Trivia

 * The series tries to keep faithful to the original source, despite the limitations of being made for a children's channel forcing to tone down darker elements in order to fit a TV-PG rating, although it takes some deviations as well.
 * Due to concerns about moral guardians finding it a sensitive and controversial theme on children's television, sexuality issues aren't directly handled by the show, although it's strongly implied that William is gay and has a crush on Rick like his comic counterpart.
 * Debbie and Mark by extension are Japanese Americans.
 * Green Ghost is female.
 * Some plotlines are made up due to being produced while the comic is still in production.
