2. Arm Fall Off Boy
No, you're not reading that wrong: it really does say "Arm Fall Off Boy." A DC character presumably pitched as a joke to a madman who wanted to ruin the comic book industry forever, Arm Fall Off Boy is described perfectly by his genuinely lame title. After being careless whilst holding an anti-gravity metal called "Element 152" (what is he like?), Arm Fall Off Boy was gifted with the ability to, uh, detach his own arms and use them as blunt weapons. And even in the universe in which he inhabits, Arm Fall Off Boy is considered a kind of running joke: nearly all of his appearances involve him auditioning to join an organisation known as Legion and messing it up every time. What a life!
