Saw: Rebirth 漫画

Saw: Rebirth, a comic book prequel to the original film released to promote Saw II. Its canonicity was later contradicted by events in Saw IV. It is, however, the first canonical appearance of Jigsaw's wife, Jill, who was later introduced into the film series in Saw III and established still-canonical elements of Jigsaw's backstory (an engineer who is dying from brain cancer).
