Sasuke could be a very interesting character in this crossover. He has his own dark and brooding nature. He might be more interested in the stronger and rarer Pokemon. His sharingan could give him an edge in understanding Pokemon's abilities and behaviors. He could also train Pokemon in a more intense and strict way compared to other trainers.
Goku from Dragon Ball (just kidding, not part of Naruto or Pokemon but for a fun comparison). Seriously, Kakashi would be great. His laid - back but highly skilled nature could make for some interesting interactions. He might have a team of unique and rare Pokemon that he's collected over the years. And his experience as a ninja teacher could also come in handy when training Pokemon. He could teach them ninja - like stealth and combat maneuvers.
Naruto would be the most interesting. His energetic and head - strong personality would make for great interactions with the Pokemon world. He could be constantly amazed by the different Pokemon and their abilities, yet still use his ninja skills and quick thinking to adapt. His ability to make friends easily would also mean he'd quickly bond with his Pokemon and other trainers.
Definitely Naruto himself. He has such a vibrant and unique personality. His never - give - up attitude would make him an amazing Pokemon trainer. He would approach Pokemon battles with the same tenacity he has in ninja battles. Also, his ability to form strong bonds, like he did with his friends in the Leaf Village, would translate well into bonding with his Pokemon.
Naruto and Pikachu would be an interesting pairing. Naruto's high energy and Pikachu's feisty nature would make for some great adventures. They could both learn from each other's determination and loyalty to their friends. Another good pairing could be Sasuke and Charizard. Sasuke's brooding and powerful nature would match well with Charizard's strength and proud demeanor.
I think Pikachu and Graystripe would make a fun pair. Pikachu's cute and energetic nature could contrast with Graystripe's more laid - back but still adventurous self. Also, Brock and Tallstar could be an interesting duo. Brock's knowledge of healing and Tallstar's wisdom could lead to some great conversations and collaborative efforts in the crossover story. And let's not forget about Team Rocket's Jessie and a sneaky rogue Warrior. They could plot together or end up competing in their own devious ways.
I think Pikachu and Shippo would make an adorable pairing. They are both small and cute, but also have their own unique powers. Pikachu's electricity and Shippo's fox magic could be combined in interesting ways during battles. Also, Brock and Miroku would be an interesting pair. Brock is always chasing after girls, and Miroku has his own, well, wandering hand problem. They could bond over their, um, interesting relationship with the opposite sex while also sharing their knowledge of healing (Brock with Pokemon and Miroku with his spiritual healing).
I think Thor and Zapdos would be an amazing pairing. They both have control over electricity in a way. Thor could ride Zapdos into battle, and they could combine their lightning attacks for a devastating blow. Also, Black Widow and Umbreon. Black Widow is a stealthy assassin, and Umbreon is a nocturnal Pokemon that can use dark - type moves and has good stealth capabilities. They could work together on covert missions, with Umbreon using its moves to create distractions while Black Widow takes out enemies.
Mario and Pikachu would be an interesting pairing. Mario's brave and adventurous nature combined with Pikachu's electric powers and cute yet determined personality could lead to some great adventures. They could work together to overcome obstacles like Mario using Pikachu's electricity to power up certain mechanisms in the Mushroom Kingdom.
Definitely Gaara. His ability to control sand is unique. In the Borderlands 2 setting, he could use his sand to protect his teammates from the various attacks, like from the psychos or the Loader Bots. His transformation into Shukaku could also be a very powerful and visually striking element in the crossover.
I think Gintoki would be the most interesting. His laid - back and cynical nature would contrast so much with the more idealistic Naruto. He would constantly be making sarcastic remarks about Naruto's ninja -isms and the whole concept of being a hero. But at the same time, he would also be secretly impressed by Naruto's unwavering determination. And seeing Gintoki try to use Naruto's ninja tools or techniques in his own wacky way would be really entertaining.
