Dwayne Taylor grew up believing his rich parents were gunned down by criminals. Taylor's guardians, the ex-military sergeant Chord (a friend of his father's) and the elderly housekeeper Tai, supported Taylor's vow to make all criminals pay for their actions, helping him create the identity of Night Thrasher.
Taylor trained hard to be a skilled fighter. On his first outing, he met Midnight's Fire and Silhouette. These two superhumans were taking out criminals by gaining their confidence and then busting them. Giving his name as Night Thrasher, Taylor joined them on their crusade. One night, while Silhouette was infiltrating a gunrunning operation, the police accidentally came upon them. Scared that the police were fixing to shoot his sister, Midnight's Fire started to throw a blade at them. Taylor stopped him before he had a chance to throw it, and a gun battle erupted. Silhouette was hit and badly injured in the spine. Taylor, who had fallen in love with Silhouette, was heartbroken, as was Midnight's Fire. Midnight's Fire swore to get revenge on Taylor someday. Taylor left them, believing that Silhouette was dead.
Realizing that he needed more of an edge, Taylor trained even harder. Using his parent's Taylor Foundation, Taylor had Chord provide him with a state-of-the-art headquarters, training facilities, and computer support systems. He also had developed specialized armor and weaponry. Taylor then decided to create a special team so he would have some backup. He recruited several young heroes and formed the New Warriors.
Shortly after they formed the team, Midnight's Fire made an appearance and tried to frame Taylor with the murder of two policemen. In a final battle with Midnight's Fire, Taylor overcame his fear of his nemesis and beat him in a battle. Taylor then discovered that Silhouette was still alive but crippled. She renounced her brother's actions, turning him in to the police and joining Taylor in the New Warriors.
After the Warriors thwarted a plot by the criminal scientists of A.I.M., Taylor discovered a link between A.I.M.'s benefactors and the Taylor Foundation. With some investigation, he discovered dozens of illegal operations and shady business practices performed by the Foundation, linking them with criminal industrialist Gideon and the Japanese Yakuza syndicate, among others. Taylor used the Warriors to seek out the truth in confronting the Yakuza, but the team balked at making a deal with criminals. Taylor refused to budge, and the argument led him to quit the New Warriors.
Taylor was then approached by the criminal team Folding Circle, of which Midnight's Fire was a part, since they promised to lead him to the truth of his past. In doing so, it was revealed that Taylor's father, while in Vietnam, was captured by Tai, who was a powerful sorcerer guarding an ancient temple. Tai had coerced Taylor's father and others in his military unit, including Chord, to have children with the women of the temple, in order that their children would later be sacrificed in the temple's mystic well of dimensional energies and thereby give Tai even greater power. Chord and Taylor's father tried to thwart this plot, and Chord was thus mystically ensorcelled to kill Taylor's parents. The Folding Circle was comprised of the children of Tai's prophecy, but it was assembling its members too early for Tai's wishes. The New Warriors, investigating Night Thrasher's activities, tracked the Circle to the Vietnamese temple, where they joined Folding Circle in a climatic battle with Tai. Ultimately, Tai was seemingly slain by the very energies she tried to master.
Taylor rejoined the New Warriors and served with them for a long tenure. He left the team eventually, rededicating himself to his role as chairman of the Taylor Foundation, although he would team up with them when the need arose. Later, Taylor decided to give up adventuring altogether, becoming a full-time director of the Taylor Foundation. He believed that true battles for justice would be fought in the boardrooms. He moved to the Seattle branch of the Foundation, seemingly disbanding the New Warriors.
Over time, however, the New Warriors reassembled without Taylor's help. Even so, as the Warriors continued to use equipment and facilities associated with the Taylor Foundation, he was able to monitor the new version of the team. He even rejoined them briefly against the assassin Junzo Muto and agents of the Hand.
More recently, the Taylor Foundation suffered a massive downfall when its funding of cancer research banked on the efforts of Zachary Smith. Smith’s cure was revealed to be nothing more than his mutant son’s subconscious help. The Foundation’s stock tanked and Smith abandoned his son, but Dwayne Taylor stepped in to adopt the young mutant, now Microbe. However, it would require more creative solutions to save the Foundation. Night Thrasher made a deal with shady television executive Ashley Brothers to avoid bankruptcy, but this also forced the New Warriors into a unique re-branding as a reality-TV show. Hoping to make the best of the situation, the team hit the road to become heroes for the common man throughout small-town America.
The Warriors enjoyed mixed success and popularity, but the show was officially canceled and bankruptcy proceedings were initiated. Even so, the Warriors were able to return and continue their reality-TV efforts. However, when they hoped to boost their ratings by apprehending a quartet of villains holed up in Stamford, Connecticut, tragedy struck. During the battle, Nitro used his power to cause a massive explosion. It killed Night Thrasher, the New Warriors, and killed almost everyone in the vicinity.
