That is a final boss, not the final boss! The robot formerly known as Vengeance: www.deviantart.com/professorfa… gets an upgrade too.
He's a bit of a tough one to colour since his armour is supposed to be gold but hopefully you get the idea. One thing I always tried to do with this character was give him a 'manic' look on his face. It always seemed to be a struggle, but this eye design seems to work for it.
As an ungraded version of Replay, it would have been easy to give him some sort of super-powerful, high definition video gun, but I didn't want to dilute Replay's unique features if I could help it.*
His gun does take the rough idea of the Shuttershot one step further, but with a different execution. There is a reason why the gun is shaped like a dragon, but it's based in the character design history, rather than an in-universe reason.
Finally his emblem. In the past Vengeance had a sickle shaped emblem. It was meant to be reminiscent of a scythe, but the sickle shape worked better as an icon. When he became Rereplay: www.deviantart.com/professorfa… it became a moon (linking it to Replay's star) but now that the star is also gone, I had to come up with something else. This one here has two meanings. On one hand it's a pitchfork, making the sinister demon connection, on the other hand it's a crown, making the superiority connection.
*It's something that narks me in fiction - iterating on a character so many times that the original starts to look boring by comparison (ie: Mario, Metaknight)
