Definitely a godlike guardian of a sacred place. This character would be very territorial and Yuri would have to prove himself worthy to enter. Another character could be a young god who is curious about Yuri and tries to befriend him, which gets Yuri into all sorts of adventures. And an outcast from the godlike society who has unique powers and teams up with Yuri because they both feel like outsiders in different ways.
One interesting character could be a powerful mage from the world Yuri crosses into. This mage could initially be wary of Yuri but then come to respect his skills. Another could be a godlike being who is a trickster. This character would constantly test Yuri and create humorous and challenging situations for him. And also, a young apprentice in this new world who looks up to Yuri and wants to learn from him.
Well, for sure a female warrior from the godlike world. She has her own code of honor and at first clashes with Yuri but then they form an alliance. There could also be an old sage who has knowledge about the connection between Yuri's world and this new one. He could be a guiding figure for Yuri. And then there's a shadowy figure, a kind of anti - hero in this world, who has his own motives regarding Yuri's presence and the changes it might bring.
One possible plot could be that Yuri Lowell is transported to a world where there are godlike beings. He has to learn their ways and powers to find a way back home. Along the way, he meets a character who is a mix of his world's elements and the godlike nature of this new world. They team up to face challenges and in the process, Yuri discovers new aspects of his own abilities.
A common theme is adventure. Since Yuri is often a character associated with action and exploration in his own game, when crossed over, he often embarks on new adventures in different fictional settings. Another theme could be friendship. Meeting new characters from other universes and forming bonds with them.
Sure. You can check out some fanfiction platforms like Archive of Our Own. Just search for 'Yuri Lowell crossover' there, and you'll find a variety of works. Some might cross him over with other game characters from different RPGs, creating really interesting new storylines.
I think Gandalf from 'The Lord of the Rings' would be an excellent choice. He has his own form of magic and is a very wise character. Combining him with Harry in a godlike crossover could lead to some amazing adventures. Another good character could be Yoda from 'Star Wars'. His connection to the Force and his wisdom could interact interestingly with Harry's world of magic.
Sasuke is a great character to include. His cool and brooding personality can create interesting dynamics in crossovers. For example, if he crosses over into the world of Attack on Titan, his skills as a ninja would be put to the test against the Titans. Another interesting character is Kakashi. His laid - back yet highly skilled nature can add humor and action to crossovers. He could be a great addition in a crossover with the world of Inuyasha, sharing his knowledge of combat and jutsu.
Phos from 'land of the lustrous' is an interesting character to include. Their complex character development throughout the original series can bring a lot to a crossover. Another could be Kongou, as their role as a sort of authority figure can create interesting dynamics in a crossover. And characters from other universes with strong personalities, like Naruto from the 'Naruto' universe, can also be great as they can contrast or complement the 'land of the lustrous' characters.
One interesting character to include could be a brave knight from a medieval - themed world. The contrast between the knight's chivalry and Ratbag's cowardice would create great tension and comedic moments. Another could be a magical wizard who constantly tries to force Ratbag to face his fears through various spells and challenges. Also, a sly thief from another world could team up with Ratbag, and together they get into all sorts of misadventures while the thief tries to teach Ratbag some of his more devious skills.
Definitely consider including Batman from the DC universe. His detective skills and strategic mind would be a great addition. He would be intrigued by the mystery and power of the Gate of Babylon and would try to analyze it from every angle. His interactions with Gilgamesh would be full of tension as they both are used to being in control.
Anthony Bridgerton would be a great character to include. His strong sense of family and his often stubborn nature could lead to some interesting clashes in a crossover. Say, in a crossover with a fairytale world like Cinderella. He might initially be against the idea of the Bridgerton family getting involved with the magic and 'foolishness' of the fairytale world, but then gradually change his mind.
In Mystreet, Aaron would be an interesting choice. His mysterious past and combat skills could add a lot to the crossover. For Skymedia, a character who is an expert in technology or has some sort of unique power related to their world's mechanics. When these characters meet, there could be some really cool moments. For example, Aaron might be in awe of the technology - based powers of the Skymedia character, while the Skymedia character could be intrigued by Aaron's more traditional combat skills.
