What could be an interesting plot for a 'halo forward unto dawn crossover fanfiction'?

Cortana and Chyler Silva would make for an exciting pair. Cortana is the intelligent AI from 'Halo', and Chyler Silva has her own set of skills in 'Forward Unto Dawn'. Cortana could help Silva with her technological challenges, and Silva could offer Cortana a different perspective on human nature and relationships.

Well, perhaps in the fanfiction, Lara Croft is exploring an uncharted planet when she stumbles upon a Halo ring. This attracts the attention of the Covenant, and Master Chief arrives to deal with the situation. At first, there's some tension between them as they come from different worlds and ways of doing things. But as they start to understand each other's motives and skills, they combine Lara's knowledge of ancient mysteries and Master Chief's combat expertise to fight the Covenant and figure out the secrets of the Halo ring.

One possible plot could be that the Master Chief is somehow transported to the Avengers' universe. He teams up with Iron Man to stop a new threat that combines Covenant and Hydra technology. Their combined skills in combat and technology would make for an exciting adventure.

One possible plot could be that Master Chief somehow gets transported to the Star Wars Rebels universe. He teams up with the rebels to fight against the Empire. His advanced armor and combat skills would be a great asset. Maybe he has to face off against Imperial Inquisitors and uses his Spartan training to outwit them.

One idea could be that the Master Chief somehow gets transported to Skyrim. He could use his advanced combat skills and high - tech weaponry in the medieval - like setting of Skyrim. For example, facing off against dragons with his energy sword, creating a really cool contrast between the high - tech and the fantasy elements.

Well, in this crossover, perhaps the Covenant from Halo decides to take advantage of the chaos in the Starship Troopers' world. The bugs become a new target for the Covenant's religious zeal. Meanwhile, the Starship Troopers' soldiers and the Halo UNSC forces have to figure out how to deal with this new threat. They might start by sharing intelligence about the Covenant and the bugs. Some Starship Troopers could be trained by the Spartans in more advanced combat techniques. And in the end, they all team up to stop the Covenant's plans and also push back the bug hordes.

One possible plot could be that Percy and his demigod friends are somehow transported to the Halo universe. They could team up with the Spartans to fight a common enemy, like a new kind of powerful monster that has emerged in the Halo world due to some strange rift between the two universes. Percy could use his water powers in unique ways, for example, to short - circuit some of the Covenant technology which might be vulnerable to water in this crossover scenario.

One idea could be that the Servants from Fate are transported to the Halo universe. For example, Saber could find herself in a battle against the Covenant. Her noble phantasm could be a powerful weapon against the alien foes. Another plot could involve Master - Spartan team - pairings. A Spartan could be paired with a mage to fight a common enemy that threatens both the Halo and Fate worlds.

One idea could be that the Master Chief is somehow transported to Skyrim. He might use his advanced combat skills and technology to deal with the dragons. For example, his energy shields could protect him from dragon fire. Another plot could involve the races in Skyrim getting access to Halo's weaponry and having to figure out how to use it. Maybe the Dwemer could reverse - engineer Covenant weapons.

Another plot could involve Noble 6 having their consciousness transferred into a Forerunner construct in a crossover. This would force them to navigate Forerunner technology and politics while still trying to uphold their UNSC values. They could form an unlikely alliance with a Forerunner AI to stop a rogue element within the Forerunner society.
