Amin and MohammadMehdi were two immortals who had been fighting against each other since the beginning of time. Amin was an Iranian nationalist, and he believed that his homeland should always come first, no matter what. His rival, MohammadMehdi, was an anti-nationalist Iranian who believed that the idea of a state was a man-made concept and that people should live freely without any borders. The two immortals had fought each other in several wars throughout history. They had been on opposite sides of the Battle of Marathon, had fought in the Crusades, and had even been present during the French Revolution. Everywhere they went, they would try to destroy each other, no matter the consequences. One day, in the early 20th century, Amin and MohammadMehdi found themselves in Iran, just before the country's revolution. Amin was on the side of the Shah, wanting to keep Iran as a traditional monarchy, while MohammadMehdi was in favor of democracy and anti-Shah reforms. The two immortals found themselves once again at odds. They would clash violently during protests, and their powers would be unleashed, causing destruction everywhere. But the conflict came to a head when the Shah's forces, with Amin by their side, attacked a peaceful demonstration. MohammadMehdi was among the protesters when he saw what was happening. He tried to use his powers to stop the fighting, but Amin was too powerful. The anti-nationalist Iranian was struck down and seemingly defeated. As the demonstration was crushed, MohammadMehdi lay on the ground, gravely injured. But he was immortal, so he knew he would heal quickly. It was then that he realized that their fighting was pointless, and that they had been enemies for far too long. When MohammadMehdi woke up, he went to talk to Amin. He found him alone, thinking about what had happened. And during their conversation, the two immortals agreed to put an end to their rivalry and to work together towards a better future for Iran. After that day, Amin and MohammadMehdi traveled the world together, working on social, cultural, and political projects that would benefit the Iranian people. They became close friends, and the rivalry that had plagued them for so long was forgotten. Their immortal powers were now used to make the world a better place, and they were celebrated throughout history as two of the greatest heroes to ever walk the earth.
