Gakko and other Fingers of Poison were formed by Camille to destroy the Jungle Fury Rangers. In the first battle with rangers Gakko fought with Casey. After Rantipede was defeated Gakko decided to fight the rangers. Gakko was master of gecko fight style. He had all powers of gecko such as regrowing limbs and sticking the walls. He could climb the walls and throw energy bombs. Gakko also thought that all great warriors cpuld fight only at the side of the wall. Gakko attacked Ocean Bluff. He attacked people un the building and encountered the rangers. Gakko climbed the wall and rangers couldn't fight him. Gakko fought with Theo. Gakko left. Dai Shi ordered Gakko to destroy the rangers next time he battle them. Gakko attacked tue city with Camille and Rinshi. In the second battle Gakko fought only with Casey and Lily. But then Theo arrrived and defeated Gakko using his skills of balancing on the wall. He defeated Gakko and threw him down. Gakko enlarged himself. In the giant battle Gakko separated his arm and it caught Jungle Pride Megazord. But rangers freed themselves. Just like Rantipede Gakko was destroyed by Megazord's 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 and become stronger. But rangers arrived and after the battle Gakko was destroyed by Claw Cannon.
In the final battle Gakko was revived by Dai Shi but was finally destroyed by RJ.
