I cannot be the only who legit gets so pissed when solarball fans call "X" Hades as that is Greek version of Pluto's name, like I get wanting to staying through to the proposed names by Nesviry for this planet but couldn't you pick Liber or Mephitis? They are also proposed names for the planet.
It's a stupid thing to get mad about, but I refuse to accept it as canon until there is an episode in which Planet X is called Hades.
