One interesting fanfiction could be about Lloyd and Garmadon teaming up against an even greater evil than they've ever faced. Maybe a new dark force emerges that threatens to destroy all of Ninjago, and they have to put aside their differences and work together. Lloyd uses his newfound powers and Garmadon uses his knowledge of the dark arts in a way that benefits the good side for once.
Misako is usually developed as a strong - willed and intelligent character. In fanfic, her knowledge of ancient Ninjago lore might be explored more deeply. Her character might grow as she tries to understand Garmadon's fall to darkness and her part in it. Garmadon, on the other hand, can be developed by showing how his past experiences, like his upbringing and his encounters with the dark forces, shape his actions. His relationship with Misako can also be a catalyst for his character development, as he might strive to be better for her.
One way is through different scenarios. Suppose Garmadon is possessed by an even greater evil force. Lloyd has to find a way to save his father not just from the external threat but also from the internal darkness. This would show the lengths Lloyd is willing to go to for his father and how Garmadon responds to his son's efforts, highlighting the complexity of their bond.
One interesting plot idea could be a pre - series story exploring how Misako and Garmadon first met and fell in love. Maybe it was during their training days at the monastery. Another could be a story where Garmadon has been redeemed and he and Misako are trying to rebuild their relationship while also dealing with the reactions of the other ninja. Or perhaps a story set in an alternate universe where Misako and Garmadon are on a quest together to save Ninjago from a new, unknown threat.
A healer - type oc would be an interesting partner for Garmadon. This oc could be trying to heal Garmadon's physical and emotional wounds. Nya could also be a good pairing. She is intelligent and strong - willed. In a fanfiction, she could be the one who challenges Garmadon's ideas and helps him see things from a different perspective.
Ninjago might be interested in Ninjago fanfiction because it could offer new ideas for their own battles and challenges. The fanfiction world is full of creative minds, and there could be some brilliant strategies or concepts in those stories that they could adapt. Also, it could be a form of entertainment for them, just like how we enjoy fictional stories about other things.
If Ninjago watches Ninjago fanfiction, they could get a whole new perspective on their own world. Some fanfictions might show them in different relationships or situations that they hadn't considered before. It could also inspire them to do things differently in their own adventures. For example, if a fanfiction has a really clever solution to a problem they've faced, they might think about using a similar approach in their own world.
Another fanfiction could be set in an alternate universe where Garmadon and Misako never had their fateful split. They could be living a peaceful life, raising Lloyd together, and using their combined skills to protect Ninjago from other threats that are not related to Garmadon's own dark side.
Well, there could be a garmadon oc fanfiction that focuses on a time - travel scenario. An oc goes back in time and tries to prevent Garmadon from making certain bad decisions. This would involve a lot of action and also some deep emotional moments as the oc tries to convince Garmadon. There might also be a fanfiction where an oc is a student of Garmadon during his brief stints as a teacher, and they go on adventures together.
