Mick Swagger is a recurring character in The Loud House.
He is a famous singer, and the leader of a rock band (whose name is still unknown). He has had his rock career for 40 years. Luna is a big fan of him, and sees him as her hero.
Mick is first mentioned in "Making the Case" by Luna, where she was imitating Mick's rock pose, ripping her pants in the process.
He makes a brief cameo in "Sleuth or Consequences", being pursued by Luna to obtain a lock of his hair during a concert. This was his first physical appearance on the show, but his first official on-screen appearance is in "Butterfly Effect".
Years before the beginning of the main series, Mick gave a concert when Luna was in the 7th grade. She assisted to the concert, which also was her first concert, and witnessed Mick on stage singing and calling out to her. She took the stage with him, and suddenly found that the world of rock was where she was meant to be. Since then, she has seen Mick as a hero in her eyes for giving her the inspiration to rock on.
Although he is a very famous rock star, he doesn't appear to be vain or selfish, instead he is a gentle and friendly man. He says that the most important thing about rock and roll is not being the best, but it is having fun. He likes to search for young talents, as seen in "House Music".
Mick is a tall man, with light fair skin. He has long brown hair that covers his eyes. He wears a yellow t-shirt that has a red circle print on it and a purple blazer, white pants, and black shoes. He also talks in a British accent.
