Mr Mathsuxs is a teacher in Ride School. He teaches math to TARS, GT, and Dogs characters. He is the homeroom for Dogs.
Mr. Mathsuxs really hates math, even though he teaches it.
Unlike Mrs. H, he is not a dog, despite his homeroom kids are the dogs characters.
There were some ideas by Poyo's friends before he was the guy who hated math.
- One suggestion was that he would be a gamer, always playing a handheld during class.
- Another was an idea where he was obsessed with another subject that he does not teach.
