Ep. 20: Taken by Surprise!! Son Goku's Attacked By a Metal Storm

Goku and Rilldo continue to fight, but Rilldo reveals his secret power: he can manipulate all of the metal on the planet, allowing him to appear anywhere there is metal, among other things. Pan, meanwhile, is trying to sneak into the main tower, but the emergency removal system keeps spitting her back out. But with the help of another robot, she deactivates the system. Before she can destroy Giru, he reactivates it, spitting her back out. Luckily, the Dragon Balls got spit out with her. General Rilldo tells Goku to give up, because as long as there is metal on the planet's surface, he can't be destroyed. (Source: Wikipedia)
