This is NOT asking which one is your favorite.
The question is which did you first read when he was officially called "The Flash" in a comic book story.

Choices are:
* Jay Garrick (Golden Age Flash) - 1st appeared in Flash Comics #1 (1940).
* Barry Allen (Silver/Bronze Age Flash) - 1st appeared in Showcase #4 (1956) / died in Crisis on Infinite Earths (1985) but later got better
* Wally West (post-CoIE Flash) - became The Flash at the end of Crisis on Infinite Earths. Disappeared by the end of Infinite Crisis, but later came back. (Then didn't exist when the New52 began, but came back in DC Universe: Rebirth)
* Bart Allen (post-Infinte Crisis Flash) - Became The Flash after Wally vanished and after Bart had suddenly aged as a result of events in Infinte Crisis. Didn't last long as The Flash. (But later returned as his younger version)
* TV/the CW version of The Flash (Barry) - had separate digital-first comic book (The Flash: Season Zero) that was based on the TV show version and was separate from the regular comic book continuity of the DC Universe.

ALSO NOTE: We're specifically referring to these characters being "The Flash", not their time when they went by other identities.
