Well, the story in 'Superman: Birthright' is quite good. It has a fresh take on the Superman - Metallo dynamic. The art in it also enhances the whole experience of their encounter.
The 'Superman: Red Son' story has an interesting take on Superman vs Metallo. In this alternate universe story, the political and ideological differences between Superman and Metallo are brought to the forefront. Their battles are not just physical but also a clash of their different worldviews. It's a thought - provoking and engaging story that stands out among the Superman vs Metallo tales.
One of the great ones is 'Action Comics #489 - 491'. In these issues, Superman faces off against Metallo in a really intense battle. The story shows Metallo's kryptonite - powered strength as a major threat to Superman.
One of the best is 'The Dark Knight Returns'. In this story, an older Batman comes out of retirement and clashes with Superman who is sort of a government enforcer. It shows their ideological differences and the grittiness of the Dark Knight against the more 'establishment' Superman.
One of the best is 'Final Crisis'. In this story, Darkseid's plan to reshape reality is opposed by Superman. It shows Superman's unwavering will against Darkseid's tyranny. Another great one is 'Superman: The Darkseid War'. It features an epic battle between them with high - stakes and amazing power displays.
I think the 'Man of Steel' origin story in modern comics is one of the best. It delved deeper into Krypton's society and politics before its destruction. This added more context to Superman's story and made his journey to Earth more meaningful. Also, his growth and development as a hero in this origin are well - presented.
Many fans consider the Golden Age comic origin to be the best. It was the first and set the foundation for all future interpretations. It introduced the world to Superman's origin on Krypton and his powers on Earth. This origin story is simple yet powerful, and it has influenced every other version that came after it.
Character development. In the best stories, both Batman and Superman grow. For example, in 'The Dark Knight Returns', Batman has to face his own mortality and Superman has to deal with his loyalty to the government. This makes their conflict more than just a physical fight.
Iron Man would probably win. He has a highly advanced suit with a plethora of weapons and defensive systems. His suit is constantly evolving and he has the genius of Tony Stark behind it. Metallo, while strong with his kryptonite - powered body, Iron Man could analyze his weaknesses and use his repulsors, missiles and other gadgets to take him down.
One interesting plot could be where Metallo somehow gets an upgrade that can disrupt Iron Man's technology. Then Iron Man has to rely on his wits and basic engineering skills to fight back. Another could be a scenario where Iron Man has to protect a city from Metallo without using his full - powered suit, making it a more challenging fight.
One of the great ones is 'The Dark Knight Returns'. It shows an older, more grizzled Batman coming into conflict with Superman. The art style is very unique and it really delves into the ideological differences between the two.
The story where Superman is faced with the choice of saving the world or saving Lois Lane. His decision to try and do both, because he values both humanity and his love for Lois, is a great representation of his values.
