This is how you do it folks. All you need are friends that fall within a very specific range of heights—and the tallest guy needs to be like 7-foot. That isn’t easy of course, but great cosplay never is.
Even this brilliant cosplay isn’t perfect. For one thing, the little Ant-Man should be holding an Ant-Man action figure, preferably the sixth scale Hot Toys version. And Ant-Man #2 (from left to right) should be a few inches shorter because he’s throwing off the symmetry.
