The Avengers would likely be overjoyed. Tony might crack a joke about Coulson's 'resurrection' while also being secretly relieved. Steve would probably be very happy to see his friend again. Natasha might be a bit more reserved in her reaction but still glad. Thor would see it as a great sign and welcome Coulson back heartily.
Well, the Avengers would be shocked at first. But then, they'd probably be really happy. Thor might give Coulson a big, friendly slap on the back. And Black Widow would be curious about how he came back. Maybe Coulson's return would make the Avengers more determined to fight their enemies, since they got their friend back. It could also change the dynamics within the team, like more trust and better cooperation.
Some relationships would become stronger. For instance, Coulson had a good rapport with Captain America. Their friendship would be rekindled and might even grow deeper. With Coulson back, the Avengers would be more united as a whole. They would have more faith in the idea that no one is truly lost. And Coulson could act as a mediator in any potential disputes among the team members, like between Iron Man and Thor.
Well, some of them might be really surprised. Tony, for example, would probably crack a lot of jokes about Steve being young. He might say things like 'Cap, you were this cute little thing?' Natasha, on the other hand, would be more observant and start thinking about how this new information could be used in future strategies. Thor would probably just laugh heartily and pat Steve on the back, saying something like 'Tis an interesting discovery, young Steve!'
The Avengers might be initially shocked. For example, Iron Man could start by using his technology to find ways to help Hawkeye communicate better within the team. He might create special devices for him.
It would strengthen the team's bond. Coulson was always a sort of glue that held them together in a way. His return would bring back a sense of familiarity and comfort. They would trust each other more knowing that someone they thought was lost could come back.
Some Avengers might be protective. For instance, Captain America could immediately start giving Peter advice on how to better handle his dual identity and keep himself safe. He might offer training sessions to help Peter improve his skills as Spider - Man.
She might be overjoyed. Abby has a deep connection with Clarke, and in fanfiction, her first reaction could be pure elation. She would probably rush to see Clarke immediately, tears of happiness in her eyes.
Some Avengers might be surprised. Tony Stark, for instance, might be like 'Kid, you're younger than I thought!' and then start to adjust how he mentors Spider - Man. He could become more cautious about the risks he lets Spider - Man take.
Well, the Weasleys are a big family with strong values. Molly Weasley might be shocked at first but then turn into a very protective mother - in - law. Arthur might be a bit more reserved in his reaction but still show his support. Her brothers could have a mix of reactions, some might be overprotective and angry at the person who got Ginny pregnant, while others might be more understanding and focus on helping Ginny.
Well, if Clint discovers Coulson is alive in a fanfic, it could start with Clint being in disbelief. He might question how it's possible at first. Then, as he realizes it's true, he could feel a mix of emotions. There could be a sense of relief, because Coulson was like a friend and mentor to him. They might start to share stories of what they've been through since they last saw each other. And this new - found reunion could be the start of a whole new adventure for them, perhaps even leading to a new team - up against a common enemy that they thought they couldn't face without each other.
