Zetton[2][3] (ゼットン Zetton) is a beetle-like Kaiju that first appeared in the final episode of the series Ultraman. First appearing in the series as the bioweapon invasion monster of the Zetton aliens, Zetton is considered to be the most powerful monster in the original Ultraman series, and made many future appearances. However, more powerful Kaiju have appeared since then, though numerous stronger forms of Zetton have also been introduced throughout the course of the series as well.
