Z-Yux

Z-Yux are a gray and red sub-species of Yux who appear Paper Mario: The Thousand-Year Door. Z-Yux are larger and stronger than regular Yux and are used as the security for the X-Naut Fortress on the Moon. Z-Yux are capable of summoning Mini-Z-Yux to protect them with forcefields.

The Z-Yux, along with other Yuxes, are notable in that their beam attacks pierce all Defend Plus and Damage Dodge badges that Mario and his partner have equipped. This means that full damage is taken if no guard is performed, and only one damage is blocked with a regular Guard. The Superguard prevents damage, however.
