Name: Brian Downstream, or known better as "The Beaver".
Appearance: Brian is a beaver, standing nearly 1.60m with his brown fur, and is a nearly three feet longer with his beaver tail. He wears what used to be a light-green clothing, which has over the years of explosions (gone of too close for good) become more black or brown-ish. He always wear a pair of goggles over his eyes. Other than that, his tail is strong enough to knock down a somewhat sturdy but thin construction, while his teeth can eat over most types of wood.
Personality: Always positive, he's the one who won't take no for an answer nor see problems, only challenges. Even though he might be a nut-case, overly interested in explosions and ways to make things fall apart, he is a friendly person, and wants nothing harmful to happen to his friends.
Skills: construction and destruction, mostly containing something explosive.
