I'm sorry, but I have no idea about the main characters in this fanfiction. However, in a crossover fanfiction, we usually expect to see a combination of important characters from both universes. So from KOTOR, it could be the Jedi and Sith characters that play significant roles. And for the 'kaidan effect' part, there might be some unique characters that are central to that concept, and they all come together to form the story's main cast.
Since I haven't read 'the kaidan effect a me kotor crossover fanfiction', I can't say for sure who the main characters are. But it's likely that there will be characters from both the 'kaidan effect' side and the KOTOR side. Maybe some well - known KOTOR characters like Revan or Bastila will be involved, and there could be new characters related to the 'kaidan effect' as well.
I'm not sure specifically as I haven't read it. But generally, a crossover fanfiction combines elements from two or more different fictional universes. So it might blend the concepts related to 'the kaidan effect' with the 'KOTOR' universe in some interesting ways, perhaps with new storylines, character interactions or power dynamics.
A good crossover should have a well - thought - out plot. It needs to blend the two universes in a way that makes sense. For example, how the different species and technologies interact. Maybe in the fanfiction, the Mass Effect races encounter the Force from Kotor 1 in an interesting way.
Another place could be FanFiction.net. There are many dedicated writers on this platform who might have created such crossovers. Browse through the science - fiction and Star Wars/Mass Effect sections. You might need to do some sifting, but you're likely to find some interesting reads.
Social media groups on platforms like Facebook or Discord dedicated to Mass Effect or Kotor fans could be a source. People in these groups might be writing their own crossovers or know where to find them. Additionally, Tumblr sometimes has fanfiction posts, especially if you search for the specific tags related to the crossover.
A good crossover combines the elements of both universes well. For example, it might blend the unique species from Mass Effect like Turians and Asari with the Force - using concepts from Kotor 1. The characters should be in - character. If Shepard from Mass Effect meets Revan from Kotor 1, their personalities and motives should be consistent with their original games.
Shepard from Mass Effect could be a main character. They could lead the XCOM forces in a joint mission against a common enemy. Their leadership skills would be very useful in coordinating the two very different groups.
An Asari scientist could be a main character. She might be intrigued by the mystery of the abandoned Earth. Her knowledge of biotics and different cultures in the Mass Effect universe could help her in deciphering the secrets of Earth. She could be the one to make the first contact with any remaining humans or discover important artifacts. Also, a Krogan mercenary could be a main character. His brute strength and combat skills would be useful in exploring the dangerous and desolate Earth. He might be in it for the loot or just the thrill of adventure.
Since it's based on Kotor 2, the Exile is probably a central character. There might also be characters like Kreia, who was an important figure in the game. Other Jedi or Sith characters could also be main characters in the graphic novel, depending on how the story is adapted. They would all contribute to the overall plot and the exploration of the themes of the Star Wars universe within the graphic novel.
Since we don't know the specific details of 'the human effect fanfiction', the main characters could be a group of humans with different personalities and motives. Maybe there's a leader - type character who is trying to guide the others in dealing with the 'human effect' in the story. There could also be a character who is initially unaware of the human effect but gradually becomes a central figure in understanding and dealing with it.
