Keldeo doesn't evolve and doesn't have a pre-evolved form
Keldeo appears to be a Unicorn. It's white with blue hair around its chest/neck and tail, and has red hair on its head.
Keldeo is genderless.
The mane, tail and horn are all longer on Keldeo's Resolute Forme than that of its Ordinary Forme. Additionally, the horn takes on a shape different than that of the horn of Keldeo's Ordinary Forme.
Keldeo has been released as part of an In-Life event in Japan, and promotional downloads at a certain retailer in North America, Europe and Australia. When taken to Oath Forest in Black 2 and White 2, it can learn the move Secret Sword; with this move in its moveset it will transform into its Resolute Forme.

Trading Card Game
Keldeo is part of the Battle Strength Deck Keldeo and National Beginning Set.
Keldeo has not made an appearance in the Anime.
Keldeo appears in the 15th film Kyurem VS The Sacred Swordsmen.
Keldeo's Manga Information is unknown as of writing.
Keldeo is in the Overused (OU) tier of competitive battling as a top-tier offensive threat. Due to a nice base 108 Speed, wallbreaking capabilities with Secret Sword and Hydro Pump, and ability to wear down its checks with Scald burns, Keldeo is a Pokémon that can give opposing teams lots of trouble. Keldeo's typing allows it to check some very threatening Pokémon like Mega Gyarados, Bisharp, and Heatran. Its best sets are an all-out attacking set with either Life Orb or Choice Specs, a Substitute + Calm Mind set, a Choice Scarf set, and a RestTalk set that acts as a consistent offensive check to Dark-types. Keldeo's primary flaws are its lack of coverage options which can lead to it getting walled by a good chunk of Pokémon that resist its STABs and the fact that there are still a good chunk of Pokémon that are capable of outspeeding Keldeo such as Latios, Mega Metagross, and Tornadus-T.
Keldeo cannot breed.
