Georgie Cooper Jr.

George Marshall "Georgie" Cooper Jr. is the eldest child of George and Mary Cooper, and the older brother of Sheldon and Missy Cooper by five years. He has been mentioned in the series long before his first appearance in the penultimate episode of Season 11. He was named after his father George Sr., who died before the start of The Big Bang Theory. As a teen, George went to school with his brother in high school, before dropping out. George likes rock music, such as Guns N' Roses and Bon Jovi. His favorite band member in Guns N' Roses is Axl. He dropped out of high school in his senior year to focus on his job as a salesman. George and Sheldon don't get along, and the pilot of Young Sheldon explains that it's because George is tired of always being compared to his brother.
