I'm not sure specifically as it depends on the fanfic. It could feature well - known characters from the Mass Effect games like Shepard, who might interact with the slip drive technology in unique ways.
There could be new characters created specifically for the fanfic. These characters might be scientists or engineers who are trying to understand or improve the slip drive. They could be from any of the races in the Mass Effect universe, such as the Asari or the Turian. Their personal stories and goals would then be intertwined with the development and use of the slip drive.
One interesting concept could be the unique ways the slip drive is utilized in the fanfic. Maybe it's used for faster-than - normal travel to unexplored regions in the Mass Effect universe.
In the 'Mass Effect Original Story', Commander Shepard is the protagonist. But the story is also populated with a host of other interesting characters. There's Urdnot Wrex, a Krogan who has his own agenda but also becomes an ally. Miranda Lawson is a human biotic who is part of Shepard's team in some parts of the story. Jacob Taylor is another human character who adds to the team's diversity. Each of these characters has their own backstory, personality, and role to play in the overall narrative of Shepard's quest to stop the Reapers and save the galaxy.
Some of the main characters might be Shepard, as he is a central figure in the Mass Effect series. There could also be other important characters like Liara T'Soni or Garrus Vakarian, who are well - known and beloved in the Mass Effect lore and are likely to be featured in the graphic novel to some extent.
There might be a human scientist who is at the forefront of some revolutionary discovery. This character could be trying to unlock the secrets of an ancient alien technology that has the potential to change the course of humanity's future in the fanfiction.
I'm not entirely sure as I haven't read it fully, but it probably features Ryder, the main protagonist from the Mass Effect Andromeda game. They are likely central to the stories in the graphic novel as they are in the game.
It could be a mix of characters from both universes. There might be classic WW2 soldiers like Patton or Eisenhower, but with a Mass Effect twist. Maybe they have some kind of exposure to Mass Effect technology that gives them special abilities. Also, there could be Mass Effect characters like Shepard who are somehow transported to the WW2 era.
Obviously, Tevos is a main character. She's a significant figure in the Asari government. And then there are the OCs (original characters). These can be a wide variety of beings. It could be a human soldier who gets involved in Asari politics because of some incident related to Tevos. Or an alien scientist who teams up with Tevos to study an ancient Prothean relic. Each OC brings their own backstory, skills, and motives to the story.
I'm not entirely sure but it could feature some of the well - known characters from the Mass Effect series like Shepard.
A turian officer could be a great main character. They are known for their military discipline and honor, and seeing the war from their perspective would be interesting.
Liara is frequently featured in 'mass effect crossover fanfic'. Her knowledge of Prothean technology and her overall intelligence can be used in various crossovers. For example, in a cross - over with a more magical - based science - fiction universe, her understanding of ancient technology could be a bridge between the two worlds. Another popular character is Tali. Her skills as an engineer and her relationship with Shepard make her a natural choice for fanfic authors to include in crossovers.
