A/N: This does finally reveal one of Rose's biggest secrets. Want to keep it secret a while longer and postpone that glorious dramatic irony? Don't read, or come back to this later. I'm sorry I was unavailable to post this weekend, and combined with this not being part of the actual storyline, you get to chapters. ONce I make a cover, this will also be posted as a separate Omake this Wednesday. Enjoy!

[Infinity War Final Battle]

The Avengers were losing, and they were losing miserably. There was no other way to put it. Thanos had all six stones and he was about to Snap. "I am Inevitable." He said, sure, that, at this point, nothing and nobody could stop him.

Except as he was about to, he found his hand wouldn't work. It was frozen in a pre-snap position.

A spot of sheer darkness spread a few feet in front of Thanos, and out of it stepped the figure of a young woman and a very large panther, with spikes pointing out on its neck, snarling at Thanos.

The Wakandan's were in awe. This was the legendary Nundu, an adolescent one, but it was tamed by this person.

The young woman, still partially in the darkness of the cloud of darkness so she wouldn't be seen except for her figure, talked to Thanos. "Yeah, big purple guy, I don't think so."

"Who are you to stop me? I am inevitable." Thanos told her, yet again sitting on the nearest piece of large debris he could find.

"Yeah, no. I don't think so. See, while you may have done me a favor, I'm not a fan of the Avengers either, and normally I would have even let you do whatever the bloody hell you wanted to. But you made one single mistake, and you're going to pay for it."

"So you don't like genocide?"

"No, if I judged you for mass genocide, I would be a hypocrite. I've done my fair share of it, although they all deserved it. Does it count as genocide if a majority of the population are murderers and tried to kill me? Anyways, I care for exactly a dozen people in the whole universe. A dozen living beings you had to avoid killing."

"So you want to stop the Snap so some of them don't die?"

"No, I'm not incompetent. We're immune to your silly little snap. No. You purposefully killed my father, and for that, you signed your death warrant."

"I'm righting the balance of the universe. So your father, whoever your father was, was most likely extra."

"Oh no, my father was an enemy of yours. See, I thought of going after you when you decided it was a good idea to poke around in my father's brain. But I left you alone. I would have been a bit pissed if you destroyed Midgard, I was born and raised here. But that's alright, you did me a favor with your contribution to the destruction of Asgard. Never liked the place."

"I don't care, but you are my enemy, so I will end you." Thanos tried to aim the infinity gauntlet at her to get rid of the annoyance, but it didn't work.

"See, my dad wasn't smart enough, he attacked you straight-on. I won't make the same mistake. Meet my Flerken-Nundu, Goose. She's a fan of the C-53 System, especially the United States of America, and doesn't appreciate its destruction. The best thing about selectively poison breath is that it can immobilize anyone, not only Midgardians, but also Aesir, Celestials, and literally anyone else in the universe."

"So who was the man I am supposed to regret killing?"

"The ones whose mistakes I won't repeat." Thanos was lifted off the ground and riddled with a couple of dozen daggers. "Adamantium and vibranium blend. Works every time." She then cut off his head, exploded his chest, and sent a burst of flames to incinerate the Mad Titan.

Thanos' troops, too shocked at the quick and effective death of their leader, were promptly decimated by the hope-filled Avengers and Wakandans.

When all of the enemies were rid of, there was clapping from inside the dark cloud, which dissolved to reveal Thanos' defeater. "Bravo, Avengers. Not as useless as you usually are."

Cleaning their weapons from the blood of their enemies, the Avengers turned to the young woman. "Thank you for getting rid of Thanos." Steve Rogers told their mysterious savior, temporarily covered in darkness again as the dark cloud dissolved.

"He got what was coming to him." She answered darkly.

"And who are you, oh mysterious savior of the universe?" Tony Stark asked in his usual sarcastically joking manner.

"Rose Potter, pleased to meet you." She had flame-red hair and looked as human as they came. If she had not used a variety of supernatural forces to defeat Thanos, none of them would have believed she was not an ordinary earthling human.

"Pleased to meet you. I am Thor Odinson, King of Asgard." Thor introduced himself.

She gave him a measuring look. "I know. Although you might recognize me better by a different name." She drew her hands in a strange pattern around her, and what looked like a disguise melted off of her. The resulting young woman had inky dark black hair instead of the previous vibrant flame red, a skin tone that was pale instead of tanned, and when her eyes shot open, they were not her previous hazel brown, but instead, they were a vibrant, glowing emerald green color. Overall, the resemblance was uncanny. "Lilith Lokidottir, rightful Queen of Jotunheim. Not nearly as pleased to meet you, dear uncle," she answered in a much smoother, silkier voice that further cemented the proof that she was the daughter of the man often known as Silvertongue.

"Jotun?!"

"Why would you prefer me to look like a fearsome monster of fairy tales? Become the monster parents tell their children about at night?" And she morphed, her skin getting dark blue swirling patterns and a lighter blue hue, her eyes red, although still glowing, adding to the fearsome effect, a snowflake twirling around in her palm. She morphed back into her dark-haired, human-looking form. "I have better things to do than to pander to your sentimental needs, Odinson. I have a godson that still hasn't finished his magical training, and I have exhausted too much energy to teleport to Vanaheim."

"My brother Loki had a daughter on Midgard all this time? Why didn't he tell us?"

"Dad just didn't tell you or Odin. Queen Frigga, I'd met until I hear, your foolishness got her killed. Did you truly think Odin would accept the daughter of a Loki, directly in line for the throne of Jotunheim, who he had no jurisdiction over, whose magic is even stronger than my father's? My mother was from a long line of Midgardian Mages, which amplified Dad's Aesir magic. Now, if you will excuse me, Odinson, I have a Godson to train and a palace to rebuild."

"Will you return?"

"To Midgard, probably. Goose is, for some reason, extremely fond of this planet. Especially some superspy named Nick Fury. If you want me to come to Asgard, I want the Casket of Ancient Winters back, I know it wasn't destroyed. Which one of you is Tony Stark?"

Tony Stark lifted the visor of the Iron man suit. "That's me. You're not going to go Loki Junior on me or anything, right?"

"I sincerely hope that was meant as a compliment. Either way, I owe a favor that was called in."

"And I have, what, exactly to do with it?"

She flicked her finger at him and a beam of light rushed out. "You'll figure it out. Also, I'm taking the stones because you have all proved you are incapable of keeping them safe. Tu-ta!" And she disappeared just as suddenly as she had appeared, leaving a dead titan, his decimated army, and no infinity gauntlet or stones behind.

"Am I hallucinating, or did everyone just see that?" Steve Rogers asked, the adrenaline wearing away and his mind catching up to his fight or flight instinct.

"No, we all saw that Capsicle." Tony Stark told him, his suit folding back up into the space around his arc reactor. And then he shot up to the sky, no suit in sight. "Oh, and I don't know what just happened, but I feel like I'm flying."

"You are flying, Tony."

"Nice!"
