Bastion is a Defense Hero in Overwatch and RP character used by X Jay's Wing X.


Once a frontline combatant in the devastating Omnic Crisis, this curious Bastion unit now explores the world, fascinated by nature but wary of a fearful humanity. Though "Bastion" appears to be gentle — even harmless, at times — its core combat programming takes over when the unit senses danger, utilizing its entire arsenal to eliminate anything it perceives as a threat. This has led to instances of conflict with the few humans it has encountered, and has driven it to avoid populated areas in favor of the wild, uncharted regions of the world.


Originally created for peacekeeping purposes, Bastion robot units possessed the unique ability to rapidly reconfigure themselves into an assault-cannon mode. But during the Omnic Crisis, they were turned against their human makers, forming the bulk of the omnics' rebel army. Following the resolution of the crisis, nearly all of them were destroyed or disassembled. To this day, Bastion units still symbolize the horrors of the conflict.

One unique Bastion unit, severely damaged in the final battles of the war, was left forgotten for over a decade. It lay dormant, exposed to the elements and rusting while nature slowly reclaimed it. Overgrown with vines and roots and nested upon by small animals, the robot sat inert, seemingly unaware of the passing of time. That was until one fateful day, when it unexpectedly reactivated. With its combat programming all but lost, it instead displayed an intense curiosity about the natural world and its inhabitants. This inquisitive Bastion unit set out to explore its surroundings and discover its purpose on a war-ravaged planet.


  • Bastion's main form is Recon Mode. In Recon mode, Bastion is fully mobile, outfitted with a submachine gun that fires steady bursts of bullets at medium range.
  • Bastion can reconfigure itself into Sentry Mode. In Sentry mode, Bastion is a stationary powerhouse gaining, gaining massive armor bonuses and equipped with a Gatling Gun capable of unleashing a hail of bullets. The gun's aim can be "walked" across multiple targets, dealing devastating damage at short to medium range.
  • Bastion can stop to restore its health; it cannot move or fire weapons while the repair process is in effect.
  • If in danger, Bastion can reconfigure itself to its ultimate mode: Tank. In Tank mode, Bastion extends wheeled treads and a powerful long-range cannon. The cannon’s explosive shells demolish targets in a wide blast radius, but Bastion can only remain in this mode for a limited time.


  • Bastion's love for birds might be a reference to the manga Dragon Ball Z. The character C-16 is a disfunctioning combat android whose murderous instinct was overwritten by a love of nature, especially birds.
