Sakura would likely be initially terrified but quickly regain her composure. She is a trained ninja after all. She might start by assessing her situation, looking for any weaknesses in Team Hebi's defenses or any possible escape routes. Sakura would also try to talk her way out of the situation, using her intelligence to reason with Team Hebi. If that doesn't work, she would be ready to fight back using her taijutsu skills and any medical ninjutsu that could be used offensively, like her chakra - enhanced strength punches.
Sasuke would likely be devastated. Despite their past differences, Naruto was his rival and in a way, his closest friend. He might go into a deep state of regret and isolation. Sakura would be heart - broken. She loved Naruto, and his death would be a huge blow to her. She might become more withdrawn and focus all her energy on her medical ninjutsu. Kakashi would be filled with a sense of failure. He was Naruto's teacher, and he would feel responsible for not being able to protect him.
Sasuke would also be deeply affected. He might show his concern in a more reserved way compared to Naruto. He could be seen as being more determined to find a solution, using his skills and knowledge to try and save Sakura. He might even feel a sense of guilt if he thinks he could have prevented it in some way.
The team is devastated. Artemis might go into a deep state of grief and blame herself for not being there to protect him. Robin could become more withdrawn and focused on finding out who or what caused Wally's death. Superboy might struggle with anger, feeling like he should have been stronger to prevent it.
Sakura might be in shock at first. Unable to believe that Naruto, who has always been so strong - willed, could have ended his own life. As she processes it, she could become angry, not at Naruto but at herself and the situation that led to this tragic outcome.
The Paw Patrol team would initially go through a period of disbelief. Rocky might isolate himself as he tries to come to terms with Marshall's death. Zuma would be quieter than usual, missing his friend. Ryder would have to step up and be strong for the team, but inside he'd be deeply hurt. They would also likely hold a memorial service for Marshall, with each pup sharing their favorite memories of him. This would help them start to heal and find the strength to continue their important work in Adventure Bay.
Naruto would likely be devastated. His old team was an important part of his early life in the ninja world. He might initially go into a state of shock, unable to believe that they are gone. Then, his grief could turn into anger, vowing to find out who was responsible and make them pay.
Sakura would be heartbroken. She'd likely spend hours upon hours by Naruto's side, trying to jog his memory with stories of their adventures together. She might even get a bit overbearing in her attempts. Sasuke, who has his own complex relationship with Naruto, would be conflicted. He'd see Naruto's forgetfulness as a sign of weakness at first but then realize the importance of their bond. Kakashi, being the experienced leader, would start by observing Naruto carefully to see exactly how much he has forgotten and then start a systematic process of helping him remember.
Sakura could also use her strength in combat. In the fanfiction, she may have developed new jutsu or fighting techniques that she uses to protect her teammates and help them achieve their goals. For example, she could use her precise chakra control to enhance her attacks and defenses, making her a valuable asset in battles.
