My Idea: Random Story Events
How it works: Every once in awhile some character from the Story pops up and the server can either continue their lives or try to team up to beat this character.
(Optional)Why it's good: Pretty cool and adds to the thriller of the game like "I hope Frieza isn't trying to blow up Namek right now. I can either fight and die like a man, or hurry and get on the spaceship"
