Monstro the Octopus is a gigantic octopus that first appeared in Tales of Suspense #8 and was created by Stan Lee and Jack Kirby.
Not much is known about Monstro the Octopus other than the fact that it was suspected of being an octopus that was mutated through atomic weaponry. Following Monstro the Octopus' attack on a Soviet coastal town, Professor Mark Faraday was called in by the Soviet Diplomats to investigate Monstro the Octopus. Upon guessing the theory of its origins, Professor Mark Faraday was able to get it shrunken back down to its normal height in 24 hours.[50]
