Character: Steve Rogers (AU)
Powers/abilities: Equivalent to canon!Steve (minus some modern world training). His enhancements from the serum make are supposed to make him at peak human capabilities. He's able to budge at least one ton or more of debris under duress and lifted a motorcycle with three women sitting on it over his head. His bones and muscles are more dense than the average human, the former are difficult to break. He's been able to jump from great heights, break through reinforced glass and land on both solid surfaces and the ocean without injury. His stamina and speed are enhanced, reflexes are also enhanced and he has a gymnast (or ballerina)-like control over his own body. He doesn't tire easily and heals at least four times faster than a normal human. His memory and mental processes are also enhanced - though he's no genius-level intellect, it's part of what helps him learn quickly.
Any nasty side-effects or drawbacks: The metabolism thing, I figure it makes it more difficult to put him under with or use painkillers.
