THE FLASH SAVITAR THEORY
Jay sacrificed him in the speed force for Wally so he could return to team Flash.This would drive him insane and want to get at team Flash for making him suffer eternity.But I kind of don't want this to happen because I like the legacy of John Wesley Shipp as the Flash.I will give this a 4/10.
So what if when Eddie was sucked into the singularity he got sucked into the speed force, that some he got powers and he suffered an eternity because he sacrificed himself for team Flash.The reason we may not have seen him since now could be scheduling issues, Rick Cosnett may not have been available so they have him on the show for the last few episodes.I will give this a 5/10.If Eddie comes back he will come back as Cobalt Blue.
Wally suffered a fate far worse than death which drove him scared.If he were Savitar he technically would give him his powers as Savitar created the philosopher's stone which Wally used to give him his powers.I think if something pushes Wally to offer the edge it would be the reveal that he is Savitar.It would be insane if this happened, but they won't write off Keiynan Lonsdale as a villain this fast.
There are a lot of theories that Savitar is the future Flash.The way this would work is Future Barry gets super depressed, maybe all his friends are killed, so Future Barry turns into Savitar to try to make Barry faster to test him or to end his life.Grant Gustin as an actor could pull off a complex role such as this.I will give this 7/10.
This is the most outlandish theory.But ginger Wally west from the comics could be Savitar.So the Reverse Flash changed to the original timeline when he came back in one, he created Barry becoming the Flash in 2014 and not 2024.So what if in 2024 there was a kid flash, the ginger Wally West, and he sacrificed himself to save team flash and now because of Flashpoint Ginger Wally West came back and now he is angry at team Flash for forgetting him and he want to end them all using the persona of Savitar, I will give this a 2/10.
