Powers

Marlow possessed various superhuman attributes as a result of ingesting a derivative of the Super-Soldier Serum that was used to create Captain America.

Superhuman Strength: The SSS derivative augmented Marlow's musculature, granting him a slight degree of superhuman strength. At his peak, Marlow possessed sufficient strength to lift approximately 1,000 lbs.

Peak Human Speed: The SSS derivative also increased Marlow's running speed to the peak of human efficiency. Marlow could sprint at speeds of up to 30 miles per hour.

Superhuman Stamina: Marlow's augmented and superior musculature produced less fatigue toxins during physical activity than the musculature of a normal human. At his peak, he could exert himself at peak capacity for up to 3 hours before the build up of fatigue toxins in his blood began to impair him.

Superhuman Durability: Marlow's bodily tissues were augmented by the SSS derivative to the point that they were tougher and more resistant to some kinds of injury than the bodily tissues of an ordinary human. While far from invulnerable, Marlow could withstand powerful impact forces. He could withstand impacts, such as being struck by a superhumanly strong opponent or falling from several stories, that would severely injure or kill a normal human with little to no injury to himself.

Superhuman Agility: The SSS derivative augmented Marlow's natural agility, balance, and bodily coordination to levels that are beyond the natural physical limits of the finest human athlete. Marlow's agility was often likened with that of a tiger.

Superhuman Reflexes: Marlow's reflexes were similarly enhanced and were superior to those of the finest human athlete.
