Kougane

"I am the God of the New Generation!"

- Kougane telling Kouta who he is

Kougane (コウガネ), or Kogane in different publications, is Kamen Rider Mars (仮面ライダーマルス), who is the main antagonist in Kamen Rider Gaim: The Great Soccer Match! The Golden Fruit Cup!.

History
Kougane is the manifestation of the Golden Apple created by the Over Lords in the past. When an experiment by Ryoma goes wrong, Kougane awakens and kills Ryoma. Kougane's existence causes the Armored Riders to lust after each other for the "Golden Fruit". Slowly, the Armored Riders start to kill each other off as Kougane masquerades as Yuya to get to Kouta. When it is revealed that he is not Yuya, Kougane transforms into Armored Rider Mars and defeats Kouta. Corrupting Kouta into Kouta-Yami, the two go after Lapis. However, Ryugen, Baron, and Marika interfere, with Lapis disrupting the mind control on Kouta. Kouta transforms into Gaim Kachidoki Arms and chases Mars in a fight that ultimately allows most of the deceased Riders, whose heart was not fully corrupted like Sigurd and Duke, to return to aid Kouta. Mars emerges with a flaming horse and is defeated by the Armored Riders as the world returns back to normal, also resulting in Lapis' disappearance.
