Who could be the main characters in a Mass Effect XCOM crossover fanfiction?

Shepard from Mass Effect is a very likely character. Given their leadership skills and experience in dealing with various alien threats, they would be a natural fit in a crossover. They could potentially lead XCOM forces or at least be a key figure in coordinating between the two universes.

Definitely Commander Shepard from Mass Effect. He/She is the central character in Mass Effect and would be a natural fit to interact with XCOM forces. Also, XCOM's Central Officer or top - ranking soldiers could be prominent. They could be the ones making decisions on how to deal with Mass Effect threats or form alliances.

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.

Another aspect could be the exploration of the political and cultural differences between the two universes. XCOM is mainly focused on Earth defense, while Mass Effect has a complex galactic political system. A fanfiction could explore how the two groups interact when it comes to things like trade, alliances, and dealing with common threats. For instance, how would the XCOM Council (if there was one in the crossover) deal with the Citadel Council's decisions and vice versa?

One idea could be having the XCOM soldiers use their combat skills in the Mass Effect universe. Maybe they are sent to help fight against the Reapers. They could introduce their unique tactics and weaponry to the Mass Effect races.

Well, in 'xcom mass effect crossover fanfic', perhaps a cool concept is the interaction of the characters. Imagine Commander Shepard teaming up with XCOM operatives. They could share their combat strategies and knowledge. Also, the idea of using Mass Effect's biotics in XCOM missions or having XCOM's psi - ops in the Mass Effect universe could add a whole new layer of excitement to the story.

Shepard could be one of the main characters. Imagine Shepard having to deal with Venom's presence. Shepard's leadership skills would be put to the test as they try to figure out if Venom is a threat or an ally. Also, Garrus could be involved. His combat skills and loyalty to Shepard would make for some interesting interactions with Venom.

Master Chief from Halo is an obvious choice. His super - soldier skills and stoic nature would be really interesting to see in the Mass Effect universe. Another one could be Commander Shepard from Mass Effect. Putting Shepard in the middle of a Halo - style conflict would be exciting. And Cortana, the AI from Halo, could also play a major role. Her intelligence and relationship with Master Chief could be explored in new ways when combined with the Mass Effect elements.

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.
