Ben

Ben Miller is the boyfriend/fiancé of Cole, the brother of Lila and the son of Sophia and Sebastian. He was made an official member of the ninja team by Jay in the fourth book and is a Kitsune, a nine-tailed fox spirit. He was a former villain and is an ex of Nya. He made his first appearance in the first book when he came looking for his so-called 'girlfriend'. After finding out that Nya was now dating someone else, he seeked revenge on the ninja and turned to the dark side to join Nadakhan and his boss, Clouse. He was later taken down by the police at Chen's Island after the sudden death of Cole and stabbing Jay. Ben was later let out of Kryptarium Prison due to choices Jay had made and wanted to make things right with the ninja. After making an effort to show he had changed, the ninja were showing no change in emotion towards Ben so he turned to the dark side once more to set Nadakhan free from the Teapot of Tyrahn again. He then met Jake, who agreed to be his sidekick and fought the ninja at the Wailing Alps. He showed revealed Jay's true past and felt guilty about his intentions. He then left and went missing for a little while. During Jay's time in Kryptarium Prison, due to being framed for the murder of Cliff, Cole helped Ben out behind everyone's back. He was known as 'Caspian' at the time. He was later to be revealed as Ben and he began to grow feelings for the master of earth. The two soon became a couple, also known as Colen, which sparked some drama between the ninja and Cole's father. Ben then became an ally of the ninja but they still found it hard to trust him. Ben then risked his life to save his friends and most importantly Cole, gaining everyone's trust. He died in Cole's arms but was quickly brought back by Kitsune magic, which was when he was revealed to be the supernatural spirit. After everything with the explosion after Jay's welcome home party, Jay made him an official member of the ninja team. He then later proposed to Cole and was rejected. He eventually told his boyfriend about his true past and found out about Jake, his old sidekick and friend, being in love with him and killing his younger sister so many years ago. Ben was later murdered by Jake and a funeral was held. But he is now back again with no explanation just yet. He and Cole are now engaged and are awaiting a Colen wedding.
