Well, the team's reaction can vary depending on the specific circumstances in the fanfiction. Sometimes they are angry, especially if they think the injury was preventable. They'll do whatever it takes to get revenge on the cause of Keith's hurt if it was due to an enemy attack. And they'll also be there for Keith during his recovery, sharing stories, and trying to keep his spirits up so he can heal faster.
In some fanfictions, Keith might get hurt because of a betrayal within the team. This not only causes him physical pain but also emotional distress. His friends then have to work hard to regain his trust while also nursing him back to health, which is a very complex and engaging plot.
One alternative could be 'Voltron Keith and the Mysterious Alien Artifact'. This kind of fanfiction could involve Keith's encounter with a strange and powerful artifact, and how he and the team figure out its purpose and deal with the consequences. It's a much more positive and engaging theme compared to the disturbing one.
Keith initially reacts with defiance. He's a fighter, so he would likely struggle against his captors right from the start. He might try to break free of his restraints and attack any Galra who get too close, even if he's outnumbered.
Lance's family might be really welcoming. They could see that Keith is an important part of Lance's life and embrace him right away.
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.
One way is through fanfic recommendation platforms within the fandom. Moderators can ensure that only positive and appropriate fanfictions are recommended. They can also add tags like 'positive vibes', 'no disturbing content' etc. Additionally, established fanfic writers can lead by example and write more positive stories, which will inspire others.
A lot of the fanfictions about their kiss also explore the reactions of the other characters in the Voltron team. Some might be supportive, while others could be initially shocked or confused. The kiss can also be a symbol of a new era in the team's dynamics, as Keith and Lance's relationship changes. It can lead to interesting storylines about how the team adapts to this new development.
Yuki would likely be very concerned. He has a soft spot for Tohru and would probably rush to her side, trying to find a way to help. He might even blame himself if he thinks he could have prevented it. Kyo, on the other hand, would initially be angry, but that's just his way of showing worry. He would be more hands - on in getting her the help she needs.
Sasuke would initially be shocked. He's used to seeing Naruto as this energetic and somewhat indestructible force. But then he'd quickly shift to a more protective stance. He might cover Naruto while waiting for help. Sakura would be in a state of panic. She'd be running around trying to find someone to help, like a medical - ninja. Iruka would be the most level - headed. He'd assess the situation and if it was serious, he'd take Naruto out of the exam area to get proper medical treatment while also making sure Naruto doesn't feel like a failure for getting hurt.
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.
