His friends, like Kai, would be very protective. Kai might get angry and rush into battle to avenge Lloyd's injury. Jay would probably be more worried and try to use his technical skills to find a solution to heal Lloyd.
One common theme is Lloyd's struggle with his identity. When he's hurt, it often intensifies his self - reflection. Another theme could be his relationship with his friends. His being hurt might test their loyalty and how they support him. Also, themes related to his powers and how being hurt affects his ability to use them are quite common.
When Lloyd gets possessed, his character can take on a whole new personality. He might start to oppose his friends and the things he once fought for. For example, he could use his powers against the other Ninja. This change is not just about his actions but also his way of thinking. He might view the world from the perspective of the possessing entity, which is often dark and power - hungry. His relationships with his friends also become strained as they try to figure out what's wrong with him and how to save him.
One common plotline could be Lloyd getting hurt during a battle with a powerful enemy like the Overlord. His friends then have to figure out how to protect him while also fighting off the threat. For example, they might find a hidden place to keep him safe while they gather resources to heal him.
One interesting plot development could be Lloyd's struggle to regain control. As he's possessed, his friends might initially not realize it and think he's just acting out of character. Then, they gradually notice the strange behavior and start to investigate. This could lead to a race against time to save Lloyd from the possessing force.
If Lloyd is kidnapped, it could be a plot by the villains to gain some sort of advantage. Maybe they want to use Lloyd as a bargaining chip to get the other ninja to give up their elemental powers. The ninja would then have to decide whether to risk everything to save Lloyd or come up with a more clever plan to outwit the kidnappers.
One great 'Ninjago Lloyd fanfiction' is 'The Golden Ninja's New Adventure'. It takes Lloyd on a journey to discover a hidden power within him that's not related to his usual green ninja abilities. It's really exciting as it shows a different side of Lloyd.

Another option is FanFiction.net. Many fans post their creative works there, and you might find some interesting stories about Lloyd in a hurt or vulnerable state.
One common scenario could be during a battle with the villains. For example, when facing the Serpentine, Jay might get caught by their venomous attacks which could hurt him badly. Another situation could be an accident while training with his fellow ninjas. Maybe he misjudges a move and ends up crashing into something hard, like a rock or a wall in the training area.
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.
