Dead Man Walking

Dead Man Walking, known to the Plumbers as Dead Ringer, is an interstellar murderer that has eluded capture on several different worlds.

Appearance
Reports on Dead Man Walking's actual appearance are few and far between, and are wildly inconsistent. His appearance varies based on the planet that he was last seen on, typically matching that of his latest victim. In some cases (notably among those who would be able to notice this) his head appears to be decayed in some form, appearing as just the skull.

Personality
The only thing connecting Dead Man Walking's victims are their injuries, which are usually three holes around the heart with occasional signs of struggle. It is unknown if these injuries are a facet of DMW's powers or personality. The only other connection is that the series of murders only occur on one planet at a time, however the order of the planets he attacks are seemingly random.
