Kekkou
Contents
Background
Not too long ago the scientist Dr. Drool created a new pet, to play with and learn his idea of social behaviour. In his lab he grew the little bioroid to his pleasing. As he is as brilliant in biology and genetics as he is crazy, the result was in his eyes more or less "perfect".
Perfect in this case is maybe an ill-chosen term, but Dr. Drool was quite satisfied with his creation. His goal was to make a sturdy and reliable design that still could pass more or less unnoticed in most situations. Over the three year lifespan, Kekkou has gone through over a dozen enhancements to the first concept. Not much has changed that can be seen externally but quite a few differences are hidden internally.
Body
Kekkou is more or less a humanoid bioroid with plenty of features taken from rabbits and other rabbit-like species. She is close to six feet long (almost as long as many human males) but is quite lean. Those two factors makes her look quite fragile in some circumstances. That is far from the truth, as she is quite muscular and extremely agile.
Muscles and skeleton
That brings up one of the enhancements: Her muscles are slightly stronger, per muscle fibre, than a normal human, but they don't use as much energy to function at high stress. They also have more reserves before getting tired and beginning to ache.
One thing that Kekkou was built for is high G movement and combat. Her muscles are very tear-resistant and almost all her tendons are close to ten times as strong as a normal human. Dr. Drool is very keen on keeping that fact a intellectual secret, as it is a very lucrative bio-material he ended up with mostly by accident. Adding a soft and stress-enhanced (tension) skin makes maneuvers in extreme Gs and high impact forces possible, as her muscles flow and bend around the bones and the skin keeps most things in place.
Her bones are slightly stronger but much harder than most mammals, and they are perfectly smooth. All to add to the damage-resistance during high G situations.
