Lilly is the tritagonist of Alpha and Omega. She is the younger sister of Kate and the love interest of Garth. While Garth and Kate were initially supposed to marry to bring the two wolf packs together, Lilly and Garth ultimately fall in love with each other.
She has white fur with purple eyes.
Lilly is a friendly, fun-loving wolf and has a totally opposite personality from her sister, Kate. She doesn't have very much self confidence, until she meets Garth.
Unlike her sister, Lilly isn't so shallow as to instantly dismiss someone just because of bad howling. She takes an immediate liking to Garth when first she sees him, and wants to get to know him, offering to show him around her pack's territory. During their time together, she wins him over with her turtle impressions, and Garth tries to teach her some of his alpha moves.
When she shies after a little mishap, Garth pushes back her hair and compliment her eyes, leading her to start wearing her fur back, and start being a little more confident. She then helps Garth improve his howl and they howl together, realizing they're in love.
Lilly tearfully attends the wedding between Kate and Garth but is overjoyed when Garth proudly admits he fell in love with her.
While Lilly isn't as outgoing as the other omegas, she still has a sense of humor and likes to have fun in her own ways.
