Reacts

You were bored because you had nothing to do, so you came up with the idea of ​​bringing in some characters to react to other universes or their future, so you started preparing everything necessary.
(It can be a normal reaction to them, or a normal reaction to another franchise, or one where you combine two or more universes in a certain character)

You are a Multiversal Guardian who watches over different universes alongside others, but one day you had nothing to do and were bored, so you decided to bring in a franchise to react.
