Alright folks, this is where we get some stuff together and decide who the deadliest is.
Putting together intelligence, powers, and skills, who do you think is the deadliest being in the Marvel Universe? (Cosmics such as Galactus and his heralds are not included although there are beings that can handle them without being cosmics)
I put my money on Thanos. The Mad Titan has outsmarted Marvel's most intelligent beings and swats Marvel's heaviest hitters away with no effort. He's also incredibly fast for a big guy. He's definitly number 1 in my book.
