Morlun is a fictional comic book supervillain in Marvel Comics' shared universe, the Marvel Universe, and a foe of Spider-Man. Morlun first appeared in The Amazing Spider-Man vol. 2, #30 (June 2001), created by writer J. Michael Straczynski and penciler John Romita, Jr..
When Spider-Man met a similarly-powered man named Ezekiel, Ezekiel explained to him that Spider-Man's powers were not an accident, and that the spider that had bit him did so voluntarily to pass its abilities onto Peter before it died. This made Spider-Man a "totem," a bridge between man and beast, with the properties of both. Ezekiel then warned Spider-Man that as a totem, he was in danger from those who would seek to destroy such beings. One of those, who showed up soon after, was Morlun.
Little is known about exactly what Morlun is and where he comes from. According to Ezekiel, as long as totemistic forces have walked the earth, there have also been those who have fed on them. While Morlun and his brothers (it is not known how many there are in existence, but Morlun is not the only one) can subsist on the life forces of normal humans and non-totemistic superhumans for a time, they always crave a pure host and Peter fits the bill perfectly.
After Peter's meeting with Ezekiel, Morlun and his hapless minion Dex subtly began tormenting Peter from the shadows, stalking him and wreaking havoc with his spider-sense. Morlun finally revealed himself when Spider-Man was investigating a fire at the wharfs, punching him with what Spider-Man claimed was the hardest punch he had ever felt. Morlun then told Spider-Man that he would eventually kill him, and now that they had made physical contact, he could find Spider-Man wherever he went. Though Spider-Man fought back, Morlun continually regained the upper hand. Peter tried to flee, but Morlun was able to find him easily and resume the fight. Spider-Man finally got away after Morlun burned down the building they were fighting in, but Ezekiel told him it was no use. Morlun would find him once again, and kill him.
