Zaat

The film begins with mad scientist Dr. Kurt Leopold in his lab, where he has lived alone for about 20 years (it is revealed later in the film that he graduated cum laude from MIT in 1934). He is contemplating his former colleagues' derision for his "formula", which is described as "<big>Z_aA_t</big>" (read ''Z-sub-A, A-sub-T'', but which he simply calls "Zaat"). This compound, it is later explained, can transform humans into sea creature hybrids and "mutate all sea life". He injects himself with the serum and immerses himself in a tank connected to an array of equipment, emerging as a fish-like monster.
