Rowan

Rowan is a teenage boy, around the same age as Ben. He was known to have bullied Ben in his past during his time at the orphanage. He is mentioned a few times by Ben and makes his first appearance in the fourth book. He approaches Ben and starts to cause trouble but is scared off by Kai. In the beginning of the fifth book, Rowan turns up at Cliff's mansion with Ben, who is supposedly deceased, but there is no explanation just yet.
