Eve

Eve (イブ, Ibu) is the main antagonist in the Episode Yellow: Treasure de End Pirates.

Eve
He is an artificial Doberman Pinscher Imagin created by the G Men who is partnered to Reiji Kurosaki. He resides within a Rider Pass that resembles a badge, and as such, serves as the means of becoming G Den-O. Being an artificial Imagin, he has infinite knowledge and is able to counter any attack which he uses greatly even when he is not the one fighting. Like Kurosaki, Eve has little emotion, thinking only about duty and performing judgement. But when Kurosaki starts showing emotion, Eve deems humanity too illogical to exist and becomes G Den-O on his own, and deems his mission to be executing all humans. Eve (and G Den-O) were finally destroyed by Kamen Rider Diend Complete Form when Daiki used his Gekijouban Attack Ride Card and Final Attack Ride against Eve.

Equipment
Like other Den-O-like Riders, G Den-O uses equipment similar to Kamen Rider Den-O. It was destroyed along with Eve after he was defeated by Kamen Rider Diend Complete Form when Daiki used Gekijouban Attack Ride Card and Final Attack Ride against Eve.

G Den-O Belt
The G Den-O Belt is G Den-O's transformation belt, while styled differently, it has most of the same functions as the Den-O Belt. Other notable difference that G Den-O belt didn't announce anything when it is used to transform or when G Den-O using his Full Charge.

G DenGasher
The Combination Armament G DenGasher is G Den-O's primary weapon. It's only known formations are only two modes: Gun Mode and Jute Mode and is shaped differently than other DenGasher-esque weapons.

Full Charge
G Den-O's has two Full Charge attacks, when they are activated, Eve proclaims "Perfect Weapon!", shortly after. The first is World Punish, where a barrier encompasses G Den-O so he can attack with a series of shots from Gun Mode. The second one is World End, a powerful strike in Jutte Mode while the red and blue lights on his Den-Kamen light up but was not used in the movie.

Trivia

 * Eve is the only Imagin that does not have a monster appearance since he resides in a Rider Pass.
