Raiden (prologue Raiden but he has his HF Blade from the main game) and Sam (DLC Sam, without the cyborg right arm and HF Murasama Blade), but they can't use Blade Mode. VS Dante (DmC Dante, he has Rebellion but not Ebony and Ivory) and Vergil (DmC Vergil from the DLC, he has Yamato), but they can't use Devil Trigger.
Who wins this 2 vs 2 battle? Battle takes place where Raiden fought Sam in "Badlands Showdown".
OG DMC Dante and Vergil will curbstomp Raiden and Sam. --- Most biased gaming article: http://www.gametrailers.com/side-mission/33395/league-of-legends- crowns-itself-most-played-video-game-in-the-world
