For character development, 'Kailor: Trials and Triumphs' is excellent. It shows Kai and Skylor facing different challenges that force them to grow. Kai becomes more understanding and less impulsive, while Skylor learns to be more open about her feelings. It's a great read if you want to see the characters evolve.
Another one is 'Kailor: Unleashing the True Self'. Here, the story takes the characters on a journey of self - discovery. Kai discovers new aspects of his power, and Skylor learns to embrace her true identity. Their relationship blossoms as they become more confident in themselves.
There's also 'Kailor's Adventure in the Spirit Realm'. In this one, Kai and Skylor get transported to the Spirit Realm. It's full of mystery and danger. They have to rely on each other to survive and find their way back. The way the author describes the Spirit Realm is really vivid and makes the whole story very engaging.

One idea could be that the OC is a new villain who teams up with Pythor. They could have a common goal like taking over Ninjago City. The OC might have unique powers that complement Pythor's skills.
I would recommend 'Zane's Promise'. In this fanfiction, the relationship between Zane and the reader is very well - developed. It shows Zane's loyalty and how he would do anything to protect the reader. It's full of sweet moments and also some action scenes that are really exciting.
Zane would also be a good choice. Zane's logical thinking could contrast with Aspheera's more emotional and power - hungry nature. Maybe he could try to reason with her and understand her motives better than the others.
I'd recommend 'The Adventure with Lloyd'. It's simple yet exciting. It quickly sets up the scenario where the reader gets involved with Lloyd.
