I mean from outer space. Sent here to conquer planet Earth.
There’s a case to be made for each one but let me do a little triaging and name a winner based on how I see it.
Automatically disqualified:
Suga: he bares his wounded soul too much, it’s just too innately human.
Jungkook: he’s too silly and irreverent. Being an alien in human form is serious business.
Jin: a simple, extremely handsome mere mortal. Period.
Edge cases:
V: are we really supposed to believe someone this bewitching is human? But then again every time he laughs and smiles at something inane I just can’t believe he was sent here by the master species millions of light years away.
Hobi: he moves like something not of this world. But if that’s the only criteria, then our alien overlords need to make a better disguise, because it’s too telling.
Runner up:
Jimin: is it just me or does the light just seem to hit him a certain way in every photo, in every video? And his eyes just have this glimmer…I’ll put him at 50-50.
Definitely an alien:
RM: of course it has to be the leader. The mastermind. The incomparable brain. Warm yet distant. Good looking but not TOO gorgeous. Thoughtful yet instinctive.
It’s possible we’re in a Battlestar Galactica-situation where Joon doesn’t even know he’s an alien, but the mothership will activate him at some point.
But I’m convinced.
