Dark Mechawful.5

A Dark Mechawful.5 is an enemy found in Mario & Luigi: Bowser's Inside Story. When Bowser, Mario, or Luigi destroy a Dark Mechawful and leave the ejecting head alone for a while, the head becomes a Dark Mechawful.5, gaining a new metal body. The differences between the two are:
 * Dark Mechawful.5 stops its timer on its chest, while the Dark Mechawful doesn't.
 * Dark Mechawful.5 has more iron plating, increasing defense.
