Not the final product, obviously, but here's what I got so far. History is more or less decided I'm mainly waiting to see what the Light Master character is like before I actually fill it in. The character's bio is slightly dependent on him essentially being found and taken in as a young child by the Light Master.

[hider=Kengo][u][b]Basic Information[/b][/u]
[b]Name:[/b] Kengo
[b]Age:[/b] 18ish (Exact age is unknown)
[b]Gender:[/b] Male
[b]Homeworld:[/b] Not actually known. Considers Old Bastion his home.
[b]Affiliation (light, dark, or other):[/b] Light

[u][b]Physical Information[/b][/u]

[b]Appearance:[/b] A boyish teenager with a carefree expression, Kengo has deep, dark hair with an ever-so-slightly tint of indigo. It's long, though not exceedingly so, and almost always worn in a ponytail of some sort, save for maybe a few stray bangs here and there. His eyes are usually kind and curious in their expression, and pure brown in hue. He stands at an average height, just over five feet tall, and weighs just a bit under a hundred-eighty pounds. His physique, while not overly muscled, is instead well-toned and lends itself well to a more agile and cunning fighter rather than strong and burly.

[b]Casual Attire:[/b] He has a near skin-tight shirt with sleeves that stop just past the elbows. It's mostly dark grey in color, save for a curiously X-shaped area across the chest which is white. Lower down he wears what can only be described as "poofy" trousers, as if the legs of a kimono had been trimmed to just above the ankles and then tightened at the hem, and black, white, and red laceless shoes on his feet. Over that he wears a "coat" of sorts, not really a coat as it has short sleeves and is left opened save for the center, which is kept closed by a leather belt. The coat is white in the middle, and red on the top and bottom, with yellow-gold accents along the hems. The coat also possesses white, decorative fur along the collar. Finishing off the attire is a pair of dark, leather, finger-less gloves on his hands.

[b]Battle Attire:[/b] He doesn't change much from his casual attire, save for the addition of minor armored bits worn over the torso but still underneath the coat. His shoes and trousers are naturally replaced by more armored boots and greaves for protection.

[u][b]Personal Information[/b][/u]

[b]Personality:[/b] Kengo is, for the most part, a kind-hearted kid not afraid to stand up for what he believes in. He despises bullies, and corruption even more so, often letting his kinder nature get the better of him and picking a fight with anyone who victimizes the innocent. There is more to Kengo than this, though, as seen in the very rare occasions where he is truly angered by something. His expression changes from it's usual appearance to one of an ice-cold bloodlust, apparently symbolized by a change in his normally brown eyes, them instead appearing to be a more yellowish-gold. He's also a swift learner, claiming to be able to learn more about his opponents as he continues to fight them until eventually finding their weakness and exploiting it. Such ability is the mark of the potentially brilliant strategist.

[b]History:[/b] Where Kengo originated from is a vast mystery, the simple truth of the matter is that his original home world cannot be determined. Whether this means it fell to Darkness or was swallowed by World Eater, no one really knows. However, the circumstances of his birth are not all that important in the grand scheme of things. Rather, his story truly begins on a cold night some sixteen or seventeen years ago, when Master Lao discovered a baby boy no older than one or two years old among the outskirts of Old Bastion, seemingly abandoned. But the boy himself was not what caught the Master's eye, rather it was the silvery Keyblade the child clutched in his arms like a sort of teddy bear that piqued his interest. Wondering if it was truly possible for child so young to have a strong enough heart to summon a Keyblade, Lao took the boy home hoping to locate his family, but would never find them.

And so he came to raise the boy himself, as well as train him in the way of the Keyblade, giving him the name Kengo. During this time, Lao discovered a gift in the young Kengo, a sharp instinct that allowed the boy to learn as he fought. But there was something else in Kengo the Master had not expected, Darkness that seemed to lurk deep within the boy's heart and pour out in times of great emotional stress. It made the lad a potential danger, the Master knew, but he could not simply abandon him as his previous family presumably did. Instead, Lao devoted Kengo's training to keeping him focused and in control of his feelings, so that whatever Dark powers lurked inside young Kengo's heart could not consume him, or worse.
