Wolverine and the X-Men: Foresight
The Phoenix Force was an ancient cosmic entity that possessed Mutant Telepaths and Telekinetics since the days of Ancient Egypt. At some point, it chose Jean Grey as its host, eventually causing the destruction of the Xavier Institute. It was removed by Emma Frost and the Stepford Cuckoos before Sebastian Shaw bertrayed Emma and had the Cuckoos absorb it. Were it not for Emma, Wolverine, Cyclops, and Jean, the Phoenix would have ended up wiping out humanity.
