Let's just say that X-Parasites mimicking the Mawkin did take off in the ships stationed at Hanubia, what's suppose to be next that won't feel completely repetitive? The only route I would be interested in is if Raven Beak's actions to allow the X-Parasites to be free on ZDR leads to the central collapse of the Galactic Federation, where Samus basically is put on the world that is featured in many of Other M's cutscenes to attempt to save as many lives as possible while also trying to end any further X-Parasite infestations coming to other worlds. It would have to end there though, as I do think having the X-Parasites around again after Metroid Dread creates another Phazon situation where the threat needs to have a written end in spite of the possibilities of such a threat to still be around. If they make it back, it'll feel like there will always be a possibility for the X-Parasites to continue to be a threat in some form, like with Phazon via Phaaze and the possible existence of multiple Phaaze. It wouldn't end unless it forcibly comes to an end. Phazon got written out as a potential threat with Corruption's ending, which was doubled down on by Federation Force. I see the same occurring for X-Parasites if their story isn't over with Metroid Dread, and I do hope that it is over. Like I said, if the missing Hanubia ships are a hint at what's coming next, I hope it's more Raven Beak, clone or real, rather than the only alternative in the X-Parasites returning. Raven Beak doesn't have to return exactly as he is in Dread. Give him a new armor suit and new weaponry, maybe wield (and dual wield) enhanced elemental spears as a nod to the choice weapon type of the Mawkin Tribe (and their X replications).
