Morlun first appeared in “Amazing Spider-Man” comics in 2001.
“Morlun is a vampiric being who has walked the earth for centuries. He feeds on the totems-- the core power sources of the universe. While he can feed on lesser sources such as humans and super humans, he requires a pure source to fully satiate his hunger.”
Till now most of Spidey’s enemies in the films have been more well traveled, classic faces from his extensive rogues gallery, but Morlun is relatively new to Peter Parker’s universe.
