Dragon Ball Z
An evil little Namek-jin, Garlic Jr., is gathering all of the Dragon Balls
together to wish for immortality. Since young Gohan has the #4 Ball sewn to
his cap, Gohan is kidnapped by Garlic's minions. This causes Gokuu to seek
out Garlic (whose mansion is located on a black island to the south of Kame
House). Garlic also wants to get rid of Kami-sama, so his minions attempt to
kill Piccolo (if Piccolo dies, Kami-sama also dies, and vice versa.) So
Kami-sama and Piccolo join in the battle, as does Kuririn. The minions are
wasted, but Garlic, Jr. already made his wish, so he is unkillable. Garlic
and Kami-sama fight it out, and Garlic wins (he wants to get rid of
Kami-sama to make way for his own "reign of blood", but he doesn't kill
Kami-sama right away.)
Garlic, Jr. gets beaten up a bit by Gokuu and Piccolo, so he decides to
create a "Dead Zone" (a black hole) which threatens to suck everyone in and
kill them. But Gohan (who had eaten a hallucinagenic apple, and is still
feeling a bit of a buzz) gets angry, and blasts Garlic into the Dead Zone.
The Dead Zone closes, sticking Garlic into a form of eternal hell.
