Dark Hammer Bro
From the Super Mario Wiki, the Mario encyclopedia
Dark Hammer Bros. are a shady Hammer Bros. variation only seen in the Wii game Super Paper Mario. They are the most powerful form of the Hammer Bro in said game, and can only be found residing in the Flopside Pit of 100 Trials (rooms 46, 66, 93 and 99). They attack by throwing down Hammers at Mario. They have a mighty amount of HP, decent Defense and low Attack Power. While they might not seem a great threat, their hammers can go through the blocks in the Pit, which is very dangerous.
