Gelnewt (Ryuki)

Gelnewt appeared in 2002 TV series called Kamen Rider Ryuki. Gelnewt (ゲルニュート Gerunyūto, 17 & 18): A humanoid Newt monster that wielded a shuriken as its weapon and could produce globs of sticky gel. It avoided a double Strike Vent blast from Ryuki and Raia (using Copy Vent), before later being destroyed by Ryuki's Dragon Rider Kick Final Vent. Gelnewt appeared in Shinji's dream during the Hyper Video special, being among those destroyed in Zolda's End of World Final Vent.

Gelnewts serve as the Oni Brothers' foot soldiers. They accompanied Mimihiko in acquiring a vase for their master's agenda. Unlike previously, they talk and wield swords.

A brief glimpse of their "true" oni faces is seen, potentially suggesting these foot soldiers aren't actually the same monster as Ryuki 's Gelnewts. Looking for the Trump Stone, they try twice to chase the boy Yu, but fail first to New Den-O, then to Yu escaping to the DenLiner. Serving Kuchihiko in the 1500s, they attack a village but are fought back by the arriving DenLiner crew. They again fight the crew and villagers when attacked, but are eventually defeated along with the Oni Brothers.
