Heres the plot
Everyone was living their every-day life when suddently they see a big electrical blue creature.
First it appears in Goku's world and throws a big blast at the ground. It starts shaking and Goku blacks out. Then the creature goes to every world doing the same thing. Then Goku wakes up in a new world full of heroes and villans but he doesnt know who's good and who's bad. The heroes around him are people like Naruto, Sora, Master Chief, etc. There a towns people too. No one knows what happened.
A month passed and they r living their life there while scientists r trying to find a way back to their planet. Their economy is the Dollar ( none of that stuff like zenny because most stories us different money).

The creature: Its huge. Its sort of like electrical or a blue energy with a bit of electricity around it.
Lets call it blue. Example of its power: If its arm gets cut of it regenerates it instantly. It can hit, throw blasts, and do a bunch of other stuff.

Rules:
1. No killing other players characters with out their permission.
2. No taking over other players characters without player's permission (original player most inform me first).
3. It may contain explicit language but try to keep it on the low.
4. Its for all ages but dont turn it into a sex story.
5. If a person is incative over 10 days with no reason he/she will be replaced unless he/she isn't in the middle of an important scene.
6. If a person that is important in the scence hold up the story for over two days with no excuse he/she will
be removed.
Pick ur characters and have fun. ;)
