tiny wario
A depowered form of Wario.
In Wario Land: Super Mario Land 3 & Virtual Boy Wario Land, Wario becomes this when damaged by an enemy and can no longer do his usual attacks like the Shoulder Bash. In Wario Land II it's one of his many transformations, inflicted by a Wizard. Despite losing many of his attacks, it allows him to jump higher and squeeze through small crevices. In WarioWare: Smooth Moves, Wario is accidentally separated into a plethora of multiple Tiny Warios by a motorcycle given by Penny Crygor.
As the name suggests Tiny Wario is smaller in stature compared to regular Wario, often lacks his usual grin and doesn't wear a hat, revealing his bald head or a mohawk. In the WarioWare series instead of the shirt and overalls he wears a yellow singlet with yellow gloves and blue shoes.
