Powerful weapons in fiction usually change the plot by creating a sense of conflict. For example, in "The Lord of the Rings", the One Ring is the center of the entire conflict. Different factions are either trying to destroy it or use it for their own evil purposes. This drives the story forward as the characters have to make difficult decisions regarding the Ring.
Powerful weapons can also change the plot by changing the power dynamics between characters. In "Harry Potter", when Voldemort gets hold of the Elder Wand, he becomes even more powerful and dangerous. This forces Harry and his friends to come up with new strategies to defeat him. In fictions, these weapons can also create alliances or break them. If a group has a powerful weapon, others may ally with them to get access to it or oppose them to prevent its misuse, which significantly reshapes the plot.
In science fiction, melee weapons often have extraordinary abilities. For example, lightsabers can cut through blast doors, while real - world swords can't do that. Also, some science - fiction melee weapons are energy - based, like the energy blades in Halo, which don't exist in the real world.
Often, it can create internal conflicts for the characters. For example, if a character has been one gender for a long time and suddenly changes, they may struggle with their new identity and how society views them. This can drive the plot as they try to find their place. It can also lead to new relationships and power dynamics. If a male - turned - female character enters a male - dominated society in the story, they may face different challenges and opportunities compared to before, which twists the plot in unexpected ways.
Take the Keyblade in 'Kingdom Hearts'. It enables Sora to travel between different worlds and fight against the Heartless. This means he can interact with characters from various Disney and Final Fantasy universes, which makes for a really complex and interesting storyline. The Wardrobe in 'Chronicles of Narnia' changes the lives of the Pevensie children. It transports them to a whole new world where they have to face different challenges and grow as characters. And the Green Lantern's Power Ring allows the Lanterns to protect different sectors of the universe, and their adventures and battles are all centered around the power and use of this ring.
They can change the original plot by altering Naruto's relationships. For example, if he's reincarnated as a different character, he might form new friendships or rivalries. His reincarnation could also lead to different power developments. Instead of following the same path to gain his powers, he might have to find new ways in his reincarnated form.
Wish - granting items in fiction usually act as major plot devices. For instance, in the story of the Monkey's Paw, the wishes made on it lead to tragic consequences. This creates a sense of horror and suspense in the story. In 'Aladdin', the Genie's lamp allows Aladdin to transform his life from a poor street urchin to a prince, driving the plot forward as he tries to win the princess's heart while keeping his true identity a secret.
Magical stones in fiction usually act as MacGuffins. For example, in 'Harry Potter', the Philosopher's Stone drives the plot as everyone is after it. It creates conflict and danger. In 'The Lord of the Rings', the One Ring is the central object that shapes the whole story. Characters are either trying to destroy it or use it for their own gain, which leads to a series of adventures and battles.
In science fiction, superpowers are a major factor in plot development. They can be the cause of a character's isolation if their power is feared or misunderstood. This can then lead to a journey of self - discovery and acceptance. On the other hand, superpowers can also bring characters together. A group of super - powered individuals might form a team to fight a common enemy. Their combined powers and how they interact with each other then becomes an important part of the plot. For example, in the Avengers, each member has their own unique superpower, and how they work together to protect the world is a central aspect of the story.
Evil books in fiction can function as a source of corruption. Take the 'Book of Eibon' in some horror literature. It spreads its evil influence over those who read it, causing them to commit immoral acts or become possessed by dark forces. This then sets off a chain of events in the plot where either the protagonist has to stop those influenced by the book or has to find a way to seal the book's power away. And in some cases, the book might be used to raise dark armies or summon demons, which directly impacts the direction of the plot as the characters have to deal with these new threats.
Critters in science fiction can be the source of conflict. For example, the Xenomorphs in 'Alien' are a constant threat to the human characters, driving the plot as the humans try to survive. They create a sense of horror and danger that keeps the story tense.
Companies in science fiction influence the plot in multiple ways. In 'Resident Evil', Umbrella Corporation's experiments with the T - virus are the root cause of the zombie outbreak. Their attempts to cover up and control the situation just make things worse. This leads to the heroes having to fight against hordes of zombies and the corrupt elements within the company. Another example is Stark Industries in the 'Marvel Cinematic Universe'. While it starts as a weapons manufacturer, Tony Stark's change of heart and the company's shift towards clean energy and superhero technology play a major role in many storylines. The company's resources and inventions often provide the means for the heroes to fight villains and save the world.
