Mr. Bobs are enemies that appear in Bomberman Hero. They are strange, robot enemies that are pretty common in the game as they are seen in at least one level of a world.
Mr. Bobs are always watching White Bomberman but, oddly, they don't agressive toward him. Mr. Bobs tend to fly around near higher areas or near pathways that White Bomberman needs to go through. Mr. Bobs tend to act on their own and since they don't go after White Bomberman, it can be assumed that they aren't working for Bagular.
