History
Scalphunter, Prism, Riptide, and Vertigo were the Marauders, a team of superpowered mercenaries working for Mr. Sinister. They were fighting the X-Men when the Power Pack was attracted to the fight and tried to help the X-Men, but only ended up getting in the way and the Marauders defeated the X-Men.
Later, the Marauders captured Cyclops, who had stayed behind to investigate the matter further, and took him to Sinister's laboratory. Power Pack interfere again and this time, with Cyclops help, they were able to defeat the Marauders. Before the other X-Men cold arrive however, Sinister teleported himself and the Marauders away to an unknown destination.[1]
