On a world taken over by Sentinels, the Exiles met up with another reality-hopping team called Weapon X in Florida. The warm climate prompts Heather to revert to human form which surprises both sides. On most worlds, Sasquatch is the alter ego of Walter Langkowksi and not by the wife of James Hudson, who is a caucasian in most realities. The two teams are shocked that Sasquatch is a black woman.

Heather is a rational skeptic who is very protective of her teammates, as was first evident by her reluctance to work alongside the unnerving, amoral Weapon X who would later clash with the Exiles. When the team visited a reality where creatures called Vi-Locks had infected the world with an evolved version of the Legacy Virus, Heather would again try to save the team from any unnecessary harm. The Avengers concluded that the only pragmatic solution to preventing the Warlock Virus from spreading any further was to crash a plane of nuclear explosives into the Vi-Locks' own store of nuclear reserves and Nocturne volunteered to go on the kamikazee run . Heather vehemently objected to the notion, but was eventually shot down by the majority. It is perhaps this same constant protective behavior that has led Heather to surmise that the Timebroker is not all he appears to be.

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. Sasquatch and Morph would be derailed without the Tallus, separated from their teammates, and stuck in an alternate reality Canada where they find themselves face-to-face with a Wolverine who is at his absolute worse, recently escaped from the Weapon X Program, and, at the moment, more animal than man. After discerning that Morph has no scent for Wolverine to track him by, Heather knocks Morph out cold and hides him underneath a pile of leaves, leaving her free to take on the rabid Wolverine without having to worry about Morph's safety. Heather faces the possibility of having to kill her first love a second time. After some time, Wolverine is able to catch up with Heather. But, as Wolverine moves in to finish his prey, he senses something that causes him to hesitate and halts him dead in his tracks. Heather reverts to her human form and approaches Logan, who goes with his instincts and welcomes her in an embrace. Heather subtly puts her hands around Logan's neck and slowly changes back into her Sasquatch form, but before she is able to do anything, she feels a tingling behind her eyes, the same as it always is before the Exiles teleport away, and she is thankful because, if Logan decided to attack a second later, she doesn't know what she would have done.

The next time the Exiles ran into Weapon X, they were told by the Tallus that, of the two teams that are here, the twelve people from Exiles and Weapon X, only six would move on and the rest must die. The Exiles newest member Magik, became obssessed with abiding by the instructions of the Tallus in order to move on and repair her timeline. As a result, Magik drew her Soulsword and attempted to kill Nocturne. However, Heather caught Magik in the act and pushed Nocturne out of the way, suffering a fatal wound while still in human form in the process. With Heather on the brink of death and left with no other practical alternatives, Nocturne possesses Heather and attempts to trigger her Sasquatch transformation so her healing powers can repair the damage done. Fortunately, this works and Heather survives this near death experience.
