who was the first marvel superhero created by stan lee

The first Marvel superhero created by Stan Lee was the Destroyer , co- created with artist Jack Binder and debuting in Mystic Comics #6 in 1941.
Quick Scoop
- Stan Lee’s first original superhero creation was the Destroyer (Keen Marlow) , a masked World War II-era vigilante fighting Nazis, published by Timely Comics (the company that would become Marvel).
- This predates his later, more famous co-creations like the Fantastic Four (1961), Spider-Man, Hulk, Thor, and others, which came in the 1960s Marvel Age of Comics.
- The Destroyer never reached the cultural impact of those later heroes and is now a relatively obscure Golden Age character, often rediscovered when fans ask who was the first Marvel superhero created by Stan Lee.
So if the question is “who was the first Marvel superhero created by Stan Lee,” the spotlight goes not to Spider-Man or the Fantastic Four, but to the Destroyer in 1941.
