One possible fanfic could be about a trainer in the Pokemon Sky world who has a special encounter with Giratina, Darkrai, and Gengar. Maybe they all meet in a mysterious forest. The cake could be a magical item that restores their energy or is a key to a hidden place. For example, the trainer uses the cake to lure Gengar out of a spooky cave, and then Giratina and Darkrai show up because they sense the power of the cake.
Perhaps the story could revolve around a quest for the cake. Giratina, being a powerful and otherworldly Pokemon, might think the cake has some sort of dark or mysterious power. Darkrai, with its ability to manipulate dreams, could be lured by the idea that the cake holds the key to a perfect dream world. Gengar, always up for some fun and trouble, tags along. They might face various challenges in Pokemon Sky, like battles with other Pokemon or traversing difficult terrains all in the pursuit of this cake.
Gengar is a Pokémon. It was once a Haunter. In the Pokémon lore, it is said that Gengar was born from the shadow of a person. It lurks in the darkness and often plays tricks on people. It has a mischievous nature and uses its ghostly abilities to startle or confuse its victims.
There was a forest known for its strange happenings. A group of hikers decided to explore it. As night fell, they set up camp. One of the hikers saw a strange shadow that looked like Gengar. They thought it was just their imagination at first. But then, Gengar started to make eerie noises. It began to play tricks on them, moving their supplies around. The hikers were terrified and quickly tried to leave the forest, but Gengar followed them, disappearing and reappearing to keep them on edge.
Well, perhaps Gengar's sad story involves it being shunned by other Pokémon in its original form. It might have been a misunderstood Pokémon that was always thought to be evil. So, it had to endure the loneliness of not having any friends. It was constantly chased away and had to hide in the shadows, which led to its transformation into Gengar, a more menacing form, but still with a sad heart.
One key element is its evolution from Gastly and Haunter. Another is its connection to shadows and darkness. Also, its mischievous nature is important.
The main elements in the Gengar sad story could include isolation. It may have been isolated from its kind or other Pokémon, which made it feel sad. Also, betrayal could be a factor. If it trusted someone or something and was betrayed, that would cause great sadness. Additionally, the loss of a home or a safe place might be in the story. Without a place to belong, Gengar's sadness grew and shaped it into what it is now.
One common theme is friendship. Ash and Gengar form a strong bond in many fanfictions, like in stories where they help each other through tough battles or difficult situations.
The unique feature is the combination of different elements. For instance, when Gengar crosses with a character from a different game or story, it brings new powers and abilities into play.
In this kind of fanfiction, it would be a really interesting twist. Ash usually starts with Pikachu, but having Gengar as a starter would change a lot of the story dynamics. Gengar is a Ghost/Poison type, which is much different from Pikachu's Electric type. This could lead to different battle strategies and interactions with other trainers. For example, Gengar's ability to phase through walls and its spooky nature could add a whole new element to Ash's journey. Maybe he would face more challenges against trainers who are used to dealing with the typical starter Pokémon types like Fire, Water, and Grass.
