Many comic book characters will enter the public domain in the coming decades. Batman, Superman, and Wonder Woman will enter the public domain in the mid and late 2030s. Superman would enter the public domain on Jan. 1, 2034. Batman on Jan. 1, 2035. Wonder Woman on Jan. 1, 2037. However, you don’t necessarily have to wait for that. Some of the best public domain heroes and analogues at Marvel and DC exist.
Thor, Ares, and Dracula are public domain characters. Hawkeye and Green Arrow are analogues of Robin Hood, a public domain character. There is one character on this list that is paradoxically public domain and technically still not public domain, and you should not use it.
