Maxwell is the Professor's co-worker and friend. He's energetic, but he can be really serious when he needs to be. He often speaks before he thinks, and he's not afraid to attack. He takes on any challenge by the horns and he gives everything his all. He's the second antagonist of season 1, but just like the professor, he gets a redemption arc at the end of season 3.
He only has 2 lines in the first episode, but he makes an appearance in episode 2, and other appearances with the Professor, then lastly at the end of season 3.
