Kai Green

From Wikitrix

Kai is the granddaughter of Wes Green, a friend and former partner of Grandpa Max. She first appeared doing a dance. She was Ben's first crush, but only took interest in him after he started becoming Benwolf because she wanted to, as quoted, "train and tame him". When she admitted to this, Gwen gave her a stern talking to. She reappears in Ben's dream world in "Perfect Day".
