"Number C39", known as "Chaos Numbers 39" (Ｃ（カオス）Ｎｏ．（ナンバーズ）３９ Kaosu Nanbāzu Sanjūkyū or C（카오스）No.（넘버즈）39 Kaoseu Neombeojeu 39) in Japan and Korea, is a sub-archetype to the "Chaos", "Number", and "Number C" archetypes. All of them are upgraded versions of "Number 39: Utopia", and their effects require a "Utopia" monster to promote the most effective. Also, all of them are from the "Utopia" or "Hope" archetype, thus gaining support from the "ZW -" archetype. They are used by Yuma Tsukumo in the Yu-Gi-Oh! ZEXAL anime and Yu-Gi-Oh! D Team ZEXAL manga.
