This sounds fun, so why not, sorry no picture, but here we go. Nightwing is his name, be is a jet black pegasus with a short, blue mane. His cutie mark is an acoustic guitar, he is a street performer, he doesn't have a southern/western accent, his special talent is playing music on a guitar, he is a chill type of pony who will stand up for others (for instance, if a pony is being harassed he will stand up and intervene, probably ticking off the other pony enough for a fight,) which he is an exceptional fighter, he isn't overpowered. He is a pony who would love to not fight but his anger can lead to it unless the pony he is ticked off at is a loved one or friend, but yeah here you go, also he is around 24 so yep (he also has yellow eyes)
one more thing he would care and take care of his friends and family, plus his loved pony. He also comes from an abusive family so meh
