A possible plot is a group of Skyrim adventurers stumbling upon a Halo ring. They have to navigate the strange and often hostile environment, facing off against the Flood and the Covenant. The mages in the group could try to use their magic against the alien threats, while the warriors use their swords and shields in combination with Halo weapons they find. It could be a story of how two very different universes collide and the characters adapt.
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.
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.
One idea could be that the Dragonborn from Skyrim somehow gets transported to the post - apocalyptic world of Fallout 4. Maybe they have to deal with the new threats like the raiders and mutants using their dragon - slaying skills. Another plot could involve the Sole Survivor from Fallout 4 finding a way into Skyrim and getting caught up in the civil war there, having to choose a side while also trying to find a way back home. Or perhaps a magical artifact from Skyrim ends up in Fallout 4 and causes all kinds of chaos as different factions fight over it.
One idea could be a character from Fallout finding themselves in Skyrim. Maybe they bring their advanced weaponry, like a laser pistol, into Skyrim's medieval - like world. This would cause quite a stir among the locals, who have never seen such technology. The character could then get involved in Skyrim's political intrigue, using their unique skills to help or hinder different factions. Another plot could involve a Skyrim mage traveling to the Fallout wasteland. They would be amazed by the strange, post - apocalyptic magic (technology) there and try to learn about it, while also using their own magic to survive against the mutated creatures.
One idea could be a Hobbit finding their way into Skyrim. Maybe they get mistaken for a child at first due to their small stature. They could bring their Hobbit - like skills of stealth and a love for food. For example, they might start a small cooking business in one of Skyrim's towns, using unique Hobbit recipes and ingredients they manage to find in Skyrim. This could attract all kinds of characters, from the local Nords to the wandering adventurers.
One idea could be that Percy Jackson finds himself magically transported to Skyrim. He could use his water - bending abilities in the frozen landscapes, perhaps to help deal with frost trolls by using water to freeze their legs or something. Another plot could involve Annabeth Chase coming to Skyrim and using her strategic mind to navigate the political intrigues of the different holds. And maybe a demigod from PJO teams up with a Dragonborn in Skyrim to fight a common enemy like an ancient evil that threatens both their worlds.
Well, perhaps Eragon's dragon, Saphira, is injured and they have to seek out the healing magic in Skyrim. Along the way, they meet the Dragonborn. The two dragon - related characters could either become friends or rivals. Eragon might be amazed at the variety of dragons in Skyrim, some of which are different from the ones he knows. And he could share his knowledge of dragon - riding with the Dragonborn.
One idea could be that the Dragonborn is somehow transported to the RWBY world. They could use their shouts to combat the Grimm. For example, 'Fus Ro Dah' could send Grimm flying back, and the local Huntsmen and Huntresses are both amazed and a bit wary of this new power.
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 a Spartan from Halo ending up on Pandora. Maybe they team up with the Na'vi to fight off a common enemy, like a new type of alien that's more powerful and dangerous than the Covenant or the RDA. The Spartan could introduce advanced human technology to the Na'vi, which would change their way of life in some aspects. For example, they could use some of the shielding technology to protect their homes. Another plot could involve the transfer of consciousness, like in Avatar, but with a Halo - related twist. Perhaps a character's mind is transferred into an enhanced alien body, similar to the Elites in Halo.
