Based off he long-running series of Mysterious Dungeon games by Chunsoft, this multi-title release (Red Rescue Force for the GBA, Blue Rescue Force for the DS) is an adventure game with semi-turnbased exploration of dungeons featuring characters from the Pokemon universe. It's up to the Rescue Force (Red in the GBA version, Blue in the DS version) to save Pokemon who've found themselves in trouble. While one of your goals is to figure out what exactly turned you into a Pokemon, you've also got to help Pokemon as part of the Rescue Force. You start off serving your duties with your original partner Pokemon at your side, but as you progress, more Pokemon join the Rescue Force and become selectable.
