Pokémon: The First Movie - Mewtwo Strikes Back (1998)

A girl wears a short revealing shirt.

During the massive fight between the original Pokémon and the clones, Misty's Psyduck and the Psyduck clone are shown taking turns slapping each other.

People are burned alive. It's not shown but implied.

In an extended, battle to the end scene, we see characters punching, biting, slapping, and wrestling with each other (none are killed). Some characters are shot with laser beams and electrocuted (a few look charred and make crackling sounds). Two characters shoot each with electric beams then run next to each other, knocking many characters out of their way as they speed by. Dragons breathe fire at characters a few times (one gets charred), a dragon's fire is deflected back onto it (the dragon falls down) and two dragons fight and fly into each other (one is driven into the ground and knocked unconscious).

Several characters are lifted up, thrown on the ground or into walls, chased, charged at and knocked down by other characters.

A machine grabs a boy and a character (both escape, though the character has a hair plucked from it); also, Pokemon are captured in balls and put into a machine. A couple of times, two groups of characters stand chest to chest and look as if they're about to fight.

While crossing the sea during a storm, several people are knocked out of a boat by a large wave and are plunged underwater a few times before reaching the shore.

Mild language in the Japanese version only.

None.

Pokémon fight against their own clones while the song "Brother My Brother" plays.

Ash is turned into stone in one scene, which is a very touching/upsetting scene to some people.

Mewtwo wakes up and slaughters all of the scientists who created him. The killings are all off-screen.
