Final Fantasy III Characters

Render of the four main characters Luneth, Ingus, Arc, and Refia, for the DS remake of Final Fantasy III

Final Fantasy III focuses around four orphans from the remote village of Ur, each of them starting off as Freelancers. The Nintendo DS version of the game individualized the party members, giving them unique appearances (designed by Akihiko Yoshida), backstories, personalities and names: Luneth (ルーネス Rūnesu), who symbolizes courage, an adventurous orphan boy raised in the village of Ur; Arc (アルクゥ Arukū), who symbolizes kindness, Luneth's childhood best friend and a timid yet intelligent young man; Refia (レフィア), who symbolizes affection, a girl raised in the village of Kazus who tires of her father's blacksmith training and often runs away from home; and Ingus (イングス Ingusu), who symbolizes determination, a loyal soldier serving the King of Sasune, with a (mutual) soft spot for the princess Sara.
Though Xande (ザンデ Zande) is the one they have to stop for the most of the game, he is eventually revealed to be merely a pawn of the Cloud of Darkness (暗闇の雲 Kurayami no Kumo), a malevolent and vicious deity who wishes to push the world into a state of chaos and destruction by upsetting the balance between light and darkness, allowing the Void to consume the world. Appearing in a female-like form, she refers to herself in first-person plurals. Although she initially defeats the Warriors of the Light, they are resurrected with Unei and Doga's help, and, with help from the Dark Warriors, they defeat the Cloud of Darkness.
The Onion Knight (seemingly based on both Luneth and the unnamed lead character of the Famicom version, with an alternate costume based on Luneth) and the Cloud of Darkness are the respective hero and villainess representing Final Fantasy III in Dissidia: Final Fantasy, where they are voiced by Jun Fukuyama and Masako Ikeda respectively in the Japanese version, and by Aaron Spann and Laura Bailey, respectively, in English. In the game, the Onion Knight is a child prodigy sort who accompanies Terra Branford in their search for their crystals. But from getting his after battling the Cloud of Darkness, he learns to feel from his heart as he and Cloud Strife help Terra get her crystal from Kefka Palazzo.
The Cloud of Darkness is referenced in Ivalice-set titles Final Fantasy XII, Final Fantasy Tactics Advance and Final Fantasy Tactics A2: Grimoire of the Rift as a summonable entity (known as an "Esper" in the first, a "Totema" in the second and a "Scion" in the third) by the name of Famfrit, also known as "the Darkening Cloud".
