One day, Mimic found himself in the middle of a barren desert alongside five other X-Men from five different realities. They were greeted by the Timebroker, a construct of their collective consciousness, who explained to them that they had all become unhinged from time as a chain of events had caused their realities as they knew it to change. New events in Calvin's past caused a bus full of innocent bystanders and Senator Robert Kelly to all be killed during the Brotherhood's failed attempt to kidnap Kelly. The only member of the Brotherhood not able to escape, Mimic sits on death row for these transgressions. In order to return to their correct timelines, they would have to repair other realities that caused the ripple effect that disrupted their reality. Should they fail, they would return to these new, unfortunate alternate existences.

After being forced to kill an alternate version of Charles Xavier, a man who had been the closest thing to a father figure to Calvin in his own reality, Mimic concluded that Blink was the only member of the team fit to lead. The Exiles would constantly be facing opponents who the rest of the team would consider family and friends, but Clarice's experience in the very different Age of Apocalypse put her outside the relatively similiar and familiar lives they all led. Mimic added that it was Blink who the Timebroker gave the Tallus. the gauntlet that guides the Exiles through their missions. Doubting her actual ability to lead, Blink reluctantly assumed the role of leadership with Mimic's constant support.

On one of the team's venture where the Exiles were pitted against the Dark Phoenix, Calvin attempted to Mimic the Phoenix Force. Because he can only hold five mutant powers at once, he was forced to forfeit one of his abilities and chose to give up his Angel wings. Unfortunately, the battle against the Phoenix did not last long enough for Calvin to permanently retain the power of the Phoenix Force. Calvin would later regain his ability of flight by copying the powers of the Canadian super hero Northstar.

During their time together restoring the multiverse, Mimic educated Blink in the history and general knowledge of the majority of the other timelines. Because the events that comprised Age of Apocalypse diverged greatly from what could be considered typical in other realities, she had no idea who many of the regular heroes and villains they encountered were. The two grew close and eventually became more than friends.

Over time, Calvin became jaded with the Exiles' way of life. Mimic was growing tired of facing corrupted versions of his friends, family, and fellow heroes in each of the worlds they were forced to visit. This was most evident following a bout with Namor, the Sub-Mariner, a fight that saw Calvin unsuccessfully attempting to rationalize with the raging Atlantean whom he knew to be a good man in his reality. Calvin grew increasingly distant from the rest of the team and his relationship with Blink also waned. When Clarice question him about the funk he was in, Mimic skirted the issue and denied her claims had any validity. After constant harassment from Clarice, Mimic finally caved in and admitted he had grown sick of their lives and wanted to go home. Calvin asked Clarice to tolerate him and to just be his friend for the time being. Although Mimic began to doubt that the Timebroker had anything to do with their collective subconcious, he never voiced his opinion on the matter and instead kept doing what was necessary to support his teammates.

On their visit to a planet that was plagued by an evolved Legacy Virus and ruled by a nation of infected creatures called Vi-Locks, Blink contracted the disease in its purest form while attempt to retrive the body of Cypher in order to create a vaccine. It traveled at an accelerated rate through her body and, though her condition would eventually stabilize, a cure for the virus had not yet been found. While she lay comatose, Calvin visited Clarice in her sick bed to tell her that he was an emotionally detached idiot who didn't realize how much she meant to him until just then.

After Cypher's body was destroyed, both the Exiles and Avengers saw no other pragmatic solutions to the Vi-Lock threat that would now spread across the galaxy other than the destruction of Earth. Nocturne volunteered to pilot an aircraft filled with nuclear warheads on a suicided run to crash land into the Vi-Locks' own store of nuclear weaponry. The explosion from the impact alone would most likely split the planet in half. At the last minute, Mimic hijacked the plane by nerve pinching Nocturne and flew the ship in her place. However, through the combined efforts of Morph and Rachel Summers, the Avengers were able to contact the Norse Gods and use the healing properties within their blood to create a successful vaccine. Blink was treated and was quickly recovering from the illness when she was informed that Mimic had been sent on a mission to destroy the Earth. The Avengers had been trying to contact him to tell him the good news, but all attempts to hail Calvin had been unsuccessful.

