For example, Alistair could be reimagined as a mage instead of a warrior. This would change his entire backstory. He might have been hidden away in the Circle of Magi instead of being raised in the Chantry. His relationship with Morrigan would also be different, as they would both be mages with different views on magic. Another character, like Leliana, could be a bard who is actually a spy for a new, unknown organization. Instead of working for the Chantry, she has her own motives and secrets. And Varric could be from a noble family, but he has turned his back on that life to become a storyteller and adventurer in the underworld of Kirkwall.
One idea could be a world where the darkspawn and the elves form an alliance. They might come together out of mutual desperation, the darkspawn seeing the elves' connection to the Fade as an advantage, and the elves seeing the darkspawn's numbers as a means to gain power and protection from the other races. Another plot could involve a Dragon Age universe where magic is completely outlawed. Mages would have to go into hiding, and templars would be more like a secret police force, leading to a lot of underground resistance and intrigue. A third idea is an alternate universe where the Qunari have taken over most of Thedas. Their strict way of life would reshape the cultures and societies of the other races in ways that are both fascinating and disturbing.
One way Superman could fit into the Dragon Age universe is through his superhuman strength. He could be seen as a powerful entity, like a very strong Grey Warden. His ability to fly might be considered a form of magic in the Dragon Age world. For example, mages in Dragon Age can use magic to levitate, and Superman's flight could be seen as an extreme form of that.
It can start with imagining a major event in the original story happening differently. Maybe Toothless never met Hiccup, or the dragons have different powers. That's a good starting point.
In a Dragon Ball alternate universe fanfiction, there could be a plot where all the Saiyans survived the destruction of Planet Vegeta. They form an alliance with Earth and together they face new threats from a different galaxy. This would change the power dynamics completely. There could also be a scenario where the Kaioshin are the main antagonists. They use their divine powers in a corrupt way, and the Saiyans and Earthlings have to join forces to stop them. And what about a universe where the concept of ki is different? Maybe it can be transferred between people like a currency, and battles are fought not just with strength but also with strategic ki trading.
Perhaps he meets a version of his parents who are still alive. This would be an incredibly emotional encounter for Harry. He would get to know them, and they could teach him things about magic and life that he never had the chance to learn before.
He might meet different versions of his friends. For example, a Hermione who is a powerful sorceress ruling a magical kingdom. It would be exciting as he could learn new magic from her and be part of her adventures in this alternate reality.
Vampires in 'Dragon Age: Inquisition' fanfiction can also be presented as outcasts or misunderstood beings. They may be fighting against the prejudice of the non - vampire races. Some stories might explore a vampire character's journey to find acceptance or a place where they can exist without fear of persecution. This adds a layer of depth to the existing world of Dragon Age Inquisition and gives a new perspective on the game's themes of race and power.
One possible fanfiction idea could be Harry Potter, after becoming the Master of Death, somehow gets transported to the Dragon Age world. He might use his knowledge of magic and his new - found mastery over death to change the course of events in the Dragon Age. For example, he could use the Deathly Hallows in ways that are unheard of in the Dragon Age, like using the Resurrection Stone to bring back important characters who died prematurely in the Dragon Age lore.
Well, you could create a character who is a descendant of the Yardrats but has the ability to manipulate energy in a way that no one else can. Maybe they can turn their ki into different elements like fire or water. Also, a character that is a fusion of a Kaioshin and a demon could be really interesting. This character would have a struggle between good and evil within them and possess extremely powerful and unique abilities that are a blend of the two races.
