The Odyssey Resurgence by fmfan1980 is a crossover between Stargate SG-1 and Independence Day: Resurgence; after the Odyssey has received the Asgard Core, the destruction of Orilla as the ship was entering hyperspace sends the Odyssey into a parallel universe, where they arrive just as Earth is under attack by the Harvesters. After helping the alternate Earth fight off the ship, the Odyssey sets out to both find a way home and help the alternate Earth deal with their own alien threats, leading to some interesting discoveries on both sides.
The Odyssey Resurgence contains examples of:
- Alien Non-Interference Clause: Landry uses the history of the Tollan as an example of why his Earth is reluctant to provide weapons technology to the other Earth, but assures Adams, Whitmore and Levinson that he will provide them with other examples of advanced technology, such as power generators.
- Big Damn Heroes:
- The Earth Space Defence has just witnessed the failure of their first two major attacks when the Odyssey shows up and drives the Harvesters back after inflicting severe damage.
- Later, the Odyssey arrives in time to save the alternate Thor from a Replicator attack, and it is suggested that the knowledge from the Asgard core and the Furling sphere will help the alternate Asgard solve their own degradation problem.
- Canon Welding: Analysis of the Asgard core reveals that the sphere that came to Earth is actually an example of Furling technology, and Daniel discovers records of what happened to the Harvesters in the Stargate universe.
- Doppelgänger Gets Same Sentiment: General Landry, SG-1 and the crew of the Odyssey are all grateful to meet the local version of Thor when they find themselves in a parallel universe after the destruction of Orilla, although Thor needs to see the Asgard cores holographic recreation of his other self to be assured that the Odyssey didnt just steal the technology from his counterparts.
- Expendable Alternate Universe: While the crew of the Odyssey acknowledge that this isnt their Earth, they immediately act to defend it from the Harvesters, and do their best to offer help without giving this version of humanity anything too advanced.
- Fantastic Racism: Discussed after the Odyssey allows some of the Earth Space Defence on board, as a few soldiers nearly shoot Teal'c and Vala just because they identify themselves as non-human. Landry makes it clear that the ESD will have to recognize that the galaxy is a lot bigger than 'human' and 'alien' if they're going to find allies against the Harvesters.
- Godzilla Threshold: SG-1 comes to appreciate how stretched the ESDs resources must be when he tells General Adams about the Replicators and Adams considers the possibility of turning the Replicators on the Harvesters to stop them, although he accepts Carter and Landrys argument that the Replicators are too dangerous to seriously consider that as an option.
- In Spite of a Nail: While there are obvious differences in the history of the two worlds, the Odyssey is able to detect the Antarctica Stargate in the same location where it was discovered in their universe, which helps to assure the crew that some of their advanced allies from their home universe may still exist here.
- Nightmare Fuel: Tealc and Valas tales of the Goauld inspire this among the members of Legacy Squadron, characters acknowledging how disturbing it must be to be trapped under the control of a Goauld.
- Reasonable Authority Figure: Despite the devastation caused by the Harvesters, the ESDs key leaders- including David Levinson, ex-President Thomas Whitmore, current President Elizabeth Lanford, and General Adams- all listen to and acknowledge the displaced General Landry's advice about finding alien allies in their universe. In return, when the alternate Thor comes to Earth to meet with Lanford and Whitmore to ask if either of them can speak for Earth when appealing to the Asgard for help, Thor accepts Lanford's explanation that Whitmore is the best qualified person Earth can spare for negotiations after the devastation caused by the latest Harvester attack and assures her that he will support Whitmore's appeal to the Asgard High Council.
- Remember the New Guy?: Analysis of the Asgard Core helps Daniel find out that, in their home universe, the Harvesters were destroyed by the Dakara superweapon, which was programmed specifically to target the Harvesters (its later purpose to restart life was only used later).
- Small Name, Big Ego: In a loose sense; the Secretary of Defence attempts to order the Odyssey to land and share all their technology with Earth, but Landry counters that the Odyssey is part of Homeworld Security rather than the Earth Space Defence and the Secretary has no authority to give him orders.
- Spared by the Adaptation: The first contact between the Odyssey and this Earth is to save President Elizabeth Lanford and her cabinet, and Whitmore is spared from having to make his Heroic Sacrifice.
