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.
They contribute in several ways. Firstly, they keep the fans engaged between movie releases. They also introduce new concepts and ideas that might later be incorporated into the movies. For instance, some new villains or plot twists can first be tested in the graphic novels. Also, they can provide different interpretations of the characters, adding more dimensions to the overall MCU franchise. Moreover, they can attract new fans who are more into reading graphic novels rather than just watching movies.
The origin stories give depth to the characters. Captain America's origin, with his roots in World War II, adds a historical and moral weight to the MCU. His values shape his actions and influence other characters. Also, his origin story allows for interesting time - travel and alternate - reality plotlines later in the MCU.
A great MCU fanfic is 'Tony Stark's Secret Legacy'. This fanfic delves deep into the backstory of Tony Stark, exploring things that the movies might not have had time to touch on. It gives more depth to his character and his relationships with other MCU characters, like Pepper Potts and Rhodey. It also has some really cool tech concepts that are in line with the MCU's love for high - tech gadgets.
