The Three Gorma Idiots: Boss Kamikaze, Teacher Telephone and Company President Gravestone
from Gosei Sentai Dairanger, 1993. Designed by Michael Harawata (a.k.a. Kyuto Oida).
These are pretty genius, especially Gravestone, whom can open his grave-head like a zippo and trasform himself into a flamethrower.
