Here it is, our first look at the Punisher skull. This is actually an x-ray that Karen is looking at, but it may be safe to assume that it will be very important when it comes to Frank Castle. It's quite similar to the version of the skull of the 2004 film The Punisher, starring Thomas Jane as the titular character, and also the MAX comic series. The skull is obviously extremely important to the character, with it being his insignia and an instantly recognisable sign to people with only a passing interest in the character, so this first look at it is bound to be significant, and if it is indeed directly related to Frank Castle, then may play a part in the origins of the design in this series.
