Little is known about Noah Kuttler a.k.a. the Calculator. There are indications of him being active as a supervillain as early as 1975, fighting Starman Mikaal Tomas, but his main career has lasted for about ten years. Often dismissed because of his goofy looks, a keyboard strapped to his chest and an LCD visor on his forehead, it is often forgotten that his technology (of unknown origin) was extraordinary. By punching numbers on his keypad, he was capable of generating almost any energy construct, much like a Green Lantern Ring. The computer in his costume could calculate anything, anticipate any attack, and conclude how to strike at opponents. However, the Calculator had to encounter his opponent at least once before having sufficient info to use. Calculator first made a name attacking members of the JLA – Atom, Black Canary, Green Arrow, Elongated Man, and Hawkman. The villain allowed himself to be captured once by all of them, then being able to defeat them. He would have won had he not been outsmarted by Batman.
Later, Calculator fought Air Wave, Blue Beetle, and Hero Hotline, but was defeated every time. Finally, he decided to ditch his costumed identity. Inspired by stories about “the Oracle”, an information source to superheroes, he found a new career. His computer and skill with information makes him a perfect info broker for supervillains, Charging $ 1,000 per question, the Calculator constantly stands in contact with criminals who need to learn hard-to-get facts about their victims or enemies.
