KPop Demon Hunters (2025)

We Need a New Weapon

by Ashtree11

The Honmoon has been fractured for a long time, and from its tears arose behemoths who pose an existential threat to humanity. And so to fight monsters, they became monsters. Jaegars, effectively giant mechs, we’re built to hunt and destroy these demons. Rumi, in the shadow of her mother’s legacy, is slated to become a pilot of these massive weapons. But a larger and far darker shadow also hangs on her shoulders, one that she can’t afford to let her co-pilots learn. The fate of the Honmoon, and the world depends on it. Or A Pacific Rim AU that wouldn't leave me alone

The Myth of Mankind

by MistressEast

Ten years after the World Blaze, the Parnassus successfully migrated to Omega Centauri, narrowly avoiding the destruction of Earth. The project’s young visionary, Kray Foresight, quickly took leadership, guiding the small colony into an uncertain but hopeful future, and the colonists honor the hundreds of Burnish who willingly gave their lives to bring them there. Twenty years into that future, Galo Thymos, the Governor’s young adopted son, finds himself adrift. Working as a terraformer and expected to follow in Kray’s footsteps, Galo pines for more adventure than the tiny, insulated colony can give him. When he’s enlisted to help Lucia gather some data on the sealed interior of the Parnassus, he jumps at the chance, eager for a little excitement, but what he finds down there throws his narrow world into complete chaos. Now on the run with a myth brought to life, Galo is forced to face the reality of what happened twenty years ago and the truth about his own father, but, as he and Lio grow closer, he realizes Lio may be the adventure he’s been seeking all along.

My Dad is Bad but still

by KayHau

Life was simple. My dad loved me, everybody else hated me. I didn't have friends, or a mom, or an uncle, and certainly not some prophecy about a Green Ninja hanging over my head. Life is complicated, and scary, and uncertain - but, for the first time in my life, I'm not lonely. It just may be worth it. -Movie-verse AU in which Garmadon raised Lloyd. Beta: Sunny Lighter.*Note, cross-posted on Fanfiction.net.

My Dad is Bad - Bonus Scenes

by KayHau

A place for shorts, oneshots, and/or drabbles, all taking place in the My Dad is Bad universe, but that would interrupt the flow of the main story. Shorts may take place in the past, present, or future and, at least so far, are pretty much all fluff.
