"Take your time for taking care of yourself. Happy recharge!"

He appreciates the love!

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.

I dunno my brain just thinks the doggies should just chill together while X and Sigma are doing something related to their job

Hehehehehehe, yeah

Or more accurately, dawg before and after he met his person.

Cinnamon, it her!!!

Tbh I've been meaning to post this but things happened and her doodle kept getting pushed back. At least I got to her now, she's such a sweetie.

Something or other, the FF! Au clones deserve love and comfort just as much as everyone else

If it helps, Nightmare didn't, and still doesn't, really care how Isoc treated him. He's not always there and behaves pretty kooky for the most part.

Nightmare remains under X's custody and is in a care facility X created with Iris, basically a psychiatric hospital for reploids. All of Nightmare's weaponry and dangerous programs had been removed beforehand so he's as close as he can get to a regular reploid, but he can still overpower you if he really wanted to. He doesn't seem to mind his alterations that much though and mostly struggles with his short attention span, memory problems, and desire to cause chaos. He's seeing a counselor for this and receives both individual and group therapy to address his issues. There's a debate on creating the reploid equivalent of medication to help soothe Nightmare's symptoms so perhaps one day he'll be stable enough to leave but that's a long way off.

Specifically how they'd get along/some ideas of your of their siblinghood with Levi.

The Blue Sister and the Oc sibs. I wonder how they'd get along

Since you're asking for their relationship to Leviathan specifically I'll try not to mention Harpuia, Fefnir and Phantom too much. Enjoy the info dump:

Opera takes after Roll's nurturing side so she gets along with Levi pretty well for the most part. They don't see each other as often as they want to bc they work in completely different areas so bonding isn't too common, but Levi always goes to Opera when she wants someone to vent to and aunt Roll isn't available.

Legato is pretty energetic and is always hanging off on someone. Unfortunately Levi doesn't like that very much and they both end up batting at each other like cats. Legato thinks it's funny meanwhile Levi finds it annoying, imagine them as a sassy older sister and a mischievous younger brother. You could almost forget they're cousins since they're each other's ride or die.

Acapella and Levi love singing together, so much so that they have a dedicated music room Rock built for them, complete with a program that lets them compose their own songs. They have lots of fun together but that sometimes gets in the way of work so they aren't paired up together as much as they'd like. Basically they're besties foresties.

Solo is pretty standoffish but they love gossiping with Levi. No secret is safe with them, they will judge all of your choices and mock you for every single one. The heckling is more minor with their siblings/cousins and non-existent with Rock, Roll and X, but everyone else is fair game. Beyond that though they're just generally chill and spend their time together doing their own things.

Serenade is the one Levi goes to when she wants to relax and decompress. They play games together or just vedge out, general self care stuff. Sleepovers are common with these two specifically and they usually talk about the ocean and cool marine life. Serenade once said her favorite fish was the goblin shark and Levi couldn't stop cackling.

Baroque is very affectionate so he always pulls Levi into the biggest hugs when she's feeling up to it. They go back and forth telling each other about their days, watch some shows they both like, rate how good or bad they were, y'know, pretty casual bonding. Despite the cheery front though Levi can tell Baroque is hiding something, she doesn't interfere though, she trusts him to put their family's safety above all else.

I actually wanted to use the entire color wheel and added 6 more guardians at one point XD

Crazy I know, but the idea was that Rock and Roll would be discovered by Neo Arcadia and rebuilt as emotional support units for the real X. It worked for a while and then it was decided that guardians would be made to protect the siblings using their DNA souls. X's guardians are the ones we all know and love, Roll has three guardians she named Opera, Legato and Acapella, and Rock has two guardians he named Solo and Serenade. The last guardian was made using the remains of Blues/Protoman, though no one except Rock and Roll really knows that, and was set to protect Rock.

Opera's color was pink, and her animal theme was an axolotl. I imagine she's the older sister of the group and helps Harpuia keep everyone else in line. She's very caring and is second in command when Harpy is down. Legato's color was orange, and his animal theme was a salamander. He gets along most with Fefnir probably and the two rough house a lot, it drives everyone up the walls bc it takes forever to get them to stop. Generally though, Legato's very loyal and enthusiastic. Acapella's color was yellow and her animal theme was a firefly. She's pretty bubbly and likes talking to people. Sometimes she gets the zoomies and darts all over the place, she tries not to crash into people but it's happened before and will again.

Solo's nonbinary and their color was cyan, their animal theme would've been a lobster. Way more chill than their cousins and can be prickly sometimes but still loyal to their family. Doesn't stop them from playing pranks on them though. Serenade's color was purple and her animal would've been an octopus. Very "go with the flow" kinda gal. Stays calm under pressure and is easy to talk to, of all the guardians she's the one that dislikes fighting the most.

The last guardian's name was Baroque, his color was white and his animal would've been a dog. He has a strong attachment to family and loves all of his cousins, uncles and auntie. Is probably the most rebellious guardian since he want's what's best for his family and can sometimes get in Neo Arcadia's way. Despite that he's still well liked by the general public so Arcadia can't do anything about it and he knows it.
