Origins[]

Years ago, the time-traveling Sentinel Nimrod traveled back in time to kill mutant leader Charles Xavier years before he could found his X-Men. Nimrod was defeated and destroyed, but a part of it managed to infect a university janitor.^[1][2]

The janitor went on to have a child named Sebastion Gilberti. Sebastion was born with the ability to communicate with machines. Sebastion struggled with being different and the burden his powers and Nimrod's influence placed on his young mind. Believing that Sebastion was a mutant, Charles Xavier sought him out when he was starting his X-Men, but Sebastion's mother rejected Xavier's offer due to her dislike of mutants.^[2][3] However, she would go on to lie to Sebastion, telling him that she had begged Xavier to take him in, but he had refused.^[4]

Many years later, when the Sentinel Master Mold was destroyed by the X-Men, it uploaded itself into Sebastion, creating a new being; Bastion.^[2]

Operation: Zero Tolerance[]

Allying himself with Mister Sinister, Bastion secretly orchestrated the Mutant Massacre on Genosha by the Wild Sentinels. He kidnapped Magneto, who was presumed killed in the attack, and kept him imprisoned by fitting him with an Inhibitor Collar. When Henry Gyrich almost exposed him to Rogue, he arrived on his apartment and killed him on his sleep.^[5]

Bastion planned to destroy mutantkind by using his Sentinel technology to upgrade humanity, creating so-called Prime Sentinels, a mix of human and machine, just like he himself.^[2] As he unleashed his Prime Sentinels upon mutantkind, destroying the X-Mansion, he was betrayed by Valerie Cooper, who freed the captive Magneto. Magneto traveled to the North Pole and used his magnetic powers to unleash a global EMP, disabling the Prime Sentinels.^[2]

• Cybernetic Body: As a synthetic life form he possesses various superhuman attributes:
  • Reanimation
    • Sentinel Creation
  • Technopathy: Bastion has the ability to communicate with and control machines.^[2]
  • Portal Creation^[2]
  • Enhanced Durability: As part machine, Bastion can survive in extraterrestrial environments, such as the vacuum of space or on the Moon.
    • Regeneration: Bastion can efficiently self-repair, however, his repair does have is limits as he wasn't capable of fully regenerating after Jubilee blasted him in the face. His self-repair is not as powerful as Nimrod's.
  • Flight: Bastion can normally levitate using jet boosters, but after absorbing Cable's mechanic arm, he was able to grow a pair of metallic wings, similar to those of Archangel. He is fast enough to fly all the way up to Asteroid M.
  • Energy Projection: Bastion can fire purple energy beams and blasts out of his chest, hands, and even his mouth. They are powerful enough to incap mutants as well as match Cyclops' optic blasts.
  • Teleportation: Bastion can teleport mid fight like when Rogue tried to attack him.

• Bastion was voiced by Theo James as an adult, and by Kari Wahlgren as a child.
