He only came into existence due to a temporal loop that is confuzzling when you really think about it.

Basically, Post-Flashpoint Future Barry encounters Savitar, who kills Iris.

Barry makes a butt ton of Time Remnants (Akin to Zoom) to face Savitar but Savitar kills all but one of them.

That now "expendable" Barry grows to hate everyone because they look at him like he's worthless and whatever.

ExpendaBarry finds the Philosopher's stone or something, then his armor, then travels through time propagating the lie that he is the OG Savitar.

He eventually goes to 2017 or whatever and kills Iris, starting the whole series over again.

From our perspective, it looks like this happens endlessly and without beginning.

But you could honestly trace the beginning to Barry messing with the timeline to create Flashpoint which makes this temporal pretzel happen. Wrong, Jay Garrick already knew about Savitar, and changes to time don't affect other universes, such as when Harry and Jesse came back to Earth 1 and didn't know about certain things.
