Monstro lies beneath the floor of his Monster Café for most of his waking hours left only to his delusional thoughts and maniacal horror movies. It seems these diabolical vices are all that can tame the horrific beast, which he has become.
Having been raised on a steady diet of late night slasher flicks, Monstro soon developed an insatiable appetite for horror, blood and gore. His psychotic fantasies quickly began to consume the very essence of his being and soon the only happiness he felt in life was found in the grotesque cinematic imagery, which fed his subconscious. As years passed, the old man was no more and Monstro was born.
Seeking refuge from his violent outbursts, Monstro's closest friends and family members sought out professional help where he was thereby subjected to a series of psychological examinations and medical prodding. A controversial medical procedure involving experimental drugs and electro-shock therapy was performed in a last ditched effort to reform him from his pathological and violent tendencies. The results proved to be more disastrous than ever imagined.
Monstro's brain suffered a severe traumatic brain injury in connection with the treatment, which essentially rewired his cerebral functions. As a result, Monstro became somewhat of a savant, a genius if you will, in all things horrific. He quickly memorized every word uttered in every horror film ever made and could recite the entire dialog of any given horror film backwards upon request. He now lives and breathes horror.
His exclusive goal in life is to quench his apparently insatiable appetite for horror, even if it means creating his own horrific reality. He will continue to strive to achieve a gluttonous society of the mad, one customer at a time till death do them part.
