—XY, "Guitar Villain"
XY is a famous pop star and Jagged Stone's biggest rival in the music making business.
XY is tall with light skin, blond hair styled to stick forward, and blue eyes.
He wears a purple camouflage headband that is tied in the back of his head. His jacket is purple, having white with a thin black line in the middle cuffs, bottom, and collar, and he wears it over a white t-shirt with a low collar. He wears a light purple belt with a golden buckle, pale blue jeans, and gray tennis shoes. He also wears a gold chain necklace with a large gold "XY" symbol hanging from it.
XY is arrogant, vain, and rude, believing himself to be the best and looking down at anyone who isn't as popular as him. He carelessly insults his rivals in the music industry, and he doesn't take warnings seriously, even when they come from Ladybug and Cat Noir. When his life is being threatened, though, he freaks out and loses his overconfident nature.
He is good at making music that people enjoy, as he has amassed considerable fame. However, this is questionable, considering he planned to have a music engineer and hologram of himself to play a supposedly live concert.
XY doesn't like him very much, thinking that he is too "old-fashioned" to perform. When Jagged Stone as Guitar Villain comes to get revenge on him for insulting him in an interview on television, though, XY panics and pleads with him to spare his life.

- He is Chloé's favorite singer.
- His music mainly consists of beats and techno music rather than consisting of lyrics.
