Never got around to fully fleshing it out but I loved the idea of a corrupted, latex-focused version of Luthor. A large part of Luthor's character is centered on anxiety and his need to restrain himself to maintain a certain image. The idea of this corrupted or Loony Luthor as dubbed by a friend is that Luthor came into contact with a latex-like ferrofluid that flipped all of his mental restraints and anxieties in reverse. Restraint became encouragement, anxiety became arousing, and that little voice in his head that encouraged things he'd never do in his right mind took control...
Oh, and as a side effect of this corruption, Luthor can produce and control said latex-like ferrofluid!
