Colonnello is the holder of the Blue pacifier. Though he is not part of the original seven Arcobaleno, he attained the blue pacifier after attempting to take Lal's place on the day that they were all turned into babies. He is in charge of the training ground behind Mafia Land and was a former member of the COMSUBIN, thus he is not averse to using heavy artillery, using an anti-tank rifle as his primary weapon.
