Bretón began his career in the children's area "La casa de Pequita", driving Anita Ontiveros in the mid-1970s.
At the end of 1979, Bretón worked as editor of the newly opened Teleantillas, channel 2, traveling the following year to study a bachelor's degree on Television at the Complutense University of Madrid, Spain.
Upon his return in 1995, Bretón took over as director of the program "Nuria en el 9", who coincidentally had worked in "La casa de Pequita".
Since 2004 until his death in 2009, Bretón created, produced, wrote and directed "Relatos de Micky Bretón", after being a producer of several programs, including "Nadie es perfecto" and "Noche de luz".
Breton was murdered in a motel (cabaña) on November 1, 2009 in the Dominican Republic.
