Skull

This is Skull, a fighter of the savages

He's relatively old, and has lived a lot of years traveling, meeting  lots of cats both hostile and not. He joined the savages hoping for a  place to settle down a little, though he was quickly made a fighter and  expected to work patrols and constantly hone his battleskills. He  obliged but is mostly just really tired and ready for retirement.

His fighting him skills made him one of Tooth's favorites, and when Tooth left to form the teeth, Skull followed without much fuss. His apathy towards the idea and general tired-old-man-ness has made him loose favor with his new leader.
