Biography

X-Men: The Last Stand

Leech (Jimmy) (Earth-10005)-1-

Leech played a pivotal role as the source of a "cure" for the mutant gene. Magneto planned to kill Jimmy, who was being kept at Alcatraz Island, thus destroying the cure and preserving the mutant species. Magneto and his Brotherhood of Mutants attacked the facility, which was defended by federal troops as well as the X-Men.

Juggernaut was sent to find Jimmy while Kitty Pryde raced to save him. When Pryde discovered that she was unable to phase through walls while near Jimmy, she mocked Juggernaut into charging at them. Juggernaut tried to smash them into the wall. Instead of breaking through, Jimmy's nullifying powers removed his invulnerability and he was knocked unconscious.
