The Phantom's Rings
A signature of the Ghost Who Walks is his two rings. "The Evil Mark" or "Skull Mark" has a skull shape, which leaves a scar of the corresponding shape on the enemies he punches with it.
The Skull Mark ring was given to the first Phantom by Paracelsus. The original owner of the Skull ring was Emperor Nero of the Roman empire and it would later be revealed that the ring had been made from the nails that hung Jesus to the cross.
The Good Mark ring has a pattern formed like four crossing sabres, that the Phantom leaves on visitors whom he befriends, placing the person under his protection. The Good Mark ring was made after the sixth Phantom founded the Jungle Patrol.
The Phantom wears the Evil Mark on his right hand, and the Good Mark on his left, because it is closer to the heart.
