YMMV / Justice League Unlimited S 1 E 12 Weird Western Tales

• Complete Monster: David Clinton was once a weird little man who used time travel to steal artifacts throughout history, but after his sensitive ego takes one too many blows from his dissatisfied wife Enid, David transforms himself into "Lord Chronos". Altering the future to one where he has killed off the Justice League and its hundreds of members, Chronos conquers Gotham City and empowers the Jokerz with technology to run rampant and terrorize innocents. Having trapped Enid's mother in a "cruel thing" where he has kept her for a long, long time to control and abuse Enid, Chronos further showcases how brutal his control of time can be as he transports his snitch minion Chucko to the exact moment the dinosaurs were wiped out to kill him. Though at first merely uncaring that his actions are tearing apart reality, Chronos decides to further gain power by traveling back to the beginning of time, wipe out everything that has ever existed, and recreate time in his own image.
