Thief Wario is the first disguise Wario learns in Wario: Master of Disguise, and is the default disguise. It can be worn by drawing a tick on Wario with the touch screens.
- Dash Attack - Unlike the attack in the Wario Land series, instead of being used as an attack that also increases Wario's speed, Wario can only dash a short distance, and will end up back where he started when performing the move.
- Sprint - Thief Wario is the only disguise Wario is able to run in.
- Jump - Thief Wario jumps higher than most other disguises.
