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, and he is shown to have a goldfish in "Purrfect Gig". He and his dads live in a fancy single-story house.
Clyde is awkward, caring, nerdy, 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 the fact that his oldest cat Cleopawtra always misbehaves.
Clyde is quite intelligent beyond his years. 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 because he learned about it from magazines in Dr. Lopez's waiting room. 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, since he gets lonely with being an only child.
Clyde is very neurotic, cowardly, cautious, and worrisome. 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 certain kinds of nuts, but not peanuts, however, as shown in "Snow Way Down", his dads are afraid he might later develop a peanut allergy. He is also sensitive to gluten (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 often panics and overreacts; 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 many 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). He also possesses both a humidifier and a dehumidifier as shown in "Overnight Success" and "Pasture Bedtime".
A running gag on the show's first two seasons is Clyde's unhealthy and obsessive crush on Lori. Seeing, hearing, or even thinking about 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. In his closet, Clyde has a shrine filled with candid pictures of Lori and treasures things she gives him or has touched or he has stolen from her. Clyde also sends Lori gifts, as seen in "Change of Heart", but Lori stores Clyde's gifts in a box. Sometimes, Clyde tries to sabotage Lori and Bobby's dates, but always fails and ends up making their love stronger. In the third season, this gag comes up a lot less frequently. It's possible that Clyde has finally managed to keep his excessive behaviors around Lori under control thanks to Leni's lessons. Despite this, Clyde still feels something for Lori, only that he does not prove it and does it now in a less obsessive way than in the past. After the third season, Clyde's crush on Lori seems to have disappeared definitively, as he has since had crushes on Stella in her introductory episode, and on Emma and later Chloe in "Brave the Last Dance". Meanwhile, Clyde and Lori seem to have become good brotherly friends, as shown in some later episodes and also in two official comic books "Loud and Proud" and "The Struggle is Real".
Clyde 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 footsie 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 rarely removes his glasses. He has been seen without them in "The Waiting Game", "Roughin' It", "A Fair to Remember", "Kick the Bucket List", "Be Stella My Heart", and "Game Boys". 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 his babyhood.
Alternate versions and alter-egos
At the end of "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 black 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. Girl Clyde might have a crush on Loki Loud, the male version of Lori, and she likely 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 to help defeat the monster.
In "Pulp Friction", Lincoln and Clyde create a comic book for a contest and imagine themselves in the roles of Ace and Jack respectively.
In "Tricked!", Clyde dresses up as One-Eyed Jack for Halloween.
In "Deal Me Out", Clyde cosplays as One-Eyed Jack, but then he and Lincoln are made fun of for cosplaying and wonder if they are too old for Ace Savvy. However, they eventually learn that one is never too old. Clyde also mentions to a little girl that Jack is the character he tends to cosplay as, and it's revealed that he dressed as Jack for Halloween at age five.
In "Crimes of Fashion", Clyde cosplays as Jack to assist Lincoln (dressed as Ace) in trying to determine why some scarves at the mall have been disappearing.
In "Recipe for Disaster", Clyde again dresses as Jack to help Lincoln (who is, once again, dressed as Ace) investigate something. This time, they are investigating the disappearance of Lynn Sr.'s recipe book and the fact that some frozen dinners have the same recipes as Lynn Sr.'s food.
In "Kings of the Con", Clyde cosplays as Jack at a convention, along with the Loud children, who cosplay as Ace and the Full Deck.
In the game Ace Savvy on the Case, Clyde cosplays as Jack on his way to a convention.
In "White Hare", he appears as a beaver named Danny in Lincoln's dream.
Danny is a big brown beaver with a blue and yellow striped shirt. Danny is similar to Clyde in every way: awkward, caring, nerdy, sweet, and supportive at the same time. He also seems to have an unhealthy and obsessive crush on Betty similar to Clyde's crush on Lori.Like Girl Clyde, this version of Clyde also ceases to exist since it was just Lincoln's dream.
