As the rules say, so long as their is a notable difference, the profile should be allowed. And Xeno Goku has plenty of legitimate powers. Since when has the concept of HP be contested to mean Life force or Life points or hit points or health? I mean, it might be iffy for a game like this-- but at worse, the "player" in this case, kind of like the summoner in Yugioh, takes the damage that the characters being used take-- meaning that WITH this worse interpretation of the system, it means that those with God Ki can give Life energy to the main summoner/player. Or something. Though, this assumes there's another person/a summoner in the first place. It's more likely to just be energy draining for themselves.
Someone get SSJRYU please. Matt, I will give you that some of the abilities here are more for Xenoverse Goku or another version of Goku than Xeno Goku, which is different. So how about this. Let's make a Composite VIDEOGAME Goku. Then, he would have everything demonstrated by the other Goku's above. Including space time Manipulation, both SS4 and SSG/Blue, scaling from Demigra, etc. So that way we get Xenoverse Goku and Xeno Goku and all the other Goku's in one profile without having to make it so that everyone won't ask for specific profiles and shit. Composite Game Goku would only have Dragon Ball game stuff, and since the Goku from Xenoverse referenced the movies, he would have Non-canon abilities too, so...
