Appearances The Start of CBLT
Seth Blaine is 17 years old and the son of Huntress Tanis "Viper" Blaine. He is in his first year at Beacon Academy and a member of Team CBLT. Seth is a snake Fanus having the snake eyes, and snake tongue. His weapon of choice is a High Power Sniper Glaive (HPSG) called Soul Anchor and his partner is Lyla Lapis.

Physical description

Seth is very tall for his age, towering over Cleo and Lyla, with pale skin, and shaggy, and spiky dark green hair and yellow-gold snake eyes. He wears a black jacket with the sleeveless rolled up to his elbows, over a long-sleeve dark navy blue shirt, dark pants and black shoes. He also wears fingerless gloves. Soul Anchor, in default mode, is strapped to his on his back.


Compared to the rest of his team, Seth is more of the party kind of guy. He is more relaxed and is very outgoing, despite the bullying he gets for being a Fanus. He never lets the bullying get to him and always leans toward the "bright side of things". With Lyla, he tries to get Cleo to relax more and be more "fun", but to no luck most of the time, but that doesn't stop him.

Seth harbors a crush on Cleo, but it soon learns that she actually has feelings for Garnet. After the rejection (so to speak), Lyla helps him out making him begin to fall for her.
