Obviously, Gumball himself is a central character. He's the one around whom the harem concept revolves. Penny is often included as she has a pre - existing relationship with Gumball in the original show. Her sweet and sometimes shy nature can add an interesting dynamic to the harem situation.
Well, obviously Sasuke is a central character. Naruto often makes an appearance as Sasuke's friend or rival. Female characters like Sakura, Hinata, and Ino are common in the harem. Sakura is Sasuke's former teammate and has had long - standing feelings for him. Hinata is known for her gentle nature and could be an interesting addition to the harem. Ino is also a strong - willed character who could add drama to the harem - based story.
The main characters are Gumball, that blue cat - like creature with a big imagination, and Chichi. Chichi might bring a different kind of dynamic to the story. Maybe she's more level - headed compared to Gumball, which creates a great contrast in their interactions.
In some fanfictions, there could also be other characters from their respective universes that play important roles. For example, Gumball's family members might make an appearance and interact with Marshall, which could add more depth to the story and show different aspects of Gumball's life.
Well, clearly the main characters are Gumball and Richard. Gumball is the blue cat with a big personality, always getting into all kinds of crazy situations. Richard, on the other hand, is Gumball's father, a large and somewhat lazy pink rabbit. Their relationship as father and son is central to any Gumball x Richard fanfiction.
The main characters are Carrie and Gumball. Carrie brings an element of the supernatural to the story. She has a gentle nature despite being a ghost. Gumball is full of energy and ideas. In fanfiction, they often encounter other characters from the Elmore universe, but they are the central focus, with their relationship evolving in different and interesting ways depending on the plot of the fanfiction.
Starfire could also be part of it. Her bubbly and positive personality would contrast with some of the other characters. She might be the one who always tries to cheer up the group and is very affectionate towards Beast Boy.
Obviously Naruto and Sonic are common characters as it's in the title. There could also be female characters like Sakura from Naruto series and Amy Rose from Sonic series.
One popular theme is the comical misunderstandings that can occur in a harem situation with Gumball's zany world. For example, different characters might misinterpret Gumball's friendly gestures as romantic advances, leading to all sorts of chaotic and funny situations.
Sakura is often one of the common female characters. In the original Naruto series, she has a pre - existing relationship with Naruto, so it's easy to include her in a harem scenario.
Obviously, Gumball and Chichi are the main characters. Gumball, with his zany and adventurous nature, and Chichi with her own unique charm and personality.
