Possessing Polaris
Shortly after the Mutant Massacre ended, members of the Marauder attacked the home shared by Lorna Dane (Polaris) and Alex Summers, a.k.a. Havok. However, Havok was in New York City, leaving Lorna Dane alone to defend against the assassins. Malice possessed Polaris, and soon learned that she was trapped within this host, unable to escape Dane's body. It was later insinuated that Malice's power was connected to the earth's electromagnetic field. After possessing Polaris, Malice became the field leader of the Marauders, leading the team during the all-out demonic invasion on New York City known as Inferno. The team was defeated by the combined efforts of the X-teams, and Mister Sinister was apparently killed by Havok's brother, Cyclops.

Soon after, Zaladane sent her allies, the Savage Land Mutates, to abduct Polaris and bring her to the Savage Land. Zaladane claimed to be Lorna's long-lost sister, and stripped Polaris of her mutant magnetic powers and inadvertently replacing them with a different power set. This process resulted in Malice being expelled from Lorna Dane's psyche.
