Not really. 'Miss America' is more of a fictional creation with elements that might draw inspiration from real-life scenarios but not directly based on a specific true story.
I'm sorry, without more specific information, it's a bit difficult to tell the full story. But generally, the Miss India America pageant might involve a journey of young Indian - American women competing. They would showcase their talent, grace, and knowledge of both Indian and American cultures. They might have to go through various rounds like the traditional saree round, a talent show, and an interview round.
Sure. In the comics, after Steve Rogers was believed to be lost or incapacitated, characters like Bucky Barnes and Sam Wilson have taken up the mantle of Captain America at different points.
