A radscorpion that looks quite intelligent and non-threatening, this arthropod is the result of the Professor's extensive experimentation, which resulted in the creation of a nimble, perceptive creature that's more intelligent than the vast majority of humans in the wasteland. The scorpion is an avid chess player and wears wire-rimmed glasses and communicates with humans by clicking its pincers together.
Defeat the professor's radscorpion in three challenges: The radscorpion can be challenged by talking to the professor and taking three different tests. The Intelligence test, a chess game, is won only by using the "Flying Liver Attack" learnt from Seymour, regardless of stats. The other two tests, which test Perception and Agility, are mere rolls against that attribute. You don't actually win, because the radscorpion always succeeds, but instead you get the experience when you tie.
