The creatures of the Zagon Galaxy (ザゴン星系, Zagon Seikei) are the antagonists of the series.[12] They are led by Alien Zagon and usually fights against the GOKAZOKU members and Ultraman Nice. Their aliases are written in Hiragana in the 2001 magazine.[13]

• Deadly Poison Alien Alien Zagon (猛毒宇宙人 ザゴン星人, Mōdoku Uchūjin Zagon Seijin): A heinous alien from third planet Zagon Star bent on conquering Earth and frequently fights Ultraman Nice. As his alias suggest, Zagon has the ability to secrete poison gas from his ears but was never shown in the series proper.
• Gluttonous Monster Momo-Zagon (食いしん坊怪獣 モモザゴン, Kuishinbō Kaijū Momo Zagon): A pinkish traffic sign/traffic light themed monster from the eighth Planet Momo-Za Star (モモザ星, Momoza Sei) with the ability to unleash sound waves.[10]

• Angry Monster Tabu-Zagon (怒りん坊怪獣 タブザゴン, Okorinbō Kaijū Tabu Zagon): A porcine monster from the fifth planet Tabu-Za Star (タブザ星, Tabuza Sei). It has giant ears capable of assuming as Tabu-Zagon's alternate face with reflective properties but its weak point is its snout.[10] Tabu-Zagon is a late addition to the other monsters, as it appeared during the winter 2000 arc of the infomercial, hence he was absent from a tag team between the Zagon Galaxy creatures.[10]
