|First Appearance||Mazinger Z vs. Devilman|
Bugo is an amorphous demon that looks like a purple blob with a single eye and a pair of antenna.
Bugo is a loyal member of the Demon Tribe, proudly following the orders of both Zanon and Sirene. He personally wants to take down Devilman for betraying them and fighting for humans.
Bugo's amorphous form is his main mode of combat, allowing him to strech and cover his opponent in order to suffocate them. He is also able to survive underwater and make materials dissolve.
Bugo was freed along with the other demons in the Himalayas by Dr. Hell. He later paired up with Sirene to attack the Photon Power Laboratory to take out the Jet Scrander so that the Mazinger Z is unable to fly. Bugo manages to damage some of the craft before being driven off by Koji Kabuto's Photon Gun. He later lures Devilman into the ocean where he manages to get his body around the former elite guard. Bugo is later destroyed by the Z during the final battle aboard Dr. Hell's Flying Fortress alongside Sirene and Zannin.
