(Wellâin most of the AUs/verses I play him in, Prowl was designed and programmed/raised/trained by the Library Monks of Praxus, who were of varying levels of fanaticism and plain eccentricity depending on the âverse. In all cases, Prowl was quite firmly taught that emotions contaminate rational, logical thought, and since he was designed, built, programmed, and (being) trained solely for rational thought, it was of paramount importance that he learn to at the very least control his emotions. Better if he could dismiss them or best of all stop having feelings of his own at all. He only needed to understand how other peoplesâ emotions tainted their processing, not to feel them himself. Needless to say, that pressure made Prowl more than a little weird.)
