Sheldon is a rather tall, skinny, adorable 9 year old kid. He is about 4'5" (1.35 m). while he is a kid, his fashion is more adult-like.

Sheldon is in his room, playing with a realistic toy train.

Sheldon was born alongside his twin sister Missy Cooper on February 26, 1980, in a Kmart in Galveston, Texas to the late George Cooper Sr. and Mary Cooper and was officiated at the Lawrence Memorial Hospital. He has an older brother named George Cooper Jr. Sheldon was raised according to his mother's Evangelical Christian doctrines, (i.e., learning how to pray and becoming the co-captain of the East Texan Christian Youth Holy Roller Bowling League Championship team and seven-to-twelve year-old division). Meanwhile, he was forced to watch football by his father. Like any typical nerd, Sheldon was bullied a lot during his childhood, mostly because he constantly expressed intellectual superiority to his peers as he still does now. The bullying consisted of, but was not limited to, being beaten up, getting wedgies, being stuffed in small spaces, and having his personal belongings stolen.

“I've always loved trains. In fact, if my career in theoretical physics hadn't worked out, my backup plan was to become a professional ticket taker. And when I figured out that trains allowed me to prove Newton's first law... An object in motion stays in motion with the same speed and in the same direction, unless acted upon by an unbalanced force... I felt like Neil Armstrong on the moon, alone and happy.”

Sheldon thinked to himself.

“I don't care how dimwitted you are. Scientific principles have to make you smile. Of course, nobody I knew in East Texas in 1989 cared about Newtonian physics. The only Newtons they cared about were Wayne and Fig.”

Sheldon smiles to himself.
