I'm imagining him as a Cryo Catalyst, since he probably lost the ability to use a sword after he got his ass beat. I get the feeling seeing a sword gives him bad reactions after that (considering he had Bennett, Eula and Traveler running at him with them and then got backstabbed...) so he prefers to just use his own power- although having a catalyst doesn't really do much outside of appearances, it can restrict him from using too much power at once and exhausting him, which is useful. He prefers to keep a distance in fighting instead of going in with the smack like half the other male catalysts do.

His fake Vision, which he uses to pass off his Cryo abilities (not like he really needs to cause literally everyone can tell he's a flower) is located on the back of his little overcoat thing. It's similar to Venti's where it splits into a pair of coattails at the back- the glowing thing on the back of Venti's is in the same spot as Rubedo's Vision.

He ties his hair up into a little bun, with one of the lantern-like thingamajigs hanging off it. Paired with the two on his braids he's got three lanterns, which smack into each other and sound a little like bells when he's running around. If you need to find him, just follow the sound.
