Wise Steiner, a thief hailing from the planet Norma, serves as the younger counterpart of Professor Weisz from the year X442. His life fractured when his mother succumbed to a mysterious illness later traced to Drakken Joe’s life-support device siphoning her vitality, igniting his vengeful drive. A used robot became his sole companion in the aftermath, mentoring him in the Ether Gear "Machina Maker" over three grueling years before his uncontrolled power destroyed it, cementing his isolation and sharpening his cynical self-reliance. Joining Sibir’s criminal gang, he forged a bond with its leader until a stolen pendant—a keepsake from his mother—shattered their alliance. Expelled after accusing Sibir of theft, he retaliated by stealing a case that revealed Pino, an android, instead of riches. This act entangled him with Shiki Granbell and Rebecca Bluegarden, who sought his older self. Bargaining for ownership of their ship, he restructured it with Machina Maker, revealing both his mechanical genius and self-serving pragmatism. Gradually, loyalty eclipsed his mercenary instincts: he repaired the damaged Happy, orchestrated Rebecca’s rescue on Guilst, and outmaneuvered foes like Laguna Husert through tactical analysis. Machina Maker grants him dominion over machinery, repurposing debris into weapons or upgrading tech. Collaborating with Hermit, he forged the "Arsenal" exosuit, augmenting combat prowess with techniques like Vise Cannon and Drum Buster. His Overdrive form elevated these abilities, enabling intricate mechanical manipulation. A pivotal encounter with Professor Weisz—his alternate-timeline elder self—exposed divergent paths, the elder’s tempered wisdom contrasting with his own brashness. Though prone to leering at crewmates and scheming pranks like coaxing Homura into a bunny costume, he balanced irreverence with empathy, rescuing Sister Ivry or fretting over Rebecca’s safety. Beyond combat, his strategic intellect and piloting skills proved vital in conflicts against Baku, Killer, and during the Belial Gore arc. In Universe Zero, subtle shifts hinted at deeper emotional growth, particularly a tentative romantic pursuit of Hermit. Surviving timeline resets via Etherion, he retained memories of erased worlds, leveraging this knowledge against threats like the Chronophage. By unraveling its link to Rebecca’s temporal abilities, he aided in pacifying the entity, stabilizing planets and solidifying his evolution from rogue to indispensable guardian of the Edens Zero crew.
