Best anime?

[Chansey]

Sailor Pluto: Froslass.  She's a Japanese female ghost, and they're usually traditionally associated with unrequited love and/or lingering regrets.  She's possibly a reference to Yukina from Yuu Yuu Hakusho, AS IS PLUTO HERSELF.  Don't believe me?  The series are written by ahusband and wife who sometimes easter egg each other's work,  and Setsuna's color scheme is just a darker version of Yukina's; Setsu is another reading of the character for snow, Yuki, so their names are basically a matching pun.  (Think Catty and Kitty.)  And gotta have that ghost type for her.  She's the sailor of the underworld, right..?

Neptune: Gorebyss- a water type that appears lovely, but is really ruthless.  Remember that time when Neptune almost destroyed the world because of emotions..?  She's a female Diamond.  But still popular because she's pretty.  

Uranus: Braviary.  It's a flying type and associated with America;  Uranus's looks are a common anime stereotype of what Americans look like, even though she probably isn't part foreigner.  It's also brave, loyal protective and duty-oriented coughunlikeneptunecough

Saturn: Absol.  A dark type who's feared and loathed because it performs a necessary but inauspicious function trying to save people

Andy the arcade guy: Also Growlithe.  Friendly, loyal and loveable supporting character.  Moon has a great supporting cast imho.
