A thought ocurred to me today and I was hoping someone might be able to answer this.
Seeing as how Bizarro is Superman's polar opposite, I can understand the heat breath, freeze vision, and the fact that he's a villain rather than a hero. But If the sun acts as Superman's source of energy, would it not then act as a DE-energizer for Bizarro?
Likewise, would Kryptonite not boost Bizarro's power rather than weaken him like it does Superman?
Is there any proof of this Pre or Post Crisis? Maybe I'm looking into this way too much but I find this very perplexing.
