Taiga Nobori (Prime Reality)

"The King's sentence is given. It's death!"

- Taiga's words to punish the Fangires who have done something he hates most.

Taiga Nobori (登 太牙) was the King of the Fangires and is Kamen Rider Saga (仮面ライダーサガ). He later became Kamen Rider Dark Kiva (仮面ライダーダークキバ). Initially the fiance of Mio Suzuki, he learns that she becomes willing to abandon her Fangire heritage and her future as Queen of the Fangires to be together with his half-brother, Wataru Kurenai, resulting in conflicts between reunited brothers.

Overview
Taiga was born prior to 1986 as the first born son of Maya, the Queen of the Checkmate Four, and the Checkmate Four's original King. He would receive the title of King at infancy after his father's death before he was spirited away by Maya to be raised by Mamoru Shima as a human child, wearing a glove over his hand to conceal his Checkmate Four crest. It would be while as a boy that he encounters Wataru Kurenai and the two become good friends until Taiga was spirited off, his childhood being under heavy watch.

Though his Fangire form is a mystery, he displays impressive powers such as summoning a giant shadowy mass of vipers or conjuring up the called Kukulkan (ククルカン) and multiple giant Sagarc under a larger Mother Sagarc (マザーサガーク) as his support.
