His cutie make expresses his burning serious personality. That with the fact he's one of the fastest ponies in Equestria (right next to Rainbow Dash)But he chooses not to show it off. He's also part of the Ponyville Fire Squad.
He's tends to be a bit of a loner, never really talks much especially if he's not called upon. Absolutely no sense of humor, his face always expressionless. He's a good colt, even if he doesn't look it, he can also be a bit of a softy.
He has dreamed of being one of the best fliers in Equestria when he was young. He soon felt it as a bit childish and gave up on that dream. He then decided he should be a good citizen and works full time at the Ponyville Fire Department. Responding as quick as a flash to any disaster.
