One common quote on evil in fantasy novels could be 'Evil is not born, it is made.' This shows that in many fantasy worlds, characters are not inherently evil but are shaped by their circumstances. For example, in 'The Lord of the Rings', Gollum was once a normal hobbit - like creature called Sméagol. But the power of the One Ring corrupted him over time, making him evil. This quote emphasizes the idea that external forces can turn a being towards the dark side.
In 'A Song of Ice and Fire', there's the line 'The night is dark and full of terrors.' It represents the unknown and often evil that lurks in the dark. It gives a sense of dread and the omnipresence of evil in that fictional world. The Others, the ice - based undead creatures in the story, are a manifestation of this evil that comes with the night.
One quote could be 'The monster's thoughts were as quick as his greed or his claws: He slipped through the door and there in the silence snatched up thirty men, smashed them unknowing in their beds and ran out with their bodies, the blood dripping behind him.' This shows the evil of Grendel as he brutally kills the men. It emphasizes the contrast with the good that Beowulf represents when he comes to fight this evil.
Often, other dragon slayers are paired with Ryu. They can have different fighting styles and come from different backgrounds, which makes for an interesting dynamic when they work together.
It depends on what you mean by 'famous'. If 'Ryu' is a common name in a certain community or within a specific type of media, there could be a story that is well - known among that group. For example, in the Street Fighter series, there is a character named Ryu. But if this is not related to that, it's still unclear what the 'hot ryu story' might be.
Luffy from 'One Piece' could also be an interesting crossover. Luffy's stretchy abilities combined with Ryu's martial arts would make for some unique fight scenes. They could also learn from each other's determination and loyalty to their friends.
A quote that represents the evil in the story is 'Out from the marsh, from the foot of misty hills and bogs, bearing God's hatred, Grendel came, hoping to kill.' It clearly shows Grendel as a bringer of evil. In contrast, Beowulf is the force of good. For example, when he says 'I shall win the gold by my courage, or else mortal combat, doom of battle, will bear your lord away.' This shows his determination to fight for good, in this case, to win the treasure which is a symbol of victory over evil.
A common theme is friendship. Sakura and Ryu are often depicted as having a deep and loyal friendship that withstands many tests. For example, in some fanfictions, they might have to face a powerful enemy together but their friendship never wavers.
One common theme is power. Since the Ryu concept often brings in strong and unique powers, the fanfictions usually explore how these powers are developed and used in the Naruto setting. Another theme is identity. Characters with Ryu elements often have to figure out their place in the world, whether they are accepted or not.
