and Eternity did NOT say he can't...he said he WON'T!!
He said he will not restore it because he can't. These powers do not belong him.
if not, why Eternity did not restore his powers if he supposedly had the power to do so?
Anyways, you seem to be adding invisible feats like: Cyttorak negating the other Octessence and Vishanti.
Cyttorak negated Seraphim and Watoomb’s attacks. What does prevent this not occur with the rest of the Principalities’ attacks? Not mention, during the Wager of the Octessence, Cyttorak’s avatar defeated most of them.
Vishanti was unable to respond Dr. Strange’s spells for aid within CC. Why? Are they afraid of Cyttorak?, are they negated by him? or are both things?
Not mention Dr. Strange was absolutely helpless, owned and was about to be killed in fast and forceful way by Cyttorak until he managed to bring Jugg in order to break free, while Nova was swiftly knocked out by Cyttorak.
Otherwise, in Agamotto’s realm, Dr Strange was able to stand a fight against him twice and even he could destroy one of his many forms (caterpillar form) by summoning Cyttorak’s Crimson Bands and other Principalities’ spells.
Obviously Dr. Strange can not defeat Agamotto in his own realm (Agamotto will be reformed himself always in whatever he wants) but at least he caused a pain in his ass for a while. Also, Dr. Strange deceived and blackmailed him.
Strange always was very humble and fearful to Cyttorak but has not been the same case with Agamotto (One of the Vishanti's members). Strange has always disrespected him so much several times.
All this prove that Cyttorak is feared by other Principalities (Vishanti), the same Dr. Strange and that he can negate all their magic spells or attacks.
Your judgement and arguments are clouded by your love for these characters...find it in youself to realize that your beloved Cytorrak and Juggs are NOT FLAWLESS!!
Your desire does not change the facts.
In your minds eye, I have not "refuted" anything you said because of your inability to admit that your favorite characters can and DID lose in these scenarios!!
I am content that we disagree!!
Again, I have no problem that you disagree with me, the point is you have not refuted anything I’ve explained.
Also, I have no problem to admit the weaknesses of Cyttorak, for example, one aspect of him (destructive or demonic form) can be banished from this physical universe, he is isolated and imprisoned himself in his own crimson universe and can only access this reality through a magical conduit, portal or via his avatar, the Juggernaut. Cyttorak’s evil influence over the mind and spirit of his avatar may be weakened if the host remains being softhearted and loses the desires to follow the path of destruction, violence, revenge, anger and lust for power. This entails as a consequence the avatar would be depowered or being excommunicated by Cyttorak.
The thing about these characters is that they were developed by Stan Lee and Jack Kirby for the sole purpose of being powerfully unstoppable (for example, when this was stated in the writer panel box about how Cyttorak overpowered the four elemental forces of the universe) and being able to promote the best effort of a good teamwork in the case of the X-Men to defeat him (the Juggernaut) without fear to try to kill him. Cyttorak is an immensely powerful mystical being that can only be used to create contrast situations within himself and to generate an existential conflict and ambivalence to his avatar.
Some prominent and reputed vinners as Deadpool or Korg think the same way.
