Young Sheldonhas been a huge and surprising hit for CBS. A spin-off of the hugely successful sitcomThe Big Bang Theory,Young Sheldonfocuses on the titular character’s infancy, growing up in Texas with a deeply conservative but loving and supporting family struggling to live with a child genius.

The show revolves around Sheldon but has a great cast of supporting characters, many of which are more likable than the young savant. Indeed,Young Sheldon’s initial hook was the main character, but his family and friends have endeared themselves to critics and audiences, making the show a fan-favorite juggernaut.

10Pastor Jeff

Jeff Difford is the local pastor at the Coopers' Baptist Church. Upbeat but still stubborn, Pastor Jeff is a strange character in the show. He clashes with Sheldon over several religious issues; however, to his credit, he is far more capable of keeping up with Sheldon’s idiosyncrasies than most other characters.

Still, Pastor Jeff is an adversarial figure in Young Sheldon. The young protagonist considers him an enemy because of his affiliation with the church; moreover, Pastor Jeff often meddles in others' business, making him an entertaining but somewhat annoying character in the show.

9Billy Sparks

Sheldon mentions Billy Sparks several times inThe Big Bang Theory, describing his neighbor as a bully who once shoved a Mexican Peso up his nose. However,Young Sheldondisproves this, showing Billy as a dim-witted and clueless young boy who, at best, irritates rather than bullies Sheldon.

However, Billy is far from one oftelevision’s most annoying characters. In fact, he can be quite likable due to his unassuming, happy-go-lucky attitude. Billy is harmless and harbors a long-standing crush on Sheldon’s sister, Missy, leading many fans to believe he will grow up to become her first husband.

Mandy gives birth to their child, Cece, and eventually, she begins dating and becomes engaged to Georgie despite their 11-year difference.

Mary’s close-minded attitude often makes her slightly exasperating. However, she remains a loving and committed mother, supporting her children through every situation. Mary is not the show’s most likable figure orone of television’s most iconic mothers, but she is a compelling character who always does what she thinks is best for her family.

Sheldon Cooper is one oftelevision’s most iconic know-it-alls.Jim Parsonsoriginated the character inThe Big Bang Theory, receiving critical acclaim and earning four Emmy Awards for his portrayal, whileIain Armitageplays the character’s child version inYoung Sheldon.

Like his grown-up version, young Sheldon is arrogant, selfish, awkward, and lacking a basic understanding of social dynamics. However, he is also surprisingly thoughtful and sporadically empathetic, proving there’s more to him than just cold-hearted intelligence. Armitage does a remarkable job capturing Parson’s mannerisms without outright imitating him; instead, the young actor makes Sheldon his own while maintaining the character’s essence.

4George Sr.

George Sr. is another character that Sheldon misinterpreted inThe Big Bang Theory. Sheldon describes his father as a violent alcoholic who shared a chaotic and abusive relationship with his mother. However,Young Sheldonportrays him as a laid-back and highly understanding man trying to do what’s best for his family while coming to terms with his own failed dreams.

Lance Barberplays George Sr. with a unique mix of empathy and level-headedness that makes him the audience’s surrogate in the show. George is arguably the show’s most relatable character, a man doing his best to support his family while dealing with his children’s shenanigans.

Georgie is also deeply ambitious, showing a talent for sales and negotiation from an early age.Young Sheldonshows him beginning several successful businesses, hinting at his future success in life as the owner of a tire company. Georgie is surprisingly thoughtful and caring, making him one ofYoung Sheldon’s most unexpectedly likable characters.

First introduced in season 2 ofThe Big Bang Theory, Missy is Sheldon’s twin. Unlike her brother, she is more spirited, determined, resourceful, and witty. Missy might lack Sheldon’s brains, but she makes up for it in street smarts and instinct, much like Penny.
