Dark Horse Comics is a significant player in the comic industry. They publish comics in different styles and themes, and have made a name for themselves with some really cool and unique offerings.
A dark horse comic is typically a comic that comes out of nowhere and gains a significant following. It might not have been expected to do well based on initial expectations or the publisher's marketing efforts. Sometimes it's because of unique storytelling or innovative art.
I wouldn't say Dark Horse Comics is bad. They have a diverse catalog with some really unique and interesting stories. But of course, not everything they put out will be a hit with every reader.
A 'dark horse story' could be about an underdog who unexpectedly achieves great success. For example, in a horse race, a dark horse is a horse that is not expected to win but does. In a broader sense, it might be a story of a person who rises from obscurity to stardom against all odds.
You can start by visiting the official website of Dark Horse Comics. They often have digital versions available for purchase and reading. Some libraries might also have physical copies you can borrow.
Dark Horse Comics and Marvel are distinct entities. Marvel has its own roster of characters and storylines, and Dark Horse has developed its own unique properties and franchises over the years. So, they have no ownership connection.
