Powerful abilities are a key factor. For instance, characters like Doctor Strange in the Marvel universe possess magical powers that can manipulate time, space, and reality. This gives him an edge over many opponents. Another aspect is near - invulnerability. Characters such as Wolverine can heal from almost any wound quickly, making them hard to kill.
A great visual novel often has an engaging story. For example, if it has a plot full of twists and turns like 'Steins; Gate', it can draw players in. Good character development is also crucial. In 'Fate/stay night', the characters are complex and their relationships evolve throughout the story. The art style matters too. If it has beautiful and detailed art like 'Clannad', it can enhance the overall experience.
One of the most OP powers in fiction is omnipotence. Characters with this power can do absolutely anything without limitations. For example, in some religious and mythological stories, the supreme deities are often depicted as omnipotent. They can create and destroy worlds at will, manipulate time and space, and control all aspects of existence.
One of the most OP characters is Superman from DC Comics. He has super strength, can fly, has heat vision, and is nearly invulnerable. His powers make him extremely difficult to defeat in most situations.
Abilities are a big factor. For example, if a character can manipulate time like Doctor Strange in some Marvel stories. He can rewind, fast - forward or even create time loops, which gives him a huge advantage. Another aspect is intelligence. Characters like Batman, who don't have superpowers but are super - intelligent, can outwit most opponents.
One factor is their motivation. If their motivation is purely self - centered and involves harming others on a large scale, they can be seen as very evil. Take Darth Vader from 'Star Wars' for instance. He was initially lured to the dark side by the promise of power, and in the process, he committed many atrocities, like destroying entire planets. However, his character also has some complexity as he later redeemed himself, but during his time as a Sith Lord, he was a symbol of great evil. Another aspect is their methods. Characters who use cruel and sadistic methods to achieve their goals are often regarded as evil. The White Witch from 'The Chronicles of Narnia' froze Narnia in eternal winter and turned many of its inhabitants to stone, showing her extreme cruelty.
A character can be the most tragic when they face impossible choices. For example, like Sophie in 'Sophie's Choice' who has to decide which of her children will live and which will die in a concentration camp. This kind of choice that goes against all human nature is a major factor in making a character tragic.
A character's power often depends on the context of their fictional world. In a world full of magic, like in 'Harry Potter', someone like Dumbledore is very powerful because of his great magical knowledge and skills. He can perform powerful spells and has a deep understanding of magic. But in a more science - fiction based world, a character like the Doctor from 'Doctor Who' is powerful because of his advanced technology and his ability to travel through time and space.
Power can be defined in many ways. For some, it's raw physical strength like Hulk's in the Marvel universe. He can smash through almost anything with his brute force. But it could also be about intelligence. Characters like Sherlock Holmes have a different kind of power - the power to solve the most complex mysteries. So, a combination of different abilities like strength, intelligence, magic (if in a fantasy setting), and the ability to influence others can make a character the most powerful.
The scope of a character's influence also matters. If a character has the power to control the fate of entire universes, like Eru Ilúvatar in 'The Silmarillion', they are clearly very powerful. Their decisions can create or destroy entire worlds, and all other beings are subject to their will in some way. This kind of overarching power is a key factor in determining the most powerful person in fiction.
Well, extreme cruelty can make a character very unpleasant. For example, if a character enjoys torturing others, either physically or mentally, like some of the villains in horror or thriller novels. They might take pleasure in the pain of others without any remorse, which is really off - putting.
