The conflict between good and evil is a key element. Leonardo represents the good, and Tigerclaw is clearly on the side of evil. Their clashes, both physical and ideological, can create a lot of tension and excitement. For instance, their different fighting styles - Leonardo's ninjutsu training with Splinter versus Tigerclaw's more brute - force and underhanded tactics. Another element is the mystery around Tigerclaw. There could be parts of his past that are slowly revealed in the fanfiction, which could add depth to the story.
One idea could be a story where Leonardo and Tigerclaw are forced to team up temporarily to defeat a common enemy greater than their rivalry. Maybe a new, powerful mutant emerges that threatens both the turtles and Shredder's plans. This would put them in a situation where they have to rely on each other's skills.
Leonardo would be a likely candidate. He is often the most level - headed of the turtles and believes in honor and justice. He might see the potential for a greater good if he can end the hostilities with Tigerclaw, so he could be the one to make the first move towards a truce.
One possible storyline could be a battle of wits between Leonardo and Tigerclaw. Leonardo, being the leader of the Turtles, would constantly try to outsmart Tigerclaw. For example, he could set up elaborate traps to catch Tigerclaw and stop his evil plans. Tigerclaw, on the other hand, would be constantly trying to anticipate Leonardo's moves and turn them against him. Another storyline could be a more complex relationship where they start to understand each other's motives over time. Maybe there could be a situation where they have to team up against a common, even greater enemy. This could lead to a begrudging respect between them.
One interesting plot could be their unlikely alliance. Maybe in a story, they are forced to work together to face a common enemy that threatens the whole clan. This could lead to a lot of tension as they have to put aside their differences.
Maybe in the fanfiction, there is a prophecy that involves Tigerclaw and Leo. They are initially skeptical but as strange events start to unfold around them, they are forced to work together. Along the way, they face many challenges like distrust from their own sides, but their growing friendship helps them overcome all that.
The family dynamic is a key element. Charlie being Bella's father creates a unique relationship. For example, his protectiveness towards her. Also, the setting of Forks can add an interesting backdrop. It's a small town with its own secrets and that can play into their relationship.
One interesting storyline could be them going on a joint adventure to solve a mystery that threatens their world. They might combine their unique skills, Donatello's intelligence and Leonardo's leadership, to outwit the villains.
One key element could be how the Saiyan traits are incorporated into Naruto. For example, his enhanced strength and fighting abilities. Also, the relationship between Naruto and Kushina could be explored in a new light, perhaps with some unique backstories or interactions based on the Saiyan concept. Another aspect could be how the Naruto universe is changed or affected by these Saiyan elements.
Maybe in a different universe where their clans have a more peaceful co - existence. Leonardo and Karai meet during a cultural exchange of sorts between the turtles and the Foot Clan. As they learn about each other's cultures and values, they grow closer.
Well, it's interesting because it takes two beloved characters from the Teenage Mutant Ninja Turtles franchise and explores a different kind of connection. In the original series, their relationship is mainly platonic. But in fanfiction, writers can play with different scenarios. They can put them in situations where they have to rely on each other more, and that can lead to a deeper emotional bond that we don't usually see in the official storylines. Also, the different interpretations of how their relationship could develop add to the allure. Some might write it as a slow - burn romance, while others might have them realize their feelings more suddenly.
