Ogun, Kitty Pryde’s dead ninja teacher who keeps running around as a ghost, invades S.H.I.E.L.D.’s Helicarrier. I mean, why not? Everyone else does! (See the tag below.)
What makes this a little different is that Ogun invades in the form of a computer virus.
After jumping around and possessing SHIELD agents, Kitty finally exorcises Ogun and has the opportunity to kill him (kill a ghost), but shows mercy.
This leads Ogun to introspection.
Wolverine plays a big part (of course), and it’s shown that he and Nick Fury worked together in the ’60s as part of the National Security Agency, where they also worked with Carol Danvers.
