While I am not starting exactly yet I am going to just make my disclaimer and reserving the space now.
Disclaimer: I do not own the characters in this fanfic, all credit goes to the respected owners of the characters.(Which is Akira Toriyama or DC comics respectively)
Era for DBZ: Cell Games Era
Era for DC: A combination of JLU and the comics(I am kinda scaling power here to make it work)
Characters in DBZ used(Mains): Goku,Vegeta,Gohan,Trunks, and Cell
Characters in DC used(Mains): Superman, Wonder Woman, Martian Manhunter, and Darkseid
Minor characters used(DBZ): Krillin,Piccolo, and Hercule
Minor characters used(DC): Green Lantern, Flash, and Batman
Setting: Earth Z(DBZ universe)
So this is the basic outline for what's going to be in it as far as that goes, expect the first chapter within the next day or so. Depends on how busy I am.
