Naoto Date

Tiger Mask, whose real name was Naoto Date, was a feared heel wrestler in America who was extremely vicious in the ring. However, he became a face (a "good-guy" wrestler) after returning to Japan when a young boy said that he wanted to be a villain like Tiger Mask when he grew up. The boy resided in an orphanage, the same one that Tiger Mask grew up in during his childhood. Feeling that he did not want the boy to idolize a villain, Tiger was inspired to be a heroic wrestler.
