Niccolo Mazzetti was a 22nd century Human male soldier. Mazzetti served as a member of the MACO contingent assigned to the Columbia (NX-02) by 2156.


Mazzetti was aboard the Columbia when it suffered a crippling attack at the hands of the Romulans in 2156. Captain Erika Hernandez ordered the ship towards a Class M planet at impulse close to c, a decision some of the MACOs felt strongly against.

After the Columbia arrived at the planet later determined to be Erigol, Mazzetti was one of the six MACOs that beamed down to survey the surface, and then was joined by the flight officer away team that made contact with the Caeliar, becoming permanent visitors due to their desire for complete isolation from the universe. When the MACOs decided to rebel and escape their imprisonment on Erigol, Mazzetti and Private Steinhauer subdued the Captain.

Mazzetti then was part of the team to travel to Mantilis and capture the Great Work apparatus, forcing the Caeliar there to reduce the scattering field, allowing Yacavino to contact the Columbia. Pembleton fired on Kiona Thayer, injuring her foot, and Steinhauer held a combat knife to her neck in order to ensure the cooperation of the Caeliar scientists. After Hernandez was freed and allowed to speak to her officers from the Quorum, she insisted that Pembleton, then Steinhauer, kill Thayer so that she did not suffer needlessly; eventually, he and the other MACOs stood down, and Mazzetti found a medkit to stanch her bleeding. However, the extragalactic feedback pulse that disrupted the Great Work caused the planet to explode; the city of Mantilis was able to escape, but millions of Caeliar sacrificed themselves to ensure that the six humans lived to crash land on a unknown planet thousands of years into their past.

After digging themselves from the ice and snow, the group decided to leave behind the crashed Mantilis with the hopes of finding a better location with access to food and water. A week later, Mazzetti was attacked and killed by a predator animal while he was hunting for food. (ST - Destiny novel: Lost Souls)
