AU where Savitar, being Barry Allen's variant, kicks Zoom and Eobard's butts in the s9 finale
Better idea than canon ffs. Also, I do not know Sav as well as I know normal Barry so I apologize if I get his characterization wrong
He does side with the bad guys at first (I am not calling them the Legion of Zoom. who approved that shit) but ultimately plans to betray them soon as he gets what he wants/needs; changing the future enough to bring himself back into existence (idk how it would work but alas, neither did the writers).
The betrayal would probably come a little early, working on the same side as those who killed his dad and mom respectively would understandably be diffcult; and Savitar doesn't hold back like Barry. I actually think it would happen when Thawne goes after Nora (XS), I say that cause I really don't think even Savitar would try to kill his own daughter without reason; so when everyone runs off to fight, he would go after *checks notes* Allegra instead (as someone he has no connections/attachment to) and put her out of commission one way or another since it's confirmed (how? WHO KNOWS *screams*) that he knew who she was.
So Thawne goes after Nora and Sav decides he won't let that banana bastard hurt or kill anymore of his family (whether she's technically his kid or not) and stops him. Thawne of course gloats about how he {as a version Barry Allen} won't kill him. They fight and he lets Thawne get a few hits in for fun-- then Savitar gets to see that sweet look on his nemesis's face when he realizes who's faster, and stops holding back. The first 'fight' between Savitar and Barry in season 3? Yeah picture that but a lot more brutal and somehow more personal. Then, once Thawne is thoroughly beat to hell; Sav reverse flashes him and runs off to fight the other person who once destroyed his life.
He runs through the tunnel just before Zoom would have killed all the officers (since Khione and Mark are already knocked out if not dead-- this is what happened. don't even.), and does it without his suit so Zoom will chase him (cause all he'll see is yellow lightning). Of course, once they get to a new location and see each other face to face; Zoom gets in a quick gloat about how they really were the same after all. Savitar lets him have that; it's not true + will make it all the better in a few seconds. Same with Thawne, he lets Zoom get a few hits in, maybe even feigns fear-- and then Sav fucking obliterates him in a 'fight' that parallels the one in Enter Zoom. Hell, he should break Zoom's back for extra funsies. We get a scene similar to 2x23 where Zoom says Sav won't kill him; but this time, he does.
Things go mostly according to canon from here. Eddie absorbs all the NSF users lifeforce (or smth idk what that was man), and Savitar ends up going with it. He doesn't accept this 'death', but there is a brief moment of catharsis with the revenge before he's once again erased from existence.
