King of Fighters XIII with the Cell Saga androids from Dragon Ball Z! Yes."
Well, it turns out that's not what this is. Instead, King of Fighters Android is King of Fighters game for Google's Android OS, which is probably a more reasonable business decision in the long run. Judging from the screenshots below, it appears to be based on King of Fighters XIII, or at least heavily influenced by its art style. The game features 20 fighters, five different play modes and unlockable bonus content like trading cards and concept art.
Available now for $4.99, the game is officially compatible with the Galaxy S 2, Galaxy Tab 10.1, Xperia Acro HD, and Xperia Play, which should be a good fit for the title considering it has actual buttons. Compatibility with other Android devices is untested and should be attempted at your own risk; two marketplace reviews already indicate the game does not function on the Galaxy Nexus.
