Why is thor rune king considered so powerful ?

Why is thor rune king considered so powerful ?

that is, he receives the power of Odin from the outside, so this is not his power, then he is facilitated from the outside, but not from its own power

then he doesn't kill those who are in the shadows, but he cuts the thread that it makes the ragnarok a cycle, and therefore, no livelihood, those who are in the shadows would starve, so he does not win anyone, then those who are shadows are born to Demiurge, therefore they are parts of his essence, but the Demiurge is the life force of the earth's biosphere, therefore he is not very powerful

well, I do not understand much

i am no expert on thor but he did broke a wall that surtur(he was considered a equal to odin) and his entire army couldn't break by just one blast.He was omniscient(or whatever it is spelled)

the one above shadows were vastly superior to odin but RKT did stood up to them.....and IIRC he did defeated them

well odin is very powerful and RKT is more powerful than odin so yeah he IS powerful

But he didn't win the one above shadows !

He could snap his fingers and make beings crumble into dust

The wording of your post does not make much sense, but from trying to understand it.

There is no evidence that Those Who Sit In Shadow are part of the Demiurge. We have no idea where they come from. We have no idea how powerful they were. He did defeat them since they were powerless to stop him and were implied to be heavily tied to the Loom of Fate. There are more subtle forms to power besides two fists sluggin it out.

That a lot of that power comes from the outside does not matter. Once it is within Thor it is part of him and therefore his power. The Odinforce alone makes Thor as powerful as Odin or Zeus and more powerful than pretty much anyone on Earth or short of Galactus in space. The knowledge of the runes greatly enhanced Thor's knowledge of the universe especially of life and death. He learned how to use the Odinforce much more efficiently. So whereas King Thor would have tried to blast Mangog into nothingness Rune Thor simply dissolved him by undoing the spell that created him. Knowledge of the runes granted Thor knowledge of the truth of Those Who Sit in Shadow and of the nature of Asgard.

The Loom of Fate was the means Those Who Sit in Shadow controlled the destiny of the Gods of Asgard. Thor was somewhat outside of this because he was of both Asgard and Earth and giving him a mortal identity further outside of their control. Destroying the Loom of Fate was supposed to end the cycle of Ragnarok and free them to pursue their own destinies. This is what Thor intended when he brought back Asgard on Earth. It is also one reason Loki can be something other than a villain. At least, that was the point of all of this. Other writers have sort of changed some elements of it back.

A strong argument could be made that Odin had the same power and knowledge as Rune Thor. He sacrificed his eye and hung on the world tree for the same knowledge and already possessed the Odinpower. However, Thor's earthly nature allowed him to do what Odin could not and break the cycle. Further, Rune Thor displayed a level of maturity Odin often lacks.

So yes, Rune Thor is incredibly powerful. The Odinpowered grantes Thor raw might. The runes grant him insight into the universe to better understand its cycles to manipulate those and better control over the Odinforce so he can do things he could not have done before. Instead of trying to hammer everything into submission like he often tries he learned how to adjust the flow of events to produce the outcome he desires and approach things from other ways instead of direct, brute force.

Thor minus the Odin Force is incredibly powerful. Herald-level character with both physical and magical abilities on a planetary (if not more) scale.

Thor with the Odin Force is a Skyfather of the highest order. If we are to accept that Odin is the most powerful Skyfather of the Earth pantheons, then Thor with the Odin Force is even more powerful. The reason Odin bore a child (Thor) with Gaea (the Elder Goddess of all Earth's pantheons) was to create, potentially, the most powerful deity in existence. Even without the Odin Force, this lineage is why Thor is considerably more powerful than his Asgardian (Aesir) brethren.

Thor inheriting the Odin Force, as well as the knowledge of the Runes gives him galaxy-level (if not more) magical/cosmic abilities as well as an unimaginable amount of knowledge of the inner-workings of the universe, as seekquaze pointed out.

Odin didn't possess the same knowledge as RKT. RKT sacrificed both eyes and hung on the tree until he actually died rather than just for 3 days which gave him full knowledge of the runes and rune magic. The OdinForce told him he had to go further than Odin went in order to end the cycles.

Well in truth the way it sounds as if the people whom sit above where not to smart or that powerful. So one has to wonder how they could have lasted that long.

I am very much a avid Thor fan but did not like how that was done at all.

I have always found this to be debatable. Odin knew of the cycles and that TWSAIS were manipulating the Asgardians. He learned of it each time he sacrificed his eye and hung upon the world tree. He was unable to do anything about it because Odin was fully Asgardian. He was under the control of the Loom of Fate which TWSAIS controlled. One reason he fathered Thor was to have someone who was not fully Asgardian who might be able to do something about it.

The Odinforce told Thor he had to go further because if he merely sacrificed a single eye and went to the point of death he would only be repeating Odin's sacrifice which would be meaningless. Remember, Odin was the one who originally discovered the runes and secrets of life and death through his sacrifices.
