Well, Venom has a pretty bad origin story. Eddie Brock was a journalist who lost his job and reputation because of Spider - Man. He then bonded with an alien symbiote out of revenge. His origin is based on jealousy and a desire for vengeance rather than any positive ideals, which makes it a rather unappealing origin story for a so - called superhero.
One of the worst could be that of the Hulk. Bruce Banner was exposed to gamma radiation during a military experiment gone wrong. It was a simple accident that turned him into a monster. There was no grand heroic choice or noble sacrifice leading to his powers, just a scientific mishap. And he has to constantly struggle with his inner rage and the destruction he causes when he transforms.
I think Thor has a great origin story. He is a god from Asgard, banished to Earth for his arrogance. On Earth, he learns humility and what it means to be a true hero. His origin story is filled with grandeur, with the magnificent Asgardian setting and his family drama. It gives a whole new dimension to the MCU by introducing the world of gods and magic.
Some superhero origin stories are the worst because they rely too much on improbable events. For example, in the case of the Fantastic Four, they were exposed to cosmic rays during a space mission. Cosmic rays are extremely powerful and the chances of them just giving superpowers instead of killing the astronauts are very slim. It seems like a lazy way to create superpowers for the characters.
I'd say Mandarin. In some interpretations, his origin story is a mess. It tries to blend a lot of different elements but doesn't do it well. It ends up being this hodgepodge of ideas that don't really come together to create a coherent and engaging backstory for the character.
I think Wolverine has a great one. He was born with a mutant gene that gives him a rapid healing factor and retractable claws. But his origin is also filled with a lot of mystery and experimentation. He was part of a secret program where his bones were bonded with adamantium, which made him even more indestructible. His origin is a mix of his natural mutant abilities and the dark experiments that were done to him, making it really interesting.
One of the worst could be Spider - Man's origin in some aspects. I mean, getting bitten by a radioactive spider is a bit far - fetched. It's not something that would realistically happen in our world. And then he has to deal with the death of his uncle which is a really sad and tough start for a young kid.
Iron Man's origin is quite motivating too. Tony Stark was a brilliant but self - centered billionaire. After being kidnapped by terrorists and forced to build weapons for them, he instead built a suit of armor to escape. This experience changed him. He realized the harm his weapons were causing and decided to use his intellect and resources to become Iron Man, a superhero dedicated to protecting the world. His origin is about redemption and using one's talents for good.
I think 'The New Jedi Order: Vector Prime' was not great. It was the start of the Yuuzhan Vong invasion arc, and while it had potential, it just didn't quite hit the mark. The new villains were hard to understand and not as engaging as the classic Sith or Imperial foes.
I think 'The Legend of Zelda: The Minish Cap' has a great story. Link has to shrink down to minish size to save Hyrule. The story is full of charm, with interesting characters like Ezlo. It combines classic Zelda elements with a new perspective, and the adventure through the small world of the Minish is both exciting and endearing.
I think Arkham City has a great story. It expands on the world of Arkham by creating a prison - like city within Gotham. The conflict between Batman and the various villains, especially the power struggle with Hugo Strange, is really engaging.
