If your Rainbow Guardians oc were boss fights, which do you think would be most enjoyable, annoying, memorable? I suppose I'm thinking it like more a modernization of MMZ but can be anything.
And if one of them had a playable mode, who would it be? From the way you describe them Baroque seems almost fitting for the role of tritagonist in a like secret "true route" or something. But I wonder who you'd pick?
The original Four Guardians would probably each have a single playable level in "original modernization" story. With maybe an arcade style "Boss mode"
Not too sure about individual boss fights, but maybe they can team up with each other? I'll just leave the boss mechanics up to your imagination. If nothing else, X's guardians are mandatory fights since Zero's actively seeking X himself. Fighting Rock and Roll's guardians would be entirely optional and are more to get the full picture of what X went through during the Elf wars. Either that or they're secret bosses you can find in certain rooms throughout the game.
You bring up something interesting about Baroque and this "true ending," but sadly he wouldn't be playable. After seeing the aftermath of Zero's actions on X, someone who Baroque considers close family, it would make sense for him to keep Zero as far away as possible. Maybe not a tritagonist like you suggested, but an antivillain since he isn't aligned with Neo Arcadia or Zero. Baroque's entirely on his own side where he wants to keep his family safe and happy. X has admitted that he has mixed feelings about Zero and both resents and misses him. Baroque believes Zero has hurt X enough already and refuses to allow him to hurt his dear uncle anymore than he already has. Maybe near the end of this route, Zero realizes the gravity of the consequences of his actions. Realizing that reuniting with X isn't healthy for either of them. Maybe the "true ending" is where Zero leaves for good and X remains with his family to govern Neo Arcadia.
Honestly the only way I could see any of the guardians being playable is through minigames. Maybe if you get a high enough score, you find extra secrets.
