Accretion
Harnessing the gravity of black holes to control the battlefield.
In the scientific lexicon of the Overwatch universe, 'Accretion' refers to the gravitational accumulation of mass and energy rather than a specific named ability or weaponized device found in standard hero kits. While fans often associate the term with Sigma due to his mastery over gravity wells, official documentation lists his powers as Gravimetric Blast and Kinetic Grasp instead. This concept appears primarily in lore discussions regarding high-energy physics and astrophysical phenomena that heroes like Sigma manipulate during combat. It represents the theoretical underpinning of how gravitational fields can be weaponized to pull enemies or shield allies, grounding the fantastical elements of the game in pseudo-scientific reality.

Lore & Background
Sigma, a brilliant astrophysicist, lost his mind and body to the gravitational anomalies he studied. In-universe scientists theorize that Sigma does not create gravity but rather bends existing fields, causing objects to accelerate toward a focal point. This phenomenon is distinct from standard kinetic weaponry. While Winston's barrier projects hard light and Moira manipulates biotic energy, Sigma's powers are rooted in the fundamental forces of physics. The term 'Accretion' in lore discussions often highlights how his shields can absorb incoming projectiles, effectively accumulating mass before redirecting it. Despite its prominence in fan theory and scientific analysis within the narrative, the Overwatch command does not classify this as a standalone technology. It remains an intrinsic part of Sigma's mutated physiology, making him a walking singularity capable of altering local gravity to protect his team or crush opposition.
Reader's Guide
While not a button-press ability named Accretion, the mechanics mirror Sigma's Shield Wall and Kinetic Grasp interactions. Players utilize gravitational pull to disrupt enemy positioning or absorb damage. Strategically, understanding this 'accretion' effect helps in predicting where projectiles will be drawn toward during his ultimate or defensive stances. Limitations include range constraints and energy cost; maintaining gravity fields drains Sigma's resources quickly. Lore-wise, there are no upgrades for this concept as it is tied to his biology. However, tactical usage involves funneling enemies into tight spaces before triggering a pull effect, mimicking the mass accumulation of an accretion disk.
