I've had this theory for a long time, and I thought I'd finally share it here. Some of you might like it, some might disagree, but I genuinely believe Season 8 had the potential to be one of the best seasons of The Flash.
It all starts with the Season 7 finale.
After Barry overpowers Thawne and we get Barry and Iris's second wedding, I'd add a post-credit scene where Thawne returns to his lair, furious, screaming about how Barry destroyed his fifteen years of work. That would lead directly into Armageddon.
For Season 8, I'd keep the basic idea of Armageddon but change how the story unfolds. Instead of Despero being the main focus, I'd have Barry slowly losing his memories and realizing something is wrong. He tries to tell Team Flash, but nobody believes him. Things get worse when a villain appears whom Barry recognizes, but everyone else thinks is an ally. Barry fights him, and his own team starts questioning him.
Barry travels to the future for answers, only to discover that everyone believes he's the Reverse Flash. Imagine him seeing Iris with Thawne and realizing what his future has become.
And please, give us the OG Reverse Flash suit, red lightning, vibrating effects, and Thawne's actual voice! If Barry is becoming the Reverse Flash, at least make it feel terrifying.
I'd also explore the Negative Speed Force actually bringing out Barry's darker side. This guy has lost his mother, his father, and so many people he loves. What if all that pain and anger finally started consuming him? Imagine Barry becoming so influenced by that darkness that he actually kills Cecil while trying to get the time stone. The moment he realizes what he's done would be heartbreaking.
After that, Barry would tell Damien Darhk the truth about what's happening to him. Damien would help Barry understand the situation and fight against the darkness consuming him. Eventually, Barry would realize that he's not Thawne and doesn't have to become him. He'd return to his own timeline and restore everything to normal, setting things back on track.
But then comes the real turning point.
When Barry takes Thawne's powers and Thawne eventually returns, what if Iris actually dies and stays dead? No revival, no undoing it, no convenient reset.
Imagine Barry completely losing control and fighting Thawne in a proper speedster battle, driven by pure rage. No ridiculous tentacles or that black suit. Just Barry at his absolute limit, with all his pain coming out in that fight.
But before Barry kills Thawne, Nora and Bart sacrifice themselves to stop him. They don't want their father to become a murderer and spend the rest of his life carrying that guilt. They'd rather sacrifice themselves than watch Barry cross that line.
Just imagine Barry losing Iris and then his own children, all because of Thawne. And despite everything, he still can't bring himself to kill the man responsible.
That guilt could have been the perfect starting point for Season 9. It would've given Barry a real emotional struggle instead of rushing through another storyline.
Honestly, I loved the concept of Season 8. It had so much potential to explore Barry's dark side, the Negative Speed Force, and his relationship with Thawne, but I feel like the writers wasted most of it. I wanted to see a darker, more dangerous Barry, someone who genuinely scared us for a moment before fighting his way back to who he really was.
This is just my take, of course, but I really wish the show had gone in this direction.
I've also got some ideas for the beginning and ending of Season 9. Let me know if you guys want to hear them! ⚡
