In 'green lantern rwby fanfiction', a plot could involve a character from RWBY being chosen as a Green Lantern. For example, Weiss. Her strict upbringing and sense of justice could make her an interesting Green Lantern. She would have to learn to control the power of the ring while still dealing with the problems in her own world, like the Grimm. And she might use the ring's power in unique ways, combining her glyphs with the constructs created by the ring.
A cool plot could be an OC Green Lantern who has the ability to create constructs that can mimic different elements from their home planet. So, if their planet has a lot of crystal formations, they can create crystal - like constructs that are stronger and sharper than the normal green constructs. This OC could be on a quest to find a lost artifact from their planet that has the power to enhance the Green Lantern rings even further.
One idea could be that the Green Lantern Corps discovers a threat that has its origin in the Marvel Universe, like a powerful artifact from Asgard that is being misused. The Green Lanterns then have to team up with the Avengers to retrieve and safeguard it. Another plot could involve a character like Hal Jordan being accidentally transported to the Marvel Universe and having to work with Spider - Man to find his way back home while also facing a common enemy.
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.
The world - building aspect is quite interesting. Fanfiction often has to find a way to blend the two universes seamlessly. This means creating new rules for how the Green Lantern powers work in Remnant, or how the RWBY characters might be recruited into the Green Lantern Corps. It's exciting to see how the writers expand on the existing RWBY lore and incorporate Green Lantern elements. For instance, they might explain how the Dust in RWBY could be related to the power source of the Green Lantern rings, or how the Grimm could pose a new threat to the Green Lanterns.
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.
A possible plot is that a powerful villain manages to corrupt the Star Sapphire energy source. A Green Lantern discovers this and tries to stop the corruption from spreading. He teams up with a group of Star Sapphires who are also concerned about the situation. Along the way, they learn about the true nature of their powers and how they can work together more effectively to defeat the villain.
One idea could be exploring the backstories of the minor Green Lantern characters. For example, you could write about how a newly recruited Green Lantern copes with the power and the responsibility. Another idea is to create an alternate universe where the Green Lantern Corps has different rules or enemies. Maybe in this universe, they have to team up with their traditional foes to face a greater threat.
Maybe there's a villain in My Hero Academia who discovers a way to tap into the power of the Green Lantern Corps' energy source. This causes chaos as the heroes have to figure out not only how to stop this villain but also how to deal with the new kind of power they've never faced before. They might seek help from the Green Lanterns themselves, leading to an epic cross - universe team - up.
Well, a cool plot could be that the Green Lanterns discover the Naruto universe and they see Naruto as a potential threat because of his powerful jutsu. But as they interact, they realize he has a strong sense of justice. So they offer him a Green Lantern ring. Naruto then has to learn how to use it while also dealing with the enemies in his own world who see his new power as something to be feared or conquered.
Maybe the Green Lanterns discover Naruto's world and are intrigued by the concept of chakra. A Green Lantern could team up with Naruto to stop an enemy that is threatening both universes. The Green Lantern could use their ring's power while Naruto uses his jutsus, and they could learn from each other's combat styles and abilities.
