Bart is a False Vampire Bat who's very sweet and considerate. He's super smart and nerdy, but doesn't like to show it off all that much. His hobbies are card games and playing/ making video games. He currently lives with his fiancee, Rita. The two are basically married but want to be more financially stable before calling it official. Since his fiancee tends to work overtime, Bart often does the housework. Rita always lovingly teases him for dressing like a super nerd, but he embraces it. Otherwise he tends to dress in baggy gaming shirts.

Bart originally worked at a large company developing phone apps and software with Ziva. He also worked in QA to design phones and accessories to cater to different animals. The two later left once they heard about a well-known indie game studio moving to their area. He primarily makes game engines and specializes in game AI. His favorite kinds of games are RTS's, RPGs, platformers, and rogue-likes.

Despite being only 4 and a half feet tall, he towers over his parents. When he has wings, he's capable of flying but struggles with it a little bit. He also speaks with a very, very slight Australian accent; most people don't notice until they're told.
