Clyde McBride is a main character in The Loud House.
Clyde is an only child and Lincoln's best friend. He has two dads, Howard and Harold, who tend to his every whim and are always there for him. He and his dads own a vicious cat named Cleopawtra and a friendly kitten, Nepurrtiti. Clyde has also mentioned having a grandmother. He and his dads live in a fancy single-story house located across the street from the Loud House.
According to an Instagram post from the production crew, Clyde is Howard and Harold's adoptive child.
Clyde is awkward and nerdy, but sweet and supportive at the same time. Lincoln can always count on Clyde to help him with a plan. Like Lincoln, Clyde has a passion for comic books, video games, and science fiction movies. He is also a cat lover and owns two cats that he loves very much, despite how his oldest cat Cleopawtra always misbehaves.
Although he does not seem like it, Clyde is quite intelligent. He knows how to do taxes and about table manners as seen in "A Tale of Two Tables" and knows how to take care of babies. In addition, he seems mildly rich through his parents, given his nice house and lifestyle as shown in "Attention Deficit" and "Roughin' It". He is socially inept, but ultimately a very friendly and kind person. Clyde is patient and enjoys the company of all of Lincoln's sisters.
Clyde has many fears, allergies, and health issues. He has asthma, which requires him and his dads to carry an inhaler everywhere. According to his parents, he cannot consume meals with too much sugar or orange juice with pulp. Clyde is allergic to all kinds of nuts, especially peanuts, and has some form of gluten intolerance (possibly non-celiac gluten sensitivity). "Dance, Dance Resolution" shows that he suffers from acrophobia, a fear of heights, and can show severe signs of altitude sickness because of it. Clyde sometimes experiences panic attacks; when he does, he hyperventilates into a paper bag that he carries with him at all times.
Clyde is a huge fan of Blarney, the show's version of Barney the Dinosaur as seen in "The Price of Admission". He knows all of Blarney's songs by heart. He also owns a bunch of stuffed animals that keep him company. Clyde has his own laptop and a white noise machine in his room. "April Fools Rules" shows that he has a baseball trophy, possibly passed down from Harold (who used to be a baseball player).
A running gag on the show is Clyde's crush on Lori, which borders on obsession. Seeing, hearing, or even smelling her causes him to freak out, bleed profusely through his nose, and act like a malfunctioning robot in some cases. He occasionally faints as well. Clyde has candid pictures of Lori and treasures things she gives him or has touched.
"Clyde is Lincoln's best friend and wingman. As an only child, Clyde is jealous of Lincoln's full house and is always willing to play his part in a crazy scheme. He has a big crush on Lori and can't act normal when she's around. Clyde spends so much time at the Loud House; he's almost an honorary sibling!"
Clyde is an adorable dark-skinned African-American boy who wears circular glasses with thick black rims and blue-tinted lenses. He has freckles and black hair styled into an Afro. Just like Lucy, his hair always has a bright outline (although his is white and Lucy's is blue). He is normally seen wearing black pants, and a yellow-and-blue striped shirt with a white collar. He wears black tennis shoes with three white stripes, and white laces on each.
Clyde's sleepwear consists of a blue nightshirt with a white collar, and a pair of matching pants. Howard has mentioned that Clyde also owns feetsie pajamas.
Clyde wears glasses. They look nearly identical to Lisa's in design and color scheme. However, Clyde's glasses are somewhat more oval-shaped and less thick. The color of the lenses is a lighter shade of blue than Lisa's.
Clyde very rarely removes his glasses. He has been seen without them in "The Waiting Game", "Roughin' It", "A Fair to Remember", and "Kick the Bucket List". His actual eyes are very small pupils with bags around them. The title card of "Baby Steps", which features Lincoln and Clyde as babies, implies that Clyde has needed his glasses since he was a baby.
Alternate versions and alter-egos
At the end of the episode "One of the Boys", Lincoln is sent to a second alternate universe in which every character's gender is swapped. A female version of Clyde is seen in a photo, alongside Lincoln's female version, Linka.
Girl Clyde has long hair with a blue ribbon in it. She wears a yellow short-sleeved dress with a single, horizontal, white stripe on the middle. She also has glasses identical to Clyde's and purple hoop earrings similar to Leni's red ones. It can be inferred that Girl Clyde has a crush on Loki Loud, the male version of Lori, and has two moms (female versions of Howard and Harold).
This version of Clyde eventually ceases to exist, as it's revealed the entire ordeal is just Lincoln's dream.
Clyde is a fan of the Ace Savvy comic books, just like Lincoln. Lincoln and Clyde have cosplayed as Ace Savvy and his sidekick, One-Eyed Jack, respectively. In the episode "Sleuth or Consequences", the boys dress up as them for a comic convention that they ultimately never attend.
In the comic Deuces Wild! and the corresponding short, Lincoln and Clyde pretend to fight a giant gas monster as Ace and Jack. They are joined by the sisters' superhero alter-egos at the end of the comic.
