The Immortal Emperor
DK doesn”t even think he can beat the hands unless WW surrenders to him. He says if they keep fighting, the Hands will be stronger than both of them, but if she surrenders to him, he”ll have the power to destroy the Hands. And given WW defeats Darkest Knight and proceeds to get instantly erased by the Hands along with the entire Multiverse, I have my doubts that the Darkest Knight wouldn”t have gotten erased himself barring some exponential power boost he would have acquired from the Heroes surrendering.
As for the Chronicler, it seems heavily implied that he is beyond any force from within the DC Multiverse, as the comic constantly makes reference to the fact that he is born from and directly protected by the Source and the Greater Omniverse, and that this puts him “several rungs on the cosmic ladder” beyond Metron according to Metron himself. If he”s being directly protected by the Source, I highly doubt Perpetua/DK/Golden WW could defeat him.
