This is a piece I did for the Character Design Challenge on Facebook.  This month's theme was to create a Viking.  Sounded simple enough.  I wanted to think a little differently, so I decided to go anthropomorphic on this one.  The first thing that came to my mind was an octopus.  I did other sketches, but the octopus stuck with me.  One of my favorite villains of all time is General Grievous.  In the 2D animated Clone Wars, I loved how he made use of all his limbs.  I see a little of that in this character.  I imagine him being able to block and strike at the same time.
His name is Viktopus.  He swore an oath to protect his home from the invaders... the human vikings!
