Epilogue:
After the defeat of Thanos and the battle with the alien invaders, Tony found himself torn between two worlds. He had grown to love his life on the surface and the friends he had made as an Avenger, but he also felt a strong pull towards his responsibilities as the prince of Atlantis.
One day, Tony received a message from his father, Poseidon. He was being summoned back to Atlantis for an important meeting with the council of elders.
Tony knew that this was his chance to make a decision about his future. He met with the Avengers and told them that he needed to leave for Atlantis, at least for a little while.
"We understand," Steve said, placing a hand on Tony's shoulder. "You have a duty to your people."
Tony nodded, feeling grateful for their understanding.
When he arrived in Atlantis, Tony was greeted with open arms. The council of elders explained that there had been a rise in threats to Atlantis and they needed their prince to take charge and lead them to safety.
Tony accepted the responsibility, feeling a renewed sense of purpose. He worked tirelessly to protect his people and his home, using his powers to defend against any threat that came their way.
Months went by, and Tony found himself feeling more at home in Atlantis than he ever had before. But he couldn't forget about his life on the surface, the friends he had made, and the world he had sworn to protect.
One day, a familiar face appeared in Atlantis. It was Thor, who had come to visit his friend and bring him some news from the surface.
"The Avengers need you, Tony," Thor said, looking at him seriously. "There's a new threat that's emerged, and we need your help to stop it."
Tony knew what he had to do. He said goodbye to his family in Atlantis and made his way back to the surface, ready to reunite with his friends and fight for the world he had grown to love.
As he arrived back on the surface, Tony felt a sense of belonging that he had never felt before. He was a prince of Atlantis, but he was also an Avenger, a protector of the world.
Together with his friends, Tony faced new challenges and threats, but he never forgot the lessons he had learned in Atlantis. He knew that he had a responsibility to protect both worlds, and he was determined to do just that.
And so, Tony Stark, the prince of Atlantis, continued to fight for the safety of all, using his powers to defend against any threat that came his way, and always ready to answer the call of his duty, no matter where it may take him.
