draw the character before, I am actually the original creator of the character and the story below is part of its independent background, divorced from Kingdom Hearts.
-----
Most reclaimers live as part of Clans but Nameless is unique in the way that he landed alone as a shooting star on an initially peaceful cartoony-style world.
Not having been fed the correct materials for his armor to correctly grow growing up, his appearance is characteristic, with bits of his golden armor and some bits that look like black naked skin, a result of the accidental malnutrition he suffered from.
In spite of this, Nameless is energetic, enthusiastic, and always willing to help. He also unknowingly suffer from the extreme fear of being alone that all lone reclaimers suffer from, his instincts driving him to get attached to groups as to not be the only one of his kind.
But not all is right with the world he was born in ; despite coming of age, Princess Crystal has not been able to "Name" him, leaving him as "Nameless", unable to determine what his special talent was. Likewise, prophecy speaks of a terrible and ancient evil that is returning to the world.
As a mere assistant and one who was never given a "Name" and thus is not part of any prophecy, Nameless was told to stay home and guard the fort so to speak.
Unknowingly to him, his instinct to fulfill the Eternal Mission of the Dominators is pushing him to disobey and to embark on a journey.
Let's just say that things proceed to go very, very much off the rails at this point. For better or worse? History shall be the ultimate judge of it.
