Kamagidon's upper half somewhat resembles an insect or arachnid. Its head is adorned with multiple jagged spines, short mandibles, and a single blue eye. Instead of hands, Kamagidon possesses large electrically conductive sickles at the ends of its appendages. Also, rather than legs, Kamagidon's upper half is attached to what resembles a Stegosaurus but with a larger, horned head similar to that of a Triceratops.
After Takeshi Shishido and his mother Rosemary fled to Earth from the planet Rosetta, Captain Dagger deployed Kamagidon to attack Tokyo in order to draw Megaloman out. Takeshi transformed into Megaloman for the first time and fought Kamagidon, eventually coming out victorious despite multiple close calls.
- Kamagidon has scythes instead of forearms.
- These scythes can fire missiles when clapped together.
- When electricity is absorbed by them, the scythes can be electrically charged. This also causes explosions on contact.
- The lower section of Kamagidon has more strength then its top half.
