"Piccolo, how did you get here?" Son Goku asked.
Piccolo replied, "Earth is in crisis right now. The two Android 17s have merged, and Vegeta and the others are no match for them. You're trapped in Hell and can't get back. If I didn't come to help you, were you planning to stay here for the rest of your life?"
"And that King Yemma has no sense of the bigger picture at all. A single word from him could have helped you get back, but instead he kept babbling on about the rules of Hell. Back in my day, if he had dared to refuse me, neither Heaven nor Hell could have contained my fury."
