I think Salamence would be quite challenging. It's a very powerful and aggressive Pokemon. Ash would need to have a really strong team to weaken it first. Also, its flying ability gives it an advantage in battle, making it hard for Ash to land a final blow for the catch.
I'm not sure specifically what this fanfiction is about as there could be many different interpretations. It might be about a character named Ash who has an encounter or relationship with a pseudo - legendary Pokémon in a fictional story created by a fan.
One interesting Pokemon pseudo - legendary fanfiction could be about a trainer's journey to catch all the pseudo - legendaries. They might face unique challenges like rival trainers specifically targeting these powerful Pokemon.
I'm not sure specifically as there could be many different interpretations. It might be about Ash from the Pokémon world having a Pokémon that is considered a pseudo - legendary as his starter Pokémon. Maybe it details his adventures with this special starter in a unique and creative way that diverges from the normal Pokémon storylines.
You could try looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a large collection of Pokémon - related fanfictions.
Well, start with the big fanfiction platforms. FanFiction.net is a well - known place where a lot of Pokémon - related fanfictions are hosted. Another option is AO3. They have a large collection of fan - created works. Sometimes, Pokémon fan communities on social media might also be able to point you in the right direction. You could post a query in a relevant Pokémon fan group on Facebook or Reddit, asking if anyone knows where to find this specific fanfiction.
You need to create a plot. It could be about a trainer who discovers a hidden power within a pseudo - legendary Pokemon. Develop your characters well. Give them distinct personalities. If your trainer is a girl, she could be brave but also have a soft side for her Pokemon. Outline the story, including the beginning, middle, and end. Maybe start with the trainer finding an injured pseudo - legendary and then build up to a big battle at the end.
Ash could develop his character in Sinnoh by becoming more strategic in his battles. Since Sinnoh has a variety of strong and unique Pokemon, he'd need to think more carefully. Misty could develop by becoming more independent. Maybe she takes on some solo adventures in Sinnoh, away from Ash for a bit, and this helps her grow as a trainer.
His first Sinnoh Pokémon could be a Chimchar. Imagine Ash finding Chimchar being bullied by some other Pokémon. Ash steps in and Chimchar decides to join him. Chimchar's energetic and mischievous nature would add a lot of fun to Ash's Sinnoh adventures as it grows and evolves into an Infernape.
Well, a great plot might be that Ash enters a special tournament where the grand prize is a chance to catch a Pseudo - Legendary Pokemon. He has to battle tough trainers along the way. Also, it could be that a Pseudo - Legendary Pokemon has some sort of unique ability that Ash discovers he needs to help solve a big problem in the Pokemon world. Maybe it can control a powerful energy source, and Ash must earn its trust to use that power for good.
