The Hibiki gang. Love those guys. Considering it's a lot of new Riders for one movie (plus 3 from the TV show and the rest of Hibiki's massive cast) each one felt distinct in personality and as Riders. In a few seconds, I know what Nishiki or Kirameki are all about. Kabuki's also a step up from the usual bad Rider in that I can actually see where he's coming from. He's still siding with the wrong team, but there's a tragic element to it. Also, the theatrical cut of his end is better than the DC or the comic version.
After them, Femme.
