Title: Dawnie Does the Marvelverse
Author: JoeHundredaire
Rating: PG-13/FR15.
Disclaimer: Right, I actually went and checked to be sure this time… after being passed around like a slut at a frat party over the past few years, Buffy the Vampire Slayer, Angel: the Series, and all associated characters now belong to Warner Brothers. With a myriad of writers, artists, and editors - and directors, now that we're getting decent movie and television renditions - actual rights are a nightmare when you go near a comic book universe. Suffice it to say that Marvel Entertainment LLC owns all of the property printed in their comics, along with the television and movie adaptations of said same property. Not mine, don't sue, and so forth and so on.
Summary: Dawn Summers decides to disregard the Scoobies' advice and have a heart-to-heart with a vengeance demon. Adventures ensue.
Joe's Note: This is mostly a proof-of-concept for an idea I wanted to integrate into the future of Trigamy, which some of you may recognize if you read through the Halloween arc of the original version of the story. The story will occupy a universe that's loosely based on the X-Men: Evolution cartoon insofar as most of the characters we know and love are either high schoolers or young adults. That being said, I'm not going to be sitting here trying to match ideas to rewritten versions of specific episodes, and so you're going to be disappointed if that's what you're looking for.
Dedications & Thanks: To Alexander, Nicholas, Nathan, Vi9, William, Koby, Wil, Thomas, Tracy, Christopher, Mitch, and Jess for sponsoring me on , and making it easier for me to spend more of my time writing.

"Humidity is rising… barometer's getting low. According to our sources, the street's the place to go. Cuz tonight for the first time, just about half past ten… for the first time in history, it's gonna start raining men!" Dawn Summers did her best to keep a straight face as the large, blue-furred man in the room with her cringed but refused to look up from his computer. His fate was his own fault, though, at least in her opinion. Okay, fine, so he felt the need to run assorted tests on her DNA. That didn't mean she had to stay here while he performed them, did it? She'd been dropped into his boss's office via magical, interdimensional portal with nothing more to her name than the clothes on her back and the iPhone in her pocket. Where was the harm in letting her wander around the school she'd seen brief glimpses of on the way down to the lab? What was she going to do, run off? With no money, no one to help her, and nowhere to go? "It's raining men! Hallejulah! It's raining men! Amen!"

There was a crack as Doctor Henry McCoy gripped the edge of his desk a bit too hard, and then the mutant sighed before looking back over his shoulder at Dawn. She imagined that most people would find his fierce, blue-furred, leonine countenance a bit intimidating. They hadn't had to deal with Buffy on her period, though. "Miss Summers. While I understand that you may find this boring, these tests are essential in determining two very important things. Firstly, given that you are a minor, we need to figure out what to do with you. Secondly, it is imperative that we discover what - if any - other special abilities you might possess."

Dawn shot a glance down at her hand, curling her fingers into a fist and watching as the digits transformed from flesh and blood to glittering diamond. Evidently 'Hallie the Guidance Counselor' had given her a bit of an… upgrade… before dropping her off at Mutant High. So far, Dawn had transformed her entire body once by accident and her left hand a few times on purpose. While the idea of powers didn't necessarily freak her out because again, Sunnydale native… accidentally turning herself into diamond in the middle of the mall would probably provoke a 'burn the witch' type reaction from the average citizen. Knowing what she was capable of and how to control it sounded eminently practical to her. Knowing if there was someone out there who could claim her, so she didn't end up living in a box or a foster home? Also a good idea. It was just so boring! "I'm hoping the last names are just a coincidence, and I'm not related to that Scott kid. He seemed like a bit of a tool."

"During your sole encounter with him, you exchanged twenty words at most."

"Unlike my sister, I have a high-quality tool-o-meter."

"I see."

"Yup." Looking up, Dawn spotted an unlit examination lamp and carefully grabbed the edge, guiding it down so she could study her reflection in the glass. "Also unlike my sister? I appear to be a natural blond these days." She'd first noticed it when a few flyaway strands drifted into her face on the walk down; while her hair had come through the transition with its length and texture intact, Hallie had decided to turn it platinum blond for no apparent reason. Or maybe some apparent reason. "You know, everyone I've met here so far looks at me like they've seen a ghost. Why do I have the feeling that you know what those tests of yours are going to say?"

"While I may have my suspicions, Miss Summers, if there is one thing that I've learned the hard way over my years as a scientist, it's to never count my chickens before they're hatched, sexed, and inoculated." The computer beeped and McCoy turned back to his work, his claws clicking against the keys as he muttered softly under his breath. "And here we are. Well, it seems that I have both good and bad news to share with you. The good news is that I have located a ninety-seven point five percent allele match in the databases I have access to, meaning you do have family here in our world. In another piece of good news, that person is a mutant - meaning we can make a very educated guess about what your full power set might be - and on top of that… the match is not in fact Scott Summers."

Letting out a sigh of relief, Dawn slid off of the table she was sitting on and made her way over to the good doctor's desk. "And the bad news is… it's someone you hate, isn't it?" Pausing, she thought back to the brief history of this dimension that she'd received after convincing the scary guy with the weird hair to stop trying to stab her to death. Based on how few of this world's prominent and historical figures were familiar to her, though, Hallie had tucked her away in a dimension pretty far from home. Which meant that it'd be harder for the Scoobies to track her down, which in turn increased the importance of finding a way to fit in and survive here in this strange new world. "Lemme guess, that Magneto guy that Xavier's gone all Hatfield 'n McCoy with? Which would really suck, because the man may be a genocidal douche, but he's got two really hot daughters. Who are a whole lot younger than him, now that I think about it, which means that someone was robbing a few cradles…"

McCoy shot an unreadable look back over his shoulder at Dawn before shaking his head and returning his attention to the computer. "No, you are not a Lehnsherr. Your guess isn't that far off-target, though. While we haven't quite reached the level of 'hatred' yet, the Institute's encounters with the family in question have been largely unpleasant. Four children, all mutants, and all of them rather egotistical and selfish when it comes to the usage of their powers." Opening the computer's Internet browser, McCoy tossed a phrase that Dawn didn't catch into the navigation bar. Within seconds, Google was returning a mix of news articles and website links, separated by a series of pictures of a very pretty teenage girl who shared Dawn's new hair color. "Tell me, back in your world… were you at all familiar with the Frosts?"
