Maybe she's trying to get their attention. In a world full of mutants like in TMNT, it can be hard to be noticed. The girl might think that this rather bold action of pulling on their ears will make the mutants focus on her. It could be that she has a message for them or wants to ask for their help, but doesn't know any other way to approach them.
Perhaps she's just being mischievous. In many fan - made stories, there are characters who engage in playful yet odd behaviors. She might see it as a fun way to interact with the mutants without really thinking about how they might feel.
Well, one possibility is that the mutants get really angry. After all, having your ears pulled is not a pleasant experience. They might chase the girl, leading to a wild chase scene through the sewers or the city streets. This could then lead to the girl realizing she's in over her head and trying to make amends with the mutants.
They might be shocked at first. It's not every day that someone pulls on their ears, so it could take them by surprise.
One idea could be creating an OC (original character) who has a unique power related to nature, like being able to control plants. They could join the New Mutants and have to learn to control their power while also dealing with the group dynamics. Another idea is an OC with teleportation abilities but has a fear of getting lost in the teleportation process. They would have to overcome this fear while helping the New Mutants on their missions.
His sense of justice. Power Rangers are all about doing what's right, and saving a life in danger is a top priority for them.
One interesting storyline could be the OC's encounter with the TMNT in the jungle and how they team up to face a common enemy. Maybe there's a new mutant or a group of bad guys causing trouble in the jungle.
Another theme could be the power of art. The deaf dancer uses dance as a form of expression, which is really powerful. It might also be about breaking barriers. Despite being deaf, the dancer doesn't let that stop her from being part of the TMNT's world and doing what she loves.
There's also the 'mentor - mentee' trope. If the OC is a highly skilled ballerina, she could become a mentor to the turtles in terms of grace and balance, which they can apply to their fighting. In return, the turtles can teach the OC self - defense and how to be brave in the face of danger, which is something she may lack in the ballet world.
Well, 'oc' usually stands for 'original character'. So it might mean that an original character in a Teenage Mutant Ninja Turtles (TMNT) fanfiction is taking care of something or someone. Maybe it's about an original character looking after the TMNT or other characters in the fan - made story.
A popular one is the fanfiction where the male OC is a lost ninja from another dimension. He teams up with the TMNT and together they learn new fighting techniques from each other. The author does a great job of describing the battles and the cultural exchange between the different ninja backgrounds.
