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.
Butt Monkey: As an Omega, he's a comic relief by class and duty. The film never lets you forget that with all the stuff that happens to him.
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.
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: He is the closest to one in the first film, albeit as an Anti-Villain. He's the main antagonist of the film because he insists on the Arranged Marriage as the only way to merge the pack to ensure his pack's survival and is threatening to declare war if it doesn't happen. He eventually does when he finds out Garth has fallen for Lilly. With a little "encouragement" from Eve, of course.
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.
Cut His Heart Out with a Spoon: She's got a Moe Szyslak-like habit of threatening people with painfully detailed deaths when they threaten her pack or daughters...the first two being in a calmly happy voice...
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.
Big Bad: Of Alpha and Omega 2: A Howl-iday Adventure
Genre Blindness: He's so obsessed with the notion of strong Alphas that he's easily deceived by Humphrey and Garth's "big Alpha" routine, laced with plenty of Bad Bad Acting, not realizing he's been fooled until Runt has just been rescued.
Shadow Archetype: In a sense, he is a darker version of how Tony was in the first film. Both are parents who would use their children in their plans and desire a sense of "purity". But whereas Tony's motivations were adhering to traditions and ensuring the livelihood of his pack through unity, King's motivations are purely the belief that he and his Rogues are superior and a basic lust for power for the sake of itself. And while both intended to take the territory for themselves, Tony wanted it for the resources whereas King wants it purely to take it as a demonstration of his power.
The Social Darwinist: Believes in and is obsessed with the "purity" and strength of Alphas and his Rogues, also being quick to mock any sign of weakness
