Leopold "Butters" Stotch is a student at South Park Elementary School.
He is naive, optimstic, and guillible. He was born on the island of
Kaua'i on September 11. He is the only child of Stephen and Linda
Stotch, from whom he perpetually faces the looming prospect of being
grounded.
Butters has many alter egos.
Marjorine
Butters fakes his own death and poses as a new female student,
Marjorine, so he can infiltrate a slumber party hosted by classmate
Heidi Turner and steal a mystical relic that allows them to see the
future.
Mantequilla
Butters gets lost while playing "Texans vs. Mexicans" with his
friends. As he tries to find his way back, a couple in a passing car
takes him to their home, believing him to be a Mexican immigrant
named Mantequilla.
Hawaiian Butters
Butters has reached the "Age of Panua", an anger-filled
coming-of-age for those of Hawaiian descent. Keeping with tradition,
Butters' parents send him on a pilgrimage to his native land.
Professor Chaos
Professor Chaos is Butters Stotch's villainous alter-ego. Born from
a life of dejection, he vows to bring chaos to the world that has
shunned him time and time again.
