He works for ETRA, (extra terrestrial research agency) an intergalactic army ship hosting over 2million troops, all for different countries and ranks. They test for habitability and sustainability across the galaxies, for earth is looking to be a lost cause. Bloodshot, to which his real name is unlisted, is one of the lucky few to test out the new Necrom suits. Necrom is a cyan radioactive substance that keeps the suit warm, and delivers hard hitting attacks when used to full potential.
