The Gekirangers are practitioners of the Fierce Beast-Fist Beast-Art style of Kung-Fu, which allows them to summon incredible power through a unique brand of Ki energy powered by the desire to fight selflessly called Geki. The style is separated into three variations pertaining to the Body, Heart, and Mind of the user.
Ken doesn't possess as much Geki as the other Gekirangers; though he was able to master the rare Fierce Beast Rhinocerous-Fist style, considered one of the oldest Beast Arts. What sets Ken apart from the others is his Fierce Ki Hard Diamond Technique, which hardens his Ki into a diamond-like hand-blade that can cut through nearly anything.
