(X-Men II#42 (fb) - BTS) - As a child, well before he even knew he was a mutant, Francisco Milan dreamed of seeing the wonders of the universe.
(Uncanny X-Men I#300 (fb) - BTS) - After manifesting his electropathy, Milan became a follower of the teachings of the supposedly deceased mutant savior Magneto. He eventually joined the Acolytes at their headquarters in France's Mont St. Francis monastery off the coast of Normandy.
(Uncanny X-Men I#315 (fb)) - Milan, Cargill and Unuscione were sent to Switzerland to investigate rumors of a mutant boy living alone in an empty church atop a mountain ridge. It turned out to be the phase shifting mutant Simon Hall who, after talking with the Acolytes for several days, decided to join their cause as Neophyte.
(Uncanny X-Men I#300 - BTS) - The Acolytes abducted Moira MacTaggert from her lab on Muir Island to make her pay for her blasphemous sins against their lord (when he was a baby under her care, Moira had tampered with Magneto's genetic make up in an attempt to prevent him from becoming the mass murderer they'd known). Fabian Cortez ordered Milan to use his powers to scan and record Moira's entire memory so they had a complete overview of all her crimes. However, Moira proved extremely stubborn and strong-willed, making accessing and processing even the smallest of memories an arduous task.
(Uncanny X-Men I#300) - When his latest foray into MacTaggert's mind left him exhausted with very little to show for it, Milan admitted to feeling a failure. Cortez and his second-in-command Amelia Voght would hear nothing of it and commended him for his supreme efforts. Cortez initially told him to take some rest and start fresh in the morning, but when the weakened but defiant Moira reminded him that she knew he had killed Magneto, Milan was summoned immediately. Cortez ordered him to drain her entire memory at once, hoping it would silence her before she could threaten his position among the Acolytes. Milan remained committed to this "sacred task" even after the X-Men had invaded Mont St. Francis to rescue Moira. Before he could siphon all her memories, Milan was hit in the back by a volley of Archangel's razor-sharp wings. Archangel's attack also destroyed the video monitors and databanks Milan had used to store and display Moira's memories.
(Uncanny X-Men I#300 - BTS) - Amelia Voght used her powers to teleport all the Acolytes to safety after they lost their battle against the X-Men.
(Uncanny X-Men I#304) - On board the Leningrad, Milan and his fellow Acolytes were outraged when the mysterious Exodus arrived in their midst to reveal their leader Fabian Cortez had been responsible for the supposed demise of their lord and savior Magneto. Milan watched as Cargill, Unuscione and the Kleinstocks jumped Cortez and started pounding on him. Exodus then established himself as the new leader of the Acolytes, taking them away from Cortez to Salem Center, New York. They arrived in time to see how Magneto had come to disrupt the funeral of Illyana Rasputin to announce his return. Milan and the others were thrilled to see Magneto had survived and were all lifted back to Avalon, except for Senyaka who Magneto pulped on the spot for perceived transgressions. Some time later, Milan and the Acolytes were joined by their latest member Colossus who following his sister's death had lost faith in Charles Xavier's dream.
(X-Men II#25) - Milan and the other Acolytes were present when Magneto decided to strike back after Earth's governments agreed to initiate the Magneto Protocols (theoretically barring them from returning to Earth). He watched as the master of magnetism went out into space to make short work of the satellite system used to enact the protocols. He unleashed a planetary wide electromagnetic pulse wave that wreaked havoc with electrical systems, injuring and killing thousands of people. Later, when a team of X-Men led by Charles Xavier infiltrated Avalon, Milan and the other Acolytes were taken out of the fight when Xavier used Avalon's own teleportation systems to transport Magneto's followers to a number of pre-launched escape pods in orbit of the space station.
(Cable II#10 (fb) - BTS) - Even though Cable thought he had disabled Avalon's teleport systems by rerouting the bodysliding program it was based on, Milan managed to undo his handiwork. As a result, the Acolytes could freely move to and from Earth again. However, they still weren't able to access other parts of Cable's old orbiting base, which led them to consider recruiting his aid (see comments).
(Cable II#11 (fb) - BTS) - The Acolytes decided to secure Cable's services through an elaborate plan that involved using the deadly Omega Red to get him to cooperate with them.
(Cable II#9) - Milan and his fellow Acolytes tracked down Omega Red to the sewers of London where he'd been living off the life energy of random civilians he'd kidnapped. Milan was able to access his victims' memories to lead them to Red himself. Instead of fighting him, they offered Red a way to control the death spore plague inside his body that was slowly killing him. Intrigued, Omega agreed to work with the Acolytes and went off to collect a number of artifacts needed to help him contain the infection. His first stop was Muir Island where Cable happened to be staying.
(Cable II#9 - BTS) - Cable proved unable to stop Omega Red from taking off with a biocellular subcutaneous matrix stabilizer.
(Cable II#9) - Just before Cable could go after Omega on his own, Milan and the other Acolytes showed up on Muir Island to offer their aid.
(Cable II#10 (fb) - BTS) - The Acolytes, led by Amelia Voght, only told Cable half of their story: they claimed that they'd offered to help Omega Red in hopes of having him join their cause, only for him to betray them. Cable took Voght at her word, but packed extra ammo just in case he was wrong.
(Cable II#10 - BTS) - Cable, Milan and the Acolytes followed Omega Red's trail of death and destruction to Russia's Tyuratam Space Center where he killed the research director of project Epsilon, but not before extracting the data from him he required.
