This article is about a/an Worm in Kamen Rider Kabuto.

The Lanpyris Worm (ランピリスワーム Ranpirisu Wāmu) is a Worm capable of emitting plasma from its ball-like right hand that mimicked an officer it had just killed. The Lanpyris Worm goes after a girl named Yuki Tamai who witnessed its mimicry, assuming her form as the police arrive and arrest it with the girl running off.

Ending up in the Shibakouen Station, the fake Yuki is intervened by Maki, convinced that the girl is human. However, Tendou breaks her out and she runs off to accomplish her objective as the real Yuki meets with her date at the amusement park. Assuming its true form, the Lanpyris Worm battles Kabuto over the entire amusement park at super speed before being destroyed by Kabuto's Rider Kick.

Her human mimic of Yuki Tamai is portrayed by Mika Kikuchi, who is famous for her role as Koume "Umeko" Kodou in Tokusou Sentai Dekaranger.
