I don't think that's him. While it sounds a bit like him in the recording, their faces look different. Gator's nose is more angular, while this guy has more of a snub nose. Gator has slanted eyes, this guy has rounder eyes. Gator has a very high hairline, this guy's hairline is more normal. Gator is a manlet, this guy is not. Gator is fat and stocky, this guy is just fat (different frame).
That's just my opinion though based on these few images we have. If you can engage him in conversation directly (and act normal so he doesn't know you're from the farms if indeed that guy is him) and record it, we could at least confirm or rule out the voice.
I would advise against sperging about Ralph and the Killstream etc unless you're sure this is Gator. If it's just some dude working in a store, he might think you're crazy and bar you from the shop.
