Hi, 35Baragon, welcome to Dragon Ball Wiki! Thanks for your edit to the File:DRAGONBALL Z 19-137.jpg page.
Hey there! Thanks for asking permission about fanon on the DBZA wiki. The wiki you're referring to is currently inactive, so I don't see much point in making anything over there, honestly. I'm pretty sure the Ultra Dragon Ball Wiki is used for fanon sometimes, but you'd have to look into it. I'm not sure how active the community is over there as I've never been a member of that wiki. I'm only an admin on the TFS wiki, but while that wiki in itself is fanmade, I'm not entirely sure what the creator's regulations on fanon posts are. I would ask, but he's been inactive for years. Sorry for the inconvenience!
