A rocker at heart, Jackie Oaks is rarely seen without her electric guitar strapped to her back, much to the chagrin of her parents and especially her teachers. Though respectful during classes, she can usually be found during lunch strumming on her guitar and learning how to play "The Classics" such as songs from Areosmith, Guns N' Roses, Metallica, and a few others she had learned from her parents. While a few of her friends wonder why she learns to play that "old" musics she shrugs it off and says she just prefers their sounds to most of the bands today.
Like the others, she was a bit overwhelmed at first when she was pulled into the Digital World but she was able to adjust fairly quickly. This was due mostly to the helpful, cheery attitude of her partner Biyomon who was quick to note they had simpler hair styles. Or at least what passed for hair on Biyomon. They also quickly bonded over their love of music and Jackie was more than happy to teach the bird like Digimon the wonders of human music and encouraged her to use her own beautiful voice more often.
