I know this sounds quite ridiculous, but this is a question that has been going through my head for a while, and it's a question regarding if the Sergeant Major has Asperger's Syndrome (a form of high-functioning autism).
On his wiki article, it gradually says on the Character section that he has these things: social problems, difficulty making friends, difficulty interacting with people, problems making eye contact, posture and other social gestures, along with a failure to react "appropriately" to various situations...including restricted interests and high intelligence.
All of these traits I mentioned above are common symptoms of AS, minus his sadistic and mischevious personality. Also, Kururu having an obsession with curry might be included.
Now personally, I'm not an Aspie, but I do share some traits associated with that disorder that I mentioned above.
Aspie here! He might, but attaching aspergers to fictional characters isn't exactly a good idea since that's kind of a tumblrism and you don't want to be lumped in with that crowd. But yes, he might. I do admit i find myself self-identifying with him when watching SF. Now if only I had all of the marketable skills and abilities of these fictional characters i can relate to.
