Hakon

Hakon was the leader of a band of Vikings who were active in 994 in the animated series "Gargoyles" - he was also a major antagonist of the pre-modern portion of the gargoyles' story and would be responsible for the sacking of Castle Wyvern and massacring the defenceless clan of gargoyles after they had been cursed into an eternal stone-sleep by the Magus.

Hakon would return centuries later as a ghost fuelled by hatred and trapped in an eternal battle with the Captain Of The Guard, however when the gargoyles arrived Hakon alled with his old enemy to once again assault the one thing they hated more than one another: Goliath.
