ZZ I DON'T PLAN ON READING IT

TIME MASTERS 1990 SPOILER to the  ENDING

Rip Hunter travels(the third method) to prehistoric times, in a attempt to kill Vandal Savage before he becomes immortal.  In this storyline, Vandal becomes immortal from being exposed to radiation from a meteor.
Rip shoots Vandal, then proceeds to beat him to death with a rock.  Dripping in blood, he looks up, to see a boy in the bushes who was watching.  This boy turns out to be Vandal Savage(Jr).  In this tribe, the sons take the fathers names after their death.
So...in this version Rip Hunter, in a sense, creates Vandal Savage by killing his father in front of him.(trippy but I liked it.) Also ....Rip Hunter finally sees the folly of trying to change time at the major points of history.
Rip can't bring himself to kill the boy before the meteor hits.
Not only that.... but Rip is stuck in time in the prehistoric age, so not really ending the story, at least not for me.

DON'T forget that this is RETCONNED
