The Pest (originally Teigneux) is the typical bad guy, and often a stupid nasty idiot. He’s usually on the wrong side of the argument and rarely agrees with anyone. Only Jumbo fists can keep him in check.
In Once upon a time...Life,The Bacteria were like their faces as the pest and they are now killed by Jumbo as a white blood cell and Metro and the Antibodies.
He can also appear in the world but he instead Harm people or doing negative things to the pest and the dwarf.
