Summary
I met a traveller from an antique land,
Who said—“Two vast and trunkless legs of stone
Stand in the desert. . . . Near them, on the sand,
Half sunk a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed;
And on the pedestal, these words appear:
My name is Ozymandias, King of Kings;
Look at my Works, ye Mighty, and despair!
Nothing beside remains. Round the decay
Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away.”Percy Shelly’s “Ozymandias” (1819)

Summary
The legendary genius Azmuth studied Earth for centuries until he connected to its mana, creating the Grimoire of Transmutation, capable of channeling the power of countless cosmic life forms. Before dying at the hands of Vilgax, he divided the grimoire into lost pages, scattering them throughout the world. Centuries later, in the Clover Kingdom, a magic-less boy named Asta dreams of becoming the Wizard King. One starry night, a "shooting star" falls before him—Azmuth's Grimoire chooses him as its new wielder, sealing in his arm a power beyond all known magic. Now, with a mysterious bracelet and the strength of beings from other worlds, Asta must unravel the origin of this power and face enemies who seek to control it. The fate of magic—and perhaps the universe—hangs in the hands of the mana-less boy.

Summary
When Mirabel was ten, she found the Omnitrix and became the shapeshifting-powerhouse hero, Shifter. And for five years, she's been a hero, until she decided to go for a normal life and retired from wearing the Omnitrix. Although you've been retired, there are still moments when people remember the shapeshifting heroine who helped save cities and people from super villains. You were practically the first superhero ever.
Now at 23 years old, Mirabel feels like she's wasted the last three years on a loveless relationship with Barry Allen, AKA The Flash. Barry asked you out while Iris was still dating Eddie. Years later, it's obvious that he'd rather be with her, but he just won't admit it or let you go. This has been killing you for years, and Savitar has pushed you past the point of no return- there is no ignoring the situation, your heartbreak, anymore.
Mirabel now has that chance once more when Azmuth comes to her for a mission in space and to be prepared for a threat bigger than anyone has ever known.

Summary
The relationship between Ben and Kai always seemed a little rushed to me in Omniverse, so I thought that I'd make my own two cents into it, flesh the romance out by actually giving them a relationship that'll grow over time, love it or hate it but I'm definitely writing it, it'll be a mix of group text and normal but honestly I cannot wait to see how it'll turn out.
