Blue was a simple pony who has a pretty high intelligence level. He went to Peach Blossom Elementary School located in Neighgasaki. After an incident at Aozora Middle School, he went home to think and realized he was happy without a cutie mark. Years later, he gained his mark. An orb emitting light that represents the passions he has. After he graduated, he started working full time as a baker in the Rift City bakery.
Blue is a member of the Rift City and creates art and streams it and creates speedpaints. When he's not at his tablet drawing, he may be writing a story or script or he may be singing or recording audio. If not at any technological item, he's at band on trombone (which he agrees with joshscorcher that it is the superior instrument) or marching baritone. While he does have autism, he doesn't let it affect who he is.
