The Ironman Triathlon originated from a debate among some athletes in Hawaii in the 1970s. They were arguing about which athletes were more fit - swimmers, bikers or runners. So they decided to combine the three disciplines into one event. That's how the Ironman Triathlon was born.
One great Ironman story is about John MacLean. He was a paraplegic athlete who completed an Ironman. His determination against all odds was truly inspiring. He trained hard and overcame physical limitations to cross that finish line. It shows that the Ironman is not just about physical strength but also mental fortitude.
Well, for starters, 'Iron Man: Armor Wars' is a definite must-read. It has intense action and showcases Tony Stark's ingenuity. Also, 'Iron Man: Director of S.H.I.E.L.D.' offers a fresh take on the character in a new role. And don't forget 'Iron Man: Legacy', which delves deep into his past and motivations.
One common theme is the clash of their different personalities. Batman is dark and brooding, while Iron Man is more flamboyant. Their interactions often explore how they deal with this contrast.
A prevalent theme is adaptation. Ironman has to adapt to the new rules and environments of the crossed - over universe. For instance, in a crossover with a historical - based world, he has to work within the limitations of that era's technology while still using his own skills. Also, identity exploration can be a theme. How does Ironman maintain his identity as a hero in a completely different world? This is often explored in these fanfics.
