One possibility is that Riley's injury would put their mission in jeopardy. The team would then have to decide whether to continue without him or wait until he recovers. This could lead to some internal conflict within the group as different members have different opinions on what to do.
In the fanfiction, Riley's hurt state could also be a catalyst for character development. Maybe he realizes his own vulnerability and becomes more cautious in future adventures. Or, it could strengthen his bond with the other characters as they show how much they care for him while he's injured.
Well, perhaps the other characters would immediately rush to his aid. They might use their knowledge of history and ancient remedies to try and heal him. For example, Ben could recall some medical knowledge from an old manuscript they once found during one of their adventures.
The team would likely be very concerned. Ben, being the leader - type, would probably take charge of the situation. He'd try to assess the severity of Riley's injury right away.
Perhaps Zoey getting hurt leads to a new friendship. There could be a character who she didn't really know before but who comes to her aid. This new friend could introduce Zoey to a whole new group of people or a new hobby. Also, her injury might make her more empathetic towards others who are in pain or going through tough times. She could start a support group at PCA for students dealing with injuries or hardships.
One possibility is that Igneel would immediately go into a protective mode. He might use his dragon powers to heal Natsu if he has such abilities. Since they have a strong bond, Igneel would be enraged at whatever caused Natsu to get hurt and would seek revenge. He could also stay by Natsu's side until he recovers, providing warmth and comfort as dragons are often associated with being a source of strength and protection.
One possibility is that the hurt Chase might be found by a new character in the fanfiction. This new character could have some unique healing powers. For example, a magical animal that can transfer its energy to Chase and make him better. Or maybe there's a hidden place with advanced medical equipment that the Paw Patrol discovers while trying to help Chase.
In the fanfiction, after Marshall gets hurt, the other Paw Patrol members would surely rush to his aid. Skye might use her helicopter to quickly bring Ryder to the scene. Chase could start securing the area to make sure no further danger is present. Rubble might start looking for any tools or first - aid supplies nearby. They all work together as a team, so they won't let Marshall be in pain for long.
Well, perhaps the Autobots would immediately come to the reader's aid. They might use their advanced technology to heal the reader's injuries. For example, Ratchet could use his medical tools to fix any broken bones or serious wounds. Then, they could take the reader back to their base for further protection and to figure out why the reader was hurt in the first place.
Well, he could be found by Scott or Stiles. They would probably take him to Deaton for treatment. Since Danny is a human in the Teen Wolf world full of supernatural beings, his injury might draw the attention of some unwanted creatures too.
Well, she might be nursed back to health by Jace. He could use his skills and knowledge of Shadowhunter healing to take care of her. Maybe he would also train her more gently after that to avoid further injury.
She could be taken to the royal healer. In the world of Sofia the First, there are magical healers who can use their powers to cure most injuries. Maybe the healer uses a special potion or spell to make Sofia better.
Maybe the enemy would see Naruto's injury as an opportunity to finish him off. But Naruto has a habit of surprising his foes. Even in his hurt state, he could pull off some unexpected jutsu. His friends could also use this situation to set up a trap for the enemy. For example, they could make it seem like Naruto is more injured than he actually is, luring the enemy into a false sense of security before attacking.
