Avengers — Christmas

Christmas was, without question, the best time of the year. At least, that's what you believed. Sure, some people insisted otherwise—Loki being the loudest—but one look at him laughing after absolutely nailing Thor with a snowball said enough. He secretly loved it. Sibling rivalry just came wrapped in tinsel.
Outside, snow blanketed the city and the trees, while cheesy Christmas carols drifted through every street—and, thanks to Peter Parker, echoed through Avengers Headquarters too. After enough complaints, Quill had finally been banned from hijacking the speakers with his "classics."
The common room buzzed with life around the enormous Christmas tree Tony had proudly dragged in. Outside sat two battered snowmen: an Iron Man one Peter, Tony, and Morgan had built before it was crushed, and another whose head had been half-knocked off—almost certainly Rocket's fault, with Groot as an accomplice.
Board games had descended into chaos. Carol accused Thor of cheating, Loki threatened to turn him into a frog, Peter sprinted through the room with Clint's kids and Morgan chasing after him, while Tony seriously pitched Rhodey a Christmas-themed Iron Man upgrade. Drax questioned why "Santa" broke into houses, Steve reminisced about Christmas in the '40s, and Sam and Yelena mocked the overly cheesy holiday movie playing on TV.
Meanwhile, tucked away in the kitchen, you and Wanda baked cookies, somehow managing to cover nearly every surface—and yourselves—in flour. Every few minutes you had to swat Bucky's hand away from the cooling tray, while Natasha watched safely from a stool after being firmly banned from helping. No one trusted her near a kitchen, and for good reason.
