Coleoptera Worm Argentum

Coleoptera Worm Argentum appeared in 2006 TV series called Kamen Rider Kabuto. Coleoptera Worm Argentum (コレオプテラワーム・アージェンタム Koreputera Wāmu Ājentamu) is a Worm with a pair of large hook claws on the right hand, eight retractable legs in the torso ideal for crawling on walls, and a proboscis used for draining fluids of victims.

It molted with the two other Coleoptera Worms from a group of Salis Worms fighting Shadow, racing away with Croceus after Aeneus was destroyed by Kabuto. It used its retractable legs to run at high speeds, but the Kabuto Extender caught up with them and Kabuto destroyed Croceus as well, Argentum escaping. Argentum later reappeared and fought Shadow again, attacking the new The Bee, but Kabuto arrived and destroyed it with his Rider Kick.

Coleoptera Worm Argentum is the first Worm that Tsukasa encounters in the World of Kabuto while it assumes the form of a young man. After the ZECT Troopers confine it, Gatack and The Bee attempt to fight the Worm who overwhelms them in its Clock Up state. But with the unseen aid of Kabuto, the Worm is destroyed by The Bee's Rider Sting.

Coleoptera Worm Argentum, among many other revived monsters, was part of the Dai-Shocker army in the World of Decade that was fought and wiped out by a gathering of 25 Kamen Riders.
