Calculator

Noah Kuttler a.k.a. the Calculator was a super villain with Obsessive Compulsive Disorder who was continuously defeated by various members of the Justice League. He devised a program on his computer to calculate a hero's powers and/or tactics to create a method from him from ever being affected by them. However, it was ineffective against heroes he has not yet been introduced to yet. Eventually he abandoned his costume for a period of time and became an information broker for supervillains.
