Rex Goodwin

Rex was a very manipulative man, who usually spoke in a calm, friendly demeanor, and appeared very respectful to others, particularly Jack and referred to him politely as King-sama. However he wasn't above being physical and direct when he grabbed Mina by the jaw after not wanting to listen to her excuse about Jack.[3] He believed that the separation of the New Domino City and the Satellite was necessary, as they complimented each other well and promoted growth. He sinisterly claimed that he would sacrifice one side for the other, in order to preserve the peace. He was quick to take action in turmoil, as even after Grieger attempted to kill him, he rallied to the audience of the Fortune Cup that he would protect them all as that was his duty as Director, even at the cost of his own life. During the Fortune Cup, he was utterly determined to expose the Signers via his varying agents that he had placed in the Tournament; and set up various plots in order to do so. He was also incredibly knowledgeable in the Legend of the People of the Stars and information about the Dark Signers.

He had great love for his brother, often calling him "nii-san" in the Japanese version, and promised him he'd take his arm with the birthmark and gather the Signers to stop him and the Dark Signers in the future. After sending the Signers into the Satellite, he revealed to his brother that he had found a new possibility; to gain the powers of both a Signer and a Dark Signer in order to become the Ultimate God to destroy and recreate the world in order to stop the cycle of conflicts every 5,000 years.

Rex Goodwin was a tall pale-skinned man, with long grey hair that reached into his lower back, with one section of it tied into a ponytail. He wore a dark grey suit and pants, over a collared shirt that featured the Condor geoglyph emblazoned on it. He lost his left arm in an accident, and replaced it with an artificial robotic one, with a built-in Duel Disk. Goodwin wears a long-sleeved suit and white gloves at all times so his mechanical arm goes unnoticed. When he was much younger, his hair was brown and shorter, and he typically wore a lab coat.
