Simon is quite an unusual grem, spending most of his time cooped up in his lab. He takes his work very seriously being a former college professor, though he is no longer qualified for such a title.  Despite his grisly and absent-minded appearance, he's quite friendly, often willing to do demenstrations for local events. His personality is a  mixture of NileRed and StyroPyro, with a voice similar to Airy (HfjONE). 

His favorite bfdi character is golfball.
