Well, if we assume it's non - adult related and just a unique take on Yoshi and Peach. It might have the characteristic of combining their different personalities. Yoshi is usually seen as friendly and helpful, while Peach is more of a damsel - in - distress but also has her own strength. In such fanfiction, they could be shown having adventures that play on these traits.
One possible characteristic could be the exploration of their relationship in a new light. If it's not about adult content, it could be about how Yoshi and Peach interact on a deeper level. For example, Yoshi could be Peach's protector in a different way than Mario usually is. Or they could have some sort of magical connection that is explored in the fanfiction, with Yoshi's unique abilities and Peach's princess - like powers coming together to solve problems in the Mushroom Kingdom.
Since Yoshi is a dinosaur - like creature and Peach is a princess. In 'yoshi and peach lemon fanfiction' (assuming it's a creative and appropriate take), there could be a characteristic of mixing different worlds or aesthetics. Yoshi's more natural, wild - like world with Peach's refined and regal world of the Mushroom Kingdom. Maybe the stories would show how they bridge these two different aspects and learn from each other.
It's a bit difficult to directly recommend 'yoshi and peach lemon fanfiction' as the term 'lemon' in fanfiction often has adult - related connotations which are not appropriate. But if we just consider Yoshi and Peach in regular fanfiction, you could start by looking at the works of some popular Mario fanfiction authors. They might have created stories that feature Yoshi and Peach in unique and interesting scenarios, like a story where they team up to save the kingdom from a new threat.
Often, these fanfictions might emphasize the contrast between Yoshi's gentle nature and Birdo's more flamboyant personality. Their love could be depicted as a sort of 'opposites attract' situation.
One common theme could be the contrast between the sweet nature of peaches and the tartness of lemons. This contrast can be used to create interesting character dynamics, like a story where a sweet - natured 'peach' character and a more sharp - tongued 'lemon' character become friends or fall in love.
One key element is the interaction between Naruto and Peach Lemon. Since they are from different fictional concepts, seeing how they communicate and understand each other is important. For example, Naruto's energetic nature might contrast with Peach Lemon's more calm or mysterious side.
One common theme could be friendship. Luigi and Peach might be portrayed as good friends who support each other through various challenges in the Mushroom Kingdom. Another theme could be adventure, where they team up to face a new threat or explore a new area.
The unique feature is the crossover of two different universes. Sonic, from his high - speed action world, and Peach Lemon, perhaps from a more magical or different setting, coming together creates a new and exciting dynamic.
I'm not entirely sure as there could be different interpretations. But generally, Black Yoshi might have its own unique role in the Yoshi's Story world. Maybe it has special abilities or a particular journey within the game's story that sets it apart from other Yoshis.
One possible plotline could be Luigi and Peach going on a secret adventure together that involves solving a mystery related to the 'Lemon' element, perhaps a magical lemon that has special powers. Another could be a love story where Luigi has to overcome some obstacles to be with Peach, and the 'Lemon' part could be some sort of inside joke or unique aspect of their relationship in the story.
One reason could be that Yoshi is lonely. Maybe his friends are off on their own adventures and he's left alone in the game world. It makes him sad.
His color makes him special. It's not a common color for Yoshis, so he's easily distinguishable.
