Rider from Fate Zero and Ozymandias from Fate Grand Order could be a fascinating pair. Both are powerful and prideful kings. They could engage in a battle of wits and power, or they could find common ground in their kingly natures. Maybe they would discuss their different kingdoms and the ways they ruled, and their conversations could be filled with grandiosity and philosophical debates about leadership and power.
One idea could be to have the Servants from Fate Grand Order interact with the events and characters of Fate Zero in unexpected ways. For example, Mash could end up in the middle of the Fourth Holy Grail War and try to prevent some of the tragedies from happening. She might team up with a young Kiritsugu, using her knowledge from the future to guide him. Another could be that a Grand Order Servant like Artoria Alter gets involved in the war and changes the power dynamics completely, as her dark and powerful nature would be a wild card in the already complex Fate Zero setting.
One of the popular pairings might be Saber from Fate Grand Order and Ruby from RWBY. Saber is a well - known and powerful character, and Ruby is the main protagonist of RWBY. Their combination can create some interesting dynamics, with Ruby's enthusiasm and Saber's more serious and noble nature. Another could be Archer from Fate Grand Order and Weiss. Archer's snarky and confident attitude might contrast well with Weiss's more refined and sometimes uptight personality.
Naruto and Saber would be an interesting pairing. Saber's noble and chivalrous nature combined with Naruto's energetic and optimistic personality could create a unique dynamic. They could learn from each other's fighting styles and moral codes.
Fate Grand Order Tiamat fanfiction can also take a more creative turn. It could be set in an alternate universe where Tiamat has a different origin or purpose. Writers might explore her personality in more depth, perhaps showing a side of her that is more benevolent or at least more nuanced than what we see in the game.
Tiamat is such a powerful being in Fate Grand Order, and fanfiction gives the chance to explore what if scenarios. What if she joined forces with the heroes? Fanfictions can play with these ideas and create unique and exciting stories that deviate from the main storyline.
It adds more depth to Mash's character. By exploring different scenarios in fanfiction, fans can get a better understanding of her potential and different sides of her personality. This in turn enriches the overall perception of Mash within the Fate Grand Order fandom.
One interesting concept could be the exploration of different Servant backstories in more depth. For example, delving into the pre - summon experiences of a Servant that might not be fully covered in the game. Another could be alternative versions of the Holy Grail Wars, with different rules or participants. Also, the fanfiction might explore the relationships between the Masters and Servants in unique ways, like how they interact outside of battle situations.
One interesting concept could be the combination of different character abilities from Fate Grand Order and RWBY. For example, seeing how a Servant's Noble Phantasm might interact with a RWBY character's semblance. Another concept could be the crossovers in the storylines, like how the overarching plot of Fate Grand Order, which often involves saving the world from various threats, could mesh with RWBY's fight against the Grimm. Also, the character relationships that form between the two universes' characters can be really engaging, such as a Fate character forming an unexpected alliance with a RWBY team member.
A possible plot could be Scathach's exploration of the modern world. Since she is from an ancient time, her reactions to modern technology, culture, and society can be a great source of interesting storylines. She might be initially confused by things like smartphones or cars, but then gradually learn to use them in her own unique way. This could also lead to humorous situations, like when she tries to order food at a fast - food restaurant for the first time.
Her motherly nature. In many fanfictions, Raikou's motherly side is explored, especially in relation to other servants or the Master. She can be very protective.
