Bryson

Bryson is one of the seven Diamond Kids. He looks very similar to Cody, besides the fact he is blonde, and his hair is about 1 inch (3 cm) bigger. He is the Cyan Diamond, making him a tech guy. He has a robotic left arm, which is used as a replacement arm from the first time he fought in battle. This robotic arm can stretch as far as he wants it to, and can shoot lasers from the middle of the end piece, which looks similar to the claw from a claw machine arcade game. Maybe the hand came from an arcade game. No one knows.

Q&A
Q= What does Bryson do in his free time?

A= He usually works on updates for the software on his arm. He'll also occasionally browse the web; he likes to watch cat videos on Youtube, which almost always distracts Cody from what he's doing, so Bryson hides in a closet to watch it.

Q=Is Bryson the one who runs the defense systems for the T.D.K.H.Q.?

A= Yes. In fact, Bryson actually made the defense systems in the first place!
