Albert (more commonly known as Pop-Pop) is a recurring character in The Loud House. He is the maternal grandfather of the Loud kids, father of Rita, and father-in law of Lynn Sr. He lives in a nursing home.
In "Cover Girls", he makes his first on-screen appearance. He makes a video call through the computer to talk with his grandchildren. Because he wasn't using his glasses, he couldn't clearly recognize the Loud children, who were dressed up like their other siblings.
In "Raw Deal", he is mentioned by Leni, when she says that she cannot wait to see Pop-Pop. Lincoln corrects her by saying they're going to see a geyser, not geezer.
He has a major role in "The Old and the Restless". He moves into the Sunset Canyon retirement home, where he is under the supervision of a strict nurse, named Sue, but he and Lincoln go out for a fun time. At first, Lincoln is happy to have a fun time with his Pop-Pop until he realizes they need to get back to the retirement home before curfew, or he'll be kicked out. When it's too late, the other senior citizens stand up for Albert, and Sue lets him stay. Albert thanks Lincoln for the fun day that they had together.
In "Brawl in the Family", Lincoln mentions that Lola snores as loud as Pop-Pop.
In "Room with a Feud", Lisa states that she invented a computer match up for Pop-Pop to find a soulmate, but he was not ready for love again.
In "Spell It Out", the Loud Family (excluding Lucy) visit him and watch him play shuffle board, which he ends up winning, and his grandchildren lift him up, while chanting his name in celebration.
In "No Spoilers", he attended his daughter's birthday party.
In "Not a Loud", he was called by his daughter to watch Lori, Leni, Luna, Luan, and Lynn while she delivers Lincoln.
In "Tripped!", Rita mentioned that he taught her how to fly a plane from his experience in the military.
In "Head Poet's Anxiety," Albert is present when Luan does her comedy at Sunset Canyon. He is later present when Lucy do her poetry at the Royal Woods Theater.
In "Ruthless People", Lynn Sr., Lori, Luna, Lynn, Lincoln, and Lola stay with Albert while their house has termites. Later, he is on the cruise which Sunset Canyon Retirement Home rent out along with Rita, Leni, Luan, Lucy, Lana, Lisa, and Lily.
In "House of Lies", Luan mentions that she regifted someone's gift to Albert.
In "Predict Ability", Lincoln mentions that Albert used to wear a kilt.
In "Driving Ambition", Lori reveals that her golf clubs used to be Albert's.
In "Racing Hearts", he and Myrtle pair together for the Royal Woods Astonishing Quest.
In "Cooked!", he can be seen during Leni's bingo game promotion.
In "Present Tense", he and Myrtle appear on a picture inside Lynn Sr.'s scrapbook.
Albert is a burly man, with white hair, and a large tuft of his hair that sticks up, much like Lincoln's hair. He also has gray mustache and thick gray eyebrows as well. On his right forearm, he has a tattoo of an anchor.
He wears a white button-up shirt, blue jeans with a black belt and orange suspenders. He also has glasses hanging on his neck when he's not using them.
He loves all his grandchildren and likes talking to them and hanging out with them. He loves adventures, sport activities, and eating spicy food. Because of Sue's toxic control, he lost his self-confidence, but Lincoln proved he's still fit, despite his age. He was grateful for this.
