Mm. Oc rambling again: Phishbone Edition since I don't talk about him enough.
Phishbone was made with all intents abd purposes to be like if Dream and Error were one guy abd also like puzzles (and were also a papyrus).
Phish loved his brother Sans, and he loves all of his other, more multiversal, brothers. Even if they're not anything like his brother (Ink, Swap, etc.) and even if they are too much like his brother in ways he never saw (Dust, Killer, Geno, etc.). Even if they aren't even technically his brother at all, (Dream, Nightmare, Fresh, etc.). In all cases, he loves very widely and very deeply, but especially his brother. No matter which version he's facing.
So, when he learns that it's versions of his brother who are the most beloved, the ones who are causing all the turmoil? Well, who better to calm them down than the little brother who always made sure his own big bro was stable? And with his brother, asking to play a game or solve a puzzle always worked.
He has the power now, thanks to the souls he has custody of (Soul Magic infused in his Puzzle Cube), to mediate conflicts the way he's always wanted to. Maybe he'd make some friends along the way, too!
And he does. He's very good friends with Ichor (longstanding oc of mine) who is like his brother in a lot of ways, but expresses his feelings much more openly. Apparently he was hurt either way, so he chose not to hide away. They often play games, and visit new universes together. Ichor is sad, but Phish loves him anyways.
There are others too. He gets along very well with the Outertale siblings, often visiting to hang out with them. Chesstale is a place he is in VERY often. He meets ppl.
And I've lost motivation so this is where I end it but Phishbone is just a silly guy.
