When the Fantastic Four were introduced, Marvel was unsure if it was really prepared to transition from doing science fiction and horror comics to doing superhero comics, so the Fantastic Four originally wore just normal clothes. Even in their second issue, the team is decked out in normal outdoor wear. When the series received a tremendous response from the fans, though, Marvel knew that it had a superhero hit on their hands and so with the third issue, so creators and execs decided to give them costumes. However, they wanted to stick with the basic idea that these were not ordinary superheroes. These were sort of explorers more than traditional superheroes, and as a result, Jack Kirby came up with an awesome sort of utilitarian design for their jumpsuits. Famously, the costumes originally had masks but they decided to drop them.
Let’s play a game. Think of one thing about Lady Death other than her looks. Do you know her real name? Do you know her backstory involving witchcraft and her evil father? Statistically, if you're reading this, you probably just know that she has large breasts, hardly any clothes, and each cover has her posing in a suggestive way. The truth is most comic book fans have seen Lady Death, but maybe haven’t read her series. She is one of the prime examples of the excessively sexualized female characters of the ‘90s.
Much of the success of the film's visuals owes to the physical performances of the actors in the suits, but even more of it is thanks to the atmosphere and carefully crafted darkness of the film's entire look. Of course, as more live-action Turtles films debuted, their visual language began to skew ever closer to the hugely popular films, cutting their effectiveness. The Turtles received updated looks in the recent Michael Bay produced reboot to wildly mixed reactions.
