Danketto appears to be at least partly insectoid with a large, fly-like head and strange claws for hands. Its skin is blue with diagonal crimson stripes.
The Magic of the Boy Flasher!!
Danketto was the twenty fifth monster to battle Greenman. Him and Tonchiki went to seek out the children for Maoh, and in the children's panic, they used their Green Calls. Greenman was then summoned, and Danketto fought with him. They had a short scuffle, and Danketto grew. To continue the fight, Greenman grew too. They fought on a hill which proved to be a challenge for Greenman. For example, Greenman attempted to do a cartwheel towards Danketto, but slipped. This left Greenman open for an attack, and Danketto beat on him. Eventually, Greenman managed to defeat the monster.
- In Go! Greenman, Danketto had multiple tongue-shaped explosives lodged in his chest which he could summon to his mouth for use in battle. However, he only has a certain amount and once out, must wait for more to generate.
- In Danketto's debut appearance, episode 8 of Assault! Human, his body's colors were much more vibrant and he possessed large wings. However, most likely due to suit deterioration, Danketto's body was much more dull and his wings were removed in Go! Greenman.
