Loki Loud is the male version of Lori Loud.

Appearance- Like Lori, Loki wears a blue tank top, brown shorts, and blue sneakers. He also has two chin hairs. Unlike Lori's eyebrows, Loki's eyebrows are yellow instead of black.

Personality:

1. Loki seems to have the same personality as his brothers: unsophisticated ruffian. He is selfish, greedy, and very bossy around the others. He is also mean and abrasive towards Lincoln, and mocks him for Luke using him to clean the toilet, for Leon biting his thumb when he gets a "boo-boo", and teases him about his relationship with Ronnie Anne. He isn't the rudest of his brothers, but he is annoying enough.
2. However, in the world where he and the brothers have a sister named Linka, Loki and the other nine brothers are shown to be very caring and protective of their sister—in fact, Loki is the first of the brothers to ask Linka if she's okay after the brothers heard her screaming in the middle of the night.

Trivia:

1. He is the only Loud brother who has facial hair.
2. Unlike his female counterpart, Loki has blond eyebrows. He is the only Loud brother to have this distinction from his female counterpart.
3. His Polish name is Hugo, which means "Bright in Mind and Spirit" or "intelligence."
