One of the most interesting storylines could be the interaction between the different species in Mass Effect and those from Stargate. For example, how would the Asari react to the Goa'uld? The Asari are a long - lived, biotic - using species in Mass Effect, while the Goa'uld are parasitic snake - like beings in Stargate. Another cool idea is the technology exchange. The Mass Effect universe has advanced biotic and cybernetic technology, and Stargate has its own unique wormhole - based travel and Ancient technology. A fanfiction could explore how these technologies might be combined or used against each other. Also, the cultural clashes would be fascinating. The different races in Mass Effect have their own moral and ethical codes, and the same goes for the races in Stargate. How would they deal with each other's values?
Well, a really engaging plot could be about a joint mission. Say, a group of Mass Effect races (like the Turians and the Humans) team up with the Stargate SG - 1 team. Their goal could be to stop a powerful new enemy that threatens both universes. This enemy might be something that combines the worst aspects of the Reapers from Mass Effect and the Wraith from Stargate. The story could show how they overcome their differences in combat styles and beliefs to fight this common foe. For example, the Mass Effect races are used to fighting in space and on different planets within their own galaxy, while the Stargate teams are more focused on inter - galactic travel through the stargates. But together, they could form a unique and powerful fighting force.
One of the most interesting storylines could be a situation where the technology from Stargate SG1 somehow finds its way into the NCIS world. For example, a Goa'uld symbiote might be discovered during an NCIS investigation on a military base. The NCIS agents, being used to normal criminal investigations, would be completely out of their depth dealing with alien technology and the threat of a parasitic alien life form. This would force them to team up with the Stargate SG1 team who have the expertise in dealing with such threats.
One interesting plot twist could be the combination of Stargate's wormhole technology with Mass Effect's mass relays. Imagine if the two were somehow integrated, allowing for new travel routes across galaxies. Another could be characters from the two universes swapping abilities. For example, a Mass Effect character getting access to Stargate's Ancient technology and using it in unexpected ways.
One interesting plot idea could be the combination of the technology from Mass Effect and the world - building of Anthem. For example, Shepard could find himself in the world of Anthem and have to adapt to the javelin exosuits while also dealing with the local threats. Maybe the Reapers start to target the world of Anthem as well, and the two groups from different universes have to team up to fight this common enemy.
One idea could be Master Chief being thrown into the Mass Effect universe during a crucial moment in the fight against the Reapers. His combat skills and Spartan abilities would surely turn the tide in unexpected ways. For example, his mastery of close - quarters combat could be a game - changer in battles where the Mass Effect characters are more used to ranged combat with biotics and guns. Another plot idea could be about the technology exchange. The Covenant technology that Master Chief is familiar with and the advanced tech in the Mass Effect universe might create some really interesting scenarios. Maybe the UNSC and the Citadel Council could form an alliance based on shared technology interests.
The best Stargate and Mass Effect crossover fanfics are the ones that blend the lore seamlessly. In some, we see the Asari being intrigued by the Ancient technology from Stargate. They might try to study it, leading to interesting cultural exchanges. Some fanfics also play with the idea of the Mass Relay system and how it could interact with the stargate network. It's all about creativity and how well the author can mesh these two distinct universes together.
The Asari from Mass Effect would be intrigued by the Ancient technology in Stargate. Their natural curiosity and long lifespan would make them eager to study it. Meanwhile, the Goa'uld from Stargate might see the various species in Mass Effect as potential hosts or slaves, which would obviously lead to conflict. But the more moral characters from Stargate would oppose this and try to protect the Mass Effect races.
A really cool plot twist could be that the Protheans, who are an ancient and advanced race in the Mass Effect universe, had actually encountered Cthulhu Mythos entities in the past. This could explain some of the mysteries surrounding their downfall and the disappearance of their technology. Maybe they tried to harness the power of these otherworldly beings and it backfired, leading to their civilization's collapse. This revelation would not only change how we view the Protheans but also add a new element to the overall lore of the Mass Effect universe.
A common storyline is the clash of cultures. The military - oriented Stargate teams with their high - tech weapons and strategies meet the lone - wolf immortals of Highlander. There could be a situation where an immortal Highlander is mistaken for an enemy by the Stargate team. Or, the Stargate team might need the help of an immortal to defeat a powerful alien foe that is immune to their normal weapons. The immortals' ability to sense each other could also play an interesting role in a Stargate - Highlander crossover, like when they are on a planet full of hidden threats and the immortal's sense helps the team avoid danger.
A rather unexpected but potentially great pairing could be Ashley Williams and Vala Mal Doran. Ashley is a tough and no - nonsense soldier in Mass Effect, and Vala is a wily and resourceful adventurer in Stargate. They could get into all sorts of scrapes together and use their different skills to get out of them. On the other hand, Kaidan Alenko and Jonas Quinn could be paired. Kaidan has biotic powers in Mass Effect, and Jonas has his own unique abilities in Stargate. They could explore how their powers might interact or complement each other in different situations.
A great storyline might involve a fusion of the two worlds' mechanics. For example, the Velvet Room from Persona could have some connection to Joker's world. The Igor-like figure could offer Joker and his friends some new kind of power or knowledge that they use to combat a common foe. Or perhaps the Persona characters learn about Joker's Metaverse Navigator and try to replicate it in their world, which leads to all sorts of unforeseen consequences and adventures.
