PROTAG

Reason for amnesia: Attacked by Darkrai when they attempted to travel back in time.

Do they get their memory back?: No, they don't recover their memory.

“Fun” facts: - The pokémon incarnated by the protagonist is chosen by a personality test. - The protagonist is supposed to be a human who turned into a pokémon, but we never meet humans in these games. I've always found it strange. - This game traumatized an entire generations of children - including me :)

TOUMA

Reason for amnesia: During an incident at the beginning of the series his memories ended up getting sealed away as the world was being saved.

Do they get their memory back?: Yes. Not too far in the series he gets pieces back.
