==Doctor Octopus==
:  Otto Octavius
:: Founded fifth Masters of Evil: Guardians of the Galaxy 28
:: Doctor Octopus is a criminal mastermind who can mentally control his metal tentacles, which were fused to his body in an industrial accident that left him criminally insane. He is a longtime recurring adversary of Spider-Man, though he has fought other heroes such as Hawkeye, Iron Man, the Avengers and Mister Fantastic as well. He founded the fifth Masters of Evil to help him loot Avengers headquarters of its scientific resources while the Avengers were otherwise engaged during the Infinity War; however, his Masters were thwarted by the Avengers support staff and the visiting Guardians of the Galaxy, forcing Octopus to flee when his own disgruntled confederates turned against him.
