Number 33: Chronomaly Machu Mech

Number 33: Chronomaly Machu Mech was introduced to the Yu-Gi-Oh! Trading Card Game in the 2012 booster set Return of the Duelist. The card is based on the Chronomaly archetype used by the character Trey in the Yu-Gi-Oh! Zexal anime series, which draws thematic inspiration from ancient civilizations and out-of-place artifacts. As an Xyz Monster, it represents the strategic focus on rank-four plays and battle damage manipulation that characterized the gameplay of the Zexal era.

The design of the card, featuring the intricate, mechanical aesthetics of the Chronomaly line, was realized by the Konami design team to reflect a blend of archaeological motifs and futuristic robotic elements. Upon its release, the Ultimate Rare printing became a sought-after version for collectors due to its embossed foil texture and glossy finish. It remains a notable piece from the early Zexal sets, highlighting the transition period of the game where Xyz summoning became the primary mechanic for competitive play.
