Harbinger: "Yeah, little Abomination was born just as an embryo! Wasn't my fault though, that stupid guy Shepard blew up Sovereign and I had to make him. Even better, then comes Shepard and ruined everything, AGAIN! Man I hate that son'of'a'bitch!"
This is the core of a reaper sovereign -ship-. They are what reapers usually look like, the squid/cuttlefish/scorpion/louse duplicates house the actual reapers. It's like having a ship graphed to you basically. -_-
I always wanted to see it completed...I mean, I just think the Reapers weren't thinking when they thought of the design. For some reason, a flying giant human-looking robot in space doesn't seem to scary to me.
I always figured that once it was completed it would take a similar for to that of the other Reapers. It was also hinted at in one of the concepts for the human Reaper, that the front - the face, chest, etc - is actually the back, where the legs would end up being. Don't know if it's true or not, but it might explain why every other Reaper has almost the exact same shape overall.
That would make sense, though it's still odd that it would look human at all if there's a general shape the Reapers have. It's not all organic, and the Reapers wouldn't have to keep to the human form...
Could be a plot hole so players were more disturbed during the battle c:
The first question I had when I saw it was "But why don't Reapers look like other distinct species instead of just one?"
As you said, I think it's something to do with possibly making it more disturbing. If it were just another Reaper, then it wouldn't have had the same effect as seeing humans being turned into goo and made into a human-form Reaper. Probably just a plot hole, yes.
I own the concept book and I must say, I am somewhat confused as to this design. I believe that it originally looked more human but it looked too much like a terminator so they changed some of its features. Unfortunately, no one seemed to consider what people would think about it having three eyes for no reason.
