Allen Sarlo (born January 9, 1958) is an American surfer, most prominently known as one of the original members of the Z-Boys surf and skateboarding team.

The aggressive and slashing style of surfing he pioneered during the 1970's earned him the nickname "Wave Killer".

Sarlo began surfing at the age of 5[3] and by 13, he had won his first competition, the boys' division of an amateur event in El Segundo, California.

In 1977, Sarlo joined the professional international circuit after taking first place in the West Coast Junior Championships.

The film documents his adolescence as part of the Zephyr and his athletically intense surfing style.
