Spoopy
(Sorry this is late; it's coming out the day after Halloween, I know, but it's been a busy couple days, I haven't had much time to write. I'll try to put Steve's wedding preference out later today)
Tony
You went as Danny and Sandy from Grease. At the end of the movie, of course.
Steve
You were Mickey and Minnie Mouse, of course!
Thor
You never were one for Halloween. You stayed at home and handed out candy with him instead of going to a party or anything like that.
Bruce
You were Alan Rickman and Sigourney Weaver in Galaxy Quest. The amount of people who thought you were dressed as Star Trek people... ugh...
Clint
You were Khal Drogo and Khaleesi from Game of Thrones. You had worked on your costume for a while, he just dressed up a kilt from his high school days, painted his chest, and threw on a wig. Both of you looked pretty good, despite Clint being white and Khal being Dothraki.
(I've never seen nor read Game of Thrones, sorry if I butchered anything)
Natasha
You went as Liz Lemon from 30 Rock, and she was Leslie Knope from Parks and Recreation. Interestingly enough, she had a perfect Leslie Knope impression. Everything from the talk to how excited she gets when she talks about Ann Perkins, which was also the name of a new SHIELD Agent.
Bucky
You were Ellie and Carl in Up. It took some convincing, but after he watched the movie again, he was fanatic to do this.
Pietro
You went as Roger and Jessica Rabbit. He looked adorable in those little suspenders, and he greatly appreciated your dress.
Wanda
You love Halloween, so you made sure that you and Wanda would have the best costumes out there... and you think you succeeded. You were Cinderella and she was Belle... it was incredible.
T'Challa
Wakanda didn't really celebrate Halloween, so you didn't participate.
Peter
You went as Spider-Man (he got a new costume meant to be a costume so nobody would suspect) and Spider-Gwen, which was some chick who helped him out sometimes. You thought it was a hilarious idea and it was hilarious when people laughed at Peter for wearing the costume of someone so "different" from him.
Sam
You two weren't big on Halloween, you'd rather stay home and play horror games (fun ones like Bendy And the Ink Machine) and watch Halloween movies like Hocus Pocus. You barely dressed up, but took any opportunity to wear matching clothes.
Rhodey
Rhodey hates Halloween. He doesn't say why, but he just does. You go to parties alone or with him dressed as "Her boyfriend". You went for comfort, but still had fun with it.
Scott
You actually don't like Halloween. You stay at home while he goes off and does his thing... you really wish he didn't do his thing.
Loki
You do Halloween together every year since he was freed. He was Peter Pan, you were Wendy.
Zemo
You loved going to Halloween parties, and you would always go with Helmut as Mary Poppins, an American Disney movie character, and he would go as her love interest: Bert, the chimney sweep.
