The characters in Harry Potter might be quite shocked at first. Hermione would probably be very curious about Wonder Woman's world and powers. Ron might be a bit jealous at first but would come around. In the DC side, Wonder Woman's friends like Steve Trevor would be protective at first. But as they see how happy she is with Harry, they would accept him. The wizarding community would have to adjust to having a superhero as part of their world through marriage, and the superheroes would have to accept a wizard into their midst.
She could be devastated. Wonder Woman might go into a period of mourning, isolating herself from others as she grapples with the loss. She was used to having Batman as an ally, and his death would leave a big hole in her life.
Another reaction could be that Marinette pretends to cooperate with Adrien at first. By doing this, she can buy time and look for an opportunity to escape or get help. She might act as if she is okay with what is happening while secretly planning her next move, like leaving a clue for someone to find her or finding a way to disable Adrien temporarily.
Marinette can react by standing up for herself. She might confront Chloe directly and tell her that her actions are wrong. This shows Marinette's strong character.
Wonder Woman is a fictional superheroine. In the context of 'Wonder Woman The Real Story', she is likely presented with her origin, powers, and significance in the DC Comics universe. She has superhuman strength, speed, and combat skills, and is an iconic symbol of female empowerment.
Marinette could react with disbelief and assume it's some sort of joke at first. But when she realizes Adrien is serious, she might start to get really nervous. She could start fidgeting with her hands or her hair. If she's in the middle of doing something, like working on a design, she might drop her tools in surprise. Once the shock wears off, she would most likely be very happy and accept his invitation, but it would be a very flustered and excited acceptance.
Marinette might be initially shocked when Adrien steps in to protect her. She could be very grateful and show it with a shy smile or a simple 'Thank you.'
Naruto himself would be deeply hurt. He is a character who values friendship and loyalty highly. He would probably try to talk to Wonder Woman first, to understand why she did it. If she doesn't give a satisfactory answer, he would be forced to defend himself and his world. His other comrades like Sakura would be ready to back him up, and they would be angry at Wonder Woman for breaking the trust. As for the other side, Wonder Woman's friends like Steve Trevor might be confused and try to mediate at first, but if the situation gets worse, they might also side with her.
