One possibility is that Ash's Ekans could be a special one with unique abilities. Maybe it has a hidden power that helps Ash in battles against stronger opponents. For example, it could have a super-effective type of attack that is not common among Ekans, like a special poison - type move that can paralyze opponents for a long time.
Well, if Ash starts with an Ekans, his team dynamic would be very different. Ekans is a snake - like Pokemon, and it might not get along well with some of the more energetic or flighty Pokemon at first. For instance, Pikachu might be a bit wary of it since they are so different in nature.
He could have a Froakie. It's a common and cute starter in Kalos. Maybe also a Skiddo for traveling across the Kalos landscapes. And a Bunnelby would be a nice addition for its digging abilities.
If Ash starts with a legendary pokemon such as Rayquaza, it could be that there are abnormal weather patterns in the Pokemon world. Rayquaza has the ability to control the weather. Ash and Rayquaza team up to figure out what is causing these extreme weather changes. Along the way, they meet other trainers who are also affected by the weather problems. Ash has to prove that he is worthy of having a legendary pokemon by using Rayquaza to restore balance to the weather.
Well, one possibility could be that Ash's Ralts has a special ability that sets it apart from other Pokémon. Maybe it can communicate with Ash in a unique way, like through emotions. This could lead to Ash having a deeper understanding of Pokémon in general.
Well, obviously Ash is one of the main characters. He's the protagonist of the Pokémon series and his journey in Alola is the focus. Pikachu is also a main character as Ash's loyal Pokémon partner. In Alola, there could be new friends like his classmates from the Pokémon school, such as Kiawe, Lillie, and Sophocles, who would also play important roles in the fanfiction.
In this fanfiction, Ash could start in a mysterious forest and spot a shiny Celebi. Celebi, being a time - traveling Pokemon, could take Ash on a journey through different time periods in the Pokemon world. He might see how the Pokemon world has evolved over time, meet some of his ancestors or future versions of himself, and have to solve various problems in each time period to keep the balance of the Pokemon world.
Well, one possibility is that Ash meets the shiny ghost pokemon early on his journey. Maybe it's a Gastly that has some special power. Ash could then try to befriend it, facing challenges from other trainers who also want this rare pokemon. The shiny Gastly might lead Ash to an old, haunted place full of secrets about pokemon evolution or some long - lost pokemon techniques.
One great aspect of a fanfiction where Ash starts in Kalos is that the environment is so different from what he's used to. The Kalos region has its own set of challenges, like the mega - evolution phenomenon. Ash could get involved with researching about it early on. He might also form new friendships with characters like Serena right from the beginning, and together they could embark on a journey filled with new discoveries and exciting battles.
