When it comes to the character of Superman, there are a few themes that beat a dead horse...hard. Things like the "Death of Superman" we've seen ad nauseam to the point that we'd even watch Krypton explode again before having to sit and watch a Superman die who hasn't even lived. One of these annoying repeated tropes is the "evil Superman" theme (which is odd as there are evil Kryptonians out there, why people often have to go directly to Superman first before using someone like Zod baffles me), whether it's mind control, red Kryptonite, an alternate universe, or "one bad day" we've seen plenty of instances of rogue Superman. However surely one of these amused you in SOME way.
My favorite was actually from the cartoon Batman the Brave and the Bold, in which they used the trope to a hilarious effect in using some comic covers as scenes. Superman was a real di...fferent person.
What would be your favorite instance of "Superman goes bad"?
