This P.I.X.A.L Lineage Nindroid has a fascinating history, one that completely deviates from the other 15,
Cyrus was lonely when he was building the being that would become Chloe, he only wished for a friend, a companion when he brought her online in front of a crowd of over 300 people, but he immediately abused her by suppressing her emotions at the same time using the Emotion Suppressor Chip, he even he admits later on that this was wrong of him.
(Chloe when she came online in 2001)
Despite him constantly suppressing emotions of hers that he did not like a relationship formed, a romantic relationship this is where she greatly deviates from her 'sisters' she was not built to be a daughter of Cyrus but a companion a friend of Cyrus and at one point in time she was even his fiance.

Cyrus and Chloe both were the typical nuclear relationship and she had even branched out and gotten her teaching degree but just a couple months after their engagement Chloe would go offline.
There was nothing that Cyrus could do to bring her back online he had already tried with Violet to fix them and bring them back online but anytime he attempted to do that the memory banks would start erasing themselves, he was forced to store them away.
For close to two decades Chloe would lie in storage with the others, until season 3 when Zane showed Cyrus how to align the memories of a Nindroid with a body.
By the time she was brought back online too much time had passed they both agreed that they'd start anew, she took up residence as just another daughter of Cyrus their memories would be put away in a box along with their engagement rings and other memories for several years Chloe worked as head of security of Borg Industries trying to find herself
The problem being is that Chloe was frequently picked on and Cyrus would ignore any Android phobic slurs that were thrown her way again he would admit this was a fault of his because he could never really see Chloe as a daughter after all they had been through but he should have been there to defend her as her boss and friend.
Chloe would leave Borg Industries due to these actions moving in with Simone a fellow Pixal the 10th she would find her niche in the hacking world her experience as being head of security gave her knowledge on all the weaknesses of Borg industry technology.
Nowadays, she's known as The Chameleon due to being able to constantly throw the law off her due to a Cloaking device and has hooked up with a new partner Mr E of the Former Sons of Garmadon aka Echo Julian, both connecting over shared history of not really knowing themselves or being able to fit in.
They have no qualms on targets it's for the thrill of it, even Simone became one of these targets nearly being offlined permanently by the other
(Chloe, after attacking Simone she crushed the others' powersource)
She even trusted him to reroot her hair, which leads to her current natural look under whatever Cloaking she has on
