Loni Loud is the male version of Leni Loud.

Appearance: Unlike Leni, Loni's blond hair is shorter, and his sunglasses aren't as circular. Instead of wearing a dress, he wears a light green silk sweater with a white long-sleeved shirt underneath, and dark blue jeans; instead of wearing sandals, Loni wears light green socks with white spots and brown dress shoes.

Personality:

1. He is goofy like Leni, but unlike her, he's not sensitive when his brothers get hurt and doesn't care about it. He laughs at Lincoln's relationship with Ronnie Anne and how he suffers physical pain. This contradicts the caring and kind personality of Leni towards Lincoln.
2. However, in the world with Linka Loud, Loni and the rest of the brothers are shown to be very caring and protective of her--in fact, Loni's the one who makes the offer of the brothers staying with her until Linka falls asleep after they hear their sister screaming in the middle of the night.

Trivia:

1. His Polish name is Honiek from Honoriusz.
2. His shirt is available in game "The Loud House Cartoon Creator".
