*FAIR USE/COPYRIGHT DISCLAIMER: Though these names/characters have been popularized by Marvel Comics and the MCU, they are NOT copyrighted by Marvel.
Both “fair use” law in the United States and copyright “renewal” laws protect writers from any parties seeking “copyright infringement” claims involving the “illegal use” of characters that have A. not been copyrighted by the original creator/author, or B. an expired copyright.
