One possible strongest team could be Pikachu, Charizard, Greninja, Lucario, Sceptile, and Infernape. Pikachu has been with Ash since the start and has a strong bond. Charizard is extremely powerful. Greninja has its unique form and great combat skills. Lucario is a very capable fighter. Sceptile was a strong addition to Ash's team in Hoenn. And Infernape showed great power in Sinnoh.
One of the popular fanfics where Ash calls the strongest Pokémon could be those where he summons Arceus. In some fanfictions, Ash might have a special connection with Arceus, the so - called 'God of Pokémon'. This could lead to epic battles and adventures as he teams up with the most powerful being in the Pokémon universe.
In a fanfiction of Ash in the Unova League, it could focus on his relationships with his Pokemon during this journey. Maybe Pikachu has a special moment of growth, or he catches a new and rare Pokemon that becomes crucial in his battles in the league.
The fanfic about Ash winning the Alola League is great. Ash winning is a big deal as it shows his development as a trainer. In the Alola region, he faced many challenges, and to overcome them and win the league is a huge achievement. The fanfic probably delved deeper into the emotions of Ash and his friends during the league battles, making it a more immersive experience for the readers.
One idea could be that Ash's victory in the Alola League is due to his strong bond with his Pokémon. His Pikachu, for example, could have evolved a new move during the final battle that gave them the edge. Another idea is that Ash's experience from all his previous regions finally culminates in this victory, and he uses strategies he learned along the way.
In the Unova League in the Pokemon series, Ash winning is quite an exciting concept in fanfiction. It shows his growth as a trainer. Maybe in this fanfiction, he finally overcame all his opponents with his strong team, strategic thinking and unwavering determination.
Ash is obviously a very common character as the title includes his name. Pikachu, his trusty partner, is also likely to be there. His friends like Brock and Misty often appear as well. They might support Ash during his league journey or have their own sub - plots related to the league.
Perhaps he defeats some of the Elite Four members who are participating in the league. They are known for their strength, so it would be a huge accomplishment. And of course, any recurring rivals from his past adventures like Trip or Paul.
There might be a fanfiction where Ash teams up with some unexpected trainers in the Kalos League. They combine their strategies and Pokemon to take on tough opponents. For example, he could partner with a trainer who specializes in Fairy - type Pokemon, which are quite prominent in Kalos. This could lead to some really creative battle scenarios and character interactions.
The fanfiction might start with Ash feeling more determined than ever. He could go on a journey to find rare Pokémon or special items to boost his team. Along the way, he faces many challenges and meets new trainers. In the Pokémon League, he uses his experience from all these encounters. His Pokémon's diverse movesets and his own quick thinking in battles lead him to victory.
