Dwayne Winfield (Henry)


 * Not to be confused with Henry Winfield, Ryotaro's grandson, who became New Den-O

Henry is the eleven-year old version of Dwayne Winfield that he met during the events of Kamen Rider Den-O: I'm Born!, nicknamed Kotaro to differentiate him from his present, older self.

I'm Born
When Dwayne and Hana are trapped in the year 2000 by Kamen Rider Gaoh they encounter Ryotaro's child self. With Ryotaro lacking memories of being Kamen Rider Den-O due to being attacked by Gaoh and unable to transform, the young Dwayne is given the nickname Henry and decides to go with them to stop Gaoh's plans. During a fight with ninjas in the Edo Period, Momotaros possesses him with his contract to Dwayne extending to the past and transforms into Kamen Rider Mini Den-O.

After the battle Henry is brought back to his time but not before seeing his late parents and then bids the gang farewell.

Sword Form
A form assumed when Momotaros possessed Kotaro during a fight between some of the ninja in the Edo period during Kamen Rider Den-O: I'm Born!

Onigashima
As a result of an unknown force altering the present Dwayne is regressed into an adolescent form. While investigating an error in time with Deneb and Kamen Rider New Den-O he encounters a child Yuto Sakurai. Later after finding three of the scattered Tarōs and going into the time of the battle against Oni Island Ryotaro reunites with Momotaros and fights alongside everyone.

Despite being a child, Dwayne does not assume Mini Den-O, instead becoming an adult Den-O. This is possibly because unlike Kohana who was regressed into a child due to her future being recreated, Dwayne was de-aged as a result of an unknown tampering of time.
