==History==
Megahex was originally part of an unknown alien race which encountered the Helheim invasion. Being chosen to be the Man of the Beginning of his race, Megahex assimilated with its entire planet along with its inhabitants into a singular, mechanical being, with the planet itself becoming known as .
Megahex appeared on Planet of Helheim one day and attacked Kouta, as well as kidnapping Mai. During their fight on the planet, Megahex learned of the planet Earth from reading Kouta's memories and created a portal to Zawame with Kouta transforming into Gaim Kiwami Arms to stop him. But Megahex succeeded in reaching the planet as Gaim destroyed him with a a Burai Kick, only for the Kamen Rider to be defeated and destroyed by a second Megahex who then took the Kiwami Lockseed. When Takatora Kureshima demanded an explanation from Megahex, the being revealed his intend to assimilate Earth and began assimilating a section of Zawame and any unfortunate humans caught in the process. When Mitsuzane Kureshima stood in the way, Megahex used Kouta's memories to create Mecha Kurokages and then Mecha Ryoma Sengoku to drive Mitsuzane off.
The following day, as Takatora battled Mecha Ryoma, Mitsuzane stormed Megahex's ship as Ryugen, fighting through Plain Roidmudes (Lost Number) before saving Mai. As he did, Megahex appeared behind Zangetsu, who was weary from his fight with Kamen Rider Duke Dragon Energy Arms, and smacked the White Armored Rider to the ground before incorporating the Kiwami Lockseed into his system. Now boosted by the seed of the Golden Fruit, Megahex attacked Zangetsu with cold savagery, even using artificial Helheim vines spawned from his body until he knocked Takatora out of his transformation, landing near Mecha Ryoma's remains, chiefly near his Genesis Driver. Despite the beatdown, Takatora refused to give up, and when Megahex tried to cut Takatora down, Mitsuzane threw to Takatora the Melon Energy Lockseed. Thinking quickly, Takatora grabbed the Genesis Driver and lifted it up so the Melon Energy Lockseed inserted and locked itself into place, then slammed it on, generating the Zangetsu Shin Genetic Ride Wear to protect Takatora.
With a passionate speech, Takatora completed the transformation into Kamen Rider Zangetsu Shin, battering Megahex back with Ryugen's support despite being outmatched. As Takatora pulled a risky gambit to remove the Kiwami Lockseed from Megahex's body, the entity got furious of losing the item as he proceeded to obliterate the Kureshima brothers and Mai, but Kouta reconstituted himself while deflecting the attack. The three Kamen Riders proceeded to destroy Megahex, only to find more drones arriving as Megahex revealed that they had been fighting a few of a nigh-endless supply drone bodies which proceeded to scatter and commence total assimilation of planet Earth.
One of the Megahex drones landed near Shinnosuke and Kiriko upon notcing the deactivated husk of Cyberoid ZZZ's body after it was abandoned by Zoruku Tojo's consciousness. Megahex assimilated the Cyberoid and transformed into ZZZ Megahex, flying back to Zawame to distribute the upgrade to Planet Megahex. . Once arriving to Zawame, creating an army of Plain Roidmudes (Lost Number) and Mecha Inves with Kamen Rider Drive arriving after him, Megahex created a replica of Kaito Kumon to deal with the interlopers. But the copy proved too much like the original to obey Megahex, forcing the entity to fight Gaim and Drive. Though they countered ZZZ Megahex, his ability to regenerate made him a difficult opponent for the Kamen Riders until they received their Type Fruits and Drive Arms forms to destroy him.
The ZZZ Megahex data was transmitted to Planet Megahex as consequence, with Megahex creating several ZZZ Megahex drones with some combining into the Z Mega Bat to hold off Drive and Gaim when they used Tridoron after a Shift Fruits Tire Expansion to reach the planet's location, somewhere in between the Asteroid Belt and Jupiter. As they arrived near the core, the Z Mega Bat stood in front of them shooting missiles, and the walls closed in to attempt to crush Tridoron, prompting Drive to eject him and Gaim out of Tridoron, allowing them to perform a decisive Double Rider Kick to smash into Z Mega Bat towards the ground, followed closely by Tridoron crashing into it, allowing them to slam into the core, permanently destroying Megahex with all his creations shutting down.

*Megahex appears to possess his own language, as seen at the beginning of the Gaim portion of Movie War Full Throttle.
*Since Megahex's true core is located in its mechanical planet itself, it can be said that Megahex is essentially his own planet.
