A plot could be that Kate's pregnancy is different from the typical alpha - omega pregnancies. It could be that she has some special powers or abilities that are passed on to the baby during pregnancy, and there are some in the pack who are jealous or afraid of this. The story could also show how the omega community in the pack comes together to support Kate during her pregnancy. They might share their own experiences and wisdom, which helps Kate navigate through this new and sometimes scary journey.
One idea could be that Kate's pregnancy is a big surprise to everyone in the alpha - omega world. Her alpha mate has to quickly adapt to the idea of becoming a father and deal with the new responsibilities. Another plot could involve some sort of danger during the pregnancy, like a rival pack seeing her as a vulnerable target. Maybe there are also some ancient alpha - omega traditions related to pregnancy that Kate has to follow, which creates some interesting cultural clashes.

One idea could be exploring a new mega evolution for a less - known Pokemon in the Hoenn region. For example, making Linoone have a mega evolution with a unique design and new abilities.

One idea could be that the OC is a new wolf in the pack. Humphrey, being the alpha, has to teach the OC the ways of the pack. This leads to them spending a lot of time together and gradually falling in love. Another plot could be that the OC is from a rival pack, but she and Humphrey meet by chance outside of pack territory. They have to keep their relationship a secret at first because of the pack rivalry. A third idea is that the OC has a special ability that the pack needs, and Humphrey has to convince her to stay with them. During this process, they develop feelings for each other.
In a post - apocalyptic world, Kate, an alpha, and the human soldier cross paths. The soldier is part of a group trying to rebuild society.

They form an alliance which gradually turns into a deep emotional bond.

One idea could be a new student arriving at the school who turns out to be an alpha from a powerful family, and there's immediate tension with the existing omega students. Another could be a school event where alphas and omegas have to work together on a project and unexpected friendships form. Or perhaps a story about an omega who defies the typical roles and becomes a leader in a school club, much to the surprise of the alpha students.
The story can explore family through Kate's relationship with her alpha mate. Their journey into parenthood can show how they form a new family unit. For example, they might have to make decisions together about the future of their child, like where to raise it. Also, Kate's pregnancy can bring her closer to her own family within the pack, who may offer different kinds of support.
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.
