Nika was a Human who was hired under Judge for work at BlackStar, and after her first mission she asked for a medical
examination.
Finding some irritation with a previous medical issue involving a hip fracture, she submitted voluntarily to the drone program to remove the pain (and fracture, as well as infusing nano-rubber with the rest of the bones and body).
They now work in HR, or "HDR" to include Drones as well, both acting as resources to the gal.
Their form can change depending on how much nanotex is in the suit, with a maximum of 15 ft long.
They can also store items inside their tail and belly.
They're not very effective at stealth missions.
