Skullbuster is a member of the Reavers.
Skullbuster helped his teammates to deal with the Morlocks and find a crashed spaceship in their tunnels. Finding the shuttle, the cyborgs then tricked Wolverine and a couple of X-Men down to them and they fought. The ship was accidentally opened and the Spirit Drinker emerged from it, draining the life forces of some of those nearby, including Skullbuster. Once the alien was defeated, Skullbuster and his teammates who were drained, were revived.
