Donnie would spring into action with his scientific knowledge. He'd start looking for ways to treat Mikey's injuries, whether it's patching up a wound or trying to figure out if there are any internal injuries. He'd be constantly monitoring Mikey's condition and making sure he has everything he needs to recover.
Leo would likely take charge immediately. He'd assess the situation and start giving orders on how to help Mikey. He'd be calm on the outside but worried on the inside.
Leo would probably take charge immediately. He'd be focused on getting Mikey to safety and finding a way to treat his injuries. He might be blaming himself a bit for not being there to protect Mikey better.
Raph would be the first to show his concern through anger. He'd be mad at himself for not protecting Leo better and also at the situation that led to Leo's injury. Mikey would be visibly distraught, constantly by Leo's side trying to cheer him up. Donnie would be all business, using his scientific knowledge to figure out the best way to treat Leo's wounds and help him recover.
In a fanfiction, Mikey might get hurt during a mission to infiltrate a Kraang base. He could be detected by security systems and get zapped by some sort of electric defense mechanism. This would leave him weak and in pain. His brothers would need to carry him out of there and find a way to reverse the effects of the zap. They'd be desperate to get Mikey back to his normal, energetic self.
Splinter, as their sensei and father figure, would offer wisdom and comfort. He might have some traditional methods to help with Donnie's pain and healing. And he would also use this as a teaching moment for all of his sons about the importance of caution and looking out for each other.
Raph usually gets really angry. He blames himself for not being there to protect Leo or he gets mad at the enemy who hurt Leo. He'll be the first to want revenge and will be very protective of Leo while he's injured.
One possible scenario could be that Mikey gets hurt during a fight with the Foot Clan. Maybe he underestimated an opponent and got a nasty cut on his arm. His brothers would then rush to his side, with Donnie trying to patch him up as quickly as possible while Leo and Raph stand guard, ready to fend off any further attacks.
His friends would be extremely worried. They might immediately drop whatever they are doing to rush to his side. For instance, Thomas would be right there, trying to assess the situation and figure out how to help. He would be filled with a sense of urgency and determination to get Minho the care he needs.
Well, first, you should check the major fanfiction platforms. AO3 is known for having a wide variety of fanfictions, so it's a good place to start. Enter the title in the search box carefully. FanFiction.net is also a possibility. Sometimes, smaller, more niche TMNT - focused fanfiction communities might also have it, but those can be harder to find. You might need to do some more in - depth searching on TMNT fan forums to see if anyone has a link or knows where to find it.
I'm not sure specifically as I haven't read this particular fanfiction. But it might be about Mikey from the Teenage Mutant Ninja Turtles getting some sort of skin condition like shellacne. It could involve his friends helping him deal with it, or his own journey in handling this new and unexpected situation.
Well, Leo would be the calm and collected one showing concern. He'd organize everything from Mikey's care to the security of their lair. He might also give Mikey pep talks about getting better soon. Raph would show his concern through his actions. He'd be the first to volunteer to go out and get anything Mikey needs, whether it's medicine or his favorite food. And Donnie would be constantly hovering over Mikey with his medical equipment. He'd be making sure Mikey is taking the right medicine at the right time and monitoring his progress closely. All of them would also share memories with Mikey to keep his spirits high.
