BB-Glack
BB-Glack is a teacher on Centera, he is very dangerous because if someone asks him any questions that aren't about his class he will eat them. BB-Glack has a gelatinous body with two eyes sticking out of his head. He is also from an unknown planet, and since he eats everyone who asks him where he is from, nobody knows where he lives. It is also unknown if he has any relatives. BB-Glack also has a reputation for teaching 40 years and never had a kid fail, he never passes them on purpose either, he just makes sure everyone is paying attention and helps anyone who needs help, some say he can sense when a kid doesn't understand a problem. He teaches math, physics, earth history, and UU history.
