It is an experimental GAARD program for the creation of enhanced soldiers more powerful than average
The Super-Soldier Serum is a formula to create super soldiers. But the name is a misnomer, as the Super Soldier creation actually consists of various processes. Subjects that are considered to have been enhanced to their “Peak-Potential” are noted to be Sarge Hawk, Riff, Thick, Scorch, Shrap and Hoover. Variations of the Super-Soldier Serum have been developed over the years which induced greater-mutations that peak human capabilities, but also created monsters by mistake.
So far, it would appear that Sergeant Hawk is the “perfect Army Man”. But some variants come with strange side-effects that may also include mental & behavior deficiencies, like the rest of the Bravo Company Commandos: Thick, Shrap, Hoover, Scorch and even Riff in a less grade.
Some time later the Tan Army created their own Super Soldier clones, copies of Sgt. Hawk and the rest of the Bravo Company Commandos, with exception of Hoover.
Sarge Hawk & Co. were the first Super Soldiers, considered “SS1” (Super Soldiers 1). A few years later, Super Soldiers 2 (SS2) could begin to be produced. These were still upgraded common soldiers, but also began to be produced from scratch. Although inferior than SS1.
Some time after the production of SS2 started, the SS1 Super Soldier molds stolen by Lord Malice were made available to “the highest bidder” and most armies paid the plastic necessary to obtain their own Bravo Commandos, since these were still superior to the SS2.
Years later, with the rest of the armies in the great alliance, everyone shared their particular research on the subject and managed to create multiple and more varied types of Super Soldiers. After SS4 and SS5 they practically lost count of Super Soldier numbered versions, being an irrelevant and unnecessary system of classification, because of the different and diverse ramifications that left the standard system.
