A good team could be Pikachu for its popularity and electric type moves which are useful in many situations. Charizard as it's a powerful fire type. And Bulbasaur which can cover different types with its grass and poison attacks. These three are classic and can handle a lot in the story.
The story of Pokemon Fire Red is about a young trainer's journey in the Kanto region. The trainer starts with a single Pokemon and travels across various cities, battling Gym Leaders to earn badges. Along the way, they encounter Team Rocket causing trouble, like stealing Pokemon. Eventually, they aim to compete in the Pokemon League and become the Champion.
A good team could be Sprigatito, Fuecoco, Pawmi, Rookidee, Nacli, and Hoppip. Sprigatito has some useful grass - type moves early on. Fuecoco is a solid fire - type. Pawmi is an electric - type with decent power. Rookidee is a fast flying - type which can be very helpful in battles. Nacli is a rock - type that can take hits well. Hoppip is a grass - and flying - type that can be useful in different situations.
Well, in my opinion, a solid team for the Pokemon Shield story would be the following. Firstly, have a Zamazenta. It's a powerful Legendary Pokemon with great stats. Then, add a Centiskorch. It's a Fire - type with high attack power. Next, include a Grimmsnarl. It has good special attack and can be quite a tank. Also, consider a Duraludon. It's a Steel - type which is great for defense against many types. Finally, have a Mr. Rime for its ice - type moves and its unique look. This combination gives you a good mix of offense, defense, and different types to handle various situations in the story.
Well, when it comes to a good team for the story in Pokemon Sword, you can't go wrong with Zacian, the legendary of the game. Along with Zacian, having a team of Scorbunny (evolved into Cinderace) for its speed and firepower, Snorlax for its bulk and power, Lucario for its fighting and steel typing which is great against many opponents, Gardevoir for psychic support, and Flygon for its ground and flying type combination which helps in traversing different terrains and battles.
In a Pokemon Red join Team Rocket fanfic, the main character could be a disillusioned trainer. Maybe they've lost a few too many battles and are looking for a new way to gain an edge. Team Rocket seems like an alluring option. They join up and are immediately thrust into the world of illegal Pokemon trading. However, they soon meet a friendly Pokemon that shows them kindness despite their new allegiance. This makes them question their decision to join Team Rocket and they start to think about how they can use their new position to actually help the Pokemon instead of harming them.
For the story mode in Pokemon Sword and Shield, Sobble, Grookey and Scorbunny are great starters. Sobble can turn into a powerful water - type, Grookey into a strong grass - type and Scorbunny into a fire - type. They can cover a wide range of types as they evolve.
Naruto himself would be a great addition. His determination and ability to never give up would translate well into being a Pokemon trainer. He could bond quickly with his Pokemon. Also, Kakashi would be good. His intelligence and strategic thinking would help in planning battles. And then there's Shikamaru. His lazy - but - brilliant mind could come up with unique battle strategies using the Pokemon's abilities.
Well, for the story in Pokemon Sun, I'd recommend starting with the starter Pokemon that suits your playstyle, be it Rowlet for its grass - flying type which is useful against many early opponents. Then add a water type like Mudkip (if obtainable) for its versatility. Also, having a normal type like Eevee can be great as it can evolve into different useful forms later. And don't forget about a flying type like Pidgey which can help with scouting and quick getaways. Another good addition could be a psychic type like Abra for its strong special attacks later on.
A good team could be Zacian, Rillaboom, Inteleon, Corviknight, Dragapult, and Toxtricity. Zacian is a very strong Legendary Pokemon. Rillaboom is a great Grass - type with powerful attacks. Inteleon is a reliable Water - type. Corviknight can provide good flying support. Dragapult is a fast and strong Dragon - type. Toxtricity can deal with different types of opponents with its dual - type nature.
