We have no direct information regarding Pero Boo, other than that he served under captain Diego Gutiérrez de la Caballería on the Expedition. The last name of Boo may be associated with families in northern Spain. A Pero Bon is mentioned as being in Mexico City, but there is no indication that he is the expeditionary Pero Boo, simply misspelled.
