History (Pre High School Days)Edit

High School DaysEdit


Kengo is a loner with a strong will and wants to follow through with his father's plans to fight. Because of this, he tries remains distant from people to not get them involved. Kengo does however accept help from the other Riders, Gokaigers, the Power Rangers, and Gentaro after some convincing.

He is willing to go to lengths that puts him and his health in danger which limits his actions. Though he is Gentaro's partner, he insists that Gentaro refers to him by his surname instead of his given name, and much to his chagrin, Gentaro refuses to do so.


Kengo has short brown hair and light blue eyes, wearing the standard school boys' uniform and rather plain simple clothes when not at school.


  • Kengo's name is based on Takeshi Hongo, Sakura's original counterpart, as part of Fourze being the Riders' 40 Anniversary.
  • Like Ankh, while not a Rider himself, Kengo being chosen by Zordon is reference to him being the lead supporting protagonist in the series.
