Butch is a female second generation ork street doc who runs a clinic in the Redmond Barrens. Butch is also a well known shadowrunner and a member of JackPoint. Butch's real name is Carol Howard. She has a cracked tusk.
She is one of the foremost experts in CFD by conducting a number of ethically questionable experiments in pursuit of a cure for the condition.
In 2076 she aided a team of runners lead by Windhowler to stop an AI who had overwritten a shaman Shadowrunner named Wolf.
Wolf is probably not Wolfgang Kies from Michael Stackpole's Wolf And Raven.
