DOA: Dead or Alive
(2006)

In this video game adaptation into a movie, it turns out that: there is no money prize to be won, the championship has been organized by Donovan (Eric Roberts) in order to get his nanobots inside the bodies of the fighters, so that he can use the information he collects to forecast his opponents' gestures and to beat them.

He also detains Kasumi's lost brother against whom he wins a fight, once stronger with all of the girl's "stolen" abilities.

Weatherby, in love with Helena, turn against Donovan and triggers the complex destruction.

Donovan cannot withstand the combined assault of everybody and dies on his Island.

Everybody else survives. The girls land at Kasumi's place, about to defend themselves from Kasumi's former army (she was banned when she left to find her brother).

Thanks Mirko!
