This article is about a/an villain in Kamen Rider X.
For the A.R. World version, see Guy.

Apollo Geist (アポロガイスト Aporo Gaisuto, 8-14) was the Chief of Security of G.O.D., assigned to execute any member of the organization no longer of use. Initally appearing as a man wearing a white tuxedo with black gloves until he invokes "Apollo Change" (アポロチェンジ Aporo Chenji), Apollo Geist's true form is an armored cyborg.

First destroyed following a failed attempt to take out X-Rider by shaking his explosive hand after he was defeated by X's X Finishing Kick, his husk was reconstructed at the Apollon Palace by two G.O.D. scientists and he became Revived Apollo Geist (再生アポロガイスト Saisei Aporo Gaisuto, 16-21). As a final resort, he assumed the form of a giant fireball but was ultimately destroyed by X's X Kick.

Character History



Let's Go Kamen Riders

Let'sGoKamenRiders Apollogeist

Apollo Geist in 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.
