The characters from Big Hero 6 would have diverse interactions. Hiro, being the intelligent inventor, would start by asking a lot of questions to Joy and the others about how their system of controlling Riley works. Baymax would immediately notice if any of the emotions were feeling unwell, like if Sadness was overly sad, and would offer his support. Go Go would likely bond with Anger over their shared determination. Fred would probably try to get Fear to be more adventurous, which could be both good and bad. Wasabi would try to create a more organized environment for the emotions, as he is used to order in his own life and in the Big Hero 6 team's operations. All of these interactions would be a mix of learning, sharing, and sometimes butting heads as they all come from different worlds.
Hiro would likely be very curious about the emotions. He would try to study them and understand how they work. Baymax, on the other hand, would probably be very gentle and try to comfort any of the emotions that seem distressed, like Sadness. Go Go might be a bit impatient with the more timid emotions like Fear, but she would also respect their role. Fred would probably be excited to meet these new 'creatures' and want to be friends with all of them immediately. Wasabi would be a bit cautious at first, but then warm up to them.
The interaction between the characters would be full of surprises. Consider Baymax and Joy. Baymax is all about helping and healing, and Joy is about spreading positive feelings. They could team up to make people in San Fransokyo feel better, Baymax by providing physical care and Joy by influencing their emotions. Then there's Hiro and Anger. Hiro might initially be annoyed by Anger's brashness, but over time, he could learn to use that energy in his battles. The other characters like Fred and the other emotions would also have their own unique interactions. Fred might try to show off to the emotions with his monster knowledge, and the emotions would either be impressed or find it a bit silly depending on their nature.
Naruto would probably be very excited to meet the Big Hero 6 crew. He'd be eager to learn about their technology. Hiro might be a bit intimidated by Naruto at first but would soon realize they could be great friends. GoGo would be interested in Naruto's speed and agility, and might challenge him to a race. Baymax would be very curious about Naruto's body functions, especially related to chakra. Sakura could bond with Honey Lemon over their shared interest in science, although Sakura's knowledge is more in the medical - ninja field.
In a 'Big Hero 6' and 'Inside Out' crossover fanfiction, perhaps Riley visits San Fransokyo. During her visit, she witnesses an accident that Big Hero 6 is responding to. The chaos and destruction make Sadness start to surface strongly in her. Baymax senses her distress and tries to help her. This leads to the team inviting Riley to their lab to cheer her up. Inside their lab, the emotions are fascinated by all the high - tech gadgets and start interacting with them, causing some comical and unexpected situations as they blend the two very different worlds of technology and emotions.
Perhaps there's a glitch in Baymax's system that causes him to project Riley's emotions as holograms. Hiro is confused at first but then realizes that these emotions are from someone else. They track the source of the connection and end up in Riley's mind. There, they find that the emotions are in chaos because of the sudden link to Baymax. The Big Hero 6 characters use their skills to help the Inside Out characters restore order. Hiro and Baymax help Joy understand how to better manage the positive emotions while the rest of the team helps the other emotions like Sadness not feel so left out or misunderstood.
The heroes in My Hero Academia would be in awe of Spider - Man's abilities. His ability to climb walls and swing from buildings would be something new to them. They might try to incorporate some of his moves into their own fighting styles. Midoriya would look up to Spider - Man as another symbol of hope, just like All Might.
The students of U.A. High would bring a sense of youthful energy and naivete to the interaction. They'd be curious about the powers of the Avengers and their technology. The Avengers, in turn, would be protective of the young heroes at first. For instance, Hulk might initially see the students as too fragile. But as they face challenges together, they'd develop mutual respect. The different personalities, from the cocky Bakugo to the calm and calculating Shoto, would create a rich tapestry of character interactions with the diverse Avengers.
Naruto and Hiro are likely to interact. Naruto's enthusiasm and Hiro's intelligence would create an interesting dynamic. They could both inspire each other in different ways, like Naruto inspiring Hiro to be more bold and Hiro teaching Naruto about science and technology.
The quirks in My Hero Academia are often very physical and unique to each individual. In a crossover, Uraraka's zero - gravity quirk could be used in space battles in the Star Wars universe. She could disable enemy ships by making them weightless. On the other hand, the Force abilities in Star Wars, like mind control and precognition, could give the My Hero Academia characters an edge in combat. For example, Todoroki could use his ice quirk in combination with a Jedi's precognitive ability to anticipate his opponents' moves and freeze them in place before they can act.
Superman and All Might would probably have a great deal of respect for each other. They are both symbols of hope in their respective universes. All Might might be a bit in awe of Superman's natural powers, while Superman would admire All Might's determination despite having a quirk that was slowly fading. They could exchange stories about their battles and how they inspire others.
The hero could interact with the garden itself as if it were a character. He might listen to the rustling of the leaves for signs or talk to the plants. For example, if he's lost, he asks the tall oak tree for directions in a way that the tree somehow communicates back.
