastion to disrupt them. Sigma can walk forward while Kinetic Grasp lasts.

Absorb projectiles in front of you and convert them into shields.



Originally, Doomfist was supposed to grab a rock and throw it at an enemy. The Overwatch team found the ideal hero to do just that. Using his gravitic powers, Sigma pulls the ground to form a large boulder and hurls it toward a target. Any enemy players near the main target get splash damage and knockback. This ability is ideal against McCree, Reaper, Genji, Mei, and Doomfist. I wonder if Accretion can interrupt Ultimates. Hmm...

Another awesome use for Accretion is that Sigma can boop players backward off a cliff. Now this ability would have been even more awesome if Sigma could replace the debris boulder with anything: such as a car, lamppost, or any of the loose props in every map. Like crushing the object into the shape of a boulder and throw it. That would have been rad.

Gather a mass of debris and throw it at an enemy to knock them down.



This Ultimate is very powerful. It has about the same range width as Doomfist, probably bigger. Sigma levitates high above the ground to allow him to see the battlefield while a giant circle target is drawn on the ground as a guide. Any enemy caught when Sigma presses the button will be caught in a gravitic flux that catapults enemy players high into the air for 2-3 seconds, then they drop to the ground causing fall damage. Seems the higher Sigma floats while channeling the enemies are catapulted upwards the same distance. The higher up, higher the fall damage? Would be nice to experiment that further. Combined with Zarya's graviton surge -- enemy players remain high in the air longer. This ultimate will be devastating to bunker comps.

Manipulate gravity to lift enemies into the air and slam them back down.



Overall, Sigma feels like a solid tank with a very unique abilities kit compared to other tanks. He has two types of barriers, he can knockback enemies, and he has a terrifying ultimate similar to Zarya, but it actually does fall damage — while playing a creepy music in the background. It is the new High Noon on the block. Hear the creepy music? Run.
