Ghost Man appears to be a robot which looks like it is hidden underneath a bed sheet, although the sheet could in fact be armour. The sheet is white to represent the ghostly image and his legs and arms are dark grey. He has a blaster. Black eyes are visible through the sheet.
When Pac Man eats a power pellet, Ghost Man turns blue as a sign of weakness.
He is aggressive and holds a bitter rivalry with Pac Man. He likes to use insults to assert his authority.
He has a blaster capable of damage, although he does not use it. He has an ability to glide across the floor at an unbelievable speed.
