In the era of civilization, the global situation had become increasingly stable, and there was hardly any need for large war machines.
Under normal circumstances, the research on large weapons was mainly to deter enemies and not for aggression.

Heroic combat form referred to using individual advantages to achieve the same effect as large war machines.
The research was divided into two fractions.

The first one would be Captain America who represented the pursuit of human potential and the exploration of the human body's upper limit. This was the culmination of genetic engineering.
