Bizarro am bad character depending on what artist isnt writing him. The backwards speaking, opposite figure to Superman whos either a failed clone of the Man Of Steel or one of many inhabitants of an entirely backwards cuboid planet, depending on the continuity, is actually a cool character when somebody actually understands him. Having a craggy-faced, cracked mirror image of Superman who wears a dark, ill-fitting set of tights and destroys everything instead of saving people is a fun, silly Silver Age idea. Its not one that really expands to other DC superheroes, except as a really disappointingly hacky, half-arsed device. So of course theres been loads of other Bizarros! Created when the original Bizarro attempted to clone The Flash, Bizarro-Flash originally had a mallet symbol, but thats since been replaced by a thunderbolt-shaped mustard stain. Hes a clumsy oaf who moves really slowly. The fattest man alive. The opposite of The Flash, see? Providing grist for exactly zero interesting milled stories, hes long since been confined to the rubbish heap.
