Lightman is Totally an Alien

Fun fact! Lightman absolutely isn't an alien! There's no way. And yet, this rumor persists to the present day.
  A/n: Gee, I wonder why Ruby Gray is so fussy about this.
  It's not like we don't have aliens around. There's not a lot, because our atmosphere doesn't always mesh well with how they think, but there's a reasonable number of extraterrestrials on the planet. Known extraterrestrials, no less.
  Yet somehow people assume that Lightman is an alien. Because of one single interview he did that was clearly trying to avoid the question that had been asked, because reporters have not got enough boundaries.
  The internet ran with it from there, and now we have the legend that is the alien Lightman tale.
  First, there is the assumption that he comes from a place well beyond the known areas or planets that we know have aliens. The kind of thing where "of course you've never heard of it, but trust me, it exists." The common assumption is that he was sent here as a prince or otherwise scion of royalty, sent along as a baby to avoid a coup. This is also used to explain why no one else came with him, because they were either supposedly dead or fighting for their lives.
  He's meant to have a royal guard of some kind, but they died along the way for some weird reason, probably because only Lightman is powerful enough to adapt to how our planet works or some nonsense like that.
  The most common reasoning used for him being an alien is that while we have light-based Enhanced around, he is by far the most powerful.
