Talk:Princess Luna/@comment-26973802-20120902000337

I saw Lauren Faust's comment that was mentioned and it also hinted that Nightmare Moon is an embodiment of Luna's jealousy and bitterness mixed with evil magic that seems to be possessing/influencing her, as it says after Luna's transformation she is "no longer present" and "jealousy buried her inside NMM" (although that she is remorseful after her de-transformation suggests she still remembers her time as NMM). Much like Emerald's transformation into a dragon in Sailor Moon R, except Emerald is killed rather than released as Luna was.

And I read somewhere that it has also been hinted that another power helped with her transformation (probably taking advantage of her bitterness and jealousy and magnifying it into the embodiment that is NMM), and that this power might be involved with Discord as well. Maybe it even broke the changelings out of Tartarus (many assume that they came from hell) and is the reason Cerberus escaped the gates, although how the changelings got out unnoticed (as they said no monsters escaped) is a mystery. Perhaps they transformed.
