archangel in the animated series. when he was looking for a way to destroy him. but apocalypse was disquised as a researcher and gave him fake documents.
that was also the introduction and "death" of apocalypses shi'ar ship
which the x-men (beast specifically) coerced into trapping and shooting apocalypse into space in a containment cell...
then archangel flew away.. whee. if you want the episode number i'll find it.. i've got it somewhere.
