Summary
The monsters were nearly on us when the truth finally came out.
"Daniel." My uncle took both of my shoulders in a vice grip and pulled me in closer, a manic frenzy in voice - probably from sheer mortal terror - and looked me dead in the eyes. "Your father is the Greek God Apollo."
I didn't miss a beat.
"Well, I'm screwed."
...
Or:
A Demigod of the Sun gets access to the Multiverse.
Shenanigans ensue

Summary
Reality unraveled, and Luna with it, the tapestry of cosmic power and mortal memory that was her everything scattered and erased from existence.
A death so complete, so magnificent, that even gods would have stopped to watch in awe.
And when the light flickered out, and the clearing settled, Luna Lovegood was gone, and not even dust remained.
...
Somewhere, far away, a child was born anew.

It is said that the Blue-Eyed White Dragon represents power, while it's counterpart, the Red-Eyed Black Dragon represents potential.

Summary
Aurora 'Rory' Morningstar finally had her life on track.
It only took self-actualising the ability to time-travel, nearly getting killed by a lunatic with a grudge against her dad and finally getting back home after getting the catharsis she'd longed for all her life.
Things were looking up.
So when she somehow gets herself blasted out of the universe and into one that was far more ridiculous, she's not amused.
She's very not amused - snd she intends to make that everybody's problem.

Summary
"Reverse Cursed Technique."
Fuyuko will nod as if she understands, even though she'll have long since given up hope of ever making sense of the impossibilities that chase after her son like moths to the flame.
"But how did you know to use it?"
"I just knew. I always know stuff like that." He'll shrug in answer, utterly nonchalant and forever at ease. "Throughout Heaven and Earth, I alone am the Honored One."
"What does that mean?" She'll ask in response to that proclamation, and her child, her Limitless boy will return her look with cerulean eyes brimming with more power and potential than any Byakugan could ever hope to match, and he'll smile.
"Mama, I have no idea. Isn't that awesome?"

Tags
Summary
She was herself a winter child, and the cold that snuffed out all warmth and heralded the harshest of seasons was as much a part of her as it was of the ice dragon.
So when the young dragon landed before her, half again the size of a mammoth and near enough to swallow her whole in a single bite, Adara did not shy away from it.
Instead, she raised a single tentative hand and pressed her palm to the mighty beast's snout as none had ever dared to before.
"Hello." The girl whispered in awed delight, hand tracing hoarfrost-sprinkled scales ever so gently. "Won't you be my friend?"

Ikaris did not simply fly too close to the sun. He flew straight into it's heart, seeking an end to all that he was and ever would be.

In many ways, that was only the beginning
