Good point, Mizrael.
I remember reading that the meteor-collision only reversed some of his powers.
It is interesting that Pre Crisis Bizarro took a knock to the head for that to happen, and the much-maligned Byrne posited a psionic aspect to Kryptonian super-powers. It's like the super-brain got scrambled in some regards so the powers got reversed. It also jibes with Red K effects which can cause just about anything to happen to powered Kryptonians.
In Moore's "Whatever Happened to the Man of Tomorrow?" tale, Bizarro decides to become a better 'imperfect duplicate' by being better reversed. Superman doesn't kill so Bizarro became a mass murderer. Superman is alive so Bizarro killed himself with Blue K.
The only problem I had with Moore's story is it failed on so many levels if you were really into the Superman mythos. Take Bizarro World for example, Earth-1 had a JLA so the Bizarros heroes instead of being loners (the opposite of Earth) form a Bizarro JLA.
Similary in Superman #379 (Jan 1983) Bizarro Batman comments that if there was a real crisis then he would team up with Bizarro just like Batman and Superman do. But by the Bizarro code this shouldn't happen because Bizarros are supposed to do the
opposite of Earth people. Also in this issue we are reminded that Bizarro Lex Luthor is a hero but the problem is he is a brilliant scientist just like his Earth counterpart when by the Bizarro code he should be an total idiot.
The Bizarro dictionary also was similarly illogical - sometimes a word would mean the opposite of its earth definition, other times it would look like a 3rd grader's guess at a definition and other times the defintion seemed to have a logic all its own. Like Tulip would mean what you speek with (two lips) and Yesterday would mean the day after tomorrow.
Then you get to Myyzptlk himself and everything goes out the window. Prevous issues like Superman V1 #335 had firmly established Zrfff culture as going aorudn practical jokes so why this nonsense about choosing how he is behaving? More in Superman V1 #421 (Imp-TV) points out his homocidal cousin Nzykmulk is only 42 Joljos (their year) older than he is and yet is far more powerful than Mxyzptlk. But if Mxyzptlk is immortal and been good for 1000 year as a prankster for another 1000 than 42 Joljos difference not is going to matter.
Yes 'Whatever Happened to the Man of Tomorrow?' is a fun read but from a continuity standpoint it has major problems.
