In a 'Young Justice Outsiders Wally Returns' fanfiction, he might return as a changed person. He could have lost his memories while away and slowly regain them as he interacts with his old friends. His return could also bring back old threats that were thought to be gone. For example, an enemy from his past might resurface, believing that Wally holds the key to something they want.
Definitely Superboy. His complex origin story and his relationships with other characters like Miss Martian are always interesting to explore. Also, Beast Boy is quite popular as he brings a lot of humor and his own set of powers and emotional baggage.
A great plot for Young Justice Outsiders fanfiction could involve a crossover with another DC team or universe. Maybe the Outsiders accidentally end up in an alternate dimension where they have to team up with unlikely allies to get back home. This would introduce new dynamics and challenges for the characters.
It could be a new villain who has a vendetta against speedsters. Since Wally is a speedster, this villain might see his return as an opportunity to prove himself. Maybe he's a scientist who has developed a weapon specifically designed to counter speedsters' abilities.
One idea could be an OC with a unique power, like the ability to manipulate sound waves. They could join the Outsiders and use their power in unexpected ways during battles, for example, creating sonic illusions to confuse enemies. Another plot could involve an OC who is from a different dimension and has to adapt to the Young Justice Outsiders' world while also bringing some of their own world's knowledge and technology. Or perhaps an OC who has a personal vendetta against a villain that the Outsiders are also after, and they initially clash with the team but then learn to work together.
One idea could be that the Outsiders are called in to help the Young Justice team when a new, powerful and mysterious villain emerges. This villain has a unique power that neither team has faced before, forcing them to combine their skills and resources.
To create a memorable OC, start with their power or skill. If it's something that no one else in the Young Justice universe has, like the ability to communicate with animals in a very special way, it immediately makes them stand out. Then, think about their relationships. Do they have a love - hate relationship with one of the existing characters? How do they interact with the different personalities in the Outsiders? Their motivation is also key. Are they in it for revenge, justice, or something else? All these elements combined will make your OC memorable.
Definitely Superboy from Young Justice and Black Lightning from the Outsiders. Superboy has his super - strength and Kryptonian - like abilities, while Black Lightning has his electrical powers. Their different personalities, with Superboy being more brash and Black Lightning more experienced and level - headed, could lead to some great character - development moments and interesting interactions.
Well, it could be really interesting. They might be amused by some of the creative interpretations in the fanfiction. Some might find it strange to see their own characters in different scenarios that the fans have come up with.
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.
