Already a part of the circle of friends in the pilot episode "Take this Job and Squeeze It", Wyatt is introduced in 6teen as a slightly insecure but compassionate character. He is a talented musician and singer who writes his own songs and who has apparently been playing the guitar since the fourth grade, as was revealed in "Idol Time at the Mall". He is also a former member of his school's audio-visual club.
Wyatt once presented a song about his friends to a talent search competition, Star Contest, and was on the verge of being accepted into the Petty Crime record label. However, as the version of the piece his audience was more impressed with was one that badmouthed his companions (which resulted in them being hated by everyone in the mall), he decided to back down on his dreams to save his friends' integrity, but acknowledged the possibility that he would one day be "the next Alanis Morissette".
While working in the country music section at the music store Spin This, Wyatt was involved in a relationship with his employer Serena after being set up by Nikki Wong. She eventually broke up with him to pursue another of her employees, Chad, and this caused Wyatt to become hostile towards her and her new boyfriend. Despite this fact, he still harbored feelings for her, and set up a "shrine" in his bedroom to honor her.
Finally moving on from his previous girlfriend Serena, in "Snow Job" Wyatt discovers there is life after breaking up when he meets Marlowe. The relatively calm redhead had recently joined Wyatt's band and from there, the two began dating. However, due to spending so much time together, the two found they were getting on each others' nerves more than ever and thus ended the relationship. Marlowe tells him she does not want to just "be friends", telling Wyatt they will be the best of exes. Then she kisses him.
Wyatt is employed in the Galleria Shopping Mall at the Burger McFlipster's fast-food restaurant, where he composes and sings original lyrics to customers, attracting many girls. He previously worked at Underground Videos alongside Jude Lizowski and Jonesy Garcia, but was fired for spilling coffee onto the proprietor's favorite tape, as well as Spin This - where he signed his name on the celebrity wall - and was fired for embarrassing Serena in front of the clientèle. At the beginning of the series, Wyatt had intended to get a job at the Grind Me coffee house, but was refused due to a bad interview. Wyatt is known for his trademark maroon sweater, green cargo pants, blue Converse, and his brown hair is styled in short dreadlocks. He was the only black person in the series
