Deneb is an Imagin fully contracted to Yuto Sakurai and aids him as Kamen Rider Zeronos both in and outside battles.

Biography
Acting against Kai, Deneb formed a contract with Sakurai, gaining a physical form within normal space-time due to Sakurai's wish to have the Imagin aid his past self Yuto. Aiding Yuto and Sakurai, Deneb aided them in keeping Kai distracted from learning of his actual target. But when Ryotaro began to realize Sakurai's presence in the past, Yuto and Deneb reveal themselves to discourage the youth from ruining their distraction.

He also acts as a parental figure to Yuto, doing his best to make sure he lives healthy, including a need to serve shiitake to him, despite Yuto's deep hatred towards it (and usually resulting in a comical beating). Due to the fact he has a physical form in normal space-time, Deneb often appears in (poorly constructed) disguises in order to avoid standing out. At one point, Deneb accidentally caused Yuto to waste his second to last ticket. He decided to stop being a burden to Yuto and offers his services to Ryotaro, but it took Ryotaro and Momotaros' words to convince him to return to Yuto.

After Yuto uses his final card, Deneb feels at ease that Yuto wouldn't need to suffer the side effects anymore. That was until Sakurai comes with a new Zeronos Card and a full card holder. Deneb drives the man out with intent not to have Yuto suffer again, but is forced to allow Yuto to use them when he wants to. While Yuto is negated from time momentarily, history is rewritten such that Deneb is contracted to Ryotaro, but is confined in the Den-Liner like the Tarōs, during which he serves as the cook and takes Hana's position in keeping the Tarōs in line (with a noticeably more gentle approach).

When Yuto returns and assumes Zero Form, Deneb is alongside him as the Denebick Buster, to which he finds to be a surprise. However, when he finds out that he completely forgot about Yuto when he was erased from time, he is horrified and breaks down in tears. Deneb decides to make sure no one forgets Yuto by possessing him at night and passing out Deneb Candy to passers-by. However, Deneb learns the hard way that his actions do more harm than good when a young girl he befriends ends up inadvertently creating a contract with an Imagin.

Since then, Deneb pledges to Yuto that regardless of the circumstances, he will fight alongside him until the very end. But when the time does come, it turns out his adventure with Yuto created a time lag, allowing him to maintain his existence as he takes leave in the Zero-Liner, returning to aid the Den-Liner crew during the events of "Final Countdown" before a fully healed Yuto joins it. Deneb then returns with Yuto to investigate Negataros by posing as crooks themselves. Soon after, Deneb tries to get Yuto and himself to join the Den-Liner Police.

Personality and Abilities
Being the opposite of Yuto, Deneb serves as his butler and comrade in battle. Though his intentions are noble, Deneb usually causes embarrassing consequences for Yuto, who comically beats him up for it. Although Yuto treats him with occasional disrespect; Deneb chooses to stand by his side out of friendship and loyalty, knowing Yuto to be a kind person. Due to the fact he has a physical form in normal space-time, Deneb often appears in (poorly constructed) disguises in order to avoid standing out. He carries around a basket that contains hand-made candies that have wrappers that bear his face called "Deneb Candy" (デネブキャンディー), which are made from milk, honey, and sweet melon. In a fight, Deneb is able to shoot bullets out of his fingertips that range from attacking an enemy to smoke pellets.

Due to Deneb's limited interaction with the Tarōs, he does not have names for them. However, he has on one occasion called Kintaros "Kumataros" (クマタロス) and Urataros as "Kametaros" (カメタロス). Deneb is also the only Imagin other than Ryutaros to call Momotaros by his actual name as opposed to a nickname.

Zeronos
Vega Form (ベガフォーム) is the form of Zeronos that comes from being possessed by the Imagin Deneb. It is named after the star Vega in the constellation Lyra the Lyre. It has a series of cannons on its shoulders called the Zeronos Nova (ゼロノスノヴァ). In the process of transforming into Vega Form, Deneb's body makes up various aspects of the form: his face is on Vega Form's chest, his hands form the Zeronos Nova, and his cloak becomes the cape. The "mask" is made up of a spool of thread, as Vega is a weaver, that opens up into a star shape. Vega Form is physically stronger than Altair Form, although suffers a loss of speed and overall agility. Whenever Deneb possesses Yuto to assume Vega Form, he says "I'll tell you this for starters…" (最初に言っておく…), following with a honest fact that annoys both the opponent and Yuto. Vega Form is accessed for the last time during the final battle, playing a part in the destruction of the Death Imagin, although Yuto assumes the form once more in the fight against Negataros.

New Den-O
Vega Form (ベガフォーム) is the form of New Den-O that first appears in The Onigashima Battleship. Kotaro allows Deneb to possess him and use his abilities, his Denkamen made up of a spool of thread much like Zeronos' Vega Form, and his armor also has Deneb's face on the torso. The only difference from Zeronos' Vega Form is that his suit is colored dark blue and instead of the Zeronos Belt, he has the NEW Den-O Belt. In this state, New Den-O can use his DenGasher in Naginata Mode (ナギナタモード). This form is assumed automatically following Deneb's possession of Kotaro, due to having no corresponding button featured on the NEW Den-O Belt.

Denebick Buster
"Full Charge!"

- Finisher announcement via Zeronos Belt

The Denebick Buster (デネビックバスター) is a weapon that Deneb is able to transform into when Zeronos is in Zero Form. The sides of the barrel have gold-colored versions of the Zeronos Nova attached to Deneb's face. Deneb can talk through this form. The barrel and the blade of the ZeroGasher Crossbow Mode can be interchanged, allowing Zero Form to dual-wield guns.
