Another factor is the character's ability to overcome any obstacle or enemy. A character who has no real weaknesses and can always find a way to win, regardless of the situation, could be seen as the strongest. This is somewhat like Batman. He doesn't have superpowers but his intelligence, strategic skills, and unwavering will allow him to defeat opponents much more powerful than him on many occasions.
I think it's a combination of different aspects. First, physical strength is important. Characters like the Hulk have incredible physical strength that allows them to overpower most opponents. Second, special abilities matter. A character like Scarlet Witch with her reality - warping powers is extremely formidable. And finally, the character's ability to grow and overcome challenges. A character who can constantly evolve like Naruto, from being a weak ninja to one of the most powerful, can be considered strong in the world of fiction.
Power levels are a big factor. If a character can do things like destroy planets or universes with ease, that's a sign of great strength. For example, Galactus in the Marvel Universe has the power to consume planets. His raw power is off the charts.
Power is a big factor. For example, characters like Thor in the Marvel universe have god - like powers. They can control lightning, are super strong, and have great durability. Their powers put them at a very high level among fictional characters.
Power levels often play a big part. For example, if a character can control time or manipulate reality like Scarlet Witch in the Marvel Universe, that's an incredibly powerful ability. They can rewrite the rules of existence, which gives them a huge advantage over others.
Raw power is a big factor. If a character can effortlessly destroy planets or move mountains, like Galactus in Marvel Comics, that's a sign of great strength. He can devour entire planets to sustain himself, which shows his extreme power.
Power and abilities play a huge role. For example, if a character can manipulate time like Doctor Strange in the Marvel Universe, that gives them an edge. They can stop time, reverse events, or see into the future to outwit their enemies.
Immortality or near - immortality is important. Characters like Dracula in some fictional portrayals are very difficult to kill and have superhuman abilities. But it's not just about not dying. The ability to adapt and overcome any situation, such as Sherlock Holmes' mental acuity in solving the most complex cases which gives him an edge in his own fictional realm.
There are many strong characters, but perhaps Goku from 'Dragon Ball' is among the strongest. He has multiple super Saiyan forms, each increasing his power exponentially. He has fought against some of the most powerful villains in the universe and has always managed to come out on top through his sheer willpower and combat skills.
Well, Goku from Dragon Ball might also be a top contender. His power levels keep increasing throughout the series. He can achieve different levels of Super Saiyan, each with exponentially greater power. He has fought against some of the most powerful foes in the universe and has always found a way to get stronger and win.
One could argue that Superman is among the strongest. He has super strength, can fly, has heat vision, and is nearly invulnerable. His powers are so vast that he can move planets and survive in the harshest of environments.
