Brush Man

 Brushman is a virus from the Mega Man Battle Network series. They warp around the field, changing a panel's type with their brushes. On the virus side, the panel types can be changed to holy. On the player's side, the panel types can be changed to lava, ice, magnet or poison panels. Variants, as they level up, will be able to change to more dangerous panel types. They have no direct attacks, they warp constantly around the field, and they never appear alone.
