Survival Tobita is a Japanese wrestler that achieved a minor cult following by wrestling aliens and monsters (re: people in terrible costumes). He always got destroyed with like, one punch, and then would talk about how he'd try harder next time as people awkwardly left. He released a shirt which you can see below. I made a game based on it. I would say it's probably the best ever TTRPG for one player based almost entirely on t shirt text. It's only one page, please enjoy!
