One possible scenario in this fanfic could be that James gets injured during a Pokemon battle. Maybe his opponent's Pokemon used a particularly strong attack that caught James off - guard. His team of Pokemon might then have to step up and protect him while he recovers. For example, his Weezing could create a smokescreen to keep the enemy at bay while James is tended to by his comrades.
One possible fanfic could be that Ash and his team are in a tough battle against a powerful opponent. Charizard, being overconfident, takes on a powerful attack head - on to protect Ash and the rest of the team. As a result, it gets seriously injured. Ash is devastated and has to quickly come up with a plan to both tend to Charizard's wounds and continue the battle. He uses his knowledge of Pokemon healing techniques he's learned over the years to stabilize Charizard and then makes a strategic retreat to a nearby Pokemon center.
One common plot could be Ash getting injured during a tough Pokemon battle. For example, when facing a powerful and rare Pokemon like Mewtwo. His Pikachu might try its best to protect him but Ash still gets hurt.

Maybe he stumbles upon a hidden lair of a group of Team Rocket - like villains who attack him.
By showing the severity of the injury. If a Charizard has a badly broken wing, it immediately creates tension as the reader wonders if it will ever fly again. The uncertainty of the Pokémon's future makes the story gripping.
One common theme is the journey of a Pokémon's recovery. For example, a Pikachu getting injured during a battle with a powerful wild Pokémon. The fanfic might focus on how its trainer takes care of it, like finding rare berries to heal it or taking it to a Pokémon center with special treatment. Another theme could be the bond between Pokémon strengthened through the injury. When a Pokémon is hurt, its friends might come to its aid, showing loyalty and friendship.
His injury might be caused by a malfunction of one of Team Rocket's inventions. For example, a new type of Pokeball - capturing device could backfire and injure James. This would cause chaos within Team Rocket as they try to fix the device and also take care of their injured comrade. Meanwhile, other characters might take advantage of Team Rocket's momentary weakness.
Misty would also be there to help. She's tough and resourceful. She might use her water - type Pokemon to cool down any burns if Ash has them, or to create a barricade against any approaching danger. Professor Oak could also play a role. He has a lot of knowledge and resources. He might send over some special medicine or a flying - type Pokemon to quickly transport Ash to his lab for proper treatment.
Maybe in the fanfic, Ash and his friends are exploring an ancient ruin. Charizard, being curious, wanders off and accidentally triggers a booby - trap. It gets severely injured.

Along the way, he meets a mysterious old trainer who gives him some advice on a rare and powerful healing method. But the method requires Ash to face his own inner demons and prove his worth as a trainer.
A group of poachers could be the antagonists. They might be after a rare Pokémon that Paul has or is known to be interested in. When Paul tries to stop them, they injure him.

It could be a new trainer who is jealous of Gary's skills and reputation. This trainer might set up a trap that causes Gary's injury in an attempt to prove himself better. For example, luring Gary into a dangerous area with false information about a rare Pokemon.
