Fern Monger

The Fern Monger appeared in 1981 TV series called Taiyo Sentai Sun Vulcan. Fern Monger (シダモンガー Shita Mongā, 11) is a fern-themed Monger of Machine Empire Black Magma. Fern Monger posed as a fern that Black Magma tricked a plant scientist named Doctor Uemura into making poisonous by giving him a Dark Q modeled after the man's late daughter Yumi. Once the modification is completed, the Monger plants his poison ferns around the town until the Sun Vulcan trio intervene and the monger escapes them via his Poison Fern Gas. However, the poison is not deadly and thus underwent around modification to become fully lethal. However, after Misa gets Uemura out of Black Magma's clutches and the Yumi Dark Q was destroyed for refusing to follow orders to kill the scientist, Fern Monger battles the Sun Vulcan trio before being defeated with the Vulcan Ball. Enlarged by his Expansion Program, Fern Monger is destroyed by Sun Vulcan Robo.
