Their D-Pad is also gold plated and shaped like an X.

ZEXAL Field
ZEXAL III grants Yuma and Astral to utilize a new ability called "ZEXAL Field" (ゼアル・フィールド Zearu Fīrudo) as a way to counter the negative effects that the Barian Field would usually have on their bodies..

Synopsis
During Yuma's Duel against Mr. Heartland, the bonds between Yuma and Astral became stronger because of Yuma's happiness with reuniting with his partner. This resulted in the creation of a new ZEXAL form, ZEXAL III, allowing Yuma to draw "ZS - Banish Sage". Yuma uses ZEXAL III's power of "ZEXAL Field" to counter Heartland's Barian Field. He then used the effect of "Banish Sage" in conjunction with the banishing effect of "Galaxy-Eyes Photon Dragon" to banish all of Heartland's "Infection Bug Tokens", then attacked directly with "Galaxy-Eyes" to win the Duel. After the duel, Fake "Numbers one through four transformed into black flames and engulfed Heartland, even as he begged mercy to Vector.
