7. X-51, the Machine Man
(Machine Man/Nextwave, Marvel Comics)
Aaron Stack!! X-51! The Machine Man!
The only one of 51 experimental robots that didn’t go insane and turn murderous, X-51 first popped up in Marvel's 2001 A Space Odyssey comics. Remember how I said those old Godzilla comics were in continuity? Yeah, ALL of the licensed comics used to be (other than Star Wars, sadly).
Aaron made a name for himself fighting alongside the Hulk, Alpha Flight, and the Fantastic Four. He also had the misfortune of running into Tony Stark while he was in his "angry psycho drunk" phase. Aaron was able to save some people from Stark drunk driving his Iron Man suit. Later, he was infected with Sentinel tech and spent some time fighting the X-Men.
In the modern era, he spent some time working for Nextwave before going off to kill alternate dimensional zombies. He returned, and was most recently seen working as part of Domino’s Mercs for Money team.
