#6 Captain America (Iced)

Captain America: The First Avengers was the best Avengers-universe movie to hit the silver screen. It wasn't as boring like Thor, cocky like Iron Man, or unintelligent like the Avengers. For aquariums, Captain America on ice definitely a conversation piece that will make the other nerds bow down to your superiority.

From wikipedia:
"In 1940, writer Joe Simon conceived the idea for Captain America and made a sketch of the character in costume. "I wrote the name 'Super American' at the bottom of the page," Simon said in his autobiography. "No, it didn't work. There were too many 'Supers' around. 'Captain America' had a good sound to it. There weren't a lot of captains in comics. It was as easy as that. The boy companion was simply named Bucky, after my friend Bucky Pierson, a star on our high school basketball team."
