Is Thena related to Thanos?

Are you asking if the character named Thena, possibly from a comic book or movie franchise, has any connection to the character Thanos, who is well-known as a villain in the Marvel Cinematic Universe? It's quite possible that the two characters share no direct relation, as they may belong to different storylines or even different companies' intellectual properties. However, given the vast and interconnected nature of superhero narratives, there could potentially be some subtle LINK or Easter egg that connects them. Could you provide more context or clarify your question to help me give a more accurate answer?