Clarice immediately set off to prevent Calvin from destroying the Earth since a cure had been found. She was able to locate him just in time to avert a nuklear catastrohpe that would have split the planet in half. Back at the Avengers Compoud, festivities ensued, though the celebration was halted by the appearance of the Timebroker who had come to inform the Exiles that one of them had repaired their personal broken chain in time and would be sent home. Clarice vanished As their new team member Magik stepped forward, the Tallus was removed from Blink and reappeared on Mimic's wrist. In the blink of an eye, Clarice was gone...

With Blink gone, Mimic not only found himself with a void in his life, but also found himself one again thrusted into the role of leader with the Exiles, a role that he had previously pondered taking possession of, but questioned his ability to do so. Back then, Mimic decided that he was ultimately uncapable of fulfilling this duty. Now, he seemed to have very little choice in the matter and, while he would not embrace the role, would continue doing what was necessary to support his teammates.

When the Exiles defeated a Union Jack who they inadvertantly helped become the Vampire King of his timeline, Union Jack cast an incantation as the Exiles began teleporting to their next dimension that caused the Exiles to be split apart into multiple smaller factions on different worlds in different times. Mimic found himself redirected to a world that had been completely overtaken by the Brood. For four years, Mimic constantly fought off the Brood and never found any other human inhabitants. During this time, he was inplanted with Brood eggs on three different occasions. He was able to fight off and kill the first implantation of the first two embryos over time using his Healing Factor. When whatever caused Calvin to appear on the Brood World put him back on course and reunited him with the Exiles, Calvin hid the fact that he was still infected with a Brood Queen embryo and lied to them by telling them he had only been on the Brood Planet for around six months.

The Exiles then came to a world where the Thing transformed into a psychotic monster. Mimic suffered severe injuries while battling Grimm and was hit hard while not in Steel Form and this put his Healing Factor under enough strain, working to repair his current injuries, for the Brood egg to slowly take him over. The Brood infestation altered his body, creating a unique physiology that enabled him to duplicate any superhuman powers, not just mutant powers, and allowed him to house more than five powers at once. The Exiles were now forced to fight their most powerful member. With every blow delivered, the Brood Queen became more powerful and less of Calvin Rankin occupied his body as his Healing Factor worked harder.

It would be the genius of Reed Richards, Tony Stark, and Otto Octavius that would save the day. With their combined intellectual might, the scientists were able to formulate a sedative that emitted a radiation burst laced with synthetic narcotics that brought the Mimic-Alien hybrid to a comatose state, enabling his Healing Factor to attack the embryo. When Mimic regained complete control of his facilities, he was able to identify that the Brood egg had died. Just when things appeared to have settled down, Morph found Sunfire beneath some rubble. She died trying to save a crowd of people from a building that had been destroyed by Mimic while he was being controlled by the Brood embryo. Because she had expended so much energy fighting Mimic, she was not able to disintegrate all of the crumbling building and was buried alive beneath the debris. Guilt-stricken by the responsibility for the death of his teammate, Calvin swore that he would never kill another ever person again.

616)		Mainstream Universe In our reality, Calvin Rankin was the son of biochemist Dr. Ronald Rankin, who was engaged in research of an unknown nature at the time that Calvin gained his power to mimic the abilities of others. Rankin would find the X-Men's base and introduced himself to the X-Men, supposedly on friendly terms. As soon as Rankin was certain that he had successfully mimicked their powers, he donned a costume he had brought and fought the X-men calling himself the Mimic. Eventually Rankin discovered that his mimicking powers were becoming stronger and less controllable. He might be draining energy from people all over the world without being able to stop himself from doing so. When the monster known as the Hulk happened to be in close proximity to the Mimic, Rankin decided that the Hulk gave him the means of making certain of eliminating the menace that the Mimic posed to the world. Rankin held onto the Hulk long enough to drain enough of the Hulk's gamma radiation into his body in an attempt to kill himself. However, Rankin did not die, but was able to mimic the Healing Factor power of the mutant Wolverine, enabling his resurrection. He later was found by the psychic menace known as Onslaught, who brainwashed Rankin to fight the hero team X-Force. He has since appeared in various incarnations of the Brotherhood.
