Leonardo Convinces Hitler

Hitler's brain was still functioning decades after World War II and power to time machine. The Hitler from the future was destroyed by the turtles while the past Hitler tries to get the brain only to be punched by Raphael. Leonardo convinces Hitler that he is in hell and they are demons that have come for his brains. They told the dictator that they already have his soul. He shoots himself in the head so the turtles can't recover his brain. That's an advanced level maneuver. I mean, they don't call him the world's most fearsome fighting team for nothing, guys. Whoo.
