(And no, you don't wanna know what happened to Master Pharaohs 1-89, it's pretty ugly.)Okay, this one is alot of fun to answer!
(Not that she knew he was dead again to begin with, but who's counting?
) And even if there was a chance for Seiya and Usagi, there would be NO WAY for Seiya to physically father any child, due to the fact that he's a she.
A more believable rumor would be if Prince Diamond had fathered Chibiusa (See Diamond kidnapping Sailor Moon in both anime and manga versions of Sailormoon R.), but unless he has time-released sperm, that's not likely either.
Although Hotaru's "affections" can easily be translated into a lesbian sort of way, (Even before being re-raised by Haruka and Michiru) for the most part, they are just best friends.
The Japanese culture usually allows for girls ages 10-16 to go through a "experimental" phase, in which they crush on both guys and girls.
Some outgrow this phase while others may remain either bi or gay. Although they are both Queens of the moon,(Serenity the Queen of the White Moon, the other bitch Queen of the Black) there is NO BLOOD between them.However, the Parallel story albeit short, does give a little more freedom to the possibility of something more between the 2 friends, due to Helios being absent from mention, but it's pretty much set in stone that one day, Chibiusa will meet again with Helios, and the two will most likely live happily ever after. Nehellenia is actually one of several incarnations of a villain known as Chaos.Other "sister" incarnations from Chaos include Queen Metallia, Wiseman, and Master Pharaoh 90. Now this one is definitely THE most annoying of all the Sailormoon rumors out there!Okay, for those who have not yet seen a translated version of the Parallel comic, lemme explain.The manga "Parallel Sailor Moon," was written in 1999.
