Time Masters #1-8 (1990) Complete

The clock is running out on the past…and if someone doesn't do something about it, there won't be any future. That's where the TIME MASTERS come in. Rip Hunter, inventor of the fabulous Time Sphere and leader of the legendary troupe of time travelers, is back with his crew to track through time a terrible conspiracy that has brought mankind to the brink of disaster. The only hitch is that no one but Rip and his friends believe that the conspiracy even exists. Time Masters travel back through the ages, tracing the threads of this conspiracy and coming into contact with some of DC's greatest heroes of the present and past, including Doc Magnus of the Metal Men, Booster Gold and members of Justice League International.
