Laszlo was born on August 1960 along with Lena. He was a turd among the children due to his undiagnosed psychopathy. He never has any empathy for anyone, because his genetics are rigged towards rules that suit him instead of the other people.
Laszlo left the house in his young adulthood and became the secret adviser for the Corinthos mob in its early days. He still avoids both the prison and paying taxes, as he still lives in a tax haven named Shelbyville.
He is still single and has a mistress named Califia, who bore him a daughter named Lassie in 1999.
