I've been rewatching the animated Justice League/JLU episodes (and having a great time doing so). Animated Amazo has some pretty incredible feats, including curbstomping a force that included most of the Green Lantern Corps, Orion and Superman, plus Dr. Light, Captain Atom and a whole bunch of other high-level energy projectors. This was after he casually transferred Oa into another dimension because it was in his way, and before he casually trashed a team of JLU members including Wonder Woman, Supergirl and Steel.

Who is the weakest character you can think of who would be able to beat Amazo?
