Tony:

Your nickname for Tony is Babe. When he asked you why you chose this name, you couldn't really respond. You didn't want to admit to him that it was because he was so damn sexy, because god knows that Tony needs another compliment going to his big head.

Tony's nickname for you is Sexy. Just because you refuse to call him sexy doesn't mean that he refuses to call you it! Tony loves every part of you, and whenever you're feeling down, he always wants to know how amazingly perfect and sexy you truly are.

Steve:

Your nickname for Steve is Honey. It's such a sweet little lovebird name, and whenever you call him Honey, you always tell him that he's even sweeter than his nickname. When you're in a jokey mood, though, you'll call him Old Man. He really hates that name, but in a fun way.

Steve's nickname for you is Sweetheart. This goes along with your little sweet theme. Whenever you tell Steve that he's sweeter than honey, he'll reply with, "Not as sweet as you, Sweetheart." When you call him Old Man, he'll joke back and call you a Whippersnapper then go on and on about stories of the "good ol' days".

Clint:

Your nickname for Clint is Hotshot. Your reasoning for this is that: 1. He's hot & 2. He shoots arrows, so shot. He rolls his eye every time you use it, but you notice his confidence boost every time you use the nickname.

Clint's nickname for you is Beautiful. He always compliments you on the way you look, saying, "I not only have the most brilliant girlfriend, but also the most beautiful." This always receives a bright red blush from you, which makes him smile even more.

Thor:

Your nickname for Thor is Blondie. Whenever he's being over-dramatic or gives you a really kind compliment you always come back with "Chill out, Blondie." This of course is in reference to his luscious blond hair that you love so much.

Thor calls you My Queen. Considering that one day Thor could become King of Asgard, he tells you day after day that you'll most definitely be his queen if the day should come, hence the nickname.

Bruce:

You like to call Bruce Mr. Smartypants. He always seems to ruin romantic moments with a fact about health, or with him running off to science. You don't mind as much as you make it seem like you mind, but you still love teasing him with the nickname.

Bruce will call sometimes call you Darling. As a kid (and now), you've always loved the Peter Pan movies, making Bruce watch them thousands of times. Since you're quite a darling person yourself, Bruce gave you the nickname of the Darlings in honor of Peter Pan himself.

Loki:

Loki loves it when you call him your King. It makes him feel so strong and powerful, as if he could take on the world (not that you'd let him!!!). He may never get to be King of Asgard, but it really helps him out knowing that he's a king in your eyes.

Loki will call you Goddess, as he claims "Nobody from Earth could be so righteous and good-looking. You must be a goddess, (Y/N). You must be." You aren't sure you believe 100% of the statement, but it still is a really cute nickname.
