Wildcat (Christoph Nord / David North / Maverick / “Morse”) First Appearance: X-Men (2nd series) #5
First Involved: Wolverine (2nd series) #50 (Wildcat), #62 (identified)
Notes: In one memory implant scenario, American federal agents codenamed Wolverine, Sabretooth and Mastodon raided a revolutionary cell in Windsor, Ontario made up of Silver Fox, Andre (the Professor), Carlisle (John Wraith) and Morse. Because all other players were Weapon X subjects or staff, one would assume Morse was as well. By process of elimination, it's likely but unconfirmed that "Morse" was played by David North.
-Similarly, Maverick's Weapon X codename is also implied but unconfirmed. North is a known Weapon X test subject and target for Shiva's termination parameters. All other animal codenames on the parameters' list except "Wildcat" are accounted for, indicating that North was known as Wildcat.
Feral (The Native) First Appearance: Wolverine (3rd series) #13
Last Appearance: Wolverine (3rd series) #19
Notes: For unknown reasons, the test subject codenamed "Feral" did not appear on Shiva's termination parameters. She also did not appear to have any memory implants or other augmentations, so it's possible the Native escaped before her mental engrams could be uploaded into the Shiva program.
