• Laid: Means "ugly" referring clearly to physical appearance, and is more neutral or formal than "vilain."
• Canaille (noun): Means "rascal" or "scoundrel," focusing on bad behavior similar to “vilain” as a naughty person, but often stronger or more derogatory.

• Use "vilain" for describing something unpleasant or ugly (often informal) or for calling a child naughty in a somewhat affectionate or chiding tone.
• Use "méchant" for emphasizing meanness or cruelty, and "laid" for purely physical ugliness.
