That is indeed.
Interesting (?): The rules of copyright are that a corporation has ownership of a character (or rather that specific version of) for 95 years from first publish etc. But if it’s owned by a person solely it extends for the life of the creator plus 70 years.
Cardiac was co-created by David Michelinie and Erik Larson in 1991 so the copyright ends in 2086. But if Erik Larsen lives say another another 20 years (he’s 63 now) the Savage Dragon copyright will remain with his family/trust until 2116. Savage Dragon 1 was published in 1993.
I dunno, this is just kind of interesting to me.
