Supersoldier

A supersoldier is a fictional soldier that operates beyond normal human limits or abilities. Supersoldiers are common in science fiction literature, films, TV programs, computer, conspiracy theories, and video games, but have also made appearances in other related genres, such as military fiction and spy fiction. Many depictions of supersoldiers treat them as shock troops or heavy infantry, although others feature them as elite commandos or special forces personnel.

Supersoldiers are usually heavily augmented, either through eugenics (especially selective breeding), genetic engineering, cybernetic implants, drugs, brainwashing, traumatic events, an extreme training regimen (usually with high casualty rates, and often starting from birth or a young age), or other scientific and pseudoscientific means. Occasionally, some instances also use paranormal methods, such as black magic or technology and science of extraterrestrial origin. The creators of such programs are viewed often as mad scientists or stern military men, depending on the emphasis, as their programs will typically go past ethical boundaries in the pursuit of science or military might.
