but can any of these be completly invulerable to harm? no...
the only weapon that can kill kain is a soul devouring weapon, that means that superman at full strength, Hulk, hell anything that cannot devour his soul is completly useless to him no matter how high they are, thats a pretty good feet in itself..
also energy manipulation yes, but boundless, if it states said character through in this case the energy emblem on his sword can do said feet, then it cannot be denied, he has infnite magical power for defniate, his energy manipulation howver he has never "used" its been said he can do it, so PIS ftw...
Kains speed is not great, its been stated faster than any human when he was young kain but hes evolved since then, although he has many other powers, for example a fast being such as superman/surfer can do nothing to him, they have no soul devouring powers as far as i know, same with Kos-Mosw who has been put at sky-father tier...Kain on the other hand has powers over souls and energy and time stop/slow..these feets combined i think can put him in a good high father level for sure.
when he has the full balance emblem he is gaining powers from a source higher than that of the pillar guardians and his powers theresfore would be greater than theirs...and they can do the feets i posed..his dimesion combat teleportation Debel said is gameplay, what hes doing is breaking through dimensional barriers and at the same time can warp reality so that all his opponents take the same damage, if these feets are nothing on sky-father then why is Kos-mos on there.
Kain has shown immunity to mind control (BO2) and by the end of the game seems to be able to hide himself from Omnicient beings to an extent.
kains only weakness is soul devourers (although he has resistence, its what can kill him) and his speed, he has also the ability without his sword to freeze single beings in time, stun brains so they become cataconic, control weather (lightning) without the sword, but yes his sword is a main power weapon, like Thors hammer
