Scientist
Perceptor

146
While it is obvious to even the most casual observer that Perceptor is unrivaled in metallurgy, electrical engineering, and concomitant subfields of Cybertronian physiology, these abilities only constitute an inaccurate approximation of his unquenchable thirst for knowledge; to wit: his facility with all manners of scientific inquiry and analysis asymptotically approaches infinity.
Through dedicated empirical analysis subject to many rounds of peer review, Perceptor has acknowledged that there is an inverse relationship between his near-continual use of scientific terminology and the listener's ability or willingness to understand him.
