Dr. Starline is a new mad scientist introduced in the Sonic IDW comics. He is the one who made Surge the Tenrec and Kitsunami who they are and the way they are now. He keeps them in line with the gem on his glove which he can use to hypnotize others, give himself super strength, super speed, or super agility. (you can be whoever you want even an OC of yours)

This is class 1-A each student is a Demi-human, you'll find out what their animal halves are sometime along the way. (don't mind the voice) you can be your own character (you have to be a Demi-human though), or one of the students, and if you are one of the students they will be an entirely new student that just joined the school.

Spinel is a character from Steven Universe. (you can be your own character) (I couldn't really find a good picture that looked that similar to Spinel, sorry.) 😞
