Okay, so this is my way of figuring out how powerful current DS is, by having him go toe to toe with Thor at his strongest. Thor has the power of cosmic like he has as a herald of Galactus, and the Odinforce. Assume he can do anything that Jane Thor, Odin and the Surfer(minus the speed feats as i don't think he obtained any speed increase when he became a Herald, if he did obtain a speed upgrade then sure, otherwise; assume he is no faster than Jane Thor at best) can do.
How does he fair against Darkseid, who took down the Quintessence?(Remove him taking down the Spectre from the equation due to how radically the Spectre can vary in power on an inconsistent basis depending on the plot). Remember that current DS is also supposed to be a composite of his past avatars as well, so any feats they have done automatically go to him.
So how does this fight go down?
