In a fanfiction, Jaina Proudmoore could use her magic to study the energy shields of the Spartans. She might try to adapt that technology for use in Azeroth, perhaps creating new spells or enchantments. Meanwhile, the Spartans could learn from the mages about different forms of magic and how to use them in combat situations.
In a crossover, the Elites from Halo might interact with the Vulcans from Star Trek. The Elites' honor - based culture could be compared to the Vulcans' logic - based society. They could start off as adversaries, perhaps misunderstanding each other's motives, but then gradually come to respect one another as they learn more about their respective cultures and values.
The characters could interact through a portal that links their two worlds. For example, Master Chief could end up in Berk and be initially seen as a strange and powerful warrior by the Vikings. Hiccup, being the curious and open - minded character he is, would be the first to approach the Chief and try to communicate. They could then start to exchange ideas about their respective worlds and threats they face.
They could interact through combat. For example, the Spartans might fight alongside the SG teams against a common foe like the Covenant or a powerful Goa'uld army. The Spartans' combat skills and advanced armor would be a great asset in the Stargate universe battles.
The characters could start off as enemies. For example, the Covenant leaders might view the Star Trek captains as heretics. But as the story progresses, they could find common ground in the face of a greater threat like the Borg or the Flood.
If we consider the abilities of Servants in Fate and Spartans in Halo, it's really interesting. Servants have magical powers like Gilgamesh's Gate of Babylon which can summon countless weapons. Spartans, on the other hand, have their advanced combat training and high - tech armor. In a crossover, a Servant's magic might be able to disrupt a Spartan's high - tech equipment. For example, a lightning - based magic attack could short - circuit some of the Spartan's systems.
Perhaps a group of Azeroth's heroes, like the Night Elves or the Dwarves, stumble upon a Halo ring. They have to figure out the technology there while also facing threats from the Covenant. The mages could try to understand the Forerunner magic-like technology, and the warriors would engage in combat with the alien foes.
Well, the characters from Familiar of Zero are often from a medieval - like magical world. When they interact with the characters from Halo, which is a high - tech sci - fi universe, there can be a lot of culture shock. For instance, Saito from Familiar of Zero might be completely baffled by the advanced weaponry of the Halo characters at first. But then he could start to learn and adapt.
The characters could interact in various ways. For example, Percy could teach some of the Undertale characters about the surface world and how different it is from their underground home. Meanwhile, characters like Toriel might offer Percy and his friends some motherly advice and shelter, just like she does for Frisk in Undertale.
The characters could interact through magic exchanges. For example, Hermione could be fascinated by the magic of the ponies, which is so different from the wizarding magic she knows. She might try to study it and figure out how it works. In return, Twilight Sparkle could be interested in the books Hermione reads and learn about wizarding knowledge.
The characters could interact in various ways. For example, Merlin could meet Hermione. Hermione, being very interested in magic knowledge, would be fascinated by Merlin's different approach to magic. She might ask him a million questions about his spells and how he learned magic in his time.
