Story Title: Ultimate Yang

Story Start…

At a nearby Mr. Smoothie restaurant, Yang just stood next to her beloved motorcycle, Bumblebee. As she lazily drank from her mango tangerine smoothie, she thought back to what had occurred in recent times. Ben and Rook were off with their girlfriends enjoying a nice, calm day off, and she was also given the day off but has nothing to do.

And that meant that she was pretty bored.

So Yang did what she always does when she's bored. She activated the Ultimatrix and cycled through the aliens she had unlocked. Thankfully, Azmuth had reset the Ultimatrix before giving it to her, so that meant that she had quite a variety of aliens at her disposal.

But when it turned from green into the gentle lilac color that was her eyes, she was a bit perplexed. Thankfully, Ben had explained to her that like his Omnitrix, the Ultimatrix was designed to key itself into her DNA and graft itself to her forearm so as to not be removed so easily by those who would use it for evil purposes.

The color change signified that Ben's DNA was no longer the default setting. Now it was Yang's OWN DNA that was the default for the Ultimatrix. Which begs the question…

What in the universe does this mean for Albedo since HE also has an Ultimatrix?!

...On second thought, I don't want to know.

Unlike Ben, however, she only has access to about ten DNA samples until she unlocks more herself. She's given her transformations names of their own that are different from Ben's, but you all know these ten as Humungousaur, Wildmutt, Gravattack, Arctiguana, Spidermonkey, Rath, Big Chill, Echo Echo, Stinkfly and Cannonbolt.

Yang was a little frustrated as well. Jaune had left Vale and Beacon with her that fateful day, but he was actually getting ready for a visit from his family. So that means that she has no company in the form of her boyfriend.

What's a poor, bored and frustrated girl like her to do?

A loud explosion down the street caught Yang's attention. She smirked and hopped on Bumblebee before putting on her helmet and riding off. Beating the heck out of some villains oughta put a smile right on her face!

It'll be good for some stress relief, that's for sure.

Little did she know that she'd be meeting some figures from her past. Some of them being most welcome… And some being ones she'd NEVER wanted to see again!

"I guess it's time to kick this day off with a Yang!" she said to herself.

She laughed at her own stupid pun, and came to appreciate one more thing about Jaune. The boy genuinely thinks her puns are funny. He just doesn't show it that much while they're in public together.
