Pokemon Black White 10
Keldeo is a Water/Fighting-type Generation V Mythical Pokémon. Keldeo used to live in a forest that burned down in a terrible fire. Cobalion, Terrakion, and Virizion found Keldeo and took it in as their own, making it the fourth, but secret member of the Musketeer Trio. It resembles d'Artagnan in the novel The Three Musketeers by Alexandre Dumas. It has a signature move that is called Secret Sword.
