I think the characters look much cooler with scars, shows you are battle hardened. They wouldnt call them permanent scars if you could get rid of them. Each scar tells a story
I only like one scar, that ghas cut that starts above your eye brow and ends under youe bottom eyelid. It looks just like Anakin Skywalker's Scar in Episode III or Seigfried in Soul caliber III.
