A war vet can be incorporated as a mentor figure. He could teach Spider - Man some combat techniques he learned in the military. For example, hand - to - hand combat moves that are different from what Spider - Man already knows, which would make him more effective in close - quarter battles.
Many war vet stories are centered around the psychological journey. Some vets talk about the fear they had to overcome before every mission. There was the constant worry about not making it back home alive. But they also talk about how the experience changed them. After coming back from war, they might have a different perspective on life, valuing the simple things more. For instance, a vet might say that after seeing the destruction of war, just being able to sit in a peaceful park back home was a luxury they never thought they'd appreciate so much.
One interesting plot could be a war vet who, after coming back from war, finds solace in the adventures of Spider - Man. He starts to see parallels between his own battles and the ones Spider - Man faces in New York. Maybe he even imagines himself having Spider - Man's powers to deal with the PTSD and the challenges of readjusting to civilian life.
In a way, it could be seen as appropriate if the aim is to create a deeper understanding of the connections between different historical events. The fanfiction could potentially show how the aftermath of WW1 led to the conditions that made the Holocaust possible. However, some might argue it's inappropriate because it might seem to trivialize the Holocaust by mixing it with a fictional concept like time - travel and a personified WW1.
There was a vet who, despite being severely injured, managed to keep his unit's morale high. He told jokes and stories during the tough times in the trenches. His positive attitude was a source of strength for the whole unit. He made everyone believe they could make it through the war, no matter how difficult the situation was.
Well, I once heard about a korean war vet. He said that he saw a lot of destruction during the war. Houses were ruined and civilians were displaced. He was in a unit that was tasked with helping the local population. They distributed food and medical supplies. It was a tough job because of the constant threat of enemy attacks, but they managed to do some good.
One great war vet Spiderman time travel fanfic is 'Spiderman: Through the Wars of Time'. It has an amazing plot where Peter Parker, as a war vet, gets sent back in time during a battle. The author does a great job of showing how his combat skills and Spiderman abilities interact in different historical settings.
One common theme is redemption. The war vet Spiderman may have done things in war that he regrets, and time travel gives him a chance to fix things or make amends. Another theme is the clash of values. Different eras have different values, and as he travels through time, he has to reconcile his modern - day values with those of the past.
There's a fanfiction called 'Young Spidey in Civil War'. It's really good because it explores Spiderman as a young and inexperienced hero in the complex situation of the Civil War. It shows his growth and how he tries to navigate the difficult political and moral landscape of the war between the Avengers.
There's also 'Warriors in Peace'. This fanfiction delves into the different paths the war vets take. Some of them choose to work in the Ministry to prevent future dark wizards, while others retreat from the wizarding world altogether. It's really interesting to see how the characters develop in a post - war setting.
