Obviously, Bro Strider himself is a main character. Often, his friends or family members might also be important characters. For example, if it's a fanfic about his younger days, his brother might be a key character.
Occasionally, Dirk Strider smiles in the comic. It's not a common occurrence, but when it happens, it's often tied to significant plot developments or emotional connections with other characters.
The story in AC Origins is centered around Bayek's fight against the Order of the Ancients in Egypt. It shows the birth of the Creed. In AC Odyssey, the story is more complex. Kassandra/Alexios' story involves not only their own family mystery but also the politics and power plays in different Greek city - states. Origins' story has a more somber and serious tone due to Bayek's personal losses. Odyssey's story can be more colorful and full of Greek mythology elements.
In terms of the plot of such a fanfiction, it could involve them teaming up against a common enemy. Maybe they have to face some sort of interdimensional threat. Their different abilities, Dave's with his time - related powers and Sans' bone attacks and teleportation, would make for an exciting combination in battle.
One great Bro Strider fanfic could be 'The Adventures of Bro Strider'. It really delves into his character, showing his cool and collected nature while also exploring his relationships. Another is 'Bro Strider: A New Perspective' which gives a different take on his role in the story.
Another common theme is the relationship between characters. In a crossover, Hiryu might form new alliances or rivalries. There could be a theme of trust - building or betrayal. Also, some crossovers might have a theme of self - discovery for Hiryu. As he interacts with new characters and situations, he may learn more about himself and his place in the greater multiverse of the crossover.
Another theme is discovery. As baby Dave grows and starts to show his unique personality, the other characters are constantly discovering new things about him. This can include things like his hidden talents or his strange quirks that are a hint of his future self. It's like they're uncovering the pieces of what will become Dave Strider as we know him in the original story.
One idea could be a crossover between Strider and a popular superhero universe. For example, Strider could team up with Spider - Man to fight a common enemy in New York City. Another idea is a crossover with a fantasy world like Middle - earth. Strider could journey with the Fellowship to defeat the Dark Lord. A third idea is a crossover with a post - apocalyptic world where Strider's skills are put to the test in a desolate landscape.
The main difference is the setting. Origins is in Egypt and Odyssey in Greece. This leads to different cultural elements in the stories. Origins' story is more about the origin of the Assassins. Odyssey is more about the hero's personal journey. Also, Origins has a more straightforward story arc compared to Odyssey which has more branching storylines.
The AC3 story has its merits. It offers an interesting plot with twists and turns. However, it may have a few flaws that could affect your enjoyment depending on what you look for in a story.
