Norbert Ebersol was a child prodigy with such great mechanical aptitude that he took apart and repaired an alarm clock at age 3. By 10, he had built a small electric automobile; by 13, a relatively complex robotic arm -- both from readily available spare parts. Dropping out of high school due to lack of interest, Ebersol was fired from a number of jobs because of his air of superiority and unorthodox approach to simple tasks. Seeking a challenge, he turned to the planning and execution of technologically assisted crimes. He found that such activities not only stimulated his intellect, but provided him with new raw materials to create even more advanced technological devices.
When most of Earth's heroes, including the Avengers and Fantastic Four, seemingly died battling Onslaught, Ebersol joined forces with Baron Zemo. To gain the trust of the populace, the villains led the world to believe they were new heroes known as the Thunderbolts. During a battle with the Elements of Doom, Techno was cut down. However, his consciousness downloaded into his Tech-Pac and survived, and he re-emerged in a robotic body of his own design.
Zemo's deception ultimately failed. But while his teammates chose to become legitimate heroes, Techno remained a villain. When the Thunderbolts created a base at Mt. Charteris, he stole in and subdued its caretaker, Ogre. He then assumed Ogre's identity and presented himself as such to the Thunderbolts.
