Bizarro (Silver Age)
In the Silver Age, Bizarro was a lot more fun. He wasn't a villain - just a big, misguided goofball who's code of logic would lead to all sorts of wacky hi-jinks. Bizarro had his own girlfriend (Bizarro Lois Lane), and his own planet called Htrae (shaped like a cube instead of a sphere). He even had his own distinct way of talking - Bizarro-speak, where he would say the opposite of what he meant (for example, "Me am smart" would mean "That tree stump over there is smarter than me").
