Slapstick
Steve Harmon, a.k.a. Slapstick is a very unique character. He isn’t someone your mind would go to when thinking about the New Warriors, but he was a member for a while. He is a high school practical joker that accidentally got sent to an alternate reality while trying to save two classmates. This reality is home to cartoon creatures and just being in this world turns one into a cartoon. Steve can now turn into a cartoon-form. In said cartoon-form, He has all the powers associated with cartoon characters, including super strength, super durability and super agility. He also has a pocket dimension in his glove that allows him to access nearly anything. While Robbie is just a jovial character, Steve could be the super jokester of the team. With the success the Deadpool movie, I think this would be a good time for Marvel Studios to introduce their own goofy character with a sad clown complex.
