First chart :D
Have some of the characters of ReCode.
Gaster and Core!Frisk are both omnipresent in this multiverse and both are randomly visited by everyone on the Omega Timeline.
Klowell is an outcode re-created version of a Fell!Papyrus.
Blue, Nightmare and Dream have their universe named as "Safety World". The twins do not longer have their role as guardians, they are completely normal habitants.
And no, Dream is not posing like that just for fun, his actual normal posture is that one. The only time you will ever see him in two legs will be when he sleeps, showers, eats or is invited to a party.
ReCode belongs to me
Undertale belongs to Toby Fox
All original versions of them belong to their respective owners, I just created alternate versions of them.
