Abstract:A subobjects structure of the category OHgr-FSet of OHgr-fuzzy sets over a complete MV-algebra 
$$Omega = left( {L,Lambda , vee , otimes , to } right)$$
is investigated, where an OHgr-fuzzy set is a pair A = (A, delta) such that A is a set and delta: A × A rarr OHgr is a special map. Special subobjects (called complete) of an OHgr-fuzzy set A which can be identified with some characteristic morphismsA rarr OHgr* = (L × L, mgr) are then investigated. It is proved that some truth-valued morphisms 
$$_Omega :Omega ^ * to Omega ^ * , cap _Omega , cup _Omega :Omega ^ * times Omega ^ * to Omega ^ * $$
are characteristic morphisms of complete subobjects.
Keywords:fuzzy set over MV-algebra  complete subobjects  subobjects classification
