History
After losing the secrets of the Super Soldier Serum with the death of Dr. Erskine, the United States Army still wanted to produce more like Steve Rogers.[1] Col. Walker Price and Dr. Wilfred Nagel forcibly recruited Jack and 300 other African-American solders to serve as test subjects to recreate the Super Soldier Serum. To keep the operation secret, families were sent letters informing them of the soldiers deaths.[2]

The Black Super Soldiers
Attributes
Powers
After receiving the experimental recreation of the Super Soldier Serum, Jack gained peak human abilities, including:
- Peak Human Strength: Jack's strength was increased to the peak of human potential. While not superhuman, he was as strong as it was possible for a normal human to be and could lift approximately 800 lbs.[2]
- Peak Human Speed: Jack could also run and move at great speeds, capable of reaching up to 30 miles per hour (he has been shown almost outrunning a helicopter).[2]
- Peak Human Stamina: Jack's musculature produced less fatigue toxins during physical activity than most other humans, though not to a superhuman degree. He could physically exert himself at peak capacity for approximately 1 hour before the build up of fatigue toxins in his blood began to impair him.[2]
- Peak Human Durability: While not superhuman, his body was as durable as a normal human's could be. While still subject to all human physical vulnerabilities, he was more resistant to them than most other humans.[2]
- Peak Human Agility: Jack's agility was also increased to a level that, while not superhuman, was superior to that of any Olympic athlete that has ever competed.[2]
- Peak Human Reflexes: Jack's reflexes were increased to similar levels and were superior to that of any Olympic athlete.[2]
- Accelerated Healing: He was capable of healing from massive blood loss and surgery in less than a few days. Jack is also capable of healing from severe punture and slash wounds that are beyond his level of durability.[2]
