King Cold has very little history or media. Despite King Vegeta being rarely seen, we do know quite a bit about him. His rise to power was the end of the tuffles.

I want to see Mr. Popo's origins, we could get so much more lore on the Afterlife.

None of them honestly. I want a DBS continuation, a movie, or a new series after Super.

Mr. Popo Or King Cold, But as Shadow Said, I would rather have DBS Come Back, or something related to it.

Bardock's ahh didn't rise to anything lol
