Luna Night is a crossover character from PuppehTales that appears in Backyard Sports: The Great Adventure.
Apon inspection, she looks a lot like a chocolate Labrador mix. It is really unknown what she's mixed with, some speculate husky. She has a really thick fur coat, but tends to wear a suit of technology. She walks like a human, so you might not guess from the back that she's a dog, unless you look at the tail, and ears.
She tries to act like a human, and mostly wears mechanical gloves on her front paws to help her do day to day tasks. Her actions depend on her mood, power level, and if she's bored or not. Basically, if you add her to your team, prepare for some risk and reward.
