Rajesh «Raj» Koothrappali
Bernadette Rostenkowski-Wolowitz
Sheldon and Leonard’s neighbor from Apartment 4B — a cheerful girl from Nebraska with dreams of becoming an actress. The complete opposite of Sheldon: emotional, spontaneous, down-to-earth. She became something like an older sister to him — teaching him empathy, social skills, and that the world doesn’t revolve solely around science.

A brilliant physicist with an IQ of 187 — he knows everything about quantum mechanics and nothing about human emotions. Obsessed with trains, comic books, schedules, and his spot on the couch. Hates change and germs.
A genius in science, but a complete novice in feelings — until friends and Amy taught him how to be human.

An astrophysicist from India — a kind romantic and eternal dreamer. For years, he couldn’t talk to women without alcohol (which became his signature joke). Loved comics, sweet treats, and nights with friends. Connected to Sheldon through science and geeky hobbies — though often the target of his sarcasm.

A microbiologist with the voice of an angel and the temper of a drill sergeant. Tiny but fierce — she could put anyone in their place, even Sheldon. Howard’s wife, mother of two, and the one person whose rants could terrify even the toughest geeks.
A neurobiologist and the «female version of Sheldon.» Once as awkward as he was, she became his best friend — and later, his wife. With patience and love, she taught him empathy and what it means to be human.
An engineer from MIT — the only one without a PhD, which gave Sheldon endless teasing material. Loved his flashy shirts, his mom’s cooking, and questionable flirting. Later became an astronaut, Bernadette’s husband, and a father of two. Constantly bickering with Sheldon, yet deep down, a true friend.
