The Marvel universe has birthed some of the strongest characters brought to life in comics over the past century, but one gamma-radiated, green-skinned phenomenon who's always on hand to prove his might over all comers is the Incredible Hulk.
Bruce Banner's alter ego has appeared in numerous guises and versions. We've known Hulks of different skin tone, Hulks with varying power levels and with different measures of intellect, but one thing always remains true: He is The Strongest One There Is.
Since debuting in 1962, the jade giant has been forced into situations where incalculable strength is required, and he's more often than not been the man for the job. Although others have wielded Hulk-like powers over time, none have shown the same propensity for mind-bending displays of power like the original ball of stress, Dr. Banner.
It's important to underline the difference between "strength" and "power." Power might speak of a being like The Living Tribunal, capable of altering space and time, while strength refers to the more physical concept of moving, lifting or perhaps punching things or objects. That's where Hulk shines.
