Every secret crime-fighting organization needs a misunderstood genius to tinker at high-tech gadgets and give them a technological edge. For T.U.F.F., that genius is Keswick. Don't be fooled by his stature or his stutter -- when it comes to inventing cutting-edge anti-D.O.O.M. devices, Keswick is the world's most talented... hmm... mole? No. Prairie dog? Nahhh. Mongoose? Nope.
Come to think of it, nobody's exactly sure what Keswick is, but they know that they can count on him to silence Petropolis's violence with science. If you need his help, look for him in the laboratory. He practically lives there and he's always ready to go!
