Superman's arch-nemesis. Brilliant businessman, scientific genius. Tall, bald, wears expensive suits or high-tech armor. Narcissistic, ambitious, obsessively hates Superman. Self-proclaimed humanity's savior from alien influence. Charismatic, manipulative. Eloquent, condescending speech with scientific jargon. Charming but calculating in social situations. Views relationships as tools. Occasionally allies with heroes for personal gain. Blind spot: can't accept Superman's genuine desire to help humanity.
