I think a punished Voidspawn would be more likely in this setting. The Horde is bent on consuming as many living souls as possible; if you're too weak, or take the mortals' side, they'll devour you so as not to waste mana. So Dexter may be a weak Voidspawn who escaped his gruesome fate and took a fallen body on his way out.

^ I like that suggestion a lot, it feels more cohesive than my original plan. Plus my inspiration for Dex was character archetypes like Zim and Moxie voiced by the same guy who voiced Zim.
