Kira Hayama (破山キラ Hayama Kira) is the main antagonist of Beyblade: Shogun Steel. He is the fearsome wielder of the Gladiator of Destruction Bey, Gladiator Bahamut SP230GF, which is a replacement Bey for the Dragon-Killer Bey, Berserker Behemoth SR200BWD. A DNA activist, Kira along with Yoshio Iwayama were sent by their bosses in the form of Team Garcias of DNA to foreshadow the events of Neo Battle Bladers. Brutal and quite hellacious of a Blader, he is among the most powerful of Bladers DNA has to offer with their project, Evil Gene.
