This idea sounds pretty interesting to me. My idea so far is Castor Swaine, human Martian in an advanced age of humanity. He's a colonial guardsman on the distant planet of Odysseus, where a mysterious force in the alien wilderness has been whispering to him secrets and stories. 

Abilities:
•Combat Training - Trained by his parents in basic self-defense, then trained by the United Colonies to be a colonial guardsmen in general combat expertise (but mostly geared towards defence against alien wildlife, though pirates are not an unknown threat).

Powers: 
•Cybernetic Arm - A military grade cybernetic arm. He opted to have no skin cover it, choosing to instead flaunt its machine qualities. Capable of blocking bullets and crushing bones, not to mention moving with far more precise movements than a regular hand, allowing more accurate shots with a gun. 

•Wired Nerves - His nervous system has also been enhanced, allowing him to react much faster than a normal human, roughly double speed.

??? - After making contact with the voice in the wilds, he's felt strange ever since. He gets migraines and stomachaches a lot, but he also seems almost superhuman. He barely feels pain, his eyesight seems... different, almost as if he is perceiving more shades of color, and his strength seems to have almost doubled, even with his non-cybernetic arm.

That's all I got so far. If you need anything changed, just say so.
