Holder of the Blue pacifier. Colonnello is in charge of the training ground behind Mafia Land and was a former member of the COMSUBIN an elite Italian Navy unit. Colonnello acts like a rival towards Reborn and viceversa they would often consider each other039s attacks weak and then proceeds to attack the other. Though they are rivals he shares many traits with Reborn like being a merciless tutor suddenly taking naps and having a sharp tongue he also finishes his sentences with a quotheyquot at the end. Being a former military member Colonnello is not averse to using heavy artillery he was able to destroy an entire fleet of ships with one antitank rifle. This fits well with his name as it means 039colonel039 in Italian. Also an eagle on top of his head helps him fly to distant places in a short amount of time. It also seems to be in sync with Colonnello: when Colonnello naps the eagle naps. During the Vongola Tournament he becomes Ryohei039s home tutor and actually lives in his house. In the future it is revealed that as an adult Colonnello followed the original seven Arcobaleno on the day that they were turned into babies in an attempt to take Lal039s place. This resulted in him attaining the blue pacifier meant for Lal and consequently turning Lal who was his former instructor in the COMSUBIN into an incomplete Arcobaleno.
