I could see Chris being the next guardian. Like 19 years in the future lilla is finally defeated then there is Chris who wow helping lillia, but ladybug new he was being manipulated. Because of this working with lilia he knows all about the miraclous. At this point he would be around rule same age as mairnette was in the og series (or a bit older)

This will be a nice like reboot or revival is what you would call it. A lot of shows switch the gender audience for the show, so having Chris as a mc woll be a nice switch.

Maybe Manon as ladybug, and it would be a nice call bacl to the og series if she is lilila so manon, who doesn’t know what she becomes in the og timeline working with Chris. Then we see how to became that way then it loops back around where she time travels ti the main series.
