Pest Regretevator (Guest 1314) is a humanoid beetle thief from Regretevator. He has a blocky appearance, red eyes, beetle horns and mandibles, and a sharp, unsettling grin. He wears a tilted cap with a “P” and a shirt covered in Japanese text such as “Regret” and “Do you regret your decision?”.

Pest survives by stealing coins, parts, and useful objects, hoarding them to build machines and inventions in his hidden den. He is quiet, evasive, and constantly alert, rarely staying in one place for long. He speaks English but often inserts short Japanese phrases, usually when irritated or when hiding his real thoughts.
