Sensei Carlos is a minor character in Clarence.
He's tall, and appears as semi-chubby. He has tan skin, white hair with one braided up ponytail and a receding hairline. He mostly wears a gray martial arts robe.
He is a martial arts teacher, and he teaches students of all ages the masters of karate. He is rather stoic, as he seems to try to not get angry, even when it comes to Clarence and Sumo's stupidity, which personally annoys him.
- His name is loosely based of his voice actor, Carlos Alazraqui.
