Hidden in the files of the game's arcade version is an unused character named Blodia, a reference to the giant robot piloted by Jeff Perkins in Capcom's Armored Warriors and Jin Saotome in the spin-off game Cyberbots: Fullmetal Madness. The character is unfinished, sharing its moveset with Gamof. Unusually, instead of looking like the Blodia, its appearance is that of a MS-09R Rick Dom from the 1979 anime "Mobile Suit Gundam".

During the sixth episode of Destructoid's Bit Transmission podcast, Capcom's former senior manager of community Seth Killian stated that the project was originally meant to be a Star Wars game. However, Capcom wasn't able to obtain the Star Wars license, so they scrapped the idea and turned the game into it's own IP.
