If we consider a crossover with Naruto, Naruto Uzumaki himself would be a good choice. Naruto's never - give - up attitude and his own powerful ninja abilities could interact well with Mob. They could bond over their shared experiences of being outsiders in some ways. Naruto could learn about the different kind of power Mob has, and Mob could be inspired by Naruto's determination to protect his friends and village.
In a crossover with Attack on Titan, Levi Ackerman could be a great character to include. Levi's no - nonsense attitude and his exceptional combat skills could contrast with Mob's more passive and emotional nature. They could be forced to work together to fight off a common enemy, like a new type of titan that has psychic abilities itself. It would be interesting to see how Levi's physical combat skills and Mob's psychic powers could complement each other.
Teruki Hanazawa from Mob Psycho 100 could be really interesting in a crossover. He might initially see Saitama as a rival, thinking that his strength is just another form of power that he can compete with. But as he gets to know Saitama better, he realizes that Saitama's power is on a whole different level. Saitama, in turn, would probably just be like 'oh, another guy with powers' and not be too fazed. And when it comes to characters like Genos from One Punch Man, he might be very curious about Mob's psychic abilities and try to analyze them scientifically.
John McClane from Die Hard would be a great addition. He has a similar tough - guy attitude and is good at handling high - pressure situations in urban environments. Another good character could be Ellen Ripley from Alien. Her experience with alien threats would contrast well with Rambo's combat skills. Also, Indiana Jones would be a perfect fit. His knowledge of archaeology and adventure - seeking nature combined with Rambo's combat expertise could lead to some exciting storylines.
Storm from the X - Men would be a great addition. She has control over the weather, which could create some really interesting scenarios when combined with Wolverine's combat skills. For example, she could create a lightning storm while Wolverine battles enemies in the rain, using the flashes of lightning to his advantage.
In a crossover with Hannah Montana, obviously Miley Stewart as Hannah Montana herself. She could be in Seattle for a secret concert and needs iCarly's help to promote it without revealing her identity. It would be fun to see Sam trying to keep Hannah's secret while also being her usual wild self around her.
In a crossover with the Lord of the Rings, Aragorn could be an interesting choice. He could bring his leadership skills and combat expertise to Los Santos. The GTA 5 characters might initially be skeptical of his noble ways, but they could learn from him. He could also help them fight against a new evil force that has emerged in the city, perhaps an ancient and powerful gang with dark magic - like abilities.
If it was a crossover with The Evil Within, Sebastian Castellanos would be a great character to include. His detective skills and his ability to handle the nightmarish creatures in his own game could be useful in the Outlast 2 world. He could team up with the Outlast 2 character to solve the mysteries behind the horror. Also, Pyramid Head from Silent Hill could be a terrifying addition. His presence alone would heighten the sense of dread in the Outlast 2 crossover story.
Definitely Goku. Their previous encounters in the Dragon Ball series make it a natural choice. Their power levels and different fighting styles would create great tension and action in the story.
Well, if you're doing a crossover with '101 Dalmatians', Cruella de Vil could be an interesting addition. She might see the Aristocats as a new target for her fur coats, creating a whole new conflict for the cats to face. And the Dalmatians could be allies of the Aristocats, helping them outwit Cruella.
A crossover with Jujutsu Kaisen would also be cool. Mob and Yuji could team up against curses. Since Mob has such strong psychic powers and Yuji has his physical strength and Sukuna's power, they could combine their abilities in unique ways. For example, Mob could use his psychic powers to hold a curse in place while Yuji delivers a powerful physical blow.
Goku from Dragon Ball is a must - include. He's the iconic Super Saiyan. And then maybe Thor from the Marvel Universe. Their different powers would make for an interesting dynamic. Also, Link from The Legend of Zelda could be a great addition, as he has his own set of unique abilities.
