Kumonga can shoot a thick webbing and a stinger from his mouth. He is also a great jumper. Kumonga has prehensile pedipalps that can be used to grab small prey. The Showa version was able to survive multiple hits from Godzilla's atomic ray. The Millennium Kumonga's web was able to expand on contact with air from a single thread into a net for incapacitating foes. Kumonga, in Godzilla: Final Wars, is shown to have sharp, sword-like legs which were used to slash trailer cars in Arizona.
In the Showa series, Kumonga was a giant spider who lived on Sogell Island. He first appeared when it trapped and poisoned a Kamacuras. Then he trapped Godzilla's son, Minilla, in webbing and closed in for the kill. However, Godzilla arrived and defended his son. Kumonga attacked and nearly succeeded in killing Godzilla, but Minilla helped his father and using their atomic rays, they burned Kumonga's body, severely injuring him. However, Kumonga was not dead and was placed Kumonga on Monsterland, where he lived with many other monsters. In 1999, aliens known as the Kilaaks, captured and mind-controlled the monsters of the island. The kaiju were released in cities throughout the world. But in the end, the humans broke the mind-control and freed the monsters. The monsters were then sent to attack and destroy King Ghidorah. Kumonga took part in the fight by trapping Ghidorah in his thick webbing. After Ghidorah was killed, Kumonga and the other monsters returned to Monsterland.
Kumonga was featured in the 2004 film, Godzilla: Final Wars, not that different in appearance, as one of the many mind-controlled monsters of the Xiliens. He appears in a desert in Arizona where it destroys a trailer. Then suddenly, the Xiliens teleport the spider and the other monsters around the world. They tell the humans that they took the monsters away to save Earth. However, the humans find that the Xiliens were controlling the monsters and the Xiliens release all the monsters again to finish destroying the cities they were attacking. When Godzilla is freed from the south pole and fights the kaiju, Kumonga is released in New Guinea to battle him. At first, Kumonga was able to trap Godzilla in thick webbing, but Godzilla grabs a webbing that was still attached to Kumonga and swings it around in circles before letting go of the webbing. Kumonga soars over the horizon, leaving his ultimate fate unknown.
