Yu-Gi-Oh! 5D's Episode 4: "A Blast From The Past Part 1"
Appearance and PersonalityEdit
Zigzix has a large shock of brown hair that he wears in a style resembling the blade of an axe. He has long bangs and wears amber-tinted glasses.
He gets overenthusiastic when describing things as he tends to do wild gesticulations while doing so. In the Japanese version Rex tolerates his antics, whereas in the English version Rex tends to lose patience with him.
Zigzix is an underling of Goodwin's who heads up R.R.D., the Reactor Research Division for KaibaCorp. He is responsible for ensuring that all of Domino City gets the energy it needs to function. Zigzix was in the process of proposing a new "Ener-D Machine" to Goodwin when his demonstration was interrupted by Goodwin's secretary, Mina Simington.
During the Duel between Yusei and Jack, Zigzix called Goodwin to inform him that the Enerdy Machine was malfunctioning. This appeared to be because of the appearance of the mysterious Red Dragon at the stadium. The Red Dragon's power causes the Ener-D Machine to shut down, shutting down all the power within two blocks of the city. Zigzix manages to restore power within seconds.
During the Fortune Cup, Zigzix and the other Yliaster members conspire to root out Signers in the tournament. Zigzix bugs the stadium with a special device that, when duel energy is released, causes extreme pain to Signers. He is initially dissatisfied with the results, as what he takes to be Luna is not producing any reaction. However, her non-signer brother, Leo, is dueling in her place. Later, Zigzix spots the actual Luna in the audience, and reports his findings back to Goodwin.
Zigzix meets with more success later on in the tournament. When Luna and Akiza's birthmarks glow, Zigzix gets the reading on his D-Sensor. Each time he gets a reading, he informs Goodwin.
When the Crimson Dragon finally appears during Yusei's Duel with Jack at the finale of the Fortune Cup, Goodwin orders Zigzix to turn his machine off, with the risk of a similar incident at Greiger's hometown occurring again.