(Cable II#10) - Several hours later,
Cable and the Acolytes arrived at Tyuratam. After taking care of the
soldiers who wanted to arrest them, Milan found the recently deceased
director. Using his portable monitor-feed, Francisco replayed the man's
final memories and confirmed Omega Red had indeed been there. Because
the cure the Acolytes had proposed could only be safely administered in
space (if something went wrong, the death spore virus would become
airborne and wipe out mankind). Therefore, Amelia Voght reasoned Omega
Red wanted to reach Avalon and the only way to get there was by using
the teleportation systems in Magneto's arctic base. Cable agreed to
accompany the Acolytes there. (Cable II#10 - BTS) - The other Acolytes, led by Colossus, were already at the Arctic base where they laid a trap for Omega Red and successfully captured him.
(Cable II#10) - Once they entered the base, Amelia Voght noted it seemed somehow alive, while Milan realized its alien nature rendered his technopathy completely ineffectual. Pretty soon afterwards, Cable ran into the defeated Omega Red and realized he'd been played for a fool. Voght explained the true purpose of their mission, even as Colossus and the other Acolytes came in to surround Cable.
(Cable II#11) - Cable managed to evade the Acolytes,
using his innate control of the exotic, reactive base systems to his
benefit. The Acolytes split up to search for him in the cavernous base.
Milan was paired up with Javitz and Cargill, all the while complaining the
base made it impossible for him to get a good reading on his monitor. This
led the snarky strongmen to comment that this made their teammate even
more useless than usual. Before he could defend himself, Milan was
surprised his monitor suddenly locked on to Cable's mind and showed a
picture of himself hanging upside down. Seconds later, Cable dropped from
the ceiling, grabbed Milan and pulled himself up through the ceiling
again. (Cable II#11 - BTS) - Cable knocked Milan out, thereby eliminating the Acolytes' sole way of tracking him.
(Cable II#11) - Milan remained unconscious throughout the rest of the confrontation between Cable and the Acolytes. Their immediate argument ended when it became clear part of the Acolytes had planned to allow Omega Red to start the risky procedure that would cure him right there in the Arctic. They knew that the death spore virus would be released either way, wiping out mankind in the process. Teaming up with Voght, Colossus and a handful of Acolytes not willing to kill billions, Cable tried to stop Omega Red. In the end, it was the Acolyte Katu, who hated Red because he'd killed his wife and family years earlier, who sacrificed himself by turning his power inaward and seemingly evaporating himself and his opponent. Voght and Colossus took Milan and the other Acolytes back to Avalon.
(Uncanny X-Men I#315) - The Acolytes eventually captured Neophyte and put him on trial aboard Avalon for having aided the X-Men during their assault on Mont Francis. He would have been summarily executed for his crimes, if not for Colossus standing up for Hall and demanding at proper trial. During the proceedings, Milan was called to testify. Using his electropathy, he visualized his own memories of first meeting Hall in Switzerland and taking him in. Milan then added that he now knew Neophyte had been planning to betray the Acolytes from within all along. Colossus defended Simon, pleading for his life and not without success: instead of killing him, Exodus banished the boy from Avalon back to Earth.
(X-Men II#41) - When the intergalactic M'Kraan crystallization wave hit Earth, Milan and the Acolytes were with the comatose Magneto in Avalon's throne room.
(X-Men Prime#1) - When the Acolytes picked up a strange ice comet that appeared out of nowhere near Avalon, Milan joined Colossus, Cargill and Rusty Collins for a spacewalk to check it out. Milan used his powers to send all they observed directly back to Avalon where the zealous Exodus eagerly awaited the results. Milan and the others concluded there was a man inside. Believing this to be an important portent and proof that great times were at hand, Exodus ordered them to return him to Avalon (the man was actually the energy vampire Holocaust from Earth-295).
(X-Men II#42) - Milan was tasked by Exodus to find
out all he could about their mysterious guest. Using his electropathy,
he reported that unlike what they previously believed the man wasn't an
alien, but a human mutant with one of the most powerful mutagenic
signatures ever seen. Exodus ordered him to try and access the
unconscious figure's memories which Milan started to work on by himself
in his laboratory. When he finally made contact, he found himself
overwhelmed by the stranger's warped, garbled memories of Earth-295
which saw Magneto leading the X-Men against Apocalypse. As a result of
their mental connection, Holocaust was able to absorb Milan's lifeforce
to replenish his nearly drained personal energies. Milan seemingly
perished in the process (see
comments).(Heroes for Hire I#16 (fb) - BTS) - Somehow surviving the ordeal, Milan rejoined Exodus and the Acolytes during their extended occupation of the High Evolutionary's Citadel of Science on Transia's Mount Wundagore. They soon found themselves in conflict with the Citadel's former inhabitants, the Knights of Wundagore led by Quicksilver. Exodus' reason for taking the Acolytes there was to secure Isotope E, an evolution controlling compound created by the High Evolutionary. However, the H.E. had taken the Isotope with him when he moved the Knights to Haven, a sanctuary near New York City.
(Heroes for Hire I#16) - After
a convoluted series of events that saw the Heroes for Hire get involved in
the ongoing conflict between the Acolytes and the Knights of Wundagore, it
was revealed at Mount Wundagore that the Man-Beast had been hiding among the
Knights as Sir Anon. The sly Man-Beast had captured the H.E. and his
Isotope E scepter, threatening to kill him if the Knights didn't obey his
orders. Exodus and Man-Beast agreed to a temporary truce when the Heroes
for Hire came to Transia and attacked them. During the combat, Milan
managed to get the drop on Iron Fist, ramming into him to throw the
martial artist for a loop. The outnumbered heroes ultimately proved no
match for their opponents and were defeated and imprisoned.
