Well, one aspect could be the unique relationship dynamic that can be explored in such a fanfiction. It might involve Wheatley's bumbling yet endearing nature interacting with Chell's more stoic and determined personality. This can lead to some really interesting character development and plot twists within the fan - created story.
One common theme is self - discovery. Since Wheatley is now human, he has to figure out who he is and what he wants in this new form. Another theme is relationships. He has to interact with other humans and characters in new ways, which often leads to exploring themes of friendship and even romance sometimes.
The main characters are Wheatley and Chell. Wheatley is often portrayed as a bumbling but well - intentioned character, with his unique personality quirks. Chell, on the other hand, is known for her tenacity and determination. In the fanfiction, their human forms add a new dimension to their relationship and the stories that can be told about them.
The contrast between the two characters makes it interesting. Chell is a silent but strong protagonist, while Wheatley is a talkative and often clumsy character. Their interactions can be full of humor and unexpected moments.
A possible plot could also be a time - travel - like scenario within the fanfiction. Wheatley and Chell find themselves sent back to an earlier era of the Aperture Science facility. They have to figure out how to get back to their own time while also dealing with the different technology and perhaps even different versions of the characters they knew.
One popular theme is redemption. Wheatley, after all his misdeeds in the game, can be the focus of stories where he tries to make up for what he's done. Another is friendship, perhaps forming an unlikely bond with a human character. And exploration of his new human form and how he copes with it is also common.
One great human Wheatley fanfiction is 'The Adventures of Human Wheatley'. It explores Wheatley's new experiences as a human in a really fun and creative way. The character interactions are well - written and it keeps you engaged throughout.
Chell is often a common supporting character. Since she had a lot of interactions with Wheatley in the game, it makes sense for her to be in the fanfictions. Another could be Cave Johnson, who might offer some sort of guidance or be a source of conflict for Wheatley in his human form. And GLaDOS can also be a supporting character, perhaps still having some sort of rivalry with Wheatley even when he's human.
Wheatley is very significant in the 'Portal 2' Wheatley x Chell fanfic. He serves as a source of both humor and conflict. His bumbling nature at the beginning makes for some funny moments, especially when contrasted with Chell's more serious and determined personality. Later, when he becomes a villain of sorts, he drives the plot forward by creating obstacles for Chell. His character development, from a seemingly harmless sidekick to a powerful antagonist, is a major factor in the fanfic's overall narrative arc.
Romance is a very prominent theme. Given the unique relationship between Wheatley and Chell in the game, many fanfictions explore the romantic aspect of their relationship. This could range from a slow - burn romance where they gradually realize their feelings for each other, to more immediate and passionate love stories. Writers often play with their personalities, Wheatley's clumsy but endearing nature and Chell's silent determination, to create interesting romantic dynamics.
