Edward Connor's grandfather could be a bit of a rebel in the fanfiction. He might have had a wild youth, going against the norms of his time. He could teach Edward that it's okay to be different and not always follow the crowd. He could have had his own unique style, like wearing flamboyant clothes or having a strange hobby that no one else in the family understood.
He could be a kind of storyteller. Maybe he tells Edward all kinds of fantastic tales from his own youth, full of magic and adventure, which inspire Edward to create his own adventures. He could have traveled far and wide, and his stories are filled with different cultures and strange encounters.
One day, Edward Connor's grandfather was sitting on his old, creaky porch chair. He had a weathered face that told tales of years gone by. He remembered the days when he first came to this land, full of hope and dreams for his family. He used to take young Edward fishing in the nearby stream, teaching him patience as they waited for the fish to bite. Edward would listen intently to his grandfather's stories of the old days, and those moments became precious memories for him.
One possible plot could be that Connor and Edward meet in a post - apocalyptic world. Connor, with his advanced skills, might initially be suspicious of Edward. But as they interact, they find they have a common goal of survival. They could team up to fight against some powerful, menacing force that threatens their existence.
A fanfiction could be about family ties. Maybe Connor discovers he has a distant relative who was part of Edward's crew. He sets out to find this person and in the process, uncovers more about his family's past. Along the way, he meets Edward's ghost or some kind of spiritual manifestation of him. Together, they work to protect a hidden Assassin stronghold from the encroaching Templars.
One possible plot could be that Connor, being from a later time in the Assassin's Creed timeline, stumbles upon some ancient records or a hidden memory that leads him to Edward. They might initially be at odds due to their different time periods' ways of life. Edward, being more of a swashbuckling pirate - assassin, could teach Connor some new combat techniques or ways of navigating the high seas that Connor hadn't experienced in his mainly land - based adventures. They could also bond over their shared goal of fighting the Templars, with Edward sharing his experiences from the earlier days of the conflict and Connor bringing in his knowledge of the more evolved Templar plans in his time.
His grandfather could be a very strict and traditional ninja. He might have high standards for Naruto in terms of ninja skills and discipline.
It could be an older, more experienced android. One that has been through a lot and has a deep understanding of both the android world and human society.
Perhaps they meet in a hidden Assassin's lair. Connor, being a devout Assassin, might be initially suspicious of Edward's pirate - Assassin past. However, they soon realize they have common goals in terms of fighting against the Templars. They could team up to take on a powerful Templar presence in the area. Edward's experience in dealing with various factions could be valuable to Connor, while Connor's connection to the land and its people could give Edward a new perspective.
Begin by creating a conflict that involves both Edward and Connor. It could be a new Templar threat that has roots in Edward's time and resurfaces in Connor's. Develop their characters further by giving them internal struggles. Maybe Edward is haunted by his past actions as a pirate, and Connor is struggling with his identity as an Assassin in a changing world. As you write, keep the pacing right. Alternate between action - packed scenes and more reflective moments. And most importantly, let your love for the Assassin's Creed series shine through in your writing.
He could start off as a loner, not really understanding the quirk - based society. But as he interacts with the students at UA, he could learn the value of teamwork. For instance, in group battles, he'd realize that combining his alchemy with others' quirks can create more powerful effects.
In a fanfiction, their meeting could be a catalyst for a great adventure. Imagine if they were both after the same powerful artifact. Connor's tracking skills and knowledge of the land could combine with Edward's sailing and naval combat expertise. They would have to learn to trust each other quickly. Edward could introduce Connor to the concept of a pirate crew as a sort of family, which might make Connor reflect on his own relationships within the Assassin Brotherhood. And Connor could show Edward the importance of nature and the spiritual side of the Assassin's creed, which Edward might have overlooked in his more material - and treasure - focused adventures.
