H/P Doomsday makes it to Round 5 without breaking a sweat.

Vulcan.

Personally I think Doomsday has the strongest punch on that list.

Doomsday killed Superman.

Killer Croc is having trouble beating Bane.

Justice Leagues' Watchtower definitely. It's incredible.

@rbt: No offense but I honestly don't see none of them one-shotting KO Hulk.

Maybe someone like Imperiex can do something like that, but it's debatable.

Onslaught is my favorite.

@logy5000: Personally for me they seem the best since he blitzes other speedsters. However, I'm sure others also have great blitzes.

This type of mentality makes people hate Batman and it's fans.

Zoom by far.
