Serpent is Keira's second and one of her most trusted Monsuno. Catera previously owned Serpent, but gave it to Keira because she had only 1 Monsuno and felt left out because everyone else on the team had more than one. He is a sea serpent, and he is great when it comes to battling S.T.O.R.M and Eklipse. He gets along great with Ripper, and is protective of Audrey and Team Core-Tech. Just like Lock, Serpent believes that Monsuno and mankind can coexist peacefully and is determined to prove those who don't wrong. He is a great addition to Team Core Tech.
Serpent is blue (for Core Tech) and has light blue diamonds all over his skin. He has very sharp teeth that can cut through anything.
