He is 26 dimensional + being
His single thought is enough to shatter Outerversal being
He is based on Naljian and is not actually Naljian kinda like Brainstorm is based on crab but is far superior to crab....
Is beyond Time,Space,Void,possibility,non possibility,Impossibility,Logic,non space,matter,non matter,anti matter,dark matter,dark energy,speed and physical or non physical laws
Even transforming into him would cause Omniverse to burst out due to his energy
He is beyond everything and anything
He can do anything and everything
He not be hurt by wish or magic or any thing
Cannot be beaten in hand to hand combat
Is omniscience
Is omnipresent
Is Nigh Omnipotent
His each atom is pure representation of Omniverse. But any damage to Omniverse has no direct or indirect effect on him
Azmuth asked Ben never to transform into him
Even thinking of this alien allows Ben to beat Dagon level being
He is truly match less
Also his powers cannot be copied or removed or absorbed or damaged
By any way
According to Naljians themself 99.999999% of Omnitrix data is just to assure that Ben never transforms into this alien
Hope that help
Yes I know he is toooo OP to be comprehented by Galvan mind
