@pburgund That's a good point. I'd forgotten about Zoroastrianism, although I don't remember if Zoroastrians have such a philosophy concerning the rejection of pleasure, or if they had a savior figure.
In any case, yeah he's BC. I took a look at the raws, and in all the places translated as "savior," Atom's actually saying things like Epi-sama, or Epi-sensei. Definitely Epicurean philosophy then, though more radical than I thought it'd be. Creative license, I guess.
@greatninja3, the translation was, in fact, a little off, just not where I thought it was.
@Say, I don't know if it's my place to suggest corrections to your release, but I just thought I'd share my findings.
