Rudger's actions make him one of the more prominent antagonists of Yu-Gi-Oh 5Ds, being responsible for the Zero Reverse disaster which created Satelite, and his various attempts on the Signers do to his own abilities made him the most recurring Dark Signer challengers as the Shadow Drones under his command used some of his cards as well.
He says that they have been waiting for 5,000 years in order to carry out revenge against the Signers and expects for this fierce battle to be most "exceptional". He wears black robes accented with red stripes which corresponds to his Earthbound Immortal, as his Mark of the Shadows represents the Spider. It was also revealed that he was the original Signer with the Head Mark of the Dragon on his left arm, though he replaced it with a metal arm since prior to becoming a Dark Signer.
Known as Roman Goodwin in the English version, he is a primary antagonist in the first season (second season English release) of the TV anime: Yu-Gi-Oh! 5D's.
Roman and Rex, while working for R.R.D.. Roman Goodwin, is the older brother of Rex Goodwin. Just like his brother, Roman served as an assistant to Professor Fudo, while working in R.R.D..
Dr. Fudo was bent on canceling the Enerdy project due to the natural disasters occurring in Domino City as a result of using the system. But wanting to continue the research, Roman researched occurrences similar to what was happening in Domino City. He then came across the Nazca Lines. Once at the site of the Nazca Lines, a mysterious man who belonged to the Yliaster group spoke to him. The man told Roman that he is destined to activate the Enerdy Reactor and tells him to look into the light of the Enerdy Reactor. After returning to the facility and Roman looked into the light of the Enerdy Reactor. He then saw the battle between the Crimson Dragon and the Earthbound Immortals. He was then appointed head researcher of the project.
Roman obtains "Stardust Dragon", "Red Dragon Archfiend", "Black Rose Dragon" and the "Ancient Fairy Dragon" cards, which are the keys to activate the Enerdy Reactor's control units. Dr. Fudo managed to take three of the cards and flee, leaving behind "Ancient Fairy Dragon" when he was wounded by Roman's henchmen.
The Spider Dark mark appears on Roman's arm, where it struggles with the Dragon Head birthmark for control of his body. Nearly succumbed to the power of the Dark Signers, Roman decides to leave his Mark of the Dragon to destiny by tearing his left arm off and placing it in a preservation canister (Which was removed from dub, and still had his hand without being ripped off completely). He then gives Rex the canister telling him to gather the Signers and someday defeat him. After that he activates and overloads the Enerdy Reactor which ultimately lead to the Zero Reverse, killing himself and subsequently allowing the first Earthbound Immortal released, Uru, to revive him as a Dark Signer.
Signers and Dark Signers battle
After the Fortune Cup ended, Roman possessed Grady and Trudge, in order to test the Signers, Yusei Fudo and Jack Atlas. Roman as a Dark When the Signers along with Mina, Leo and Trudge venture to Satellite and are meet-up with Martha, Roman appears imposing a Duel. Jack wants to, but is stopped by Yusei as he tells him that it's too dangerous to duel here, especially if a geoglyph appears. Jack is instructed to take Martha and the kids somewhere safe, while Yusei, accompanied by Akiza, faces Roman in a Shadow Duel another location.
However, three of the children decide to watch the Duel. As the Duel unfolds, Yusei and Akiza notice two kids near the flames caused by the geoglyph and wonder how they got in when they are not signers. As Roman prepares to Summon his "Earthbound Immortal", "Uru", Yusei and Akiza fear that once it's Summoned it could use the kids' souls as sacrifices. Luckily, Jack appears and uses his birthmark to stop the kids from being sacrificed. Yusei eventually manages to gain the upper hand in the Duel. As a final insult to Yusei, Roman uses evil magic to flee and force Rally to take his place. Rally manages to destroy Uru, but doing so apparently costs him his life.
Roman, along with the other Dark Signers later appear before their rivals, the Signers to begin their final battle. For the mean while each of his comrades are currently waiting at each of the control units of the Original Enerdy Reactor with the purpose of dueling against their correspondent Signer rival. As for Roman, he awaits within the place where the system itself resides. After Devack's defeat at the hands of Luna and Leo, he kills Greiger in order to make him into a Dark Signer by pushing him over the Original Enerdy Reactor. Roman blows up the bridge Kalin's defeat, Roman's mark seems to be causing him anguish as it escalates up his arm. But he is confronted by Rex Goodwin, who Duels him. Rex loses on purpose in order to be reborn as a Dark Signer like his brother.
Yusei and his friends enter the crater in the B.A.D., where they confront Roman. Although Yusei wins, Roman proceeds to tell Yusei that things have not finished yet, as an the King of the Underworld will soon be born. Before Roman dissolves, he detonates a bomb in his left arm, blowing up the bridge and sending Yusei falling into the depths of the Enerdy Reactor.
Roman is the fourth Dark Signer to be defeated. When Rex is finally defeated and the King of the Underworld is destroyed, Roman and Rex are the only Dark Signers to not return to life.
Roman's "Spider" Deck is an Insect-type deck with his strategy focused on changing the Battle Possition of monsters on the field and taking control of them with Earthbound God Uru. His Deck also contained support cards specific to Earthbound Gods (Earthbound Immortals in the localization hence the names) such as "Earthbound Whirlwind and "Roar of the Earthbound". The Videogames expand on his deck to include more than what was seen in his duel with Yusei.
Geoglyth & Patron God
Kiryu is the Dark Signer who represents the Earthbound God (Jibakushin) Uru. A spider-like diety of the netherworld that like regular spiders posses eight legs
- Rudger's Geoglyth is widely believed to be a spider, but is also believed by some to actually mean to resemble an Ant as the most most common argument to see the geoglyth in question as a spider is because it has eight legs while Ants only have six, however the geoglyth in question's thin middle, and ant-like mouth.
- Like the rest of the Jibakushin, Uru possesses a secondary colour alongside its mostly black body, the colour in question being Red could be a nod, and/or foreshadowing to Rudger's original status as a Signer.
- Rudger's age being around his late twenties to early thirties at the time of his death makes him the eldest Signer by a significant age margin as Yusei (the next oldest by confirmation with Jack and Aki seeming to have been born shortly after Zero Reverse) being a mere infant at the time of Rudger's death. It is possible that the Crimson Dragon had originally intended such a vast age range to be so that Rudger could act as a mentor towards the far younger signers when the time came but because of Rudger's corruption and death this did not happen.
- Uru (or Uro) are people who live in man-made totora islets in Lake Titicaca, where is it said is the origin of the Inca Empire.
- As well Uru is also a Quechuan word, meaning "spider."
- Uru could represent Roman as being the "boss" of the Dark Signers and his mark as being the Old Ener-D reactor itself while the other Dark Signer marks (except the whale and condor) are the control units that the Ener-D reactor relies on.
