The mysterious
Marauders attack a mutant named
Tommy and her
Hellfire Club boyfriend in Los Angeles for the purpose of following her back to New York and finding the location of the underground mutant community known as the
Morlocks. The Marauders kill Tommy and hundreds of Morlocks before the
X-Men and
X-Factor teams arrive separately and fight them, avoiding the total slaughter of the Morlocks. The two teams however do not meet during the battle and suffer crippling losses: X-Factor's
Angel is crucified by the Marauders, and
Thor, who help save the horribly wounded Angel and the rest of X-Factor from suffering any additional harm. Thor uses his powers to cleanse the dead from the Morlock tunnels with fire, which causes problems for the X-Men, who briefly believe that the firestorm was caused by the Marauders and believe that the
New Mutants died in said fire. Several Morlocks, including
Berzerker and
Masque, make their way into the surface world and begin to work for their personal aims. Meanwhile,
Wolverine saves the Power Pack
