Chandler McCann is one of Lincoln's schoolmates on The Loud House, featured as an antagonist in a few episodes. He seems to be the most popular student at Royal Woods Elementary, but in actuality is a very conceited boy and a freeloader.
In Chandler's debut episode, "The Waiting Game" in the first season, he invites all of Lincoln and Clyde's classmates to his birthday party that he annually throws at the sewage plant where his father works, but ignores Lincoln and Clyde. Then, when he sees Lincoln getting free food and tokens at Gus' Games 'n Grub because he helped Lori get a job there, Chandler gets Lincoln to do all sorts of favors for him, taking advantage of Lori's generosity towards her brother. He eventually does invite Lincoln and Clyde to his party, but in the end, Lincoln, seeing that his sister has to work overtime due to all the favors Chandler coaxed him into doing, decides to skip out on Chandler's party and cover for Lori at the restaurant so she can go to the school dance with Bobby.
Two seasons later, in "Jeers for Fears", Chandler and his friends, Trent and Richie, plan on checking out the Royal Woods House of Terror. Chandler believes that Lincoln and Clyde are too chicken to visit the attraction themselves, but when Lincoln says that he and Clyde plan to go there themselves, Chandler opts to tag along. When they eventually do go to the House of Terrors, however, Chandler and his two companions ultimately are the ones who end up running out of the house in fear first, as it turned out that they were too scared by the House of Terrors. Chandler then sees that Lincoln and Clyde successfully made it all the way through the House of Terrors (unaware that the pair were actually just as frightened as he was), and worries that they might rub in his shame at school. But Lincoln and Clyde tell him that they won't do that to him, and as a result, he comes to respect them a lot more.
However, in the next season's "Wheel and Deal", Chandler is back to being in an antagonistic role, this time appearing as one of Lincoln and Lana's rivals in the Royal Woods soapbox derby. He is only keen on winning the race rather than getting to meet Bobbie Fletcher like Lana wants to. Seeing how much better his and the other race-cars are over the one Lana has built leads Lincoln and his friends to try to cheat in Lana's favor during the race.
Outside of the show itself, Chandler also appears in the book Campaign Chaos!, in which he is Clyde's rival in the election for school treasurer, and episode 13 of the Listen Out Loud podcast, in which he snags the table meant for Lincoln and Clyde, and wins a chance to spin the Wheel of Pizza at Gus' Games and Grub.
