Sometimes, even Uzumaki Kushina could be featured. She could be shown as having some sort of connection to a special gaming realm or perhaps being a powerful gamer in her own right in the fanfiction, using her Uzumaki strength and wits.
Well, obviously Yamcha himself is the central character. But other characters from the Dragon Ball universe might also be included. For example, Bulma could be a supporting character, perhaps helping Yamcha with some high - tech gaming gear she invents.
Lex Luthor is another main character you'll see. His intelligence and his complex personality make for great material in gamer fanfiction. He might be the creator of a dangerous game or a player who will stop at nothing to win, which can lead to some intense plotlines involving the other Smallville characters.
Obviously, Buffy herself is a main character. She's usually at the center of the action, using her slayer skills in the game - inspired scenarios. Spike is also a common character. His complex relationship with Buffy often gets explored further in these fanfictions, especially in the context of a game world. Willow is another one, with her magic abilities being a key element in many of the stories.
Often, the gamer character themselves is a main focus. They bring their own set of skills and personality into the DC world.
Obviously, Naruto himself is often a main character. His natural talent and determination in the original series can be translated into the 'genius gamer' aspect. Sasuke might also be a key figure, as his rivalry with Naruto can be reimagined in the context of the gaming elements. Sakura could be there too, perhaps using her medical skills in a new way within the gaming - influenced story.
Hestia is also frequently seen. Her relationship with Bell can be explored further in the context of the 'gamer' fanfiction. Maybe she has some special powers or knowledge related to the 'gamer' elements, like being able to access a hidden 'goddess' shop where she can buy rare items for Bell at a discounted price.
Seto Kaiba is also a common feature. His drive for power and his rivalry with Yugi are great fodder for fanfiction. Fanfics might show his more vulnerable side or explore his relationship with his brother Mokuba in different scenarios.
Since it's a fanfiction about Naruko Uzumaki, she's likely one of the main characters. There may also be other Naruto - related characters like Sasuke, Sakura, or Kakashi who could be involved. They might interact with Naruko in the context of her 'gamer' abilities.
Isaac Clarke is surely one of the most popular. He is the main protagonist in the original Dead Space game, so in fanfiction, he often takes center stage, whether it's in new adventures or different takes on his existing story.
Illidan Stormrage is another fan - favorite. His quest for power and his role as a somewhat anti - hero give a lot of room for creative interpretations. Fanfic might explore his motives more deeply or create alternate scenarios where he takes different paths in his pursuit of power.
