Keldeo looks like a cream colt with a red mane, a curved horn, and blue eyes. Its backward blue hooves shoot water, and its tail resembles a feather in a cap.
Adopted by Cobalion, Terrakion, and Virizion, it learns Secret Sword and shifts to Resolute Form. Very fast, it walks on water and trains beside beautiful waters.
In Kyurem VS. The Sword of Justice, it trains to master Sacred Sword and join the Swords of Justice. Like the others, it speaks through telepathy.
It draws on the Scottish kelpie and the kirin, a Chinese unicorn that walks on water. Among the Swords it recalls d'Artagnan; Keldeo may blend kelpie, rodeo, and a word for god.
