I figured it was time for some more robo-panthers because Wils and Mac never seem to have had much love in my gallery.

R-MAC on the left is a robotic panther who was built by Jakob to make sure he understood the advanced robotics technology he had stolen from another dimensional plane. He is the chief of security and directs the other panthers, who were originally designed to guard military bases.

On the other hand, W-ILS on the right, was a regular Being - Renward Wils - whose soul was installed into a spare panther body after he was murdered. This was intended to be a temporary measure until they could build a suitable android, but Wils was the Furrae equivalent of a Furry and wanted to remain a guard panther.
