Gargouille was a member of a faction of Acolytes led by Exodus who participated in an assault on Wundagore Mountain in the European country of Transia, home of the enigmatic scientist known as the High Evolutionary. The Evolutionary had developed a powerful mutagenic compound known as Isotope-E, which the Acolytes coveted for themselves.
Gargouille retained her mutant powers after M-Day.

They were defeated and Projector then answered Logan's question about Exodus' current location.
