Kamen Rider 14
In one of the best jokes in the movie, Momotaros forces the others into helping him look for the Rider Pass. Yes, every time he just tosses it aside like that, he actually still has to go and find it after the battle. This time though, Daiki has found it first, and he's already on board the Den-Liner. As it turns out, he tricked everyone, allowing himself to get possessed by the Spider Imagin so that the Den-Liner would go back and he'd be able to take it over. If you think Daiki's plan is pretty crazy now, just you wait. Before the movie is over, you're going to find that Daiki is either a total genius, or the luckiest man in fiction.
