The popularity of 'legendary twilight fanfiction' lies in the fact that fans are already in love with the Twilight world. They want more stories set in that universe. It allows them to explore different scenarios and relationships that the original might not have covered.
There's also 'The Legendary Twilight Encore' which focuses on the backstories of some of the minor characters in Twilight. It gives them more depth and significance, making the Twilight universe feel even more rich and detailed.
Well, in this case, a fanfiction being 'legendary' might mean that it gives Ash a very special role. Maybe he's the chosen one to unlock some hidden power of the legendary Pokémon. It could also be about the settings. If it's set in a long - lost, mythical land full of secrets and ancient powers related to the legendaries, that would contribute to it being a 'legendary' fanfiction. The plot could involve Ash facing challenges that are on a scale never seen before, like battles against multiple legendary Pokémon at once or trying to prevent a cataclysmic event that only he can stop because of his connection to the legendaries.
The Snakes, especially those related to Orochimaru's summons, are often used in fanfiction. They can bring an element of mystery and danger. Some fanfictions might explore the idea of a redeemed snake summon that helps Naruto in his quests, or a more powerful, ancient snake that was hidden away until now.
Articuno, Zapdos, and Moltres are quite common. Their elemental powers and the mystery surrounding them make for great fanfiction material. Ash might encounter them during his travels and have to either help them or face off against them in some way.
One of the Legendary Pokemon could be Giratina. Despite its somewhat dark and otherworldly nature, Giratina might be intrigued by Ash's light - heartedness and his ability to make friends with all kinds of Pokemon. Dialga and Palkia could also be part of the harem. Dialga, with its control over time, might see Ash as an important factor in the future of the Pokemon world. Palkia, in charge of space, could be interested in how Ash navigates different regions and spaces in his journey. And don't forget about Ho - Oh. Ho - Oh is a symbol of hope and might see Ash as a bringer of hope in the Pokemon world, thus joining his harem.
Arceus is quite popular. Given that it's considered the creator of the Pokemon universe in the official lore, it often has a significant role in fanfictions. Mewtwo is also very common. Its powerful psychic abilities and complex backstory make it a favorite for fanfic writers to explore. Another popular one is Lugia. With its majestic appearance and its connection to the sea, it's often a central figure in many stories.
It could be Mew. Mew is known for its ability to transform and has a very mysterious nature. If Ash was Mew's son, he might inherit some of that mystery and the power to communicate with Pokemon in unique ways.
The Legend of the Brave is a very popular fantasy novel that tells the story of a brave man who participated in a battle against evil forces in order to protect his country and people.
