Firstly, that makes me very happy that you loved all that was listed. Secondly, how about naming your favorite from these categories just to make things easier, if it works:
Human: (Jordan, Giorno, Steve etc.)
Chiman: (Laval, Cragger, Eris etc.)
Outlanders:(Risotto, Formaggio, Illuso etc.)
Royals: (Brandon, Diavolo, Spinlyn, Scorm, Braptor, Sparacon)

Not a bad selection. You’re a fan of the God of Chima and his biggest worshipper. I should mention that, in future arcs, like about the time Fluminox and eventually Moonchild appears, Guido actually makes an appearance. In reality the only Passione members to enter Chima are Giorno and Guido, since three of the Buccialati Gang-Stars were killed off while one disbanded.
I’m not sure if you’re aware, Brandon Avatar is the TRUE antagonist of Cavora Glory, since he used his Stand, Nowhere Man plus Giorno’s Requiem arrow to create and send the human cast to Chima. Brandon is basically Beta-Pucci; he’s if Akira Otoishi was a fanboy of DIO. The whole reason he created Chima is so he could end the Joestar-Cujoh line without leaving a trace. Since Giorno is technically the son of DIO, he thought that he has a stern hatred towards the Joestars. But this was proven wrong, because Giorno don’t know squat about the Joestars. In response to that, during the second part of Cavora Glory, he creates self-inserts/ illusions of the extra Passione members from La Squadra and Le Elite, to form the Outlanders’ Thirteen to ally alongside the Outland Tribes. But that to, backfired. Then Moonchild happens, Brandon shows up, is killed off by NFGR and GER, and Chima is free from the fanboy’s grasp while Jordan and bros return home to their reality, before Jordan welcomes Giorno to the Joestar line. Whooh, that’s a lot to take in.
I’m actually surprised you said Eris was your favorite, the eagle and only female of the main Chiman cast. I thought you would something like Laval, Cragger, or maybe even Worriz. But I’m shocked.
Lastly about the Outlanders’ Thirteen. I originally wanted eight of them because there’s eight pawns in a chess set, and the Royals’ Stands are names after chess pieces. (KING Crimson, QUEEN of Stone Age, Lost Time BISHOP, Shadows of KNIGHT, and Crystal CASTLE). But I pulled off a proverbial Doc Brown and said “What the Hell.” The member’s of the Outlanders’ Thirteen are: Risotto Nero as it’s leader, Formaggio Invidia, Illuso Vanita, Sorbet Avidita, Gelato Sprecone, Prosciutto Pigrizia, Pesci Golosita, Melone Lussurio, Ghiaccio Rabbia, Squalo Carestia, Rigatoni Guerra (from the novel), Cioccolata Inganno, and Secco Pestilenza. Sadly, Doppio isn’t included. I just didn’t have the thought of including him. But anyways, nice selection.
