AN: Wow, it's been so long since I've written any Fanfiction! I was getting board of The Avengers, but then I saw Avengers Infinity War and regained inspiration.
So, how this story will work is each chapter will feature a different couple from the Avengers fandom. The chapters will not be related, and will take place between various movies, probably before Infinity War due to certain reasons that I won't mention (Spoilers!). If the story does take place after Infinity War, I will make that clear at the beginning of the chapter. Oh, also, these stories will just feature mildly romantic/suggestive dating activities, no bedroom scenes.
This chapter is about my favorite ship, FrostIron! It takes place in some vague, AU time period after The Avengers.
FrostIron
"Hey Lokes, have you seen the—"
PFFFFFFFFT!
Tony looks at the floor of the Stark Tower kitchen he had just entered and discovers a whoopie cushion under his foot… as well as a hundred other whoopie cushions completely lining the kitchen floor.
"Haha!" Loki says, casting his invisibility spell aside and revealing himself to be seated at the kitchen table.
Tony sighs. "Glad you're having fun Loki."
Loki frowns. "What is the matter, Tony? 'Tis just a prank."
"Yeah, I know," Tony replies, "but the board expects a new Iron Man suit by tomorrow, and I haven't even started on it yet." Tony tiredly stumbles over to the coffee maker, sighing again as his footsteps are accompanied by squelching.
"I know," Loki says. "I was trying to cheer you up, but I'm afraid I have just made things worse." He snaps his fingers, causing the whoopie cushions to disappear, then walks away with his head down.
"Hey," Tony says, rushing over to Loki. "Thanks for trying, really," he says, giving Loki a peck on the cheek when he still looks uncertain. "As soon as the suit's done, you'd better be on your toes for my prank!"
Loki smiles. "Very well."
…
Tony, being the genius that he is, manages to finish the suit in just a few hours. He looks at his Stark Phone and realizes it's only 4pm. Smirking, Tony goes back to "work", this time working on prank ideas for Loki….
…
Loki sits down in his favorite reading chair, leaning back slightly and crossing one foot over the other as he settles down to read. He had already finished one book today and was hoping Tony would be done with the suit by now, but fate had not allowed it to be so. After a few pages, Loki decides to head down to the lab to see how Tony is doing. He tries to stand up… and finds he is unable to! "What manner of magic is this?!" Loki exclaims.
"Only the finest of superglue," Tony teases, appearing from behind the curtains.
Loki shakes his head. "I would'st be angry, but this "super-glue" is quite ingenious. Might I study it?"
"Only if you promise not to use it on me," Tony replies, as he frees Loki from the glue-infused chair.
Loki rolls his eyes. "Do you think I, the god of mischief, would need to resort to your mortal pranks?"
"Hey! Watch it with the M-word," Tony says. "After all, I am a genius, so you just might lose this pranking contest."
Loki smirks. "A contest, you say? I shall surely win!"
…
The next day, Iron Man shows off his new suit to the board to much applause. He flies home cheerfully, and lands in his lab, only to discover all his other Iron Man suits have been bedazzled! They are covered in hot pink rhinestones, the color clashing horribly with the red of the suits.
"Hello dear, how did the meeting go?" Loki asks, casually leaning against the lab doorway like nothing out of the ordinary was going on.
"It went well, 'dear', now would you mind undoing this spell? Villains won't take me seriously looking like Lady Gaga made my suits."
"Ooh, I'm afraid I can't do that," Loki says. "I used the internet to learn more about superglue and discovered many other delightful Midgardian pranks. This one did not even require magic," Loki comments, holding up a bedazzler gun for Tony to see. "But I'm sure a genius like you can get them off in no time," Loki says, walking away as Tony gapes at him.
"Loki! Get back here!" Tony exclaims, but he knows it's useless. When Loki is determined to win a contest, he gives it 100% effort. Well, two can play at that game. "DUMM-E, U! Clean off those rhinestones. I have a boyfriend to prank!"
…
Later that day, Loki turns on the hot water preparing to take a nice, relaxing shower. Instead, he yelps as ice-cold water pours down on him! Loki quickly turns the water off, but upon looking in the mirror, he discovers the damage has already been done. His Jotun form is showing, his entire body covered in frigid blue skin with the demonic red eyes of his nightmares. Unable to stand the sight, Loki throws his cloths back on and opens the door, preparing to sprint back to his room and spend the rest of the day hiding there. Instead, a camera clicks.
"Ha! That's what you get for bedazzling my suits!" Tony says, staring at his cellphone. "I can't wait to see the look on your fa—" Tony frowns at his cellphone as the image finishes downloading. Confused, he looks up at Loki. His mouth opens. "Wh—" he begins, but Loki runs away before Tony can finish his thought.
"Loki, come back." Tony calls, as Loki barricades himself in his room. "That was a great magic trick."
"It was not a trick, it is my true form!" Loki wails, throwing himself on his bed in despair. He had never wanted Anthony to see this side of him. He felt terrible enough throwing Tony out of a window while under Thanos's mind control during the battle of New York, but this is no mind control. This is Loki's true self: a monster.
Tony is silent for a moment, then, "You look great, blueberry buns. Why didn't you show me sooner? Man, I can only imagine what Thor must look like with—"
"Do you think this a joke?!" Loki roars. "I am a Frost Giant, the most hated creature in the Nine Realms! The Allfather hath made it his mission to slay as many Frost Giants as possible! Why he would ever adopt one…" Loki falls silent. He had never meant to tell the truth. Lies are his specialty. The truth hurts. Loki waves his hand, causing a calm illusion of himself to appear over top of his tear-streaked face.
"Loki, open the door," Tony says.
Loki ignores him, instead snapping his fingers, which results in his suitcases packing themselves and appearing in his hands.
"Loki—"
"Are you quite done?" Loki says as he opens the door, sounding clam thanks to his glamor, while in reality, his voice cracks.
Tony frowns as he takes in Loki's human appearance and suitcases. "Loki, wait," Tony says, but Loki walks right past him towards the elevator. "Hey!" Tony yells physically blocking Loki's way. "I don't know what your idiot dad told you, but you're no monster. You're the cutest, funniest, most magically-talented alien guy I've ever met!"
"It is not just Odin's opinion, all of Asgard believes the same."
"Then all of Asgard is wrong!" Tony exclaims. "Just like everyone was wrong about me when they thought all I care about is partying and making money. I decided to stop making weapons the way my father did just because it's a good source of money, instead, I'm helping to make the world a better place. I don't know if these other Frost Giants are as bad as everyone says they are, but even if they are, it doesn't matter. You can be better than your parents. You already are.
"Tony," Loki sobs as his calm illusion fades away, his sharp-witted tongue for once at a loss for words. Before he knows it, Tony is hugging him, actually hugging him despite him being a Frost Giant. Seconds go by, then minutes, and still they are hugging. Loki doesn't want it to end, but then again, Tony is Tony….
"So, when you say 'frost', how cold are we talking?" Tony whispers into his ear. "I'm always up for trying new things in the bedroom, but if we're talking frostbite cold, I'd rather not freeze my d—"
"Tony!" Loki yells, cutting him off from that train of thought. He's not that angry though. After all, if Tony doesn't think his Jotun form is that big of a deal, then maybe it really isn't.
AN: So my headcannon is that Loki turns into his Jotun form whenever he gets cold enough that he is on the verge of frost bite, and that Asgard is a warm planet, so that never really happened there. Not sure if that's true or not. Also, the end of this chapter was somewhat inspired by Average Sized Slightly Cold Blue Creatures by NCSP.
