Who are the main characters often involved in Yellow Lantern Batman fanfiction?

In addition to Harry, there could be other important characters such as Sinestro. Sinestro could initially be an antagonist, seeing Harry as an outsider in the Green Lantern world and trying to undermine him. But as the story progresses, their relationship could become more complex. There might also be the Guardians of the Universe who play a role in guiding Harry in his new role as a Green Lantern.

In many cases, Ra's al Ghul, who is often associated with the Demon Head concept, is a central figure. His complex relationship with Batman adds a lot of depth to the fanfiction. Also, characters like Alfred, Batman's loyal butler, may play important roles. He could be the one providing Batman with crucial information or moral support during the encounters with the Demon Head. There may also be other members of the Bat - family, such as Batgirl, who might get involved in the story to help Batman deal with the Demon Head - related threats.

Batman's allies like Robin (whichever version - Dick Grayson, Jason Todd etc.) are often involved. They might have to deal with the fact that their mentor's identity is now public and face new threats because of it. Also, Commissioner Gordon is a main character. His relationship with Batman has always been complex, and this revelation will surely change how they interact.

Batman and the Yellow Lantern could start off as enemies. Batman is all about justice and the Yellow Lantern's power is based on fear, which goes against Batman's principles. So there could be a lot of tense confrontations at first.

One interesting story could be about Batman being tempted by the power of the Yellow Lantern ring. Maybe he struggles with the fear - based power it offers while still trying to uphold his own code in Gotham. For example, he might face off against his rogues gallery in a new way, using the yellow energy but also fighting not to be fully consumed by it.

Sasuke could be another main character in these fanfictions. He might be initially skeptical about the significance of lanterns but later realizes their importance. Additionally, Kakashi could play a role as a mentor figure, guiding Naruto and others in understanding the power or symbolism of the lanterns in the context of the Naruto universe.

Alina is also frequently involved. Her connection to the Darkling in the original work makes her a natural addition in many fanfictions. Their complex relationship can be further explored or even rewritten in different ways in fanfiction.

One idea could be Batman being forced to team up with a Yellow Lantern to stop a common enemy. Maybe a powerful villain from the fringes of the universe is threatening Gotham and the Yellow Lantern has some knowledge or power that Batman needs.

Peridot is a character that could be paired with Yellow Diamond in fanfiction. Since Peridot was once under Yellow Diamond's rule, there can be stories about her loyalty, her possible defection, or how Yellow Diamond views her. There could also be fanfictions that pair Yellow Diamond with other minor Gems from her colonies, exploring the power dynamics and relationships on a more micro level within the Gem society she oversees.

The connection is often complex and depends on the specific comic storyline. Sometimes it's a brief encounter, while in others, it might have a more significant impact on the plot.
