First appearing in "Arkham Asylum: Living Hell", crooked financier Warren White, known as the "Great White Shark" for his ruthlessness, embezzles millions from his company's pension fund and robs virtually all of the company's clients both working class and upper class of their life savings. A smug White manages to avoid prison by transferring his case to Gotham City and successfully pleading insanity to avoid prison and speed up his chances of freedom, a strategy he is all too familiar with and convinced it will work. But the plea incenses the judge hearing his case, who is disgusted with White.
