In a fanfiction, the Kirby characters could be really curious about the Personas. They might see them as some kind of super - power that they want to learn about. And the Persona 5 characters could be charmed by Kirby's cuteness. They could teach Kirby about their world's rules and Kirby could introduce them to the fun things in his world, like eating delicious fruits and playing in the meadows.
Joker, the main character of Persona 5, might be initially cautious around Kirby. Kirby's round and friendly appearance might make Joker lower his guard after a while. He could then show Kirby how to use a Persona, if Kirby was interested.
The characters would likely have a mix of admiration and friendly rivalry. For example, the cool and collected protagonist of Persona 5 might be intrigued by the more laid - back nature of the Persona 4 protagonist. Meanwhile, the Persona 3 protagonist, with his more somber and serious demeanor, could initially seem a bit intimidating to the others. But as they get to know each other, they would start to bond over their shared experiences of fighting Shadows and protecting their worlds.
The characters would likely be initially cautious. For example, Yu from Persona 4 might be a bit reserved when meeting Joker from Persona 5, but as they learn about each other's goals, they would start to trust. Yosuke might be excited to see the more high - tech Metaverse compared to the TV World, and he could bond with Ryuji over their shared love for adventure. Chie would probably challenge Ann to a fight at first, thinking she's just a pretty face, but then realize Ann's strength.
The interaction could be full of humor and action. Imagine Skull from Persona 5 challenging Saitama to a fight, not fully understanding the extent of Saitama's power. Saitama would probably just knock him out with one punch in a comical way. But then the Persona 5 characters could show Saitama the value of teamwork and strategy, which he might not be used to in his solo fighting style. They could also introduce him to their world, and Saitama could introduce them to the strange and wacky world of One Punch Man heroes and villains.
When Kirby encounters a Pokemon like Charizard, at first Charizard might be a bit intimidating. But Kirby's fearless nature would make him approach Charizard. Charizard could be impressed by Kirby's courage and might give Kirby a ride on its back. They could then work together in battles, with Charizard providing the firepower and Kirby using his copied moves to support and finish off opponents.
Some characters might not get along so well. For instance, a more serious Persona character might find Joker's carefree attitude a bit off - putting. However, as they face challenges together, they would start to understand and respect each other. The Persona characters could introduce Joker and his friends to the concept of the Collective Unconscious in more detail, and the Phantom Thieves could show them how to use their skills in a more urban, modern - day setting. There would be a lot of banter and friendly competition between the two groups as they learn from each other.
Definitely Naruto. Naruto would be curious about Kirby's abilities and would probably want to be friends right away. They could have some fun training sessions together, with Kirby showing off his inhaling skills and Naruto his new Rasengan variations. Also, Sakura might interact with Kirby. She could be initially a bit skeptical but would come around when she sees how Kirby can be helpful in medical situations by using his powers to quickly gather medicinal herbs or supplies.
One idea could be that Kirby swallows a Persona and gains its powers. This would lead to some really interesting battles and interactions. Kirby could then use the Persona's skills in the Dream Land setting, creating a whole new dynamic.
Joker could be a Slytherin. He's very resourceful and has a certain cunning about him, which are Slytherin traits. He's able to strategize well in battles, much like how Slytherins are known for their ambition and ability to achieve their goals through different means.
In a fanfiction, Naruto would likely be very curious about the Thundermans' superpowers. He might constantly ask them how they got their powers and if they could teach him. The Thundermans, on the other hand, would be fascinated by Naruto's ninja way. For example, Phoebe might admire Naruto's determination and sense of justice. They could start by being a bit wary of each other, but as they get to know one another, they would start to work together. Naruto could show them some of his cool ninja tricks, like walking on water, and the Thundermans could show Naruto how to use modern gadgets.
Naruto would probably be very friendly and eager to make new friends in Riverdale. He might be a bit confused by some of the high - school drama but would try to stay positive. He could bond with Archie over their love for adventure and helping others. Betty would likely be intrigued by Naruto's unique abilities and his different way of looking at things. Jughead might be a bit more skeptical at first but would eventually come around as he sees Naruto's good heart.
