Is Wormzi a thing in CC? If so, how’d N and V take it?
Oh, Wormzi is absolutely going to be a thing - it isn't called "The Crawling Chaos" just for the Lovecraft reference ;)
It's not going to be just Uzi either - there's going to be so many worms in here. Worms for days.
As for how everyone reacts:
At the start of the story (which picks up about three-ish months after the show, for context), the Dapper Trio all know that Uzi has been having corporeal instability issues, and have been trying to help her work through it/figure out what's causing them and how to stop it (Uzi discovering the inefficiencies in N and V's designs and deciding to do something about it is an outgrowth of this). Critically though, no one knows Uzi can become a worm yet, including Uzi herself - she suspects she can do that, but isn't really keen on testing those boundaries and is mostly just trying to figure out why she randomly glitches out and explodes into a cluster of crab claws and peering camera eyes sometimes.
Then some Shenanigans happen and it becomes pretty clear that she's going to need to start testing those boundaries in order to get a handle on her new robo-divinity and prevent said shenanigans from happening again. It's all very "repression is not the solution you think it is."
N takes this in stride pretty much instantly - this is just another aspect of Uzi's eldritch space magic, and come android hell or high water, they're going to figure it out together. Boy is nothing if not committed. Plus, well... he'd be lying if he said he didn't think Uzi having the power to turn into an eldritch centipedal machine god was kind of hot.
After all: we are, as a fandom, united by the sacred wisdom that N would still love Uzi if she was a worm (and vice versa).
V, in contrast, is more paranoid. She's terrified that something will go wrong and either the Solver remnant/ghost/thing in Uzi's mind will take over, or worse, in trying to contain that remnant, Uzi will go somewhere she can't come back from and become something even worse than the original Absolute Solver (an Uzi without any morals, driven by nothing but all-consuming hunger - terrifying). But, critically, as difficult as it is for her V's actually going try to voice her concerns this time instead of trying to gaslight gatekeep girlboss her way through things. She's let herself be ruled by her fear before, and it emphatically did not end well, and she's learned from that. She cares about these goobers more than she'll ever admit trusts N and Uzi, and she's going to stick with them and help out in her own way. And probably complain about it when they do something dumb or remind Uzi to eat again - but hey, someone has to be the sensible one in this polycule found family. If nothing else, she can keep Uzi from trying to experiment with eldritch monster transformations inside the bunker.
Uzi, for her part, agrees with V's paranoia (now that V is actually trying to explain herself). As rad as having a thousand extra arms and a bunch of holoprojector eyes can be, this is something she really would rather have left in a box and not touched ever. Unfortunately, she can't just leave it in a box, and Uzi "Godeater" Doorman isn't one to back down from a challenge. She's been presented with a new problem, and she's going to solve it, one way or another.
Plus, there's a surprising number of fringe benefits: among other things, it turns out eldritch machine god is actually surprisingly comfortable to sleep on (if you're a robot, anyway).
