Plotline: Raditz has just arrived on Earth and Goku and
Piccolo are fighting him.Suddenly a time machine appears and quickly explodes! Through the smoke and fire the fighters can see Cell and Mirai (adult)Trunks locked in combat. In the future Cell had ambushed Trunks trying to get into the time machine. During their struggle,one of them hit the control panel changing the coordinates and initiating the blast off!
Upon arriving in this time,Cell realized he could awaken the Androids early in order to get the power he needed to destroy Trunks. So he fights a llittle longer,and performs a taiyoken attack and disappears,quickly traveling to Dr.Gero's lab. Radditz shocked at Cell's power level,throws down his scouter and quickly escapes into the mountains. After realizing that all of their enemies have escaped for the moment Trunks explains his problem to Goku and Piccolo. They quickly agree that the dragonballs should be able to fix time back to normal. Meanwhile Freeza and his warriors hear the conversation and begins heading towards Earth to wish for immortality. On the way he picks up Nappa and Vegeta and summons the Ginue Force(I know it's spelled Ginyu,but that might confuse those from Dex's RPG.) to meet him there. Elsewhere on Earth the magician Babidy's magical eqipment senses all the power soon to be available and begins his plans to ressurect Majin Buu. In the future all the good guys realize that the timeline is messed up quickly travel through time to try and fix things. ( thanks to Trunks for making about 98% of this. I think I was the first to come up with the time machine malifunction...)
