Well, Naruto's chakra-based powers and Pikachu's electric powers can combine in some fanfictions. For instance, Naruto could use his Rasengan and Pikachu could add its electric charge to it, creating a super - charged attack that is more powerful than either of their individual attacks.
One common reason could be jealousy among other Pokemon. Some Pokemon might be jealous of Pikachu's closeness to Ash and its popularity. So, they might plot against it and end up killing it. Another reason could be a misunderstanding. For instance, a wild Pokemon might misinterpret Pikachu's actions as a threat and attack it fatally.
There was a Pikachu who lived near a beautiful forest stream. One day, it met a Pikachu from a far - off place. They immediately felt a connection. They started to explore the forest together, looking for shiny stones and new places to nap. Their love grew as they shared these adventures, and they became inseparable, always by each other's side.
I'm not sure if there is a specific 'ash no pikachu fanfic' out there. There are countless fanfics in the Pokémon fandom, but this particular one might be hard to find. You could try searching on dedicated fanfic websites like FanFiction.net or Archive of Our Own and use the relevant keywords to see if it exists.
Detective Pikachu is not a visual novel. It's a unique form of entertainment that combines live-action elements with Pok茅mon characters in a cinematic adventure. Unlike a visual novel, it focuses on visual and narrative experiences on the big screen.
Pikachu's Pokémon friends could also be main characters. For example, Pikachu's best friend, a Squirtle, could be there to offer moral support. It could bring little gifts like small shiny stones to cheer Pikachu up during the pregnancy and be there when the baby is born.
Perhaps Pikachu is lured away by something more appealing. There could be a rare and powerful Pokémon or a special kind of food that distracts Pikachu from protecting Ash. Also, Pikachu might have received some false information. For example, it might have been tricked into thinking that Ash has a better chance of escaping the Spearow without it. In the heat of the moment, Pikachu makes a hasty decision based on this wrong information.
One way to develop her character is through her relationships. Besides Ash, she could have a special friendship with other Pokémon in Ash's team. Maybe she is like a big sister to the younger Pokémon, teaching them things and protecting them. This would show her nurturing side and develop her character further.
