(Updated) Where do these characters originate

Yes, John Doe, Noli, and 1x are real accounts, so myths can be both real or fake accounts, like guest 666 for example, he's not a real accounts. Also, yes, Mafioso is from Dream Game, but this version is the forsaken version and not the original version.

I know that 1x and John Doe are real accounts

and you forgot Jason. (Now as Slasher)

This is not really how you use Tiermaker but ok.

I’m pretty sure taph is from forsaken but I might be smartn’t

Why is news man here and the whistle occurence
