The titular Skibidi Toilets, stylized as ΣΚΙΒΙΔΙ, romanized as SKIBIDI. They were the main antagonists of the series until the Astro Arc.
They were the primary adversaries of The Alliance before teaming up with them to top the Astro Toilets (the current main antagonists after the beginning of the Astro Arc) and becoming the tetartagonist of the series.
Skibidi Toilets are a species originating from outer space and are designed as an army of singing, mobilized, sliding toilets with human heads which can turn humans into more Skibidi Toilets by singing the Skibidi Anthem. They often wield weapons and modifications, much like their main adversaries, The Alliance.
