I have an idea:
Instead of having Nintendo guests, we could establish Nintendo as company in Projext X Zone like Capcom or SEGA.
It won' be an Issue.
Thats what most of this thread has been running with. lol
Two of the three houses house leaders
Pit teaming up with Valkyrie
Those are the pair units i would be down with.
Akira howard (Astral chain)
Itsuki (Tokyo mirage sessions)
Would be the solo units i'd be down with.
As for the other companies, characters i would like to see:
Star force Megaman/Harp Note (Megaman Starforce)
Sakura and Kamiyama (Sakura Wars)
Joker/Makoto (Persona 5)
Aegis (Persona 3)
Alex (Street fighter 3)
Masaki (Super Robot Wars OG)
I'm surprised Masaki wasnt in either X zone 1 or 2, considering his entire schtick was that he travels throughout the alternate realities of Bandai Namco crossover titles and half the time we see him in SRW it's the same guy, there's like 2 Masaki's running around, one from the OG timeline who has met guys like Spike Spiegel and Heero Yui and the one from the SNES timeline who came back for SRW30.
