Hmmm. I should probably have thought to ask this before, but better now than later:
@Swordomatic, how would Pandora rate herself against the two biggest threats on Baal that we know of? Those being of course the Swarmlord and Ka'Bandha. This kind of affects this vote already, but becomes of course even more important if Baal is chosen. I'm asking because as our encounter with Skarbrand showed us, different match-ups depend on more than just raw power, which is of course still important by itself:
For example, while broad immunity or resistance for psychic powers is expected from the Exalted of Khorne, how well does that apply to Pandora's Divination skills? Was Skarbrand the rare exception of a situation where Pandora's sight was considerably less effective on the battlefield, and almost completely useless against Skarbrand itself? Or should we expect this from
all of the Greater Daemons of Khorne, though likely not on the same level of complete immunity like with Skarbrand? And how well has the Hive Mind done in this category? Has it also managed obsuscate some details from Pandora, that were only later revealed to her? Because that might make cornering or luring the Swarmlord and the Norn Queens for a sudden God Mode -ambush a lot harder.
And more on Swarmlord, I would guess that the problem with it will be not so much in its durability if facing Pandora in the God Mode, but in the ability of the Hive Mind to remake it. While I assume that Pandora herself can't be certain about this before she tries, I'm hoping that at the very least she can disrupt, damage or in some other way sabotage whatever process that the Swarmlord and the Hive Tyrants have. Because we should have at least a chance, considering how heavily the Hive Mind relies on the Warp and from the fact that the Tyranids reborn this way have their memories intact up to their moments of death. And so while the physical form of the Swarmlord requires probably just biomass, the genetic information and the right incubation environment... Well, its mind, the most dangerous thing about it? That seems like a completely different thing.
