Kamen Rider Kuuga
When his turn came, Ginoga began killing two people by poisoning them with spores. However, he was forced to flee when the police show up and shoot him with Modified Bullets.
After facing off against the entire police force, Ginoga was attacked by Kuuga in Growing Form with support from the police supporting him. Ginoga was killed by Kuuga with a stronger form of his Growing Kick. However, Ginoga's arm remained and regenerated into a mindless mutant (変異体, Hen'itai) version of Ginoga.
Kuuga went to fight the mutant Gurongi in Mighty Form and used his Mighty Kick to disrupt the Mutant's cellular structure, causing it to dissolve into a puddle of ooze, finishing off Ginoga.
Kamen Rider Decade
Me-Ginoga-De was part of a group of humans who were turned into Gurongi by N-Gamio-Zeda. Some were later absorbed by him in attempt to power him up to defeat Kuuga and Decade while the rest died after Gamio was defeated.
All Riders vs. Dai-Shocker
Me-Ginoga-De was among the revived monsters who were a part of the Dai-Shocker army in the World of Decade that fought against a gathering of the 25 Kamen Riders.
Powers and Abilities
Ginoga was capable of infecting people with poison spores, either by kissing them or with a spore cloud. He was also capable of regenerating, even from only a limb.
