Jade's name is a pejorative word for "woman": 1598, William Shakespeare, Much Ado About Nothing:
|“||You always end with a jade’s trick: I know you of old.||”|
This was unintentional, as jade is also a semiprecious gemstone. Her mother's name is also Jaden, which is similar to her name.
Nix is a moon that orbits around Pluto. Similar to Charon's name.
Elektra (130 Elektra) is an asteroid found between Mars and Jupiter. It is named after a woman in Greek mythology, Electra.
Janus is a moon that orbits Saturn. Named after the mythical Janus.
Dag is a crater on the Moon, found in the Lacus Felicitatis.
Marie's drug could be a reference to The Krippen Virus from I Am Legend; the T'langen from Breakdown video games; Superhuman Drug from Bleach or even Nectar from Haze video game. Heck, even Chemical X from the Powerpuff Girls, too.
This is unintentional, as it was supposed to be a drug that turns humans into Pokémon.
