Rahne Sinclair was first shown on a monitor in Ultimate X-Men #43. She briefly appeared as a member of a circus freak show before joining Stryfe's Mutant Liberation Front. She appeared to be fatally wounded by a Sentinel in Ultimate X-Men #87. She later resurfaced as a member of Alpha Flight calling herself Sasquatch. Like all members of Alpha Flight, Rahne used the power-enhancing drug called Banshee to augment her mutant abilities.
An unidentified Sasquatch, who was actually a teenage boy, was mentioned to have been killed, off panel, in Ultimate X-Men #59.
