The other characters' reactions would be complex. Hawkeye was a beloved member of the team. His death during a Kree invasion would send shockwaves. Characters like Wanda Maximoff, who might have had a close bond with Clint, could be emotionally shattered. She might use her powers in an erratic way, either out of grief or a desire for revenge. Vision, on the other hand, might try to use his logical approach to analyze how this happened and how to prevent further losses. The team's dynamic would be severely disrupted. Some might become more withdrawn, while others would try to fill the void left by Clint, but it would be a difficult and emotional process for all of them.
One possibility could be that his death serves as a catalyst for the remaining heroes to fight even harder. They might become more united in their grief and determination to stop the Kree invasion. His skills and knowledge would be sorely missed, but his sacrifice could inspire new heroes to step up.
Skye would be devastated. She had a very complex relationship with Ward. There was a time when she trusted him and even had feelings for him. His death would likely make her more withdrawn and distrustful at first. Coulson would be conflicted. He knew Ward was a troubled soul and had tried to rehabilitate him in a way. His death would be a failure in that regard for Coulson.
Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
Cap would be shocked at first. He trusts his comrades, and for the Clint team to betray him would be unexpected. He would likely feel a sense of betrayal and anger. He might start by trying to isolate the situation, to keep the knowledge of the betrayal from causing too much unrest in the Avengers. Then he would try to find a way to stop the Clint team from causing more harm, whether through negotiation or combat.
Marinette's friends, like Alya, would be heartbroken. Alya, being Ladybug's biggest supporter, would probably feel a sense of loss and confusion. She might start to investigate Ladybug's death, trying to figure out what really happened. The other classmates would also be affected, with the mood at school becoming very somber.
His Pikachu would be heartbroken. Pikachu has been with Ash from the very beginning, and it would likely go into a state of deep depression. It might not eat or interact with others for a long time. Other Pokémon like Charizard would also be extremely sad. Charizard, which has a strong bond with Ash, might fly off on its own, looking for a place to grieve in solitude.
The reaction of the Dragon Ball characters to Thanatos' invasion would be complex. Goku, as always, would approach it with a sense of adventure and the desire to test his limits. He would be the first to reach out to Thanatos in combat. Vegeta would be seething with anger at the thought of someone invading their territory. He would fight with all his might, using his Galick Gun and other powerful attacks. For the younger characters like Trunks and Goten, they would be inspired by the older fighters. They would follow their lead and contribute in their own ways. The non - Saiyan characters like Krillin and Tien would use their unique fighting styles and skills. The Dragon Ball universe has a long history of coming together against threats, and this would be no different.
The other characters' reactions could vary widely. His close friends in the fanfic might be in a state of panic, crying and not knowing what to do. Enemies, on the other hand, might see it as an opportunity to take advantage, or they could also be secretly worried depending on the complexity of their relationships. And there could be those characters who are just bystanders, shocked at first and then trying to figure out what happened.
Harry would probably be initially confused but also intrigued by Clint Barton. He might see Clint as a new source of knowledge and a different kind of role model compared to the wizards he's used to. Hermione would be eager to learn about Clint's world and might try to find a way to combine his skills with magic. Ron, on the other hand, might be a bit more skeptical at first but would gradually come around as he sees the benefits.
Clint would first go into shock for a short moment, but then his training would kick in. He'd be in a state of pure rage on the inside but keep a cool exterior to better assess the situation. He'd start by retracing his family's last steps, looking for any clues. He might also use his connections in the criminal underworld to see if anyone has heard anything about the kidnappers. He'd be constantly thinking of ways to outsmart the kidnappers and rescue his family, all while being haunted by thoughts of what could be happening to them.
