I'm between stories, so it's complicated:
Rise of Prom had:
Rod
Manny
Mila
Wendy
Nes
Which is of course 5 people
The story is based on a comic I did, so offscreen characters count too, as they technically exist, but I simply didn't have time to properly add and/or simply show them:
Sherman's Squad: 5
Demetri's squad: 5
Ashleigh's Squad: 5
Angels: 10,000,000 (Though of course I couldn't fathom how many, there's quite a few seen flying around near the end)
Sherman technically will be missing 1, as Aliza later joins Rod/Nes' group. And they will remain at 5 as Manny unintentionally leaves it.
The new comic I might do just will have 2 MCs,
with their group maybe expanding to 3? But temporarily...
The other "group" is a league of superheroes which is however many is in the justice league...
Last but not least is UBERNATURA, which has technically one BIG group, but it's divided into whoever's BFFs and who's just a normal friend, to who's dating and/or basically spouses by now..
Empath
Lite
Azura
Shin
Are the main characters and the core of the bigger friend group, but most wouldn't even be friends if it weren't for them making and holding the group together..
Kristelle's group:
Robby
Payne
Gary
Bianca
Fast food group:
Payne
Gary
Bianca
Sammy
Disability group:
Actually I need to find their
names again in my notes..
I think it's;
Ashley and Isabelle (?) But
I'm not 100% about it...
Android/not Android group:
Ren
Luka
Shin and his siblings
Shin
Ritz
"Katy"
They become the main focus in the arcs they're in, and yes I should remember more, but geez that's a lot to remember
Girlfriends:
"Asuna"
Holly(?)
Platinum
(Might change Asuna's name, for obvious reasons and
ALSO can't be 100% of Holly's either... They actively become
Main characters too for the arcs they appear in. ) Um yeah, that's all the reoccurring friend groups, and most of their names... Fortunately the notes are safe-ish....
Also this is why I keep complaining about UBERNATURA it's a huge extensive amount of parody and very serious world building and intricacy. If I don't get help I might tone down a lot of the characters though..
