Not always. While the MCU draws inspiration from the comics, there are often changes and adaptations made to fit the cinematic universe and modern audiences.
In certain comic arcs, the Falcon was indeed subjected to freezing. This was often part of elaborate plot developments and challenges he had to overcome.
Falcon was a science fiction novel with the global space as the background. It mainly told the story of a young female astronaut who encountered an accident during her mission and lost her precious husband and daughter. However, she did not give up. Instead, she chose to face everything firmly and led a young team to start her new space mission. In the process of completing the mission, she encountered various difficulties and challenges, but she never gave up and finally successfully completed the mission and became a real hero.
Captain America's origin story is quite interesting. Steve Rogers was a weak but very brave and kind - hearted man. He was selected for an experiment to create a super - soldier during World War II. The experiment transformed him into the strong and patriotic Captain America. His origin is deeply rooted in the war - time context and the need for a symbol of hope.
There's a good chance they will. Comic Con is a major platform for promoting and generating buzz for upcoming MCU films and shows. But it depends on their schedule and promotional plans.
