Or
The Irken Empire has fallen to the newly formed Intergalactic Republic! The Diplomacy Center for Peace, which is led by former Resisty leader, Lard Nar, has motioned for an experimental mating program.

Summary
Humans were primitive. Incredibly so. Of all the sentient aliens Zim had had the displeasure of encountering, humans were probably the worst. The irken lamented over this—not for the first time—as his face was shoved into the filthy schoolyard soil. He so, so desperately wanted to extend his PAK legs and skewer the horrible beast pinning him from behind, but he could not. Submission was expected here. He grunted when the hand on the back of his head pushed him harder into the cold dirt.
In which Zim navigates the confusing social dynamics within an Omegaverse AU.
Or, Dib presenting as an alpha leads to a new territory in his and Zim’s relationship. Typical omegaverse smut ensues, with a side of angst and omegaverse social commentary.

Summary
Finishing up Senior year should be easy. That is if you can survive finals, SATs, picking out a college, and figure out what you want to do for the rest of your life. Oh and of course managing to get through the most anticipated social gathering of any High Skool year, Prom. Everything should be a downward slope then. Though that can not be said for our trio of supernatural monster hunters, Dib, Zim and Keef. With Zim and Keef finally becoming part of The Order their nights are never boring. Dib and Zim now go out at night hunting the creatures lurking in the dark side by side, while still trying to manage their relationship. Though things start to turn dire as dark forces creep closer to home. When Gaz becomes a malicious entity's next target, the group has to figure out what it is and how to stop it. Things also start to raise suspicion when the student body of their own High Skool begin acting strange.
This is a part two of a series I am writing. I do suggest reading the first part.
