The Aquanaut



This is the new human, The Aquanaut!

He must save the world and stop the alien invasion!


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.

Communication device

Placed on the back of the head interface, it is used inside the Terran Shield base to communicate because our vocal cords are useless underwater.


These are the extra-sensors that an ordinary human doesn’t have, an essential addition in low visibility environments. Their area of effect is about 5-10 m.


Although the aquanaut’s lungs alveoli are modified to process the oxygen from the water, the extra oxygen from the newly implanted gills is needed for a warm blooded creature to have a good stamina underwater.

Catheter tubes exit

These tubes drain blood from the femoral vein and clean it in the CO2-DS (CO2 Draining System), then pump it back into the body. The pain killers and stimulants that help the aquanaut in difficult missions enter through the same circuit.

Hands inter-digital webbing

The inter-digital webbing is a nice addition for quick direction changing when fast swimming and also provides extra power when the aquanaut swims overburdened.

Feet inter-digital webbing

The same inter-digital webbing as the hands have, those on the feet help the aquanaut swim faster inside the base. In missions however, the suit fins provide a better solution.
