In this kind of fanfiction, characters like Erza Scarlet from 'Fairy Tail' could be potential members of the harem. She's a powerful and fearless female character. Also, Mikasa Ackerman from 'Attack on Titan' might fit in. Her protective nature could be an interesting contrast to Goku's more carefree attitude, creating a lot of interesting storylines within the harem.
Potential female characters could include Sakura from 'Naruto'. She has her own strength and growth arc, and her interactions with Goku could be fascinating. Additionally, Rias Gremory from 'High School DxD' would be an interesting addition. Her devilish charm and leadership qualities would make for an exciting part of the harem in relation to Goku.
Bulma could be one. She already has a long - standing relationship with Goku in the original series. Her intelligence and sass could add an interesting dynamic to the harem. Another could be Android 18. She's strong and independent, and her interactions with Goku could be really cool in a harem scenario.
In a crossover with Sailor Moon, Sailor Venus could be part of the harem. She is a strong fighter like Goku in her own way, and their different powers and personalities could create interesting dynamics.
Bulma could be one. She already has a long - standing relationship with Goku in the original series. Another could be Sailor Moon. Her strong sense of justice and powerful abilities would make for an interesting addition. Also, Mikasa from Attack on Titan with her combat skills and loyalty could be part of the harem.
Rukia could be one of the characters. Since she has a deep connection with Ichigo already in the original series, it would be easy to develop a more romantic aspect in the harem setting. Orihime is also a likely candidate, as she has strong feelings for Ichigo. And from other animes, a character like Saber from 'Fate/stay night' could be interesting. Her noble and powerful nature would contrast with Ichigo's more rough - around - the - edges personality.
Well, obviously Lucy from Fairy Tail would be a likely candidate. She already has a strong connection with Natsu in the original series. Then from the world of Bleach, Rukia could be an interesting addition. Her cool and collected nature would contrast with Natsu's hot - headedness, and her Soul Reaper powers would add an interesting dynamic to the harem. Also, from Attack on Titan, Mikasa could be in the harem. Her strong combat skills and protective nature towards Eren could translate into a similar protectiveness towards Natsu in the fanfiction.
Gwen could be one of the characters in the harem. She already has a close relationship with Ben in the original series. Another could be Kai Green. She's shown interest in Ben before and could easily be part of a harem in a fanfiction. Also, female aliens like Rook's sister (if she exists in the fanfic's version) could be part of it.
Bulma could be one of the characters in the harem. She has a long - standing relationship with Goku and her intelligence could complement Goku's power. Another could be Chi - Chi, his wife. Her fierce loyalty and determination would make her an interesting part of the harem.
Well, obviously Mary Jane Watson is a top choice. She has a long - standing relationship with Spider Man in the original comics. Then there's Gwen Stacy, who also has a significant connection to him. Felicia Hardy, also known as Black Cat, with her flirty and adventurous nature would be a great addition. And we can't forget about Silk, Cindy Moon, who has her own unique powers and could bring an interesting dynamic to the harem. There could also be characters from other universes like Spider - Gwen if we're talking about a crossover situation.
Lara Croft could be one. She's a strong and independent adventurer. Her skills in exploration and combat would make her an interesting addition. She could team up with Master Chief and there could be a mutual respect that might lead to more than just friendship.
Well, for the Danny Phantom side, Sam and Tucker could be involved. Sam might be jealous at first when other girls start showing interest in Danny. Tucker could be the one giving Danny advice on how to handle the harem situation. From other shows, if it's a crossover with a magical girl anime, characters like Sailor Moon could be part of the harem. Her kind and powerful nature would make an interesting dynamic with Danny. Another could be Kim Possible. She's a strong and capable girl who would likely be intrigued by Danny's powers and get involved in his adventures, and potentially develop feelings for him.
Definitely Hinata. She already has strong feelings for Naruto in the original Naruto series. Sakura could also be part of it as she has a long - standing relationship with Naruto. From other series, if we're doing a crossover, Erza from Fairy Tail could be an interesting addition. She's strong, independent, and would make for an interesting dynamic in a harem situation with Naruto. Also, Rukia from Bleach could be another. She has a cool and collected personality which would contrast with Naruto's more exuberant nature.
