And no, we don’t know why she has a swastika necklace either. But it might have been some certain weasels.(It’s in the wrong direction to be the nazi one anyway)
The Story of Blue on /tg/
A very shitty thread was posted on /tg/, about a cultural exchange with the T'au where they send a T'au Girl over in exchange for- Oh fuck it, who cares, it was a terrible opening. Cue a lot of generic fetish comments, and that sort of thing.
One poster wondered what would happen if the Orks were the ones to be a part of this exchange, and things spiraled out from there. People posted little stories of how they thought it might go, and a name was coined - Blue. The idea gained traction as the thread went on, and eventually ended up with a vaguely fleshed out character, one with drawings as well. The rest of the threads can be found here, though you'll need to scroll down a bit.
The story of Blue in the Universe
During Warboss Urtylug's raid of a T'au colony, the T'au were falling back and at one point abandoning a small colony on a satellite world. Orks of the Scraplootas clan were raiding the colony, looking for a cloak befitting a Warboss (he was looking to loot the Ethereal's) and taking advantage of a chance to show off their Titan, Boris.
Raised an orphan and accidentally abandoned by her caretakers during the mayhem, a young T'au girl was left alone in her habitation block. The Orks didn't even notice her, looking for a proper fight, but some Snotlings and Gretchin eager to steal her hiding place decided to gang up on her.
She then proceeded to pick up her T'au spanner and kick, punch and wallop her way into a corner, fighting off all the Snotlings and Gretchin in her way. Just at the right time, Big Mek Tinka Zizzbitz came to kick all the Snotlings upside the head for forcing him to do his own heavy lifting, indirectly saving the young T'au girl. Mistaking her for a blue Grot, and noticing she already had a wrench, he picked her up and told her to get back to work.
Thanks to her Earth Caste upbringing she had a rudimentary knowledge of machines and mechanics, and her ability to help the Mekboys inventions work made her a utility to the Orks (although really Zizzbitz just thought that she was a lucky charm due to her blueness and enjoyed her willingness to do his work for him).
Now the Ork Big Mek keeps her close and acts to protect her (at least telling other Orks to shove off), while she herself has an added ability to kick some of the smaller Orks/Grots upside the head if they do cause her trouble.
Her ability to add dakka and her understanding of T'au technology is also a boon to the Orks and "Da Blue Grot" has become somewhat of an endearing name for her.
She has a pet of sorts, a Squig who flies around in a small Drone. Showing off her very Orky imagination, she named him "Mr Squig". He buzzes around her, bumping into things often, hungrily chasing Grots, and being a general nuisance.
Also of note is the T'au spanner she has kept since she was picked up by the Orks. It is a sentimental memento regarding her unknown parents as much as it is a personal lucky charm, which she believes is more effective than any others she has used. Regardless of whether it is or isn't, it holds value to her. She is seldom seen without it.
She builds better than Grots, she's smarter than Grots, T'au warriors think twice about shooting at any Trukk she's riding and she's blue so she's lucky. The Scraplootas really picked a good 'un.
