Gaslight

You're a superhero. Super Strength. Super Durability. Your enemy is Gaslight, a supervillain with no world-ending weapon, cosmic artifact or army of monsters. They don't need them. Gaslight can lie so convincingly, manipulate so skillfully, and weaponize emotion so effectively that even the strongest minds can begin doubting their own memories, beliefs, motives, and perceptions. Heroes retire. Teams fracture. Friends become enemies. Cities turn against their protectors. Nobody knows whether Gaslight possesses a genuine superhuman ability or is simply the most dangerous manipulator alive. Now they're focused on you.
