Gamma Ultima

Gamma Ultima (眼魔ウルティマ) is a title used by the Royal Gamma Family or Gamma Superiors that promoted to such status by said family.

History
Xibalba was the first Gamma Ultima encountered by the Kamen Riders Ghost and Specter. The twins Frey and Freya arranged for the Kamen Riders to gather the Rider Eyecons to defeat Xibalba but were absorbed by him, granting him the upgraded Gamma Ultima Fire form. Ultimately, the two Kamen Riders were able to wear down Xibalba to his original form through the three Rider Damashii they both accessed each before destroying him with the combined power of the Rider spirits, freeing the twins.

In the world of Gamma, Takeru and Makoto encountered the prince Adel, who used a Gamma Transformation Eyecon to assume the form of Gamma Ultima, proving to be a near-unstoppable opponent capable of dissolving their weapons with a single touch. The Kamen Riders were barely able to survive his attack, only managing to escape due to Specter Tutankhamun Damashii's Omega Fang temporarily holding the Gamma Ultima back. Following this, Adel would give his Transformation Eyecon to Jabel, who he awakened in his true body. Sending him to kill Alain, who was left reduced to his flesh body as well after Adel destroyed his Gamma Eyecon, Jabel attacked the banished prince, easily overwhelming both Necrom and Specter while Takeru hesitated to defeat Alain. Eventually, after Makoto's Gamma body was destroyed by Jabel to protect Alain, Takeru engaged the Gamma Ultima and, once the 15 heroic spirits saw his resolve and elected to combine their powers, Takeru used the Eyecon Driver G to assume Grateful Damashii. Overwhelmed by Grateful Damashii, Jabel was unable to resist even after a pillar from the Gamma prayer chamber granted him the form of Gamma Ultima Fire and temporarily overode his free will. Ultimately, the Gamma Ultima form was destroyed by Grateful Damashii's Omega Drive utilizing the combined power of the 15 Parka Ghosts, and Jabel barely escaped with his life.

Gamma Eyecon
The Gamma Ultima form is accessed via the Gamma Ultima Eyecon.
