This is a concept drawing for a character in the upcoming AD Police Classified Files comics I intend to draw at some point.
This character is an homage to ~Bubblegumdove
This is a character known as Danin Stone, in his 20's.
Danin works for the AD Police and takes the role of heavy support, as seen in his heavy armour variant of the standard uniform (This is based on 95% an unused concept from the BGC series) and is armed with an experimental railgun that he often likes to lord over the others as some sort of mark of superiority.
Danin is... misunderstood. He is a man's man, living by his own rules and following his own laws accordingly. Despite his macho attitude, he is a pretty cowardly man - sometimes giving the impression of a limited intellect, though it doesn't seem to interfere with his duties within the AD Police.
His unit ident is the number 10, and he refers to himself as a "Perfect Ten" for many different things.
Despite how he acts, he is not the team leader.
His personal icon is a cheeseburger, though the reason for this has not been revealed.
