Supporting characters in season 3 onwards of Wolverine and the X-Men.
X-MenEditForge - Forge was present when Jim demanded to go through his father's hardest training level, and he reluctantly did so, hoping Wolverine and Kayla wouldn't suddenly show up. Right after he made the Blackbird spotless, the X-Men had a mission to Egypt to save Emma, and Liger scratched the Blackbird, so Forge wouldn't have to worry about the first scratch. Forge was captured when Weapon X attacked the Mansion, and he was held in a detention area. He's released by Remy, and he follows Scott, telepathically led by Xavier, to the hangar, and they go home. Forge later helped make a virus to destroy the file containing the names of all unregistered Mutants in the USA before they left to invade Weapon X.
MRD/Weapon X/Weapon XIEditSybil Zane - She was put in charge of the robotics and genetics division once Stryker took over the MRD, and she recruited Graydon to be the first in a Sentinel series that replicated human tissue and would use his brain patterns. Graydon agreed after kissing Sybil.
OthersEditHulk/Bruce Banner - Not seen since his last encounter with Wolverine, the Hulk is used as a training system in the Danger Room.
Senetor Robert Kelly - Returned to his office after being captured by Magneto. He put Stryker in charge of the MRD.
Pyro/St. John Allerdyce - Pyro was put in charge of releasing Magneto's prisoners by Scarlet Witch, and after doing so, he was rendered unconscious by Nos.
Scarlet Witch/Wanda Maximoff - After Magneto's banishment, Wanda became the head of Genosha. After having her father's prisoners released, she was brainwashed by Nos into giving him a disc containing the names of all the unregistered mutants in the USA.
