In "The Loudest Thanksgiving", it is revealed that Lincoln is vulnerable to tryptophan which causes him to fall asleep before Thanksgiving dessert is served. For the first four seasons, Lincoln attends Royal Woods Elementary School with his younger sisters Lucy, Lana, Lola, and Lisa and is a 5th grader there. Lincoln often breaks the fourth wall by talking to the audience about living with all of his sisters and considers himself the "man with a plan." He tries to give helpful advice concerning sibling relationships.

Lincoln wears an orange polo shirt, blue jeans, gray socks, and white sneakers. Lincoln has other talents, including cooking, playing video games, performing magic tricks, and coaching his younger sister Lola to prepare her for her pageants.

He is also, however, the primary leader of his ten sisters, as he typically plans schemes, strategies, and "operations" for better convenience, as well as to help others, that the girls more often than not follow. Alongside his little sister Lisa, Lincoln is the family nerd. Lincoln has a passion for comic books, especially his favorite superhero Ace Savvy who has a playing card theme as well as secret agent David Steele. The character got his name from E Lincoln Avenue in Royal Oak where the show's creator Chris Savino grew up.
