Grand Marshall Deathmark

General Deathgiller is general of the Dark Science Empire Deathdark. A swordsman field commander in black.

He was the first of Fuhrer Taboo's second in commands and oversees the plans of Deathdark until Grand Marshall Deathmark arrived and enables him to go into the field more often. As a swordsman, he often clashes with Goggle Red and considers him a worthy opponent in combat.

He eventually went along with Deathmark's plan in turning Mazurka into a walking bomb while she infiltrates the Future Science Laboratory, and during the ensuing explosion, Deathgiller vanished, and was later found by the Goggle V and was instead nursed back to health. Even though he showed no gratitude of being nursed back, he occasionally interrupts the recent Bear Mozoo from obliterating the Goggle V, claiming that it will be him to defeat them personally.

On the death of Bear Mozoo, Deathgiller returned to Deathtopia and demanded that Deathmark did not revive Bear Mozoo and instead let him pilot the Bear Kong for his final battle against the Goggle V. He lost his life in process.
