Mafioso - actually, Capo Mafioso of NY city. Known for the greasy bag of peppers he constantly eats from. A regular in the series, he never gets the grease on his designer suits. The "Teflon Don" of the series.
Don Pietro is a "behind the scenes" person, and never actually meets Remo face to face. But he does cause trouble for CURE, the USA, Remo, and most peace lovin' folks.
