>>91892809>Why does Zoom hate Flash so muchLet's see...
>Pre-CrisisHe didn't really hate him so much as thought that it was dumb for Barry to use his powers for good, instead of doing evil. He admired Flash's powerset, but considered heroics a foolish waste of time. After being foiled by Barry for a few times during Silver Age, he changed his MO into copying Barry's face on himself and trying to steal his wife, Iris. When she rejected him in a Bronze Age story, Zoom killed her (though her consciousness was transferred into the future by her secret parents yadayada whatever). Barry then tried dating another girl, and Eobard tried to kill her just to be a dick, for which Barry killed him.
>Post-CrisisEobard Thawne was a fanboy of the Flash who collected all possible Flash memorabilia and wanted to simultaneously look like Barry Allen and BE Barry's sidekick. He decided to travel in time to join Barry in the 20th century, but made a decade-sized mistake in his calculations, ending up in the nineties. He went to the Flash Museum and witnessed an exposition about Flash fighting Zoom. While in the future Zoom's name was lost to history, here everyone knew his identity as Eobard Thawne (in pre-Crisis, they also knew it in the future, he just didn't care). Eobard could not believe that his idol, the Flash, would end up killing him, and went mad, convincing himself that he's the real Barry Allen. He was eventually defeated by Wally West, the new Flash, and sent back to the future,his memory destroyed. All that remained was his hate for the Flash, though for a reason he could not discern himself.
>Post BNEobard's body was resurrected and he figured out a way to "cheat" time travel ("the Negative Speed Force") and change history. He first changed his own origin story, making himself an actual professor of the Flash Museum, instead of a crook named "the Professor", still got defeated by Barry and dedicated his time travel to making Barry's life suck without killing him.
