Dragon Ball Z: Broly - The Legendary Super Saiyan
1993

This is the most I've seen Goku act silly in DBZ. Lots of good gags, but sometimes it popped up in supposedly tense moments. Vegeta being stunlocked over Broly's power was so out of character, but I couldn't help laugh at remembering that in TFS.

Broly is shown as a purely evil character here. Makes me appreciate how they fleshed out his character more for his Super counterpart.
