Japanese: バトルサーチャー (Battle Searcher)
An item that is used to re-battle Pokémon Trainers the player character has fought previously.
It looks like a triangular wireless mouse.
- In FRLG, the Vs Seeker is found at the strap of Red's backpack and Green's messenger bag.
- In HGSS and in SSBB, Red's character design is the same as in FRLG, including the Vs Seeker. (even though the item is not usable in these games)
