A bit late for this whole Symbi-tober thing, so instead of it I'll just draw a bunch of Symbiotes every so often based on themes, and at some point, probably some based on characters.

So, time for the Horsemen of the Apocalypse! Starting with the White Horseman, Pestilence.
Yes, yes, yes. The White Horseman is at times Conquest, and Pestilence makes more sense to be Green, but...heh...I wanted to get creative.
I tried to make this one look incredibly diseased looking, as if the Symbiote itself was this slithering mass of disgusting disease that would infect and corrupt anything it touched, while barely holding itself together, mutation being rampant, enormous boils filled with who knows what, and its arms constantly producing a sickening bile which it can just fling at opponents to immediately contaminate them.
Had fun here, in case it wasn't obvious.
