The rest of the team would be a mix of shocked and excited. Superboy might be a bit skeptical at first, thinking it could be some kind of trick. But once he realizes it's really Wally, he'd be glad to have another teammate back. Aqualad would probably be more diplomatic, welcoming Wally back but also being cautious about how his return will affect the team.
Miss Martian would be very emotional. She's a very empathetic character. She'd sense Wally's emotions and would try to make him feel welcome. And Batman, well, he'd be observing closely. He'd want to make sure that Wally's return doesn't bring any unforeseen problems to the team or the overall mission. He'd also be interested in finding out where Wally has been all this time.
Wally could be developed by showing his growth in character. For example, if he was a bit cocky before, he could return more humble and with a deeper understanding of the world. This change could be a result of his experiences while he was away.
The team is devastated. Artemis might go into a deep state of grief and blame herself for not being there to protect him. Robin could become more withdrawn and focused on finding out who or what caused Wally's death. Superboy might struggle with anger, feeling like he should have been stronger to prevent it.
Well, in certain fanfictions, his death could be a result of a villain's elaborate plan. The villain might have found a way to disrupt the speed force that powers Wally. They could have created a device that nullifies his powers temporarily, and then, while he was vulnerable, dealt a fatal blow. This would be a tragic turn of events, especially for his friends in Young Justice who rely on him.
Some members of Young Justice could be embarrassed. For instance, if there are romantic fanfictions about them that are a bit too cheesy or if their weaknesses are overly emphasized in a not - so - flattering way. But others might be really intrigued and want to explore more of what the fans think about them.
One great 'Great Wally West Young Justice' fanfiction is 'Speedster's Redemption'. It delves deep into Wally's character, exploring his growth after facing some tough challenges in the Young Justice universe. The author does a wonderful job of capturing his voice and the relationships he has with the other characters.
One great fanfiction could be about Wally West getting some unexpected training from Doctor Fate. Maybe Fate sees potential in Wally's speed and decides to teach him some magic - related skills to enhance his combat abilities. This could lead to some really cool adventures where Wally has to combine his super - speed with new magical powers.
In many fanfictions, Wally and Superboy make for an interesting pair. Superboy's strength and Wally's speed can lead to some really cool action - packed scenes. Also, Megan, with her telepathic abilities, paired with Wally can bring out some unique storylines. For example, she could use her powers to help Wally in a different way during a mission or understand his inner thoughts better.
The emotional impact would be far - reaching. For the Young Justice team, it would be like losing a part of their family. There would be a lot of guilt, not just from Artemis but from others who might think they could have helped. His death could also lead to a change in the team dynamics. They might become more cautious, or some members could become more reckless in their attempts to avenge him. It would be a very difficult time for everyone involved in the Young Justice universe in the fanfiction.
Well, it could be that Wally returns with new superpowers. Maybe he was in some sort of time - warp or alternate dimension and comes back stronger. He might have to prove himself to the team again that he's still the same Wally they knew.
Some of them might be amused. They could laugh at the creative and sometimes silly ideas in the fanfictions.
