Malcolm Merlyn is another good character for an Arrow fanfic. His motives are often ambiguous. He could be written as a more sympathetic character in a fanfic, or his past and his relationship with Thea could be delved into more deeply, adding new layers to his already complex character.
Oliver Queen is an obvious choice. He has such a complex backstory with his time on the island, his return to Starling City, and his evolution into the Green Arrow. His relationships with other characters like Diggle, Felicity, and Laurel also offer a lot of material for a fanfic.
Felicity Smoak is also great. Her character provides a contrast to Oliver's more brooding nature. She's smart, witty, and her growth from a tech - support girl to an integral part of Team Arrow can be explored in many interesting ways in a fanfic.
Xander is a great character to feature. He's always full of energy and getting into fun adventures, which can make for an exciting story. Also, Emma, as she's often the voice of reason among the campers and can bring a sense of stability to the plot. And Lou, the counselor, is another good choice as she has to deal with all the camper's antics.
Erina could also be great. Her refined palate and high standards add a layer of complexity. A fanfic could explore her journey of trying new and unorthodox cooking styles while still maintaining her elegance and grace in the kitchen.
Syd is a character that can bring some humor to a fanfic. His interactions with Kat and his role in the story can be expanded. He could be involved in some comical misadventures while also being an important part of the group.
Kakashi would be an interesting character to include. His intelligence and combat experience could make for an exciting story as he figures out how to best utilize the shield in different scenarios.
Naruto himself is a great choice. His goofy and determined nature can lead to many comical situations. Shikamaru too, with his lazy yet intelligent attitude. His sarcastic remarks can add humor. And Lee, his over - the - top enthusiasm for training and his unique fighting style can be a source of comedy.
I think Megumi would be a wonderful character to feature. She has a lot of growth potential in a fanfic. Starting from her insecurities and seeing her develop into a more confident cook. Also, Kuga can bring in an element of exotic and bold cooking styles. And don't forget about Akira, who has his own brand of precision cooking. Including these characters can add different flavors to the fanfic, both literally and figuratively.
In my opinion, the best characters to feature in a Naruto Pokemon fanfic would be Naruto, Sakura, and Shikamaru. Naruto is obvious as he's the main character and his never - give - up attitude can inspire his Pokemon. Sakura has the medical skills which could be useful in treating injured Pokemon. Shikamaru is super intelligent and could come up with great strategies for Pokemon battles. They could all have different types of Pokemon that complement their personalities, like Naruto with a Fire - type Pokemon, Sakura with a Grass - type for her healing abilities, and Shikamaru with a Psychic - type to match his intelligence.
Ruby is a great choice. Her innocent and energetic personality can be really interesting when combined with an animal form or when interacting with animals. Blake would also be good as she has a connection to the Faunus, which are part - animal. You can explore her dual nature further in an animal - themed fanfic. Weiss could be portrayed as having a special bond with a magical ice - based animal, like a snow leopard.
Sasuke is an obvious choice. He's already associated with swords like the Kusanagi. A fanfic could explore his further development with the sword, perhaps unlocking new abilities or techniques.
Oz Vessalius is a great character to feature. His complex backstory, including his connection to the Abyss, gives a lot of room for exploration in a fanfic. Another good one is Alice. Her brash and often unpredictable nature can add a lot of interesting twists to a story. Also, Gilbert is a character full of loyalty and internal conflict, which can be used to create engaging storylines.
