Luna Loud - Fat

Luna is very happy, wild, caring, and easily the loudest sibling of the entire family. What she likes most is singing, playing musical instruments, and being with her family.

Before she became interested in rock music, Luna was a shy, gentle and classy girly girl who loves classical music and used to perform a violin concerto. After her first concert, she developed an interest in rock music. She is a big fan of several rock groups, and her dream is to become a rockstar. She owns and plays both acoustic and electric guitars, with which she has proved to be a very good guitarist. Her skills aren't limited to just the guitar though. She also plays the drums, as well as other instruments, as seen throughout the series, like the violin in "Overnight Success". She sometimes talks with a fake British accent, especially when she listens to music; something that her siblings consider to be an annoying habit.

Most of the time, she can be found practicing with her guitar or listening to rock music. She sometimes gets angry and threatening with her fists. However, she mostly uses the vibration sounds of her guitar as a weapon to harm someone when she gets upset.

She will get upset if someone turns off her music, and in some cases, she will get agitated by her siblings. She sometimes gets downhearted when her family isn't with her, or when she upsets her siblings.

Luna has displayed romantic interest in her female classmate Sam Sharp in Season 2. Subsequent episodes depict Luna as having entered a romantic relationship with Sam. Luna's siblings are aware that Sam is a girl, and Lori considers it sweet that Sam and Luna exchange guitar picks. In the episode "Racing Hearts", Luna and Sam spent a whole day participating in a citywide scavenger hunt together, but to her and Sam's disappointment, they don't have that many things in common, however at the end of the episode they agree that while they don't have much in common, they can still discover new things about each other.
