kamen rider kuuga (super rising ultimate form)
Super Rising Ultimate is an even further evolution of kamen_rider_kuuga_(rising_ultimate_form), accessed by Yusuke Onodera and exclusive to the S.I.C. Hero Saga.
This form is attained after Kuuga is infused with electrical power from Kamen Rider Stronger and Kamen Rider OOO Shauta Combo's Unagi Whip. In this form, Kuuga's entire body, including the eyes and Amadam, turn gold in colour as a result of this super evolution. As this form is an upgrade of Rising Ultimate form, Kuuga supposedly surpasses almost every single Kamen Rider in this form and can be considered one of the strongest and most powerful Kamen Riders in existence.
