Hi friend! Idk if you still want to do this or not but I would LOVE age regressor content for Erik Lehnsherr from X-Men (like, him as the regressor) and/or age regressor Charles Xavier
No pressure but just wanted to ask bc I saw your post!
Hullo hullo, now, I have barely any thoughts in regards to regressor Erik and Charles but I shall try and suffice!
Headcanon: Little! Erik is often nonverbal and can commonly be found hiding behind Charles.
Erik knew he regressed, after what he had been through it was obvious his mind decided to revert him mentally to an age filled with love, care, and safety. However, he was never able to indulge in his headspace due to his constant movement of hunting down the scientists who hurt him and millions of others. That was until he met Charles Xavier, the first ever mutant he encountered and learnt he wasn't the only one with a mutation. It was the first time he had felt love, care, and safety, all positive triggers to his regressions.
The first time he regressed with Charles, he remained silent, following the man around without much purpose other than to stay with him for protection. It didn't matter what the telepath was working on, he persisted in staying by his side, staying silent through the questioning and concerned looks directed his way by Charles.
"Erik? Are you quite alright?" Were the first words spoken by Charles when he regressed for the first time in his presence. Erik always remembered his first encounters with people, always preferring Charles' compared to others. Despite his lack of words and sudden clingy nature, Charles chalked it up to a particularly bad day where memories plagued the metal-bender's mind and the man wanted nothing more than comfort. "I see.. well, stay as you would like, I don't mind the company."
And then, it happened several times after that, with Erik finding Charles and clinging to his side despite the weird looks from the other members of the mansion. Charles had grown used to the behaviour, continuing with whatever activities he was doing, whether it was a light bit of reading, a particularly challenging puzzle, or simply working on paper-work for a reason Erik still doesn't quite grasp. "Hm... imagine you want to tell someone how many books you've listened to me read you, so you write it all down. Well, that's what I'm doing except with more boring things like a house and car. We use special papers to keep track of things so nobody forgets and everyone knows what's happening. Oh, you still don't understand, do you?"
Once Erik accidentally knocked over a vase and Raven had teased him that Charles wouldn't be happy with him and he would no longer be Charles' favourite anymore. He had held back tears as he listened to her words, unable to differentiate the difference between a joke and seriousness. He had gone and hid himself somewhere in the mansion, somewhere Charles wouldn't normally look as to avoid a scolding. It didn't matter though, Charles found him and frowned until he learnt that Raven had teased him about the broken vase. Erik would never admit it but he had leapt into Charles' arms when the telepath had confirmed he was still his favourite.
