We get it: Sometimes the video game experience is enhanced through combining forces. That’s what Sony is banking on with the crossover-tastic PlayStation Move Heroes, featuring characters from their Ratchet & Clank, Jak & Daxter and Sly Cooper series. However, sometimes things can go mildly (or horribly) wrong by introducing new characters in a context that just doesn’t make sense. (It even happens to the best of them.) That's why we’ve put together our picks for the most nonsensical walk-ons in the history of video games, including a few surprises, a bit of a contradiction on our part, and even some chocolate starfish. Watch for the crossover!
