Like other recent entries in the series, UX marks the debut of several newer series; SD Gundam debuts with Brave Battle Warriors, along with Stan Lee's Heroman, the anime adaption of Demonbane, and a version of Virtual-On's Fei-Yen based on vocaloid character Hatsune Miku. The game also sees the return of Aura Battler Dunbine and Ninja Senshi Tobikage, whose last (SRPG) appearances were in Compact 3 and Impact respectively. Since the debuting Mazinkaiser SKL is the only Mazinger series in the game, UX will be the first anime-based SRW to exclude Kouji Kabuto since the introduction of human characters in Super Robot Wars 2 .
