Along with Rey Galang, Christopher "Topher" Ricketts was a founder and a major contributor behind the Bakbakan organization. He gained exposure in 1986 from a project called "Masters of Arnis", which also featured Rey Galang, Antonio Diego and Edgar Sulite. They toured Sydney and Melbourne, Australia giving seminars on the Filipino Martial Arts, particularly those taught as the Bakbakan curriculum. This international exposure for Bakbakan triggered several articles in mainstream martial arts magazines. Since then, he had collaborated with Antonio Diego on a book about the art of one of his primary teachers, Antonio "Tatang" Ilustrisimo.

Largusa’s genius became apparent when he systemized and broke-down Villabrille’s fighting techniques, and put into place theories and philosophies that comprise the art. He explains that Villabrille “was greatest influence in my life because he opened my eyes to many things, allowing me to observe, analyze and finally modify things for the better.” It is for this reason that the art is known today as the Villabrille-Largusa Kali System. As the years passed, he saw the need to perpetuate Villabrille’s teachings and to promote a part of the Filipino heritage.
