* CrossDressingVoices: [[Creator/MasakoNozawa Goku]], [[Creator/MayumiTanaka Luffy & Luckyman]], [[Creator/JunkoTakeuchi Naruto]], Kenshin[[labelnote:*]]Mayo Suzukaze[[/labelnote]], [[Creator/MiyukiSawashiro Baby Beel]], [[Creator/MotokoKumai Taro]], Tsuna[[labelnote:*]]Yukari Kokubun[[/labelnote]], Reborn[[labelnote:*]]Neeko[[/labelnote]], [[Creator/MegumiHan Gon]] and [[Creator/MariyaIse Killua]].
* DummiedOut: [[http://www.yareyaredaze.com/2014/03/28/j-stars-victory-vs-jotarodiodaiyoh-files-found/ Hackers have found player character name data]] for [[Manga/DragonQuestTheAdventureOfDai Dai]], [[Manga/JojosBizarreAdventure Jotaro Kujo and Dio Brando]] (Whether it is meant to be part 1 or part 3 DIO is currently unknown), as well as [[Manga/ShamanKing Yoh]] among the assist characters.
* MarthDebutedInSmashBros: The localization of this game brought along with it several characters whose respective series were never officially released outside Japan, such as Luckyman, [[Manga/{{Kochikame}} Ryoutsu]], and [[Manga/TheDisastrousLifeOfSaikiK Saiki]]. The most egregious case was that of [[Anime/ChinyukiTaroToYukainaNakamaTachi Tarou Yamada]] -- a character from a series so strange and obscure that it didn't even have a page on the Other Wiki.
* NoDubForYou: The game did not receive any dubs when it was localized and released overseas, likely due to the difficulty of gathering voice actors for all the different series represented in the game.
* NoExportForYou: [[http://www.animenewsnetwork.com/news/2014-12-21/shonen-jump-j-stars-victory-vs-heads-west-on-ps3-ps4-vita/.82495 Averted!]] After months of silence and despite many Jump crossovers before it not getting the localization treatment, ''J-Stars'' received an English release as "J-Stars Victory VS+" in 2015 with added features.
* RoleReprise: All of the characters retain their voice actors from their most recent animated appearance.
* WhatCouldHaveBeen: Incomplete data for [[Manga/JoJosBizarreAdventure Jotaro Kujo, DIO]] and [[Manga/DragonQuestTheAdventureOfDai Dai]] as playable characters, and [[Manga/ShamanKing Yoh Asakura]] as a support character was found within the game disc's assets, suggesting they were planned at one point but DummiedOut later. The three planned playable characters were eventually RefittedForSequel in its successor ''VideoGame/JumpForce''.
