IRON SLAB

Iron Slab is an homage to all the characters in shonen battle manga who refuse to fight in ways that make sense. Play through a short tournament arc to flesh out your fighter, write their backstory as you go through flash backs, and grow more powerful every time somebody punches all the blood out of your character's body. 

Iron Slab is a GM based tabletop role-playing system for 2 to 4 players. CW for references to addiction and violence.  Let me know how it goes if you end up playing it!
