Saitama And The Mediocre Ability Users
Dirt Earthworm appears after Saitama meets the Mediocre Ability Users and they accept their weakness. His movement rumbles the ground and causes an evacuation order to be announced. He tells Saitama and the Mediocre Ability Users that he is sick of the humans covering the Earth with concrete and wants to assert his dominance. He creates a massive wall of earth to crush them, but Saitama stops it. He pursues Dirt Earthworm and punches into the ground after him, but Dirt Earthworm's small body lets him avoid it and escape.

Dirt Earthworm is later seen sticking out of the ground to watch Saitama train the Mediocre Ability Users. He gloats that nature is on his side and that he plans to strike again. However, in his distraction, he is cornered by a random sparrow that quickly devours him and flies away.
