It was hard to choose between Black Widow, Hawkeye, Captain America. I voted Captain America in the end because I must admit I am a huge Captain America fangirl. I may be a rifle person (I'm a target shooter) but I seriously love and want Hawkeye's bow. I have to say I like Hawkeye because he's good looking and not so much for his character. As for Black Widow, she's got some kickass moves, an interesting backstory and I must admit she's pretty good looking.
I also loved Loki in the film, Tom has Loki's character down to a tee an I was really impressed with the acting. I was a Loki fangirl when Thor came out and the Avengers movie made me love him even more.
