I present you with my first moderately-successful attempt at drawing a MLP:FIM character! If you're wondering why you haven't seen this one anywhere, it's because I just made her up! Like, just today! Anyway, here's a short bio...
Firebrand is, as the title suggests, the product of a dragon and a pony, who she lives with. Ambitious and eager, she works for her mother, helping to clean up her studio as well as running errands. Her dragon-clawed feet give her the ability to run much faster and maneuver much better than even the most athletic pony. (That, coupled with her innate strength and stamina, makes her go-fer job a lot easier!) Though she lacks the horn, she does have unicorn blood. With it, she is not only able to breathe fire like her father, but actually manipulate it as well!
Firebrand is a late addition to, and the youngest of, the Cutie Mark Crusaders, and is especially close to Sweetie-Belle. Although all four of them have already received their cutie marks, they've kept the team together well into their adulthood. They continue to go on daring quests whenever the opportunity arises. (This is often to the chagrin of Firebrand's mother. She's very confident in her daughter's ability to handle any situation, but she wishes she wouldn't track all that dirt inside!)
Her special trait is courage, and she's always willing to encourage anyone who needs it. Still, it's hard for her sympathize with others' weaknesses in that area (like Fluttershy), so she sometimes ends up being insensitive and discouraging. As it is, she only wants to help.
