The Dragonball series (and other Toriyama works)

Ah, Dragonball, the series known for a single fight lasting multiples episode, powerups consisting of screaming/hair color changes, and Goku usually being the last fighter standing.

Dr. Slump is sort of canon to the Dragonball series. It is an earlier series that Akira Toriyama worked on... but if you think about it, Goku visited Dr. Slump's Penguin Village both as a kid and an adult with no one in Dr. Slump aging at all. To be honest, any and all anime and manga series that Akira Toriyama has worked on can exist within the same universe, but not the same continuity.

The reason for that is that he reuses designs because he is both usually under a time crunch and is lazy.

But we're here for kisses. Both attractive men and women in his works are quite kissable. Just make sure they're all over 18 years old.
