One key difference is their origin. Hercules is from Greek mythology, a demigod born from a god and a mortal. Wonder Woman is from the fictional island of Themyscira. Also, their powers are different. Hercules is mainly known for his extreme physical strength. Wonder Woman has super strength too, but also has powers like flight, and the ability to use her Lasso of Truth.
Supergirl has super strength which allows her to lift extremely heavy objects. She also has heat vision that can be used as a weapon. And of course, she can fly. Wonder Woman, on the other hand, has super strength as well, but she has unique weapons like the Lasso of Truth which can force people to tell the truth, and her indestructible bracelets which can deflect bullets.
The Wonder Woman comic has a long history. It debuted in 1941 and has continued to evolve and captivate readers over the decades. So, it's been around for more than eight decades.
