Based on my Final Descendent story. Frost Is not on good terms with Y/N and is doing his own thing. He's with some friends and they've called themselves the Cold Squad.
The Cold Squad all followed GB as she walked into a fancy house on a cliff side.
GB: Welcome to my home you guys.
Y: Nice place. So this is where you've been?
GB: Yep. I found my new home.
Frost: I presume you're going to want us to leave after a bit.
GB: Nah stay as long as you need I got the spare bedrooms. In fact I was gonna ask to join this little group thing you've got going on.
Hunter: New friend?
GB: That's right lil guy.
Frost: Sure, we don't mind.
GB: Nice. Also I needed to show you something, come with me.
They followed her once more as they moved into the garage, various pieces of technology were being worked on. There was also a whiteboard with notes on it. It spoke about how certain things in the universe have a cyclical structure and repeat themselves, one of these being the Y/N squad. So apparently there will always be one.
GB: Does Y/N have a brand logo.
Frost: Yeah, it looks kinda like his face. Why?
GB: Look at this.
GB handed Frost A small box that had an engraving on the front.

Frost: This isn't right.
Y walked over and looked at it.
Y: Yeah Y/Ns logo doesn't have the sparkle on the eye. It's just the face.
GB: Strange.
Frost: Wait this can destroy the multiverse.
GB: That's why I was intrigued. Y/N isn't the kinda guy to want to risk that. The device is meant to break the heart of the multiverse but not destroy the multiverse in the process.
Frost: What would be the point in that?
GB: Probably to take its power, DaFuqBoom was massively powerful and he only had a tiny link to it, I estimate he had about 0.00000000000025% of its power and he could take down cities with ease. He just never did.
Y: So there's a Y/N Wanting ultimate power?
GB: Probably. Does anyone recognise Tampered A? That seems to be the maker.
Frost: Y/N accidentally made a Tampered Timeline, but there was no Tampered Y/N.
GB: Weird. What would the A stand for.
Ys eyes suddenly shot open.
Y: Alt.
Hunter: That's my dad right?
Frost: Yeah. But what do you mean Y?
Y: Alt referred to himself as A on signatures and stuff. Tampered Alt.
