Despite the unfortunate name, Dr. Blunder is highly skilled and quite competent in his field ... the problem is no one really knows what field that is.
Sometimes an adept scientist, other times an expert psychologist, occasionally showing skills in fields ranging from surgery to carpentry and more. It has been unclear from the start how he became the head of the Gardner Hill Insane Asylum, apart from his own assurances that this title was passed along to him via Dr. Degrade himself. Rest assured he can always be found lurking in the background watching the inmates intently, and occasionally running "experiments" on them for his personal research.
