General Deathgiller is a swordsman who serves as the field commander of the Dark Science Empire Deathdark and a major antagonist in Dai Sentai Goggle-V.
Deathgiller oversaw the plans of Deathdark until Grand Marshall Deathmark stepped in an took over, allowing Deathgiller to go out and fight Goggle V more often.
After being defeated once, he was found and nursed back to health by the Goggle V, only to betray them and go back to Deathdark once he had fully recovered.
After Bear Mozoo was defeated, Deathgiller told Deathmark not to revive Bear Mozoo, requesting that he let him pilot the Bear Kong so he could fight the Goggle V personally. He was defeated and ultimately killed by Goggle Robo.
