Yosh Calfor was a human male soldier that served as a private in the Alliance to Restore the Republic during the Galactic Civil War as a demolitions specialist. Able to easily handle the most dangerous explosives in combat operations, he prided himself on having at least three grenades within reach. However, he sustained hearing loss from working with thermal detonators, and had to get an electrocochlear implant. Calfor originally owned a bloodhound kennel on his homeworld of Mykapo.
