KELDEO.

Keldeo was born in the Moor of Icirrus, within the Unova Region, in a time where the humans were at war with each other. While it seemed that his early years would be calm, at best, this war was what ultimately separated him from his birth parents, when a fire broke out within the swamp caused by the warring humans' actions. The young colt was eventually found and rescued by the Swords of Justice; Virizion, Terrakion, and Cobalion. However, there was no sign of his parents, and searches came up fruitless. Keldeo was left an orphan.After long discussion and debate, the Swords of Justice decided to take in the colt and raise him as their own. They acted as his parents, nurturing him while also teaching him how to survive and defend himself on his own. When Keldeo showed potential as a swordsman and a member of the group, they began to train him more intensely.Under the lessons of Cobalion, Terrakion, and Virizion, Keldeo developed skill in agility, strength, and perserverance. He even came to learn the move Sacred Sword, an attack that was only known by his own mentors. But, despite his prodigious talents, the colt had trouble learning patience and humility. His growing skills fueled his ego; and often when he began to feel that his foster parents' lessons weren't enough, he would take off to challenge the wild pokemon in they places they travelled to.Neither did Keldeo seem as interested in helping pokemon for the sake of good deeds; he wanted to become legendary like his mentors. He often did his duties without humility or modesty; he fought for the glory and the attention, not yet practicing chivalry like the rest of the swordsmen. His hubris would eventually get the best of him during another devastating fire.
It was during this particular fire that Keldeo had failed to follow orders, and instead focused moreso on battling the flames than assisting pokemon who were in need of help. It was during this particular event that Virizion became injured from a fallen tree. The young colt finally rushed to her aid, abandoning his efforts, and managed to lead her to safety alongside Terrakion and Cobalion. Some pokemon were not so fortunate that night, and Cobalion pinned much of the blame on Keldeo, particularly for disobeying his orders. Keldeo learned that night that his actions could also do more harm than good, and to this day he still blames himself for Virizion being hurt.From that day forward, Keldeo began to respect others and showed more modesty around his power. Though secretly seeking glory deep down inside, he also sought to become just as righteous and just as his mentors, to make up for his actions and for the lives that were lost in that very fire. And when Keldeo felt he learned as much as he could from his mentors, he ran away—seeking out ways to improve his skills and push himself to the limit in hopes he could become stronger—so that he could overcome more obstacles for the sake of others. For several months, Keldeo went on his own, training to reach his full potential and helping several pokemon along the way.However, he never could have unlocked it on his own. As time went by, Keldeo began to feel homesick, and missed the company of his mentors. After training hard the young colt began his journey in search of the Sacred Swordsmen. It wouldn't be until he came to the Moor of Icirrus, the very place of his birth, that he finally reunited with them once more. Keldeo was welcomed by his caretakers and praised for his merits, and when the time was right, Cobalion, Virizion, and Terrakion helped Keldeo finally unlock his full potential; and learning the move Secret Sword. Along with it, Keldeo gained a new form; his Resolute Form, which he now currently takes.To this day, Keldeo still trains with the Swords of Justice as the youngest member of the group. He travels the world, still seeking to become renowned as one of the greatest members of the quartet—but content to be the young defender of the pokemon race.
