This year is going to be huge for superhero movies, with Batman and Spider-Man back on the big screen.
And the biggest team-up in cinema history also takes place in The Avengers Assemble.
Joe's been invited to meet the stars of the movie next week and he asked you to design your own superhero.
He'll take some of your pictures with him and will ask the real Captain America, Thor and The Hulk what they think!
He's now chosen the designs but we'll show as many others as we can over the week on the website and out television bulletins.
