Green Lantern might also be involved in team - building aspects in the fanfiction. His leadership skills from the Corps could be applied to help the Young Justice group become more cohesive.
In Young Justice fanfiction, the Green Lantern often serves as a powerful and inspiring figure. His power ring gives him a unique set of abilities that can be explored in various ways. For example, his ability to create constructs allows for creative combat scenarios and problem - solving in the fan - made stories.
Hal Jordan could be the main character. He could be in a mentoring role for the Young Justice members, sharing his experiences as a Green Lantern. His cocky and confident personality would add an interesting dynamic to the story as he tries to teach the younger heroes.
One great Green Lantern fanfic in the Young Justice OC realm could be those that explore an original character's journey in the Green Lantern Corps. For example, some fanfics focus on how an OC deals with the power of the ring and the responsibilities that come with it. They might show the OC training with other well - known Green Lanterns like Hal Jordan or John Stewart.
Perhaps a story where a Green Lantern ring chooses an unexpected candidate in the Young Justice universe. This person might not have the typical 'hero' qualities at first. They then have to prove themselves not only to the Green Lantern Corps but also to the Young Justice team while dealing with the newfound power and responsibility.
You can start by looking on fanfiction.net. It has a large collection of Young Justice fanfics, and there are likely many that feature an OC as a Green Lantern. Just use the search function and type in relevant keywords like 'Young Justice', 'OC', and 'Green Lantern' to narrow down the results.
One idea could be an OC Green Lantern from a different planet arriving on Earth and having to adjust to the Young Justice team's way of doing things. They might have unique powers related to their home planet's culture that add new elements to the team's battles.
One plot idea could be the sidekick having to step up when the Green Lantern is incapacitated. They might have to face a new and powerful villain alone, using their own wits and the limited Green Lantern powers they've learned. For example, they could use the power ring to create constructs in creative ways to outsmart the enemy.
Hal Jordan's sidekick could be a young pilot in training. Since Hal is also a pilot, this sidekick would share that passion. They could be someone who idolizes Hal and is constantly trying to prove themselves. In a fanfiction, they could face challenges related to living up to Hal's reputation while also carving out their own identity as a hero.
Start with their backstory. Consider where they are from in the universe. If they're from a war - torn planet, it could shape their views on peace and justice. For example, they might be more aggressive in their use of the Green Lantern power compared to others.
