In a Crazy Jane fanfic, it would be cool to include Danny the Street. Danny is such a unique and friendly entity. The way Danny can transform and the positive energy it exudes could be a great contrast to Crazy Jane's often chaotic internal world. And since Danny is a place as well as a character, it could provide a really interesting and different setting for the fanfic.
Definitely Cliff Steele. His robotic nature and his own internal struggles could contrast well with Crazy Jane's multiple personalities. Another good one is Rita Farr. Her insecurities and her ability to change form could lead to some interesting interactions with Jane.
Well, including Chief could be a great choice. He has a long history with Crazy Jane and his knowledge and authority within the Doom Patrol could play a big role in the fanfic. Also, consider adding Negative Man. His dark and brooding nature could create some tense and interesting moments when paired with Crazy Jane's unpredictable personalities. You could explore how their powers and personalities either clash or complement each other.
Sonic himself is a must - include. His speed and adventurous spirit drive the story forward. Tails is also great as he can provide technical support and is Sonic's loyal friend. And Dr. Eggman, as the main antagonist, always adds conflict and excitement to the story.
Vegeta is a great choice. His rivalry with Goku adds a lot of drama and action to a fanfic. Also, Piccolo, as he has a long history with Goku and has been both an enemy and a friend. Another good character could be Gohan, Goku's son, as it can explore their father - son relationship further in the fanfic.
Another good character to include is Lex Luthor. He could be the mastermind behind a plot to drive a wedge between Batman and Wonder Woman. His devious mind and resources would make him a formidable antagonist, and his interactions with the two heroes would add a lot of drama to the story.
Optimus Prime is a great choice. His leadership and wisdom can add depth to the story, and his relationship with Bumblebee can be explored further. Also, Sam Witwicky, as he has a strong bond with Bumblebee in the movies. Their friendship can be a central part of the fanfic.
Definitely Naruto himself, as he is the main character of the original series. Sasuke is also a great choice as his complex relationship with Naruto can add a lot of drama. Kakashi is another good character to include. His wisdom and unique abilities can be very useful in the story. And Sakura, her growth as a ninja can be explored further in a fanfic.
Well, obviously Armikasa themselves are the main focus. But you could also include their friends. For example, their comrades who are with them in training or on missions. These characters can add more depth to the story by providing different perspectives and interactions.
Nami would be a great character to include as she has a deep - rooted history with Arlong. Their interactions can add a lot of drama and emotion to the story. Luffy is also a good choice as he is the main protagonist and his values of freedom and justice would contrast sharply with Arlong's tyranny.
Obviously, Willy Wonka himself is a must - include. He's the heart and soul of the factory. Charlie Bucket is also great as he represents the pure - hearted visitor. The Oompa - Loompas add a lot of fun and mystery with their strange songs and unique appearance. Veruca Salt can bring in some drama as she was the spoiled brat in the original story.
It would be cool to include some of the other Shichibukai in a fanfic with Boa Hancock. Maybe Doflamingo, and the fanfic could explore the power dynamics and political intrigue between them as two powerful figures in the pirate world. Their different personalities and goals would make for an interesting story.
Akeno Himejima could also be a great addition. Her dual nature of being sweet but also having a darker side would create an interesting dynamic with Harry. They could have some really engaging conversations about power and morality.
