Actually not entire, but it sounds cooler if I said it. Don't worry, I don't use secondary characters in DBZ.
The rule is that we use only the strongest form (as shown in image) of the character, so Goku SSJ1, SSJ2, SSJ3, and SSJ4 can't be together in this battle! More example? Kid Buu and Fat Buu can't be used together as well. Fusion dude such as Gogeta, if used then you can't have Vegeta and Goku! In another word - use only one form of a character without duplicating them.
DC: Post-crisis version and feats only > Characters at their peak (DC One Million Not Allowed) > All members of JLA that ever exist (List) or just use image to make your life easier
DBZ: Manga feats allowed > Characters at their strongest form as shown in 2 images > All characters in both image
This battle is all out, no prep and no BFR, fight is on Warworld have fun!
If any form in either JLA or DBZ can solo another, tell me and I'll impose exception on that guy unless I don't think he or she can solo.
