Probably some shenanigans that they still remember him in his other form, and thus that cognition allows Morgana to fight.

she can carry her sword with her mouth?

you all know that morgana is a guy, right!!

Koromeowru-style

He coughs up hairballs and the enemy is like "Ew" and forfeits.

his*

I mean, I do

@IamThou *ahem*
also their forms in the metaverse won't be able being here , so this is maybe enough with this ... i think ?

Maybe instead Joker

Well they'll bring distorsions back somehow.

@pure-anon *relizes the topic*
fu- , why did i do this to myself

WELL I SEE THE AND SYMBOL IS STILL BROKEN
FUCK
Maybe instead Joker and Mona become the new Ken and Koromaru

I'd assume that some big bad would cause the metaverse to pop back into existence, or that wherever they end up will allow them to use their P Thief forms

Or they could set it before the ending of the game.

Make it a PQ thing where it makes no logical sense timeline wise and it retcons itself anyway
or have them just like
discover a different world like the tv world and be like
this is dumb who wants to go make cosplays of our old thief uniforms

I would imagine that if Morgana were to wander into any supernatural phenomena, he would probably take on his mascot-like form again. He also still has a Persona either way.

The Metaverse may be gone, but there's still plenty of Collective Unconscious to be had out there. Hell, the TV World still exists, or they could just come up with some new cognitive dimension for a new spinoff

@Hibiki well , i didn't play the p5au yet , so i must cheek it out for myself

@Kala-Nemi yup just like kuma

Morgana will come back as a fear induced illusion this can allow him to be somewhat out of place just he get into death battles with others.
