Rogue and Magneto's relationship began with a "spark" after he assisted Rogue in her fight with the malignant psychic ghost of Carol Danvers, full of resentment towards Rogue for ruining her life, now made corporeal due to the Seige Perilous. Rogue returned the favor by helping Magneto fight against Zaladane who wished to control the Savage Land with brutal force.
Rogue found herself power neutralized and without her teammates in the Savage Land, but in the company of Magneto who retreated to the area after his tenure as the headmaster of the Xavier Institute ended in failure and his bond with his New Mutant students irreparably severed. The two grew close while on their quest to stop Zaladane, a closeness that threw them both for surprise but not entirely unwelcomed given their later interactions.Alas, the savage land romance did not last as Magneto made the decision to return to his former idealogy and methods of mutant supremacy during the Zaladane fight. Rogue tried her best to steer Magneto back to the side of "good" but the damage was done. Magneto and Rogue parted the Savage Land separately and as enemies once again.
However, their mutual feelings remained and eventually became common knowledge to the X-Men.
Rogue attempted to reach Magneto numerous times offering an olive branch and pleading for his return to the X-Men. While Magneto, his mind made up about his path, attempted to recruit Rogue to his side to no avail.
The relationship was famously part of Marvel's Age of Apocalypse publisher wide event featuring an alternative timeline. AoA, saw Rogue and Magneto as a happily married couple with an infant son, fighting together to rid the world of Apocalypse influence.
A return to the original timeline saw Rogue still interested in Magneto, this time believed to be turned into an amnesiac younger man named, Joseph. Rogue and Joseph enjoyed a sweet flirtation yet still unfulfilled romance. Joseph was later revealed to be a clone of the master of magnetism instead of the man himself.
The real Magneto eventually returned, fighting against the U.N. to provide him the sovereign nation of Genosha as a safehaven for mutants and the remaining humans who lived there. Joseph sacrificed his life to repair the damaged EM field around the earth, leaving Rogue heartbroken over the loss of her friend and almost lover.
However, this loss did not deter Rogue as she still hung onto hope that Magneto could be reasoned with and returned to the X-Men's side. While most of the X-Men were on an away mission to space, Rogue flew to Genosha to reconnect with Magneto. She found an ally with Pietro who also wanted to talk sense into his father. Unfortunately for both, Magneto was steadfast and did budge in his decision. As a final act, Magneto allowed himself to be kissed by Rogue to show her the pain within him, the demons he face, to dissuade her from her attempts to rekindle their romantic flame as his focus needed to be on rebuilding Genosha. Once again, Rogue and Magneto parted as enemies.
It wasn't until the creation of yet another sovereign mutant nation, this time by Cyclops, that Magneto rejoined the frey. At this point in history, the mutants were dwindled down to less than 500 due to a genocidal attack against them stemming from a failed and crumbling alternative reality. Cyclops sent an open call to all mutants who wanted to joined the small of Utopia, repurposed from Astroid M, Magneto's former base, floating near the border of San Francisco. Magneto joined the X-Men, saved beloved X-Man, Kitty Pryde, and was trusted enough to join missions. One such mission involved a reunion with Rogue. This time, Magneto was the one actively showing his interest in rekindling their former flame, while Rogue was hestitant to start something up with the man she onced tried so hard to reach.
Rogue eventually took on the role of mentor to many of Utopia's younger mutants to help them control their powers, as her own powers, recently under control for the first time since she was 13 years old, offered an unique perspective that would help the young mutants better understand themselves -- or so Cyclops pitched to her. Rogue continued in her role, often times reuniting with Magneto on missions. The constant run-ins with Magneto eventually led Rogue to soften her stance on the man she once chased across an ocean, but now rebuffs.
Another alternative reality emerged sweeping up everyone within Utopia into a new history, new identies, and a new mystery. The Age of X. Magneto would be known as The General, the leader of the last mutant stronghold. Defending mutants from the constant war with humans. Rogue was known as Legacy(colloquially as Reaper by the Utopians), the living last will & testament to mutantkind. Absorbing and maintaining the memories and life of fallen mutants so they may never be forgotten.
The General and Legacy were rumored to be lovers by the Utopians due to their closeness. It did appear that such rumors were true given the two's brief but personal and intimate interactions with each other. AoX was eventually revealed to be the powers of David Haller, Legion, running rampant due to another personality taking hold of him - the mysterious X. AoX, was no more and Utopia woke up from its fever dream. Most mutants opted to have their memories wiped to avoid the confusion of two lifetimes running in their minds. Rogue decided to keep Legacy alive within herself. As such she gained Legacy's mastery over their shared power as Legacy always had control; thus allowing her powers to grow and mature in a way that Rogue's could never.
The end of AoX saw the beginning of Rogue and Magnetos relationship in earnest. Inspired by Legacy's open feelings for The General and her unwillinginess to live her life in fear, Rogue opted to give Magneto a chance. Magneto, for his part, believed Rogue was still hesitant to be with him due to his past, so he attempted to, once again, dissuade her from a romance by offering up a brutal tale from his past, showing what kind of man he was and is. Magneto was later surprised when Rogue showed up in his room - not promising anything beyond a night together.
The relationship continued from there on, the two remained together even during the schism of Utopia which saw mutants split between Cyclops Utopia and Wolverine's desire to reopen the Salem school to give young mutants a different path in life. Rogue went with Wolverine, but stayed in a long distance romance with Magneto for awhile.
The relationship ended after Utopia was seiged by the Avengers and the Phoenix force split into 5 pieces controling different members of the X-Men (Cyclops, Emma Frost, Namor, Colossus, and Magik).
The Phoenix 5 were then conspired against by the Avengers and a handful of mutant defectors who decided the P5 should be in control of such power. Eventually this led to the P5 being driven insane, and the Phoenix controlled Cyclops murdering his father figure and mentor, Charles Xavier.
Once again, mutants were displaced from their homes with nowhere to go. Magneto wanted to start a new life with Rogue away from everything that transpired, but Rogue was not ready that committment. The two amicably ended their relationship after having an honest conversation about what they needed and wanted at that point in their lives.
A long history spanning the 90s (1991-1999) and part of the 10s. Rogueneto shared an eventful romance that shows the depth of compassion, respect, and understanding these two have of each other. A romance of two strong-minded and fragile-hearted individuals caught in an unsynchronized love affair that all started with a "spark."
