Let's Go Kamen Riders
Due to a change in history caused by Ankh leaving an O Medal behind in the year 1971, Shocker achieved its goal of world dominion with the Shocker Greeed and new members from the various groups joined an alliance under Shocker's control. Apollo Geist, King Dark and the Government of Darkness were part of Shocker's alliance. He was never killed by X, not needing the Perfecter to sustain himself even years into the future. When the timeline was partially restored and the Riders returned, he tried to face X, only to be defeated. He was only destroyed, however, when the Great Leader became the Great Rock Leader and spread destruction around the world.

This Apollo Geist used a modified version of the design of Decade's version, having the Perfecter removed, and also the actor of that same version voiced him, however, his official bio[1] makes it clear that he's the original character, rather than Decade's version.

Kamen Rider Decade
The first member of Dai-Shocker that Tsukasa confronts, Apollo Geist is the Security Chief of Dai-Shocker, hastening the worlds' convergence to make invasion easy for his organization. He normally assumes the form of a man called Guy until he invokes "Apollo Change"

Originally from the World of X-Rider he was revived by the Government Of Darkness after being killed by X-Rider. However, his lifespan is short as a result and thus uses the Perfecter to take the life force out of people to augment his own.

When the Perfecter is stolen from him by Diend RX! Dai-Shocker Attack/Black × Black RX and then destroyed by Decade, Amazon, Friend/The Strong, Naked, Strong Guy Apollo Geist eventually comes up with the plan to marry Yuki, the Fangire Queen, becoming a Fangire as a result. As a result of his transformation, he now becomes Super Apollo Geist with the ability to remove other realities from existence. Rider War: Prologue Using his power to revive the monsters from the Nine Worlds and attempting to make Natsumi his bride after Yuki is destroyed by Decade Complete Form, Super Apollo Geist fights Decade and Diend until help arrives in the form of Hibiki and Kiva. Kiva and Hibiki distract Super Apollo Geist long enough for him to be mortally wounded by Decade Complete Form with Diend's power, Geist swearing that he will "revive as the greatest nuisance in the universe" before he is destroyed.

Super Hero Taisen
Apollo Geist was later revived as part of Dai-Shocker, led again by Tsukasa as Great Leader. Dai-Shocker were now fighting Dai-Zangyack and the Super Sentai teams, but Tsukasa was overthrown by Doktor G who joined forces with Dai-Zangyack. Apollo Geist was part of the combined forces of Dai-Shocker and Dai-Zangyack when they engaged the Kamen Riders and Super Sentai. Apollo Geist fought Kamen Rider Fourze, who assumed Magnet States to destroy him.
