|“||Master of trickery and deceit. Gakko!||„|
|~ Gakko's roll call|
|“||Why won't they lose?||„|
|~ Gakko's last words before his death.|
Gakko is a minor villain in Power Rangers Jungle Fury. He is one of the Five Fingers of Poison, possessing the spirit of the gecko and can detach his limbs, then regenerate them, as well as stick to walls.
Gakko and the other four Fingers of Poison were called up by Camille to destroy the Jungle Fury Rangers. In the first battle with the Rangers, Gakko fought with Casey.
After Rantipede's defeat, he laughed at the centipede warrior's failure and said he could destroy all the ranger's himself. Camille gave Gakko the order to do so and he battled the rangers, eventually taking to the side of a building and challenged the rangers to fight him there. He swatted Casey and Theo, the Blue Ranger, away when they tried to attack him, taking away Theo's confidence, and left. Dai Shi ordered Gakko to go back and finish the job, so the gecko warrior went back with Camille and a host of Rinshi. Casey and Lily arrived, successfully fighting off the Rinshi, though with difficulty and were barely able to fight Gakko and Camille. Gakko took to the side of a building again but Theo showed up, having regained his confidence with training from RJ. He beat Gakko at his own game, forcing him back onto the ground and he grew to giant size, only to meet the same defeat as Rantipede which is a Savage Spin.
Later, Gakko, along with Rantipede, was revived by Naja to help him overthrow Dai Shi. But he fled as during the battle Rantipede was destroyed by their vengeful master. Gakko went to the city and started to absorb fear of people to become stronger. But the Rangers arrived and, after a battle, Gakko was destroyed again, this time by the Claw Cannon.
In the final battle, Gakko was revived by Dai Shi but was finally destroyed by RJ.
