First Appearance: (Jensen) Ghost Rider II#4 (February, 1974); (Roulette) Ghost Rider II#5 (April, 1974)

Powers/Abilities: Roulette could open portals in space, through which he could hurl fireballs at his foes. He proved immune to the hellfire of the Ghost Rider, but his own fireballs could drop Ghost Rider. He could switch to and from his original human form at will. He received his power directly from Mephisto, and it could be increased as needed.

History:
(Werewolf by Night: Blood Hunt#1 (fb) - BTS) - As a fallback from promoting stock-car racing Jensen ran the Wild Dino Adventure Park in the Arizona Desert outside the Hopi Tribal Lands.

   Jensen sometimes took his nephew Trevor to eat donuts at the raceway and ice cream after going to the casino. When Trevor was 10 Dude gifted him a switchblade, which had saved Dude from some ugly situations in the past. Trevor believed Dude was the only relative that really cared about him.

(Ghost Rider II#5 (fb)) - Dude Jensen was a big-shot stock-car promoter. He attempted to make out big at a Las Vegas casino, but ended up losing terribly. After he'd lost the twenty thousand in credit extended to him, the heads of the casino learned that he had lied about his finances, and that his bank account was virtually empty. The casino owners had Jensen take out into the desert and dumped into a water-filled quarry, "with a belly full of lead ulcers."

   Mephisto chose Jensen to become his pawn, and offered him a return to life and the ability to gain vengeance on his killers in exchange for his soul and the promise to serve him.

(Ghost Rider II#4) - Jensen hired John Blaze to ride in a demolition derby, and then sent an assassin to take him out. Blaze, of course, turned into the Ghost Rider and stopped the assassin. Roxanne Simpson overheard Jensen discussing the assassination, but was discovered and taken hostage by Jensen.

(Ghost Rider II#5) - Jensen revealed himself to be Roulette and attacked the Ghost Rider as he was driving across the desert. He then began to cast fireballs down upon the city of Las Vegas. Blaze followed Roulette's trail back to his castle and attacked him, but Roulette laughed off his hellfire. Roulette floored the Ghost Rider with a fireball of his own, and then called to Mephisto for the additional power to finish him off. Mephisto agreed, but as he granted him the power, Ghost Rider poured his own energy into Roulette as well. The power overloaded Roulette and he imploded, leaving only ashes.

(Werewolf by Night: Blood Hunt#1) - Trevor, Sam and six of their friends summoned the spirit of Duke Jenson at the Wild Dino Adventure Park. Jensen recognized where he was and that his nephew was behind it. Dude tricked Trevor to allow him to use his body as a conduit and managed to possess him with his demonic Roulette form. He tested his powers by trying to burn Trevor's friends with Hellfire, but only managed to kill Carson because Trevor's body was too weak. Jake Gomez, who was friends with Trevor and Sam, was hiding out at the park and saw what was going on. Dude burned another of Trevor's friends before Gomez distracted him long enough to give Trevor's friends a chance to scatter. Roulette absorbed more power from his possessed nephew while looking for his friends at the park. He activated the animatronic dinosaurs, roller coasters and lights at the park and soon found Gomez and Sam. He hit the former hard while the latter escaped once again. Roulette soon realized that he was unable to leave the park and was sure that one of Trevor's friends knew how to break him out. He found one of Trevor's friends hiding out in a shooting booth and burned him alive after learning from him that Sam owned the spellbook they used to summon Roulette back to Earth. While Gomez, now transformed into his werewolf form, took out three vampires, Sam ran right into the arms of Trevor, still possessed by Roulette, who demanded from her to free him from the park. Moments later the out of control Werewolf (Gomez) jumped through Roulette's demonic spirit form and slaughtered Trevor. Without his nephew Duke was a mere ghost again that could not interact with the real world. He remained stuck at the park.
