Just while I have it in mind, Willow is a Pokemon Trainer OC that is based off of the fangame Unbound! I will eventually get around to his about page, but the general basis of Willow is that he was recently apart of the criminal organization the Shadows, but was exiled when he refused to participate in a plan that he deemed morally corrupt. Originally he was imprisoned, but with the help of another prisoner (the player character -- in his canon that would be Adair, who belongs to a friend of mine) he was able to escape.
Despite making it out, he lost every single Pokemon that he previously had as a Shadow. As one does at the beginning of a Pokemon game, he was able to pick a starter -- of which he chose Gible.
Now he aims to destroy the organization that sought to kill him, and inevitably, killed his beloved Pokemon.
