Pokeman Heroes
Latios and Latias
(2002)

Annie and Oakley take control of Alto Mare's defense system, but accidentally create a tsunami that will surely destroy the city as well as destroying the Soul Dew.

Latios sacrifices himself to stop the gigantic wave, creating a new Soul Dew. As Ash is leaving the city, Bianca arrives and kisses him (it is not revealed if she was really Bianca or Latias in disguise).

Annie and Oakley are sent to prison, where they quickly begin planning their next caper.

Thanks Mark I!
