Keldeo

#LegendsDiscovered: KELDEO
"Long ago, a fire started in the Moor of Icirrus because of a war among people. In this fire, Keldeo was separated from its parents, but together, Cobalion, Terrakion, and Virizion took care of Keldeo. They acted as its parents, and they taught it knowledge and moves for survival.
It dashes across the world, seeking more opportunities to further its training. They say that Keldeo must survive harsh battles and fully develop the horn on its forehead before this Pokémon's true power will awaken. Keldeo eventually grew and even surpassed the three Pokémon. In its Resolute Form, the power that lay hidden in its body now covers its horn, turning it into a sword that can slice through anything."

After meeting the three Swords of Justice, we went on a search for the one said to be the successor to the group. We finally met Keldeo, hidden in an open field with a giant rock, located near Flocessy Town!
