I want to know the answer to the following question:
The most popular early Marvel heroes were collectively and colloquially known as what?
All the background I'm provided with is that "While no other Timely character would achieve the success of these "big three", some notable heroes—many of which continue to appear in modern-day retcon appearances and flashbacks—include the Whizzer, Miss America, the Destroyer, the original Vision, and the Angel.". Is that enough to answer the question?
