Heroman - 18

Orphaned American boy Joey lives with his grandmother, working at a restaurant in the West Coast city of Centre City (Sentā Shiti, based in Los Angeles) while attending school. Upon hearing of a new toy, a robot called the Heybo, Joey believes that getting one will improve his life, turning him into a hero to protect his friends and family. However, he cannot afford to buy it on his meager salary. His luck changes when he picks up a broken-down Heybo abandoned by a school bully. He tries to fix it, naming it Heroman, but has no luck getting it to work. However, when it gets struck by a bolt of strange lightning, it transforms into a giant robot just in time to save its friend Lina from impending danger. Now, Joey and Heroman are Earth's only defense against the evil insectoid “Skrugg” (Sukuraggu) aliens, unknowingly summoned to Earth by Joey's science teacher.
