The Miller Family, known as Jeff, Carly, and Ryan are the major antagonists from the Nicklodeon show The Loud House, first appearing as the main antagonists in the episode "Family Bonding".
Jeff has light skin, a long pointy nose (similar to Lynn Sr.'s), long brown hair and thick, brown eyebrows. He wears a light blue long sleeve collar shirt, with white pants, black belt, and light brown shoes.
Carly has light tan skin, a small pointy nose, two pairs of eyelashes with three on each eye, long blonde hair in the form of ponytail, pink earrings, and orange lipstick. She wears a white sleeve shirt, with blue jeans, and red high heeled shoes.
Ryan has light tan skin, blonde hair in the form of a pompadour and glasses. He wears a short sleeve white shirt, with brown pants and black belt, and dark grey sneakers. Ryan also have the same body type and age as Lincoln.
All three of them have an orange sweater tied around their shoulders.
At first, Jeff, Carly, and Ryan show to be a normal happy family being nice and friendly. However, the Millers were only pretending as they were revealed to actually be evil and willing to make Georgia peaches the best in the world, working for S.U.S.P.E.N.S.E., no matter what.
The Millers were sent by the organization called S.U.S.P.E.N.S.E. (Secret Underground Society of Peach Entrepreneurs Nixing Sour Exports) to begin a plot to dispose of the world's cherries starting with Royal Woods. They moved into a house next door to The Loud Family. However, Lincoln and Clyde became suspicious of them as the boys discovers the Millers were putting together a giant machine in their attic, he tries to warn his family but they refuse to believe him since he and Clyde have always had a habit of accusing the new neighbors whenever they move into Royal Woods causing him to prove them wrong.
For the past few days, Lincoln and Clyde proceed to spy on the Millers. Jeff meeting up with a woman in a trench coat and obtains a book on how to grow Georgia peaches from the library. Carly getting mad at Flip that she hates cherries. And putting a little microphone on Ryan's slice of pizza and eavesdrop on a conversation between him and Lynn Loud, where he says he'll be busy doing other things, including taking out the trash.
During a welcome barbecue party, Lincoln is caught in their home because of Lola (who probably had her suspicions) finding out about his infiltration from Clyde. When he told them everything he and Clyde found out, the Millers played dumb as they cover up their motive by stating that they work for a weather organization causing Rita & Lynn Sr. to make plans to talk to Lincoln about boundaries and then ground him for breaking and entering. When Clyde calls up Lincoln to ask if the mission was a success, Lincoln declines and declares the mission a failure. When Lincoln tosses his walkie-talkie, he unknowingly hits a button on the weather console that reveals a secret room with a machine ready to destroy all the cherries in 20 seconds.
Rita, Lynn Sr. and the girls react in horror as The Millers reluctantly admit they're actually a family of spies working for S.U.S.P.E.N.S.E., meaning that Lincoln and Clyde were actually telling the truth the entire time. Lincoln was able to beat the Millers and deactivate their machine before it could begin destroying the world's cherries. Before The Louds can arrange for them to be handed over to the authorities, Ryan used a peach-shaped smoke bomb to make their get away. They most likely return to S.U.S.P.E.N.S.E., all thanks to Lincoln that they had failed in their mission.
- Previous antagonists of The Loud House were jerks and bullies at worst, but the Miller Family are actual villains.
- Lori was the only Loud who never met The Millers, due to her attending at Fairway University.
- It's unknown if they or anyone from S.U.S.P.E.N.S.E. would return in future episodes to get revenge on Lincoln for stopping their mission.
- Because they are spies, it's unknown if "Miller" is their real surname or if they are an actual family.
- The Millers are probably references to the Klopeks, a family in the 1989 black comedy film, The Burbs, as well the main antagonists. However, where the Millers were spies, the Klopeks are murderers.
- Jeff bears a striking resemblance to Lynn Sr.
