"Angel... Azazel... Emma... Banshee. Mutant brothers and sisters, all dead!"
Erik Lehnsherr[src]

During a violent and aggressive confrontation between Charles Xavier and Erik Lehnsherr on a plane, Erik reproaches over the death of Azazel, Angel, Emma Frost and Banshee.

But Sean's autopsy file was not seen by Mystique, implying that Sean may still be alive and that he is likely in hiding, thus, he was not among the other mutants that were experimented on by Bolivar Trask, as Erik only presumes that he is dead.

X2: X-Men United[]

Sean's name appears on a list of names Mystique scrolls through on Stryker's computer while looking for Magneto's file.
