Goku and Gohan attend a reunion on Roshi’s island, where Goku introduces his son to all of his old friends. The smiles quickly fade, however, as an unexpected visitor - Raditz - lands on the island.

To escape a pack of wild animals, Gohan ventures into an ancient cave, where he meets an old Capsule Corp robot. The robot has lived alone in the cave for over 30 years, and he’s not happy to have visitors!
