Rem-Ram was a member of the Acolytes. When Fabian Cortez ordered an attack on Xavier´s mansion Rem-Ram was assigned to enter Rogue's dreams, allowing her to touch a man without absorbing his thoughts and feelings. In fact, she had touched Magneto – and even accepted a diamond ring from him – before being jarred out of her sleep by Gambit. When Fabian Cortez forced Rem-Ram to invade a conscious Professor X's mind, Rem-Ram failed. Fabian fled, leaving Rem-Ram and the remaining Acolytes on the grounds of the estate to seek asylum from the X-Men, Professor X refused them.
Rem-Ram was killed after the Wild Sentinels' attack on Genosha. He was among several of the Acolytes' whose bodies were reanimated by the Collective. However, he was later resurrected by the Transmode virus from Selene, along with some other Acolytes.
