Wendy is Stan Marsh's on-and-off girlfriend, and is also the most outspoken of the 4th grade girls. She's not afraid to go against the grain of what's popular or trendy and stands up for her principles and causes, most notably in her stand-off against Photoshop.
Wendy is one of the most intelligent students in Herbert Garrison's class and is one of the two main voices of reason against Eric Cartman, discovering his forgery in the Save our Fragile Earth contest and calling him out on his Breast Cancer jokes. She's not above teaming up with him though (or kissing him) such as at the Flag Debate.
She's best friends with Bebe Stevens and until very recently, was the Class President of South Park Elementary. Also worth noting: she arranged for her substitute teacher (Ms. Ellen) to be shot into the sun by Iraqis and has beat the crap out of Cartman. So yeah, don't f*ck with her...
She and Stan split for a couple years, putting him into a brief depression, before getting back together after they exposed the conspiracy to alter the Cutest Boys' List. She has since taken over leadership of the List Council.

Wendy's had feelings for Stan Marsh since the pilot episode, where the two worked together with Kyle to save his little brother from the Visitors.. even if he gets so nervous around her vomits uncontrollably every time she speaks. Nonetheless, the two formed a relationship - meeting up for Truth or Dare in his clubhouse, planning fake cruises for Valentine's Day and seeing independent movies together at the film festival
They shared their very first kiss in South Park: Bigger, Longer & Uncut after Stan impressed her by leading the La Resistance forces into action, but after a sexually-transmitted disease scare and a period of silence, she broke up with him (in "Raisins"), leaving him heartbroken and depressed. He recovered soon after but remained bitter for a while.
They eventually rekindled their relationship through the adventures in Season 11's "The List" and seem to have had a much closer and more involved relationship, planning picnics together and studying together after-school. Wendy paid Dr. Chinstrap to help Stan with his hoarding problem and remained concerned about him when he became a "cynical asshole". Stan has, in turn, tried not to embarrass her too much at Pioneer Village and listens to her stupid muthafuckin' problems.
They've both shown signs of possessiveness - Wendy doesn't take kindly to Stan's other Facebook friends or interest in sexy substitutes and Stan freaked out when she befriended Gregory of Yardale, an exchange student, when he thought Kyle might be interested in her and when she displayed an interest in Bridon Gueermo.
After breaking up with Stan, Wendy began dating Token Black. However, she later broke up with him and returned to Stan in The List.
Wendy has been shown to have a crush on Bridon, although she claims she would never leave Stan for him.
Wendy has always had an intense rivalry with Eric Cartman. They argue in class on a frequent basis, and he has targeted her for humiliation on more than one occasion. They can also be very competitive, particularly over the "Save Our Fragile Planet" contest as well as the student body presidency. She has in turn become quite adept at dealing with him, whether it's a matter of fact-based debate, an ass-kicking to remember, or just out-smarting him on school access television. Even when he spends much of his time booing her and accusing her of being a liar, she's not afraid to agree with him on the odd event.
However, on the rare occasion when they found themselves on the same side in the Great Flag Debate, they swapped debate tactics, shared some quadruple-stuffed oreos, and developed a bit of an attraction... which lead to an uncomfortable, public kiss at the Debate. Wendy's attraction to him flamed out immediately afterward, the "sexual tension" resolved, and she later voted him last in the List of Cutest Boys... but Cartman may hold a flame for her yet, notably including her in fantasies where she compliments his weight and ability to fight off Jew-Bots. Nonetheless, he is never afraid to tease her for her liberal beliefs and she certainly isn't afraid to throw down when he steps out of line.
