History
In this reality, when Rogue touched Ms. Marvel to absorb her powers, Carol grabbed onto her arm and didn't let go. In addition to Carol's Kree DNA glitching Rogue's powers, the prolonged contact caused each to end up absorbing the powers, memories, and personality of the other. Carol sought the help from many people to return to her past self to no avail.
This reality's Rogue and Carol Danvers were briefly visited by Carol's counterpart from the Prime Marvel Universe using the power of the Reality Stone, since the gem linked her to the wielders of the gem in other realities, with the wielder being Anna Marie in the case of this universe. They talked about the differences between their lives before the visiting Carol was pulled into Earth-70875.[1]
