I got all the Slade particulars from the Teen Titans figure and glued them onto a Micro Man body, with a Storm Shadow head instead of the original as it was too small and cartoony to work here, imho.
After Captain America's revival from the ice, the Government also revived the Super Soldier program. A Marine veteran of Desert Storm, Slade Wilson volunteered for the regimen.
During the Joe team's hiatus, Snake Eyes was brought in to teach the candidates martial arts. Although it was a watered-down version of Arashikage ninja techniques, Wilson showed a natural grace and efficiency of movement that made him a deadly combatant with even just "Arashikage-lite" schooling.
After surviving this version of the Super Soldier serum, Slade immediately became intoxicated with his new abilities and set out on his own to make some bank as the assassin known as DeathStroke the Terminator. Accepting assassination contracts based more on his political sentiments of who's a bad guy in the world, it doesn't seem to faze DeathStroke that many of his hits leave a country vulnerable to takeover by COBRA.
