Kai Green

Kai Green is Ben's first love interest, who makes her appearence in Benwolf. Kai is the granddaughter of Wes Green, a friend and former partner of Grandpa Max. She first appeared doing a spiritual dance in the episode Benwolf. She was Ben's first crush, but she only took interest in him after he started becoming Benwolf because she wanted to, as quoted, "train and tame him". She did have an interest in him before he turned into Benwolf but the interest was about the Omnitrix. When he admitted to this, Gwen gave her a stern talking too. She made a cameo appearance in Ben's dream world in Perfect Day (though it was only a dream).
