DemonDragonNinja's Lair

12-year-old Ace Ripley is an average boy from the town of Del Juevo, living in a world where robots are a way of life for many and having them clash in stadiums is common entertainment (something he dreams of becoming a champion in someday). However, Ace's life changes when he and his best friend Sloane Plunderman discover his family's big secret — a cave hidden in his basement containing a meteor emitting unusual radiation from it.
