The Argus (The Argus Vol. 2 #1)

Time travel is real! Scientific prodigy Randall Patton has had a breakthrough that allows travel through the timestream, which immediately led to the creation of The Argus, the temporal law enforcement organization that polices the time/space continuum. After an accident renders one of the members of The Argus insane, he begins killing off the others - except they are all versions of Randall Patton from various points in his own life! Who can stop Randall but himself?
