One interesting Naruto and Captain Price fanfiction could be where they are in a crossover universe and have to team up to fight a common enemy. For example, a powerful demon or an evil organization that threatens both their worlds. In such a story, Naruto's ninja skills and Captain Price's military tactics would make for an exciting combination.
One great 'Naruto Captain Commander' fanfiction is 'The Captain's Path in Naruto'. It explores an alternate storyline where a character takes on the role of captain commander in the Naruto universe. The character development is really interesting as they face unique challenges.
The 'power - up' trope is also popular. For instance, Naruto could gain some knowledge from Captain Price's military strategies and use it to enhance his ninja skills, or Captain Price could get some sort of power - up from Naruto's world, like being able to use a bit of chakra for his own advantage in combat.
Another place to check is FanFiction.net. It has been around for a long time and has a lot of different fanfictions, including ones related to Captain Price. You might have to do a bit more digging through the search results, but you can often find some hidden gems.
One interesting Captain Price fanfiction could be about his early days in the military. It might explore how he trained, the challenges he faced, and the friendships he made. For example, a story could detail his first mission and how he overcame his nerves and inexperience to succeed.
One great RWBY and Captain Marvel fanfiction is 'A Meeting of Heroes'. In this story, the characters from RWBY's Remnant world somehow cross paths with Captain Marvel. It has really exciting action scenes where Ruby's scythe skills are combined with Captain Marvel's photon blasts. The story does a good job of balancing the different power levels and personalities of the characters.
I really like 'The Hidden Power within Naruto' fanfiction. In this story, Naruto discovers a new power that is not related to the Nine - Tails. It's a power that has been hidden in his family for generations. It makes for a really interesting read as he tries to master this power while still dealing with his normal ninja duties. There's also 'Naruto and the Lost Art' which is about Naruto finding and reviving an ancient ninja art.
One great Naruto and Captain Marvel fanfiction could be a crossover where they team up to fight a common enemy. Maybe a powerful alien that has invaded both the Naruto universe and the world Captain Marvel protects. In such a story, Naruto's ninja skills combined with Captain Marvel's superhuman abilities would make for an exciting adventure.
I really like 'Anbu Captain's Redemption'. In this fanfic, the Anbu captain has a dark past that he's trying to overcome. It's a great exploration of the character's psyche. The author does a wonderful job of integrating elements from the Naruto universe, like the use of jutsu and the relationships between different ninja clans. It also has some great fight scenes that keep you on the edge of your seat.
First, you need to study the characters well. Know Naruto's growth, his values, and his abilities. For Captain Marvel, understand her origin, powers, and personality. Then, create a plot that makes sense for both universes to collide. For example, a rift in dimensions could bring them together. Keep the dialogue true to their characters.
One great fanfiction is 'Allies in the Cosmos'. It beautifully weaves together the storylines of Captain America and Captain Marvel. In this fic, they team up to face a new alien threat that neither could handle alone. The writer does an excellent job of capturing their unique personalities and how they complement each other in battle.
