Eubulon, known as the "Advent Master", is the creator of the Kamen Riders and comes from the Planet Karsh. He once worked with General Xaviax in the planets North army by developing weapons for him in their war against the South.
Although the North won, Karsh was turned into a waste land and Eubulon was enlisted by Xaviax to create a transportation device that would send a mass amount of people from other planets as slaves to rebuild their world, starting with Ventara. When he arrived, he fell ill and almost died. He was taken in by a Ventaran family who helped him recover and this helped him realize that he couldn't enslave a peaceful planet. He soon told Xaviax that he wouldn't take the Ventarans and that they would have to find another way to save Karsh. Unfortunately, the general refused to listen, leading him to think that Eubulon had committed treason and with this he decided to enslave the people of Ventara Himself. Eubulon warned The Planet's leaders of what was coming and then created the Kamen Riders to stop Xaviax, while the Ventarans selected twelve of their very best to take up the mantle.

Eubulon also created an advent deck and powers just for himself and has the ability to change the DNA sequence of the other Rider Decks so anyone can use them. He fought Xaviax to a draw and ended up being found on Earth in Roswell, New Mexico. He warned the No-men of Xaviax upon his arrival but he was injured badly and unable to tell them anything else.
Reawakening
60 years later, Len was brought in to reactivate Eubulon. Len had informed him about Adam's betrayal and of Xaviax's activities. With Xaviax on the move, he reassigns the Siren deck to Maya as she helps Len stall Xaviax as Eubulon goes to retrieve the Riders in the Advent Void. He manages to bring the Ventaran Torque, Strike and Axe (Chance, Pryce, and Hunt respectively) as he and Len explain their current situation to them. He gives them a device that will upload a virus into Xaviax's transportation devices as they will need all of them to retrieve the people of Ventara. Eubulon goes back to the Advent Void to retrieve other Riders, including Kase and Kit. When he brings them out of the Advent Void, he gives Kit the Onyx deck to help out Len, Chance, and Price. After returning to the No-Men's base, he begins repairing the key in order for it to fully function again, before sensing Maya in danger and sending Kit to assist her.
Abilities
Either through natural or technological means, he is capable of projecting a human disguise over his true Karshan form, and does so most of the time. He is also shown to form an energy ball in his hands that puts Hunt into a healing trance after he is injured; if this ability is natural or technological is also unstated. Like Xaviax, he can summon and control mirror links to and from Ventara with a wave of his hand.
Eubulon, being the creator of the Kamen Riders, has the ability to manipulate the Riders' arsenal. He can change the DNA lock each Deck has and reassign it to other people if necessary. He also has the key to the Advent Void, which he created as a fail-safe to prevent any Rider from getting killed in action, taking them out of the battle if they are too injured. While the key was damaged with his fight against Xaviax, it still functions well thus making any future vents a non-issue, but as it was damaged, he had to begin repairing it after retrieving only a small handful of Riders.
If he ever needs to defend himself, he can use the key as an Advent Deck to transform into his Rider armor; when used as a Deck, it uses a different card slot format than the others. With his reappearance, the war against Xaviax has changed from a fight for survival to a fight against time. He also creates a new Advent Card called Link Vent and gives it to all 13 Riders. This card, which design looks like Strike's Unite Vent, combines the power of all 13 Final Vents and unleashes it into one condensed attack. This card was specifically made to destroy Xaviax as he had proven to be more powerful than expected.
