- Colossus: Blackmailed into joining.
- Magneto: The leader of the group.
- Quicksilver: Magneto's son, in command of the Brotherhood.
Sometime after his failure with Asteroid M Magneto formed a group of mutants who were more powerful than the Brotherhood. He blackmailed Colossus into joining through his sister. They fought the X-Men and Brotherhood, who had joined forces under the deception of Mystique in the disguise of Charles Xavier. They fought and defeated the Sentinel.
Magneto then got Gambit to offer the Brotherhood a place on the team if they rescued Quicksilver from a military transport. The Brotherhood was successful but Quicksilver was placed in command of the team to determine if they were ready for the Acolytes.
Magneto later recruited Mastermind to change the memories of Scarlet Witch so that she loved her father. Toad was initially opposed to the idea, as he had a crush on her, but Quicksilver pointed out that she would stop hunting Magneto and stay near him.
The Acolytes later joined with the Brotherhood and X-Men to stop the release of Apocalypse. However, all teams failed.
They later disbanded when Magneto apparently died. Colossus went back to his native Russia while Sabretooth and Gambit disappeared to places unknown, separately of course.
Xavier read Apocalypse's mind and saw a vision of the future where Colossus joined the X-Men. Quicksilver and Scarlet Witch returned to their father's side.
