First, know the characters well. For Pythor, study his motives and personality from the original series. For the OC, develop a detailed backstory. This helps in creating a believable relationship between them.
One idea could be creating an OC who is a long - lost relative of one of the main ninjas. For example, a cousin of Kai who has been living in a far - off land and has a unique fire - based power that's different from Kai's. Another idea is an OC that is a hybrid of two different elemental powers, like water and earth, and they struggle to fit in with the normal elemental groups. Or an OC who is a master of an ancient and forgotten form of Ninjago martial arts that the ninja team discovers and tries to learn from.
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.
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. There are some really cool action scenes and the dialogue between the two characters is well - written, which makes it a great read for beginners in this type of fanfiction.
One great 'Ninjago Cole x Reader Fanfiction' is 'Cole's Heart'. It really delves into the relationship between Cole and the reader in a very sweet way. The writer does an excellent job of portraying Cole's character as we know it from the show, while also creating a unique bond with the reader character.
One great 'Ninjago Jay x Zane Fanfiction' is 'Electric and Ice'. It beautifully explores their friendship evolving into something more. The author does a wonderful job of portraying Jay's energetic nature against Zane's calm demeanor, and how they complement each other. It has some really sweet moments that make you root for their relationship.
Lemon fanfiction often contains inappropriate and non - canon content. However, in the context of Ninjago Kai x Reader, it might explore a more romantic or close relationship between Kai and the reader. But such fanfictions may deviate from the original family - friendly and action - oriented nature of the Ninjago series.
I don't think it's very popular in the mainstream Ninjago fandom. Since the Ninjago series is family - friendly, most fans are more interested in the official storylines, the battles, and the development of the ninja characters. Lemon fanfiction often contains adult - like content which goes against the general tone of the series.
One great 'Ninjago Cole x Jay fanfiction' is 'Bond of Brothers'. It beautifully explores their friendship and how it could potentially turn into something more. The author does an amazing job of capturing their personalities and the dynamic between them within the Ninjago universe.
One popular theme is the 'opposites attract' concept. Since Jay and Cole have different personalities and skills, this makes for an interesting dynamic. For example, a fanfiction might focus on how their differences initially cause friction but then lead to a deeper understanding and attraction.
