The ponies in Ponyville would also show concern. The little ponies who often play with Spike would be sad and bring him little gifts like flowers or their favorite sweets. The older ponies would offer their wisdom on how to heal and take care of Spike. Overall, Spike getting hurt would create a wave of worry, care, and unity among the characters in the MLP world.
The rest of the Mane 6 would also be very affected. Rainbow Dash, for instance, would be angry at whatever or whoever caused Spike to get hurt. She would be eager to take action and get revenge if it was another character's fault. Pinkie Pie would be sad and would try to cheer Spike up with her parties and jokes, but deep down she would be really concerned. Rarity would fuss over Spike, trying to make him as comfortable as possible and using her sewing skills to make bandages or something to help with his injuries.
Twilight Sparkle would likely be extremely worried. Since she raised Spike, she would feel a deep sense of guilt, as if she failed to protect him. She might even blame herself for putting Spike in a situation where he could get hurt in the first place. She would probably rush to find a way to heal him, using all of her magic knowledge.
They would feel a mix of guilt and anger. Guilt because they might think they could have prevented his injury. Anger towards the person or situation that caused it. Eric would be especially emotional, as he and Ryan are close friends. They would all rally around Ryan, and this would strengthen their bond as a team.
The other characters would likely be very worried. Stella might be especially emotional as she's one of Flora's closest friends. She could be seen crying and constantly hovering around Flora, trying to make her feel better. Musa would probably be quiet but deeply affected, using her music to try and soothe Flora's pain in a way.
Vivi would likely feel a great deal of guilt. She might blame herself for putting Luffy in harm's way. After all, he got hurt because of her. This guilt could drive her to be more proactive in helping him recover.
Hotch would feel a great sense of responsibility. He's the leader, and Reid getting hurt might make him question his decisions that led to the situation. He'd be very protective and focused on getting Reid back to full health.
There could be fear as well. Seeing Naruto injured, Sakura might be afraid of losing him. This fear could drive her actions in the fanfiction, whether it's in finding a cure for his injuries or in taking revenge on those who hurt him. It would also add more depth to their relationship as she grapples with these complex emotions.
Cam would be in a state of worry but also in her role as the boss, trying to keep things in order. She would be making sure Brennan gets the best medical treatment available at the Jeffersonian. All the characters would feel a sense of loss and unease, as Brennan is such an important part of their team and their lives.
For Pepper Potts, it would be devastating. She has been Tony's love interest, so she would be heartbroken. She might go into a deep depression and struggle to carry on with her life. For Rhodey, he would feel a great sense of loss. As Tony's long - time friend and military ally, he would probably blame himself for not being able to protect Tony.
Simon might be in a bit of a panic. Since he's her friend and also not as used to the dangerous situations as the other Shadowhunters. He'd try to do whatever he can to help, like getting help from more experienced Shadowhunters or trying to comfort Clary while she's in pain.
The other characters' reactions can vary. Pixal, if she's around, would use her technological knowledge to see if there are any internal damages to Jay, especially if it's related to his electrical components. The villagers of Ninjago might also show their support. They could bring food or offer shelter for Jay to recover. The reaction of the villains would depend on the situation. Some might see it as an opportunity to finish Jay off, while others might be impressed by his courage in getting hurt while fighting them.
The whole crew would be in shock. Kanan was an important part of the team. Sabine, for instance, would feel a sense of guilt, wondering if there was something she could have done to prevent his death. Zeb would be solemn, and the group's dynamic would change completely. They would have to find a way to move forward while still mourning Kanan, and it would be a long and difficult process. Their hope and morale would take a big hit, but they might also find new strength in avenging his death or continuing his legacy.
