History
The green-skinned Leech was orphaned as a toddler. His parents left him to die when his mutations became apparent. He was found by the Morlock Caliban and taken to a woman named Annalee who raised him and several other young mutant orphans as her children. During his life in the Morlock tunnels, he made friends with a mutant his age named Artie Maddicks and had a few brief encounters with the X-Men.
During the "Mutant Massacre," Mr. Sinister rallied his henchmen, the Marauders, to infiltrate the sewers and massacre all the Morlocks living there in an effort to rid the world of "genetically impure" mutants. While many Morlocks were killed, Leech, Artie and Caliban survived, rescued by the Power Pack and the X-Terminators (the X-Factor in their mutant roles). read more
