Leni Loud (seasons 1-4)

"Leni Loud" is one of the main characters in 1st-4th season and the deuteragonist in 5th-present season of the Nickelodeon series The Loud House. She is 16-year-old (later 17) who works as an employee of Reininger's.

Why She Was A Nice Dimwitted Teenage Girl (Why She Rocked)

 * 1) Leni has a likeness to designing outfits and accessories to go with them, making them look pretty.
 * 2) At 16 (later 17) years of age, although she is naive and ditzy, she makes up for it for her beauty and kindness to balance all of that off.
 * 3) In the episode "No Spoilers", it's shown she is the only member of the family considerate enough within the family to be able to make the perfect surprise party because she pays attention to what people like.
 * 4) Although irresponsible at times, she is shown to be very compassionate to make up for that as seen in the episode "Cover Girls".
 * 5) Leni is one of the few siblings to prioritize helping her family get better, as opposed to getting away when the Loud family caught the flu in "One Flu Over the Loud House".
 * 6) She along with, Luna, Lucy, Lana, and Lily, is one of the nicest Loud sisters, especially for her favorite little brother Lincoln.
 * 7) She has a beautiful and cute design
 * 8) Liliana Mumy did an ultimately wonderful job voicing her.

Bad Qualities

 * 1) Like Lincoln Loud, she has started to become flanderized after Season 4, becoming dumber to the point she went to preschool in "Schooled!".
 * 2) She mostly has clumsy/accident-prone moments and a Butt-Monkey in the series due to her ditziness.
 * 3) She has being framed for stealing several scarfs from her department in "Crimes of Fashion" which Ms. Carmichael thinks she did this and fires her from her job, but after Lincoln and Clyde found out that Ms. Carmichael's son did it (having used said scarves as capes), Leni was re-hired by Ms. Carmichael, who apologized for the accusation.
 * 4) Even before her flanderization, she can be irresponsible and moronic at times; because of that, she can be easily taken as an advantage of someone else.
 * 5) She was out-of-character even before her flanderization in "Don't You Fore-Get About Me" where she impersonatored Lori to stop her from going to collage and was happy to ruin Lori's collage plans, although she does get called out and confessed, but didn't get punished for it.
 * 6) What's even worse, Dora Dolphin was uncalled for, just for voicing Leni in real life movie ALHC.

Trivia

 * Originally, she was going to be an 8-year-old, obese, pigtailed girl with brown hair, but Mr. Savino decided to make big changes instead.
 * Interestingly, Lucy Loud was the sibling who ended up being 8 years of age rather than Leni.
 * Her name ironically translates to "Bright".
 * Leni Loud was her named after Leni, a nurse in Franz Kafka's The Trial, who falls in love with the main character Josef K. despite his unexplained status as a felon.
 * Leni surely resembles Star Butterfly from Star vs. the Forces of Evil.
 * As of Season 5, she now attends 12th grade. In addition, since Lori has moved out to college, she is now in the new oldest sibling in the house, and she is the second Loud sibling to sleep alone following Lincoln.
