Amy Farrah Fowler didn't appear in The Big Bang Theory until the very last episode of season 3, yet she's a character who feels like she was there since the beginning.
After only meeting Sheldon because of a dating agreement she had with her mother, it seemed pretty clear that she was the perfect match for the theoretical physicist.
Before meeting Sheldon and the rest of the gang, Amy never really had any other friends. In high school the closest person she had to a friend was the janitor. Yet, by the end of the show she had a tight group of friends and a bestie in Penny.
In fact, Sheldon entering her life changed not just her friendships but their work together resulted in her winning a Nobel Prize in Physics.
