You can combine the traits of different characters from the Fate Kaleid Liner series. For instance, take the magical abilities of one character and the personality of another. This will result in a new and unique character.
Experiment with different power combinations. Let's say a character has the power to manipulate space like one Fate Kaleid Liner character and the power to read minds like another. This unique power combination will make the character stand out. And don't forget about their appearance. You can mix and match the outfits and looks of different characters to create a visually distinct new character.
Maybe a time - travel based crossover. A character from Fate Kaleid Liner accidentally travels back in time and meets the younger versions of other characters in the series. This could lead to changes in the timeline and they would have to work together to fix any potential disasters that their meeting has caused, all while trying to find a way back to their own time.

To create unique characters, start with their backstory. For example, a character could have grown up in a hidden part of the 'game of fate' world, away from the main action, which gives them a different perspective. Give them a distinct personality trait, like being overly superstitious in a world full of calculated risks. Their appearance can also be unique, perhaps having a rare mark on their body that is related to an old legend in the game's lore.
Typically, characters from the Fate universe such as Illyasviel von Einzbern are main characters.
You can combine the traits of characters from both series. For example, a character could have the Sharingan from Naruto and the wings of a devil from Highschool DxD. This would give them a very distinct look and set of abilities.
