Takeshi Matsuya (松矢 隆) was placed as a student at Saint Simon's Academy, a private special education elementary school, shortly after losing the use of his legs in the same accident that killed both of his parents. Taki, as he came to be called, held deep feelings of resentment toward his parents for abandoning him, which further isolated him from children of his own age.
A computer genius and novice inventor, Taki occupied his time creating small but fantastic electronic devices. During this period of isolation, Taki first manifested his mutant ability to technoform materials to function to his specifications, even to the point of being contrary to the laws of nature and science. Shortly after first manifesting this ability, Taki was befriended by Arthur "Artie" Maddicks and "Leech" the Morlock, two mutant wards of the mutant group X-Factor, placed at the Academy to receive a mainstream education.
