Dark Fawful Guy
From the Super Mario Wiki
Dark Fawful Guys are dark purple Shy Guy enemies with blue Fawful masks that are found in Mario & Luigi: Bowser's Inside Story. They carry a Dark Fawful Bomb. To attack them, Bowser can inhale them and Mario and Luigi will fight them; if he doesn't after a certain number of turns, the Dark Fawful Guys will drop the bomb on Bowser, which causes a great amount of damage. The Dark Fawful Guys have the same attacks as their normal counterparts, except they are a lot more powerful and quicker. If Bowser inhales the Dark Fawful Guys, the Dark Fawful Bomb will fall on the other enemies and damage them.
Inside Bowser's body, a Sunnycide-like noise will be heard, and the Dark Fawful Guys will be eaten and turned into eggs. They will then be flung at Mario and Luigi. The bros need to jump over the egg to avoid taking damage. If Mario or Luigi manage to land on the egg, they will break it and cause the Dark Fawful Guy inside the egg to take damage. They will also do a somersault in an attempt to hurt the bros, like Woozy Guys. Occasionally, they will release an umbrella (similar to a Glide Guy) which will delay their fall time. Both these attacks are countered by the hammer.
