Tatsunoko vs. Capcom: Ultimate All-Stars updates the original game with several gameplay refinements and new characters. A new online play option lets players challenge players across the world. The original cast returns, except for Hakushon Daimaoh, and is joined by several new characters:
Joe the Condor (Science Ninja Team Gatchaman, a.k.a. Battle of the Planets)
Because the original Tatsunoko vs. Capcom wasn't intended for overseas release, Tatsunoko characters weren't originally picked based on their international rights availability. Almost all the characters were able to be cleared for this sequel, except Hakushon Daimaoh; as a result, he was left out of this game in all regions.
