Sarah
Sarah is Ed's bossy, psychotic, spoiled, abusive brat of a little sister, who acts cute and charming only when it serves her. Sarah has Ed's unending loyalty and obedience, mostly due to her constant threats of tattling on him. The fact that their mother always believes Sarah, even when she is fibbing, doesn't help. She has a very loud mouth, a hair-trigger temper, and is easily agitated by others, especially her brother. She is almost always hanging out with Nazz or playing with Jimmy, and when she's not, she rushes to his aid the moment he calls her. Sarah writes about her innermost feelings in her diary, and has a crush on Edd (though this is usually not quite enough to spare him from her wrath). It's been shown that she shares her brother's superhuman strength, as demonstrated when she dropped a car on Nazz in "Truth or Ed". In "Little Ed Blue", she was apparently surprised to learn that her brother is much stronger than her, and is even more dangerous than she is when in a bad mood. Several minutes into the episode, she shouts at him, only to have him shout right back at her even more loudly and with more menace, which frightens her and makes her back off. She also seems to fear the Kankers, because unlike her brother, the sisters aren't afraid to bully the younger girl to get what they want. Eddy has yet to learn not to mess with Sarah, and it is often he who provokes her into physically attacking the Eds.
