|Lethal Doggler the 2nd|
Underground Emperor Zeba (地帝王ゼーバChiteiō Zēba) is the leader of the Underground Empire Tube. He hates all human beings and is a master of the Dark Aura, desiring to turn the surface into a cold and dark place.
His true form was the monster Bizzarre Doggler II (リサールドグラーII世Bizzaredogurā Nisei?) whose father, the original Lethal Doggler, was killed by the Igam Family for terrorizing the underground. Before dying, it spawned an egg that resulted in Zeba's birth; the child devoured his parent to become stronger. The new Lethal Doggler grew with nothing on his mind but revenge, disguising himself as Zeba and overthrowing the Igam Royal Family.
Upon assuming the throne, Zeba corrupted the underground into a violent kingdom and enslaved the underground humans. When he learned that his defeat was foretold to be at the hands of the surviving twin daughters of the Igam family, he kept them apart, taking measures to ensure no one learned about his true identity.
With Ial revived and his identity revealed, Zeba quickly enacted his final plan to raise the Underground Castle and spread his Dark Aura around the world, to usher in an age of darkness at the cost of his followers. Once on the surface, Zeba battled the Maskmen personally in his Dark Aura domain. However, Ial and Igam augmented their powers with the Maskmen's to negate his Dark Aura. Forced back into his true form, the Lethal Doggler was blasted by the Jet Cannon at full power, using the energies from the weapon to enlarge himself before being finally destroyed by Galaxy Robo.
