If we had a "What if" dragon ball series, which scenario would you like to see?

Imagine a series of "What if" episodes, each episode showing the beginning and the end of a scenario (so it could be short and concise).

Which single scenario would you like to see?

I'd like you guys to talk about ONLY one and maybe give a description of how you think it would play out.

Let me start:

"What if Goku had died with the Saiyans in Planet Vegeta?"

I thought we would see an episode showing Master Roshi, Yamcha, Krilin, Tien, Chiaotzu and etc... dealing with the Red Ribbon Army and Piccolo Daimaoh in their own, ultimately having to get things done without counting on Goku.

Give me your best shot guys!
