One idea for a 'Miraculous Ladybug' thief OC fanfiction could be that the thief OC is stealing artifacts that are actually magical items related to the Miraculouses. The OC could be doing it for a noble cause, like trying to prevent a greater evil from getting their hands on them. Maybe they have a tragic backstory that led them to this path.

They could leave behind clues for Ladybug and Chat Noir, not realizing that they are actually helping the heroes in their fight against the real villains in Paris.
