Solaire from Dark Souls and the Hunter from Bloodborne could make an interesting pair. Solaire is known for his sunny disposition and quest for his own sun, while the Hunter is all about the hunt in the dark and gothic world of Bloodborne. Their different outlooks and skills could lead to some great character development as they face challenges together.
Artorias from Dark Souls and Gehrman from Bloodborne. Artorias is a valiant knight, while Gehrman is the first hunter. Artorias' sense of honor and his battle skills could contrast with Gehrman's more worldly and perhaps more jaded view. They could team up against a common enemy that threatens both their worlds, and in the process, their different fighting styles and ways of thinking could create an engaging dynamic.
The Nameless King from Dark Souls and Lady Maria from Bloodborne. The Nameless King has his connection to dragons and his complex backstory in Dark Souls. Lady Maria is a skilled hunter with her own secrets in Bloodborne. Their encounter could be full of tension, as they both have strong wills and unique powers. They might initially be at odds due to their different worlds' values but could learn from each other.
One interesting concept could be the merging of the unique combat mechanics. For example, Dark Souls' methodical and strategic combat combined with Bloodborne's faster, more aggressive style. Maybe in the fanfiction, a character from Dark Souls has to adapt to the more blood - thirsty and fast - paced battles of Bloodborne's world.
I think Makoto Niijima from Persona 5 and Rin Tohsaka from Fate Stay Night would be a great pairing. Makoto is a strong - willed student council president, and Rin is a powerful mage. Their meeting could result in some intense discussions about leadership, power, and the use of their respective abilities. Plus, they both have a no - nonsense attitude which could lead to some interesting clashes and cooperation.
I think Ruby and the Chosen Undead would be a great pairing. Ruby is young and full of energy and idealism, while the Chosen Undead has seen so much and is a battle - hardened veteran. Their interactions could be really interesting as Ruby learns about the harsh reality of the Dark Souls world from the Chosen Undead.
Ladybug would be very interesting. Her positive and creative approach in Miraculous Ladybug would contrast greatly with the dark and gloomy world of Dark Souls. She could bring a new perspective to the problems and challenges in the Dark Souls world. Her ability to think on her feet and come up with solutions using her Lucky Charm would be fascinating to explore in a world full of death and despair.
Gascoigne from Bloodborne and Jon Snow would make for an interesting duo. Gascoigne is a fierce hunter, and Jon Snow is a great warrior. They could fight side by side against the White Walkers. Gascoigne's experience in hunting monstrous creatures could be invaluable in the fight against the undead, and Jon Snow's leadership skills could help in coordinating their efforts.
The Doom Slayer and Ruby. Ruby is young and full of hope, always looking for adventure. The Doom Slayer is a stoic, battle - hardened warrior. Their interaction would be really interesting. Ruby could be in awe of his strength and weapons, and the Doom Slayer might see a bit of his own unwavering will in Ruby.
Tsukune and a powerful mage from the other fandom could be an interesting pair. Tsukune's vampiric powers combined with the mage's magic could create some really cool combat scenes and an interesting dynamic as they learn from each other.
The Ashen One would be really interesting. They are a resilient and battle - hardened character. In Game of Thrones, they would be like a mysterious force. Their combat skills and ability to face all kinds of terrifying enemies in Dark Souls would make them a formidable presence in the political and war - torn landscape of Westeros. They could potentially be a wild card in the power struggles between the houses.
Gray and Sango might make for an exciting pair. Gray with his ice - make magic and Sango with her weaponry skills. Gray could create ice weapons and structures to assist Sango in battle, and Sango could show Gray some of the more traditional combat techniques. Their personalities are also quite different, with Gray being more laid - back (most of the time) and Sango being very determined and focused on her goals.
Definitely Cortana and Tyrion Lannister. Cortana is highly intelligent and has access to a vast amount of knowledge. Tyrion is known for his wits. They could form an alliance where Cortana provides strategic advice based on her analysis, and Tyrion uses his political acumen to make things happen. Their conversations would be really fascinating as they come from such different worlds but are both very clever.
