The main characters would be Sly Cooper and a Pokemon like Eevee. Eevee has the ability to evolve into different forms, which could add an interesting element to the story. Sly Cooper could befriend Eevee and together they face various challenges. There might also be some secondary characters like Sly Cooper's gang members and other Pokemon trainers or Pokemon that they encounter during their adventures in the crossover world.
It could be Orochimaru. He's always interested in new powers and artifacts. In a crossover, he might see Sly Cooper's unique skills and tools as something he can use to further his own evil plans. He could also try to use Sly to steal secrets from other ninja villages. And of course, he would be a big threat to Naruto as well.
It could be really exciting. Imagine Sly Cooper trying to steal a rare Pokemon item from a powerful trainer. The sneaky skills of Sly Cooper would be put to the test against the trainer's Pokemon. Maybe he'd have to use his acrobatic moves to dodge attacks from Pokemon like Pikachu's thunderbolts or Charizard's fire blasts.
Ratchet would probably be a bit suspicious of Sly at first. He's used to dealing with more straightforward enemies. But Sly's charm might win him over. Sly, on the other hand, would be intrigued by Ratchet's high - tech gadgets and might try to steal one or two just for fun.
Obviously, Carmelita and Sly Cooper are the main characters. Carmelita is the inspector who is always trying to catch Sly. Sly is the master thief. Their interactions and Carmelita's reactions to Sly's actions are the focus.
The main characters are Sly Cooper, Bentley, and Murray.
Sly would probably be initially shocked. But then he'd be overjoyed. He'd start making plans to keep her and the baby safe. He might even consider retiring from his thieving ways to be a full - time family man.
In Miraculous Ladybug, Ladybug and Cat Noir are super popular for fanfiction. Their dynamic relationship, both as superhero partners and with the underlying love - square aspect, gives a lot of room for creativity. For Sly Cooper, Sly himself is a very popular character. His cool, suave thief persona makes him a great protagonist for all kinds of adventures in fanfiction.
Definitely Simba and Pikachu. Simba as the rightful king of the Pride Lands represents leadership and courage. Pikachu, being one of the most popular Pokemon, is full of energy and has a strong sense of loyalty. They could form an unlikely but strong friendship in the crossover.
One possible plot is that a dimensional rift opens up due to some experiment gone wrong in Ratchet's world. Sly Cooper and his team are sucked into it and land in Ratchet's universe. They have to figure out how to get back home while also helping Ratchet deal with a new threat that is attracted to the strange energy of the rift.
One possible plot could be that Sly Cooper is on a heist in a world that has some sort of connection to the Naruto universe. Maybe he's stealing a valuable scroll that contains a powerful jutsu. Naruto, being the curious and justice - loving ninja he is, mistakes Sly for a bad guy at first. But as they interact, they realize they can help each other. Sly can use his thieving skills to get some intel for Naruto about an enemy ninja group, and Naruto can protect Sly from the more dangerous ninja threats.
