Ello there, just popping in about a thought I had in my head that the titular character of Rogue Trooper comic series has a few similarities to Whiskey. Perhaps he was an inspiration somewhere in Whiskey’s development?
As can be clearly seen, they’re both non-humanly-coloured-skinned soldiers that are helmeted in spite of not wearing a shirt and they’re both manufactured. While Gearbox didn’t make Whiskey blue-skinned himself, they might have just given that to Oscar Mike instead (whose head is clearly blue in concept art).
…but that’s about all I can say about this, since I’ve just happened to hear of the comic series some years back and never read an actual entry in it. I tried to look up the personality of Rogue to see if there were similarities there too, but I’ve failed to find anything. Anyone here’s actually read and wanna chip in?
