I'm not aware of any particularly popular 'lucky star rule 63 yaoi fanfic' works. It's a rather niche combination, and while there may be some fanfics out there, they might not have gained widespread popularity.
Honestly, I haven't come across any well - known 'lucky star rule 63 yaoi fanfic' works. Fanfic popularity can be very scattered. For a work like this, it would need to appeal to fans of 'Lucky Star' who are also into rule 63 and yaoi. The fanfic world is vast, and while there could be some great works in this category, they might not have broken out into mainstream popularity within the larger fanfic community. It could be that these works are shared more privately among a close - knit group of fans with those specific interests.
Well, 'lucky star' is a popular anime with a certain set of characters and a particular world. 'Rule 63' implies that the genders of the characters are swapped in some way. And 'yaoi' focuses on male - on - male romantic or sexual relationships. So a 'lucky star rule 63 yaoi fanfic' might be a fan - written story that takes the characters from 'Lucky Star', changes their genders according to rule 63, and then creates a yaoi - style relationship among them. However, this is just speculation as there could be many different interpretations depending on the author's creativity.
I'm not aware of any specifically 'popular' ones. Since this is a very specific and niche type of fanfic, it may not have works that are widely known outside of the dedicated RWBY fanfic communities that are interested in this particular combination of concepts.
There may be some popular 'star fox yaoi fanfic' works among the fans who are into this genre. But it's not something that has widespread acclaim in the general public. Usually, on fanfic platforms, there are certain stories that gain a following within the community. These could be the ones that have really engaging storylines, well - developed characters based on the Star Fox universe, and good writing in terms of exploring the male - male relationships. But without doing in - depth research on specific Star Fox yaoi fanfic platforms, it's hard to name any particular popular ones.
I'm not sure which ones are the most popular specifically. There are so many fanfics out there. However, some might gain popularity within certain fan circles if they have really interesting takes on the gender - swapped characters and their relationships. It really depends on the creativity of the writer and how well they can capture the essence of the RWBY world while also exploring this unique combination of yaoi and rule 63.
There could be popular ones, but it's a bit hard to determine without doing in - depth research into the Star Fox fanfiction community. However, in general, the ones that tend to be popular often have really interesting takes on the gender - swapped characters. They might have engaging storylines that not only play with the gender swap but also add new elements to the Star Fox lore. For example, a story where a female version of Fox McCloud has a different approach to leading the team and dealing with the threats in the Lylat system.
One common theme could be friendship evolving into something more. Since 'Lucky Star' has a lot of character relationships, in yaoi fanfic, it might explore the deeper feelings between male characters that were initially just friends.
I'm not sure if there are widely known 'autistic yaoi fanfic' works in particular. Since it's a rather niche combination, it might be harder to find mainstream popularity. However, within certain fan communities that are interested in both yaoi and autism - related themes in fiction, there could be some well - liked works that are shared among members.

As of now, I haven't come across any well - known 'cell absorption yaoi fanfic' works. The yaoi genre has a wide variety of themes and plotlines, but this particular one seems very specialized. It could be that it's a relatively new or emerging concept within the fanfic world. There might be some small - scale popularity within certain groups of fans who are interested in more experimental or off - beat story ideas, but it's not likely to be on the list of the most popular yaoi fanfics overall.
I'm not sure which specific 'Lucky Star' yaoi fanfics are good. You can try searching on some popular fanfic platforms like Archive of Our Own (AO3). They usually have a wide range of fanfics and you can filter by the 'Lucky Star' tag and the 'yaoi' genre.
