Leg swelling is a sign of fluid buildup or inflammation of the tissues or joints of the leg. Swelling can occur anywhere along the leg, including the thighs, knees, calves, ankles and feet. Mild swelling is a common occurrence after standing for a long time, especially in warm weather.
Wonder Woman's is One of the Strongest Heroes. Wonder Woman is stronger than Supergirl because her strength derives from the Earth itself for she is a child of Gaea. While Wonder Woman isn't as strong as Superman she could still hold her own against Superman.
I'd say the most well known and iconic (not including popularity) are in order: Superman (he is THE superhero) , Batman, Spider-Man, Robin (he is THE prototype comic book sidekick, the Burt Ward version is the most imitated superhero persona after Superman) and then Wonder Woman.
