Who would be the most interesting characters to pair in a Mass Effect Destiny crossover fanfiction?

One idea could be to have the Guardians from Destiny encounter the Normandy crew in Mass Effect. They could team up to fight a common enemy like a new, powerful alien race that has the technology to disrupt both the Traveler's Light in Destiny and the Mass Relay network in Mass Effect.

Another plot could involve a shared enemy that exists in both universes. The combined forces of Mass Effect races and Destiny Guardians have to figure out how to defeat this enemy. They would need to overcome their differences in culture and combat styles to be successful.

The writer could also start by focusing on a character from one universe who stumbles upon an object or a phenomenon related to the other universe. For example, a Guardian could find a Prothean artifact, which then leads them to discover more about the Mass Effect universe and eventually meet its characters. This way, the story can gradually unfold as the character's curiosity drives the exploration of the crossover.

A great Mass Effect crossover fanfiction idea could be a crossover with the Stargate universe. The Mass Effect races could discover the Stargate network and start exploring other galaxies through it. There could be conflicts and alliances with the various races in the Stargate universe. Also, a crossover with the Dragon Age series might be interesting. The mages and warriors of Dragon Age could interact with the biotics and soldiers of Mass Effect. They could learn from each other's magic and technology, and perhaps even fight together against a dark force that threatens both universes.

Shepard could be an interesting character to be part of a harem. Their leadership skills and heroic status would make for an interesting dynamic within a harem. Liara T'Soni is also a great candidate. Her knowledge as an asari and her relationship with Shepard in the original games could be expanded upon in a harem scenario. Garrus Vakarian too, with his loyalty and combat skills, could add a different dimension to the harem.

Pairing the Witch Queen from Destiny with Darth Vader would be an intense combination in a 'Destiny Star Wars crossover fanfiction'. The Witch Queen's powerful magic and her manipulative nature against Darth Vader's dark side powers and his loyalty to the Emperor. It would be a battle of wills and a struggle for power as they either try to outwit each other or find some common ground.

One interesting concept could be the crossover of different species from the Mass Effect universe in unexpected ways. For example, seeing Asari and Krogan working together in a completely new scenario that was not in the original games. Another could be the melding of Andromeda's technology with that of the Milky Way's in unique and creative ways, like a new type of weapon or ship design.

One idea could be the Pilots from Titanfall teaming up with the Normandy crew in Mass Effect. They could share their combat skills and technology. For example, the Pilots' parkour abilities might amaze the Mass Effect characters, and in return, the advanced biotics and tech of the Mass Effect universe could be useful for the Titanfall side.

One interesting concept could be the combination of the advanced technology from Crysis with the diverse alien species in Mass Effect. For example, the Nanosuit's capabilities like enhanced strength, speed, and cloaking could be integrated into a Mass Effect - style story. Maybe a human character wearing a Nanosuit gets involved in a diplomatic mission among the various alien races in the Mass Effect universe, creating unique situations where they have to use the suit's features to survive and influence the outcome.

The idea of chakra being used in the Mass Effect universe is also very cool. Since the Mass Effect world has its own forms of energy, seeing how chakra could interact with biotics or other forms of technology would be exciting. It could open up new ways of powering devices or enhancing biotic abilities.
