Main Character Syndrome (MCU insert with Homelander/Viltrumite powers)

In one universe, the third-rate actor Leo Maxwell died on stage and reincarnated into a Xianxia world (check out my Method Acting story for THAT plot)... ...but in another, he instead slipped on a banana peel and accidentally saved a hero destined for the Truck-kun treatment. (Note -- this is just a little something to help me get through writer's block. Don't take it so seriously!)
