In the world of fiction, characters like Thanos are also extremely powerful. He has the Infinity Gauntlet which gives him the power to control reality, time, and space among other things. He can wipe out half of all life in the universe with a snap of his fingers. His strength and the scope of his power are truly terrifying.
The strongest beings often have superhuman strength. For example, Hulk gets stronger as he gets angrier, and his physical power is off the charts. They also usually possess some form of energy projection. Like how Doctor Strange can manipulate magic energy for various effects, from creating shields to attacking enemies.
Omnipotent beings in fiction can take various forms. There are the more traditional divine - like entities, like the Greek god Zeus in some retellings of Greek mythology - based fictions. He has the power over lightning, can change his form, and has dominion over the other gods to a certain extent. Then there are more abstract omnipotent beings. In some science - fiction stories, an all - encompassing energy or force might be considered omnipotent, which affects the entire universe and everything in it.
Some of the most powerful fictional beings are the Q Continuum from 'Star Trek'. The Q are omnipotent and can manipulate time, space, and reality at will. In the world of Japanese anime, Goku from 'Dragon Ball Z' is also very powerful. His power levels keep increasing throughout the series and he can perform incredible feats of strength and energy projection. Another is Lucifer Morningstar from the 'Sandman' series. He is an extremely powerful fallen angel with a vast array of powers.
Galactus from Marvel Comics is an example. He is a cosmic entity with near - omnipotent power. He devours planets to sustain his energy, and his power is so vast that only a few heroes can even attempt to stop him, and usually only through great sacrifice or clever strategies.
In the 'DC Comics' universe, Darkseid can be considered a near - omnipotent being. He has incredible strength, can control minds on a large scale, and his Omega Beams are extremely powerful. His goal of universal domination makes him a formidable and all - powerful force in the DC world.
Omnipotent beings can act as a catalyst for character development. Facing an all - powerful entity forces the characters to reevaluate their own beliefs, skills, and values. They may have to find new ways to overcome challenges that are far beyond their normal capabilities. This can lead to significant growth in the characters, which in turn shapes the overall plot as the changed characters make different decisions.
There are so many candidates for the top 10 most powerful fictional beings. Starting with Superman, his powers are almost limitless on Earth. Doctor Manhattan has god - like powers in 'Watchmen'. Galactus is a planet - devouring entity. The One Above All in Marvel is like the supreme being. The Presence in DC is omnipotent. Scarlet Witch's reality - warping abilities are formidable. Morgoth was a primeval evil. Goku's strength growth is amazing. Yoda has great wisdom and Force power. And Azathoth is a being of unfathomable power in the 'Cthulhu Mythos'.
One could consider characters like Superman. He has super strength, speed, and various other powers. Another is Doctor Manhattan from 'Watchmen'. His ability to manipulate matter at a quantum level makes him extremely powerful. And then there's Galactus, a cosmic entity who devours planets for sustenance.
