When Subject X's people annexed 'Earth-616' (really known as Earth-92272), they were able to permanently bend Wolverine's legs so that he could never walk again.
A year of pushing later, they arrived at an old, abandoned trap with no one and nothing left to finish them off. Out of food and with no where to turn, Armor killed Beast and Wolverine before slowly waiting to starve to death herself.
Powers and Abilities
Once the Adamantium of his legs was bent, he became paralyzed and needed a wheelchair to move.
