King Thor is basically Odin. Depending on who you talk to 8th Day is either 1."almost 100% Cytorrak" or 2."100% Cytorrak". In scenario 1, King Thor wins. In scenario 2, it depends on whether or not you think Cytorrok is more powerful than the Skyfather and his power. Personally, I'd side with the Asgardians, so my vote would be for King Thor in either case, but there will be those who disagree. It's really pretty close so I wouldn't argue too strongly for or against either side.
From what ive heard original Juggernaut can withstand a full powered Odin force blast with out being harmed so how is King Thor gonna take on this ultra powerful Juggernaut
Oh and to answer your question Eight Day Juggernaut is not full power of Cytorrack Trin Juggernaut is the one with the full power of Cyttorrack He was so strong He could punch through dimensinonal walls and even Juggernaut fell under His total controll i think that Cytorrack is pretty powerful not as powerful as Set from the elder god or Chthon He is on the same level as the gods whom Dr Strange sometimes asks for help as Argomatto and the like.
Odin is afriad of Cyttorak, Cyttorak is lile the guy all the skyfather types bannded together to imprison him.
BUT, 8th day Jugs isnt full power Cyttorak, 8th day is the exact same person as normal jugs, just being mind controlled by someone who knows how to harness Jugs power.
Jugs could be 8thday RIGHT NOW if he knew how to use his power correctly.
That just shows you how powerful Jug is.
juggernaut in 8th day was pretty much ****ing normal... he wasnt any more powerful than "classic" juggernaut, just his mind was more influenced by cyttorak. he exhibited no more power than usual. please feel free to tell me where if he did i'm sure you will fall short of your goal.
