Kane is the elder brother to Sydney and Kyzil's best friend. He has his mother's appearance but his hair is short. He uses a gun for his weapon of choice.
Despite holding a sense of honor, Kane has no interest of carrying his family's legacy. He'd rather become a spy. Kane is seen as strict but kind and was reluctant on joining the team. However, he loves his family and will protect them at all costs.
Upon their first meeting, Kane distrusted Raiden and her group but relented after having an intense discussion with Sydney, stating to him that Raiden was their best chance at saving their parents. Kane continued to act coldly towards the outsiders until forming a friendship with Kyzil, the both of them wanting to work in law enforcement and sharing similar interests and beliefs regarding criminals. Kane begins warming up to the rest of the group too after watching Raiden save Sydney from falling off of the Eiffel tower.
