"Number C39", known as "Chaos Numbers 39" (CNo.39 Kaosu Nanbāzu Sanjūkyū or CNo.39 Kaoseu Neombeojeu 39, in Japan and Korea respectively), is a sub-archetype to the "Chaos", "Number", and "Number C" archetypes. All of them are upgraded versions of "Number 39: Utopia" and requires either "Number 39" itself or an "Utopia" monster to be more effective. Since all of them are from the "Utopia" or "Utopic" archetype, they also gain support from the "ZW -", "ZS -" and "Zexal" archetypes. They are used by Yuma Tsukumo in the Yu-Gi-Oh! ZEXAL anime and Yu-Gi-Oh! D Team ZEXAL manga.
