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.
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.
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.
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.
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.
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.
Zelda is also a very popular choice. Her powers and her role in the events of the Age of Calamity can be expanded upon in fanfic. Maybe she has a different way of using her powers or a new discovery about them.
Definitely Ash Ketchum. He is a central figure in the Pokémon world, and in rational fanfics, he could be portrayed as more strategic and less impulsive. Misty is also popular. Her skills as a water - type Pokémon trainer could be expanded upon, like her knowledge of underwater ecosystems. And Brock too. His role as a healer and caretaker of Pokémon could be given more emphasis in these fanfics.
Ash Ketchum is often a central character. His experience and knowledge from different Pokemon regions can be a great asset in a crossover setting. Then there's Pikachu, of course. It's so iconic that it's almost a must - have in any Pokemon - related fanfic. Another popular character could be Misty, especially when exploring water - type Pokemon - related crossovers.
