What are the best (and worst) Time Travel stories in DC?
As much as I'd love to give it to some of the Silver Age Degaton stories, the best Degaton story (the death of Earth 2 Degaton) didn't have much Time Travel at all. Hourman was good too but...
Chronos, the series, with Walker Gabriel has to be my favorite. It was clever and funny and kind of sad, this one man war against time. It's cancellation was one of the great tragedies of DC.
There have been some doozies, but for me the king of them all has to be the "Future Carol" story in Impulse. This one just hurt my head. Aside from the terrible idea of taking an old wild west foe of Max's and turning him into a time traveler, the main story was built around an incredbily illogical problem.
After years of teasing the readers, Impulse and his best friend, Carol, were starting to move toward being more than just friends. So immediately (and I mean immediately) a future version of Carol shows up and says "no, one day Carol will one day be a brilliant scientist and her research into the Speed Force will be used by a villain, and could destroy the world. The only way to prevent this is to take young Carol and move her far far far into the future, separating you two lovebirds forever." And this is done, and Impulse is very sad, and the book starts on a downword spiral that finally destroys it.
I think any reader with half a braincell probably said "couldn't you just have asked young Carol not to research the Speed Force?"
