The unique part could be the relationship between Kate and Humphrey. In the 'alpha and omega' world, their dynamic might be different from the original story in the fanfiction. It allows for new interpretations and character developments.
Kate and Humphrey's love story in 'Alpha and Omega' is really charming. They are from different wolf packs, an alpha and an omega. Despite the differences in their status within the pack, they are drawn to each other. Their love overcomes many obstacles, like the traditional pack hierarchies and the conflicts between their respective packs. Along their journey, they learn about each other, grow together, and their love blossoms in the face of difficulties, making for a heartwarming and exciting story.

Love against all odds is also quite prevalent. Given their different natures as an Alpha and an Omega, there could be obstacles in their relationship. But the fanfiction often focuses on how they overcome these differences and fall in love. For example, Humphrey might be seen as too carefree for Kate at first, but as the story progresses, she realizes his positive qualities. In addition, themes of family and loyalty can also be found. Their relationship may have an impact on their respective packs, and they have to balance their love with their loyalty to their families and packs.
Another common theme is the struggle to overcome differences. Kate is more of a traditional alpha, while Humphrey is a bit more laid - back. Fanfictions often explore how they work through these differences to be together. It could be about how Kate learns to relax a bit and Humphrey steps up his game to be more alpha - like at times.
