Explaining this!
The idea came from this ask of Mario confronting a higher-higher up Admin. Basically, the code that let's Guardians ascend to Admins once deemed ready and worthy enough.
The idea basically is one of these Admins (who we'll call Cluster for the time being, until I decide on a better name) comes to the Mushroom Kingdom as part of a check-in. To see how the Admins and Guardians of this universe are doing.
Cluster,, is immediately off-put by the fact that not only [575] (Domain) and [686] (Forum) are experiencing emotions, they're actually involved in the lives of their Guardians..
And they remember their past lives.
Cluster isn't exactly happy with this, having been the Admin that ascended them. But unable to accept the fact that it might be the reason why the memories didn't stay locked up, it instead blames it on the sorry state of the Mushroom Kingdom. It's disgusted and repulsed by the fact that characters from different games live in the universe and that there's so many recolors of the Avatar..
And then it stumbles upon the Code that oversees and protects the two Guardians of this universe, and it gets an idea. So what if it's manipulating what's basically a child? It's for the betterment of this universe. After it gets this code stronger, it'll use this code to reign in the Admins and the Guardians and fix everything. And so what if it's hiding its true identity to get closer to the code? It's just helping it get stronger, after all.
Lil Coding, meanwhile, isn't.. feeling the best. He feels like he's weak and his abilities are subpar, and he unfortunately doesn't really have anyone to train with. Even at their weakest, Domain and Forum are too powerful for him to even train with, and his dads have abilities completely different than his, and they still need to train so.. they're a no-go as well.
So when someone he can practically sense has power similar to his and introduces themselves as Cluster? A code similar to him? He's elated! Someone like him, maybe they can even train together! Cluster agrees to, but only if Lil Coding agrees to help it with getting rid of small viruses that are 'running rampant' in the Mushroom Kingdom.
The only caveat being he can't tell anyone about this because they might try and stop him from training with Cluster.
Lil Coding, none the wiser, agrees.
The main plot of the arc would be the gang having all their adventures, with Lil Coding joining less and less, joining Cluster in getting rid of 'small viruses'. Lil Coding unfortunately unaware that Cluster is simply hiding the citizens true forms with some bit of code twisting.
Lil Coding becomes more and more quiet, obedient, and generally a shell of his extrovert self throughout the main plot of the au. Cluster is extremely manipulative and gaslights Lil Coding at even the smallest sign of the Code wanting to stop. It pushes Lil Coding to his limit again and again, all under the guise of getting stronger.
Similar to the 10 Year Anniversary, FM and X both realize something is going on when recolors slowly start disappearing, and they head to the SMG4 gang to let them know. At the same time, everyone notices how different Lil Coding has become (over the plot, it's pointed out and even directly addressed, but Lil Coding always brushes it off).
It all culminates in everyone going to look for Lil Coding and finding him...
Just as Cluster commands him to use Rewrite (the equivalent to Iceshock in Deltarune) on a citizen 'not meant to be in the game'.
Cluster, seeing an opportunity, urges Lil Coding to use Overwrite.
He says he doesn't know how.
Cluster pushes forcefully.
Lil Coding insists he doesn't know how.
Cluster demands it.
Lil Coding snaps and uses the command, overloading his body with way too much energy in the process. In the surrounding area and even further, any character not meant to be in the game is overwritten and 'sent back to their game' (in reality, they're sent to a pocket dimension where Cluster will more than likely turn them into code to empower itself and other Admins).
Thankfully, Forum and Domain get there before Lil Coding uses the command and gets everyone out of the radius. But now it's a race to get Lil Coding away from Cluster before the other Admin makes him stronger and forces him to use Overwrite again,,,
