All Men Are Perverts: Humphrey looked really excited after hearing about repopulating.
Anguished Declaration of Love: After Kate is seemingly killed in a stampede, he, heartbroken, tells her he loves her and howls in her memory along side both packs. It was a Disney Death, but still, it's a rather emotional scene.
Plucky Comic Relief: Not just for the movie, but plays this role in the pack. He uses his nack for comedy to ease tensions and break up fights, something his valued for being able to do.
Tuck and Cover: During the stampede at the end, he jumps on the unconscious Kate to protect her from further harm. This also convinces her father to let them mate.
Child Marriage Veto: She backs out of marrying Garth at the last minute and announces she's in love with Humphrey. Thankfully, Garth felt the exact same way and had fallen for her sister. Sure it took a Disney Death on Kate's part to get it accepted, but still counts.
Small Name, Big Ego: She thinks of herself as the greatest and most responsible alpha wolf and seems to point out the flaws of others, most notably Humphrey.
Character Development: Garth starts off Jerk Jock that thinks he's perfect. But he gradually grows into a more caring character who accepts and tries to fix his faults, even if he needs help from an Omega to do it.
Child Marriage Veto: After Kate backs out and admits she loves Humphrey, Garth decides to veto the marriage as well by admitting he's in love with Lilly.
Appeal To Tradition: His justification for the Arranged Marriage as the only way to merge the packs. While that time it's not that bad, later, he declares war because Garth has fallen in love with Lilly and 'an Alpha and Omega can't mate'. He eventually decides to change after his stubborn actions nearly got himself, Winston, and Kate killed. Oh, and Eve 'helps' bring him around a bit too. Even he knows making her mad isn't a bright idea.
Big Bad: Well as close to one as this movie has. He's the main antagonist of the film because he insists on the Arranged Marriage as the only way to merge the pack and is threatening to declare war if it doesn't happen. He eventually does when he finds out Garth has fallen for Lilly.
Evil Redhead: Not so much in the way that he's evil, but acts more like the antagonist. He also has, at least in some views, red fur or brown fur.
Berserk Button: Whatever you do, do NOT harm any of her daughters unless you want to risk having one of your body parts ripped off and shoved down your throat.
Actually, the first time it was just a member of her pack, so even that carries a risk or grevious bodily harm.
Cut His Heart Out with a Spoon: She's got a love of threatening people who threaten her pack or daughters with painful deaths...the first two being in a calmly happy voice...
Eve: If any of you wolves have hurt my daughter, I will personally RIP out your eyes, and SHOVE them down your throat so you can see my claws TEAR YOUR CARCASS OPEN!
OOC Is Serious Business: Her first two threats are given in a happy tone. After her daughter vanishes, her giving her threat in an angry and serious manner shows just how big of a Mama Bear she really is.
