Georgie Cooper is Sheldon and Missy's older brother and he resents the attention his parents especially his mother pay to Sheldon. He does not do well at school and gets mocked and teased for it but he himself is a football player who is very impulsive and bullies his little brother.

Sheldon Cooper is the youngest of the siblings and a child prodigy with a very high iq which is almost 200. His twin, Missy, is in middle school but Sheldon skipped it and attends high school with his brother who is embarrassed of him.

Missy is the middle child, she is a social butterfly but she is very sassy. She isn't afraid to speak her words and her mother is fed up with her mouthing off, although when her father witnesses it, he merely smirks in praise of her.

Mary Cooper is a pious lady who works in the church and loves Sheldon the most. It would be a lie to say she treats her children fairly because it's pretty obvious she prefers Sheldon the most although she denies it.

George Cooper is the dad and works as a football coach at the high school the boys attend, he is fair with his children. His children respect him, especially his daughters and Georgie because he treats them equally.

The youngest daughter is a mix between all of the siblings, she's social but not too social and she's not the favourite child either. Missy and Georgie already claimed her as their favourite siblings as soon as she was born and although Sheldon claims he doesn't believe in foolish things like 'favourites', he definitely prefers her.
