After several painful surgeries and implants of new organs made from stem cells, the aquanaut was ready to be the humanity main weapon and hope. At the beginning, the operation success was very low, around 15% -20%. So all the volunteers could be considered true heroes, because for the few to succeed and became aquanauts, many of them remained crippled for the rest of their life, or dead.
The aquanauts have had gills implanted and their lungs have been modified with a special film that can collect the oxygen from the water and deliver it to the alveoli.
In addition, their eyes were modified with a supplementary reflective area in their back, so that they can see 3 times better in low light environments than a normal human.
Their back muscle were improved to sustain the “dolphin” style of swimming, that is the fastest and the lower energy consumer underwater swimming style, adapted to human anatomy.
Extra skin was implanted between the fingers of their hands and feet, for more underwater mobility.
On the skin of their forehead, the medics implanted several electric-receptors connected to the aquanaut’s brain that can detect the surrounding living organisms’ electric signature. An essential addition in muddy and opaque waters, where their sight would be useless.
On the back of their heads a special brain interface was implanted. This connected to a powerful computer and to a flexible column that linked all the components of the battle backpack.
The gel battle backpack and the special gel diving suits function as armor as well, and are used only during missions. In their underwater base the aquanauts can swim freely in an oxygen rich water that has 36 oC and is constantly purified.
