Keldeo left the Swords of Justice to prove itself worthy and earn its own legends. Some occultists think Keldeo taught Unovans how to partner with Pokémon instead of fighting them. Even if the timeline doesn’t quite match up, the tale gets retold anyway.

Keldeo’s sacred sword is so powerful that it has sliced castles clean in half. It appeared once to save humans, when a ship in the middle of an ocean was attacked by a Gyarados swarm.
