His first choice of mate was a grayish-brown lioness named Bruma, but eventually chooses a golden-brown one, Kairel, instead, at first because she is the only lioness left, but later becomes seduced by Panthy. After he is framed for "trying to eat a grasswhopper" (as believed by others when they use fake blood on them both) and captured, and almost loses his animal kingdom to Dagnino, then he realizes the error of his ways, but is freed by Kairel, whom he accepts forever.
