Chronos #1

Transported to null-time city Chronopolous, Walker Gabriel is told by Countess di Ravenna that psycho shape-shifter Hayden Glass has escaped prison and is time-traveling to 1998 to kill Walker's younger self. Walker intercepts Glass and drops him off in the Jurassic Era, leaving him there. Meanwhile Walker's younger self steals a time device from STAR Labs for his boss Vyronis. A time cop is killed by Vyronis, who grabs the device, intending to leave Walker as the fall guy. Walker and Vyronis both fall into a time vortex. Walker wakes up alone, in the old west, found by Nathaniel Kent.
