Sorry that there's no color but I finally made a design of undersaint sans.

I might color it in the future.

The things you need to know about saint is that he's younger than most sans' he will do anything for his bro and if you mess with him than you absolutely going to die. He's older than his bro and he's been in lots of fights. Mostly his cuts are from that. One of his cuts on his face is from a fight. The other one he made himself to remember gaster. He's been abused by lots of monsters thats why he has handcuffs all over his body. He has a determined soul. His outer layer is light very light gray. That means he might sinned but it's was for saving somone atleast.

His eyes are very different from others. He has a diamond shape in his right eye and a upside-down heart shape in his left eye.
