Waraikozou of the Gremlin is a flea-themed member of the Earth Condemnation Group Yuumajuu and is the main antagonist in episode 21 of 2010 TV series called Tensou Sentai Goseiger.
He is voiced by Chihiro Suzuki who previously voiced Grand Beast Rei, a Drill Banki, Hyakuyappa and later voiced a Persimmon World and the Great Persimmon World. Also from the Kamen Rider franchise he'd voiced a Spider Imagin and a Clown Imagin.
Waraikozou is sent by the Yuumajuu to cause chaos in its own bratty way, disabling and corrupting electronic systems throughout the city. During one of its getaways, it ends up hurting the hand of a baker, whom Eri decides to help for the day even as Waraikozou continues to rampage about and Gosei Knight criticizes her behavior in helping another human.
However after making a cake that she had to help with, Eri uses her training in baking to knock around the Yuumajuu with flour and a bowl before the team finishes it off with the Skyick Strike.
After being grown, it is quickly defeated by the combined effort of Gosei Great and Gosei Ground.
The childish Waraikozou loves to destroy anything mechanical, much like what his namesake is infamous for.
- His name is derived from The Twilight Zone franchise.
