Fallen Angels
When Sunspot left the school over a misunderstanding, he ventured to New York. Warlock went after him, concerned for his friend, but Sunspot refused to return to the school. Warlock stayed with Sunspot, where the two got caught up with the thief gang known as the Fallen Angels. During their adventures with the Fallen Angels, Warlock showed Sunspot the true meaning of friendship, and how to control his temper. Sunspot finally agreed to go back to the New Mutants, and Warlock went with him.
Loosing a Friend
Returning to the school, the New Mutants were surprised to find no one there. Magneto told the two mutants to stay at the school, but Warlock and Sunspot left when they found a map leading to the island home of the New Mutants' latest ally, Bird Brain. By the time they reached it, the rest of the Mutants were facing a mad scientist called Anti-Mator, who was working for an anti-mutant group called the right. When Warlock and Sunspot arrived, the battle quickly turned in favor of the New Mutants. However, during the chaos, no one noticed that Cypher was shot in the chest until it was too late. Warlock became confused; on his world, it is normal to consume the body of a dead teammate. Also, he did not understand the concept of heaven; watching shows with zombies only confused him more. When no one was around, Warlock broke into the funeral home and stole Cypher's body. Nothing happened; Warlock thought Cypher needed to be reminded of what it was like to be alive. He used his shape-shifting powers to "animate" Cypher's body and took him to see Wolfsbane. Rahne was horrified at what he had done, but realized it was Warlock's way of getting his friend back. Eventually, she managed to convince Warlock to put Cypher's body in its rightful place.
During the Inferno story line, demons from Limbo began invading Earth. During the various battles in the streets of New York, the New Mutants found out that Magneto was in league with the Hellfire Club and that he had made a deal with the chief demon responsible for Inferno, N'Astirh. After Inferno was over, the New Mutants confronted their headmaster, then ran away to X-Factor's sentient base, Ship.
After a second lengthy adventure in Asgard, Warlock and the New Mutants met their new leader, a mysterious man named Cable. They came to his aid whilst he was fighting Freedom Force, a government-sponsored team. This put the team in hot water with the US government, so Cyclops suggested Cable and the New Mutants take up residence in the basement levels beneath the ruins of Xavier's mansion (which had been destroyed during Inferno). The team spent the next few weeks battling foes such as the Morlocks, who had survived the Mutant Massacre, and the Mutant Liberation Front. Eventually, the X-Men joined the New Mutants in Xavier's mansion, after using a ghost town in Australia as a base.
Death
Soon afterwards, the Genoshan government targeted the X-Men and the New Mutants, since they had allied themselves with Cameron Hodge, an enemy of X-Factor. Since the attack was without warning, Warlock, Boom Boom, Wolfsbane, Rictor and Storm were all successfully captured. The prisoners were "digitally transferred" to Genosha, which severely weakened Warlock. Still, he valiantly attempted to save his fellow prisoners after he learned that the Genoshan council planned to turn them into mindless mutant slaves. He knew that his friends would have no chance if they brought him along in his weakened state; Warlock insisted that they leave him were he was. They did so, but Warlock was easily defeated and recaptured by the Genoshans once more. Warlock was killed by Cameron Hodge, who was trying to steal his powers. When trying to do so, Warlock's body was reduced to ashes. Since the world thought Warlock was a regular mutant from Earth, his ashes were put on top of Doug Ramsey's grave.
Douglock
When the Phalanx came, they absorbed the remains of Warlock and Cypher. This created the being known as Douglock, who had all the memories of Doug Ramsey. He then joined Excalibur at Muir Island for a period of time. At that time, the team was based on Muir Island, which was owned and run by Moira MacTaggert. While his teammates were unnerved by his similarity to Doug, Douglock was eventually accepted as his own person. He acted as a tutor to Meggan and enjoyed a brief romance with fellow teammate Wolfsbane, foster daughter to Moira. This romance would cause him to react irrationally and dangerously at times, mainly destroying valuable scientific research because he did not understand it was more important than his budding relationship with Wolfsbane.
In a bid to seize control of the UK, the covert intelligence operation Black Air allied itself with the London branch of the Hellfire Club in order to raise an ancient demon from its crypt below London and use the ensuing chaos to their advantage. Black Air kidnapped Douglock to use him as the conduit to the crypt. However, after being lost in the time stream, Captain Britain ended up in an alternate timeline, where Black Air was successful in its plans, leading to a dystopic future. Using this knowledge, he and Excalibur were able to defuse the Hellfire Club, enter Black Air's HQ, rescue Douglock and stop the demon's resurrection.
Douglock would continue to mishandle other aspects of earthly life. Despite his believing he could handle it, Douglock became inebriated during Captain Britain's bachelor party and passed out; he later experienced temporary memory problems as a result of the episode.
Return as Warlock
Douglock eventually discovered he was a reanimated Warlock with all the memories of Cypher, and changed his name back to Warlock. After a very brief reflection period, he set out as a solo adventurer apart from the other mutants. In his travels, he met a girl immune to the techno-organic virus. Her name was Hope, and she possessed the power to infect others with any virus that had been implanted in her; she could also create inanimate techno-matter that could be turned into weapons. Later on, a novice member of the Psi-Cops, by the name of Psimon, joined the pair. Throughout their time together, they teamed up with Shadowcat, battled against Spider-Man, caused trouble for Iron Man and fought against Psycho-Man.
