Appearance[]
- This section is incomplete.
Personality[]
A free spirit like many Anodites, especially her grandmother, Chelsey is a lover of older music. In addition, she is extremely lax, whether it be in relationships or with the tenuous line between legal and otherwise. She constantly considers how what she's doing affects her family - without the money, they'd have been on the streets for a decade now.
History[]
Background[]
Since she was five years old, she has known her great aunt Verdona, having been introduced through her Anodite parents.
She grew up in Colorado, out of sight of the other Tennysons. There, when she was 8 years old, she met her to-be best friend Charmcaster, who for a long time she only knew by "Hope." As Plumbers, Chelsey's parents did not (and to this day, do not) make too much, making it difficult to financially support the family. As such, through the years where one, two, three, and now four sisters have joined her, Chelsey schemed alongside Charmcaster for valuable treasures or cash to help pay the bills.
Her family eventually moved to Bellwood to rekindle ties with the other Tennysons, and simultaneously, she met Ben, who extended a helping hand.
Back in Action: Alien Universe[]
- This section is incomplete.
- In Magikfest, she fights alongside Charmcaster and soon meets the rest of her family.
- In Can't Trust the Weather, Man, a date with her new boyrfiend is cut short so she can charge in to defend Bellwood from Hurricane Vance.
- In Plight of Pinocchio, hanging out with Ben (which was also supposed to include an absent Mercedes) is truncated by a call from Kevin about Charmcaster trying to kill Gwen. When she goes to end the fighting, they end up in an elongated battle with Eunice where Chelsey and Charmcaster's bickering causes them to reveal their true feelings for each other but also somewhat part ways.
- In Malevolence, she joined Gwen, Kevin, and Mercedes to help Ben push back against Vilgax and Malevolence in their quest to break out of Null Void Incarcecon.
