Dr. Ogden Wernstrom (voiced by David Herman) is a former student and now rival of Professor Farnsworth, in the field of science. He resents an "A−" grade given for sloppy penmanship by Farnsworth in 2900, and worked for over one hundred years to obtain revenge. Farnsworth usually greets him with an angry shaking fist and a long, drawn-out "Weeeerrnnn-strom!" He often competes against Farnsworth in various competitions, such as the Annual Inventors' Symposium. Despite this, their rivalry appears to have softened over the years, and they have even managed to collaborate with one another every once in a while. Wernstrom also appears to respect some of Farnsworth's decisions if he himself believes them to be right as well, as showed in The Beast with a Billion Backs.
