The mutant guy, I believe, is the "low-level" synthetic, Elden, which is the creation of the Francis fellow that Galgo is holding hostage. We also briefly met them in the preview of Prometheus #1. He is also most likely the guy who has his face melting off on Gist's AvP cover; note the nasal ridges. Sebela has said that AvP is going to be a "Frankenstein story," so I think the mutated Elden we see in the new previews is the result of extensive genetic engineering with the black goo, rather than the accidental exposure that Fifield underwent.
I, for one, wouldn't mind seeing an Elden figure from NECA. Fingers crossed on that.
A few months ago I almost wrote a post joking that maybe we'd see a return of the bug-men; it looks like I was partially correct!
In all seriousness, Elden is really reminding me of Alpha, one of the villains from the old Men in Black cartoon, who was constantly experimenting on himself with alien anatomy. That doesn't bother me, but he
was my favorite villain on that show.
As far as the Super Predators, I'll hold off judgement on whether those are, in fact, Super Preds, but it wouldn't surprise me. Sebela may have been telling the truth when Rakai asked, but perhaps Super Preds were added after Fox nuked the first scripts. We'll have to see.
Overall, I liked what we saw today. Olivetti's art has a certain stylized appeal, and the mutant Elden definitely meets my criteria for an interesting, bold story.
