So as we're getting closer to the end of the Multiverse Saga, there has been a lot of speculation as to what comes next. It is almost universally assumed that the next saga will be the Mutant Saga, with the X-Men taking centre stage. Naturally, everyone wonders what the saga-spanning threat is. Originally we had Thanos gradually taking control of the Infinity Stones and now we have the degradation of the multiverse leading to Doctor Doom's intervention. So what next?
Some have just put names forward. Magneto, Mr Sinister, Apocalypse. Magneto for me is not the kind of villain to fill this role, he is more of a Loki, mostly a villain but sometimes an ally. Mr Sinister I'll come back to, because I do think he'll be involved. Apocalypse for me would be the safe and lazy choice. Yes he's a great villain and could absolutely fill this role, but I feel like it would be too similar to Thanos. Also, X-Men 97 has already heavily focused onto the character and it would be a little strange to tread the same ground.
So, Orchis. They're a bunch of mutant hating extremists from various organisations like AIM, Hydra, Trask, etc that came together to focus on their shared goal of destroying mutants forever. They use various means for this, but the main one is AI/machines. Taking the AI in the Sentinels and upgrading it to the point it becomes self aware, culminating with Nimrod, the big guy in the picture. With Nimrod, if you're not familiar, think Ultron but with way more anger issues and a special hatred for mutants in particular. In the comics this is based on (House/Powers of X) due to spoilery reasons the X-Men are absolutely terrified of the day Orchis will create Nimrod. It's like a ticking time bomb they know is coming. This to me could be part of that saga-spanning dread. Remember the "fine, I'll do it myself" post-credit scene with Thanos? Imagine something like that, but instead it's a scene of Nimrod in assembly and ending with his eyes turning on menacingly. After some previous set up as to why this is a big deal of course.
I also think Orchis work well because arguably they've already had their origin story started. A certain technology used by a certain organisation in the new Spider-Man film is potentially right up their alley. The organisation of Orchis coming together as they gradually recruit villains would make for a great narrative connection for the early days of the saga too. Mr Sinister would be an obvious choice for the first to be recruited (I would just have him take the place of Doctor Stasis, as it would be simpler for the movies).
Some people may be against jumping into the Krakoa Era so soon though, and while personally I'd be happy for them to jump right into it, I do get why some wouldn't want this. However, you wouldn't have to do that anyway. Orchis still make sense as the villains outside of the context of Krakoa. Personally, I'd love to see the Krakoa Era adapted for the saga but it doesn't have to be. We've seen comic storylines get mixed and moved around to better suit the movies before.
I have more thoughts, but this is probably long enough. That's my pitch. Thoughts?
