One popular Fire and Ash fanfiction might be those that explore their adventures in uncharted regions. Maybe stories where they face new and powerful Pokemon.
One possible fanfic could be that Ash accidentally sits on a hot Pokeball which causes his butt to be on fire. He then runs around in a panic while his Pokemon try to figure out how to put the fire out. Pikachu might use Thunderbolt but that just makes things worse by electrifying Ash as well.
Ash can be developed by showing his growth in understanding different fire - type Pokémon's unique needs. For example, learning how to train a Charmander that is more stubborn than others. This shows his patience and adaptability as a trainer.
One idea could be Ash discovers a rare fire - type Pokémon that has powers beyond normal. He has to train it while facing challenges from Team Rocket who also want the Pokémon. Another plot could be Ash enters a fire - type Pokémon tournament and has to use his mastery of fire - types to defeat tough opponents.
Next, focus on the characters. Know their personalities well. Ash is known for his determination and love for Pokemon, and Fire might have its own unique traits. You should also consider how they talk and act. For example, Ash might use phrases like 'I gotta catch 'em all!' When it comes to writing, make sure to describe the scenes vividly. If they are in a forest, talk about the tall trees, the rustling leaves, and the Pokemon hiding in the bushes.
Ash might have trouble in areas with a lot of water or grass-type Pokemon. Training fire-types to handle different terrains and opponents would be part of his adventure. Plus, he might have to deal with rivals who have a better understanding of fire-type strategies.
As a fan of online literature, I can't give an accurate answer because it depends on many different factors such as the time period, geographical location, social background, etc. In addition, the popularity of the game also depended on the preferences of the players and the marketing strategy of the game company.
However, I can give you some relevant information to help you make your own judgment. Both Reverse Fire and Cross Fire were very popular shooting games with a large number of players and fans. However, CrossFire was better at marketing and operations. It had more servers and a wider audience. In addition, Cross Fire also introduced more game content and activities to attract more players. Therefore, from these aspects, Crossfire might be more popular.
However, the situation in 2021 did not seem to be good. Although it was a classic shooting game, the number of players seemed to have declined. Therefore, whether it is popular or not depends on many factors. You can make your own judgment based on your own preferences and observations.
Ash would likely be shocked at first. He's so used to seeing the good in people, especially fellow trainers. But then he'd probably get angry and determined to set things right. He has a strong sense of justice, so he wouldn't let the betrayal go unpunished.
Some fanfictions might have Misty betray Ash. Perhaps she gets lured by the promise of power or some valuable reward. She could be tricked into believing that Ash is no longer the friend she thought he was and that betraying him is for the greater good.
