List of unnamed Nausicaans.
22nd century
Nausicaan Canamar prisoner
This Nausicaan was a prisoner aboard an Enolian transport en route to Canamar in 2152. He was an associate of Kuroda Lor-ehn, who was also aboard the transport. He assisted Kuroda in taking over the transport. Afterward, he guarded the prisoners and the transport's captured personnel while Kuroda and Jonathan Archer piloted the ship.
The transport was ultimately intercepted by the crew of Archer and Tucker's ship, Enterprise, who were able to retrieve everyone from the transport with the exception of Kuroda, who perished when the transport was destroyed in orbit of Tamaal. (ENT: "Canamar")
Nausicaan captain
The Nausicaan captain was the CO of a pirate ship that tried to steal the cargo of the ECS Fortunate. During the first confrontation, one of his crewmembers was captured by the Fortunate. The cargo ship under the command of its first officer would get the codes to disable the Nausicaan ships weapons. However after attacking the Nausicaan captain's ship, they found themselves outnumbered by the Nausicaan ships.
Enterprise would intervene in the dispute and try to settle it in a peaceful manner. At first the captain threatened to destroy the cargo ship unless his crewmember was released. He disabled the Fortunate, and the Nausicaans boarded the freighter to retrieve the captive. Captain Jonathan Archer hailed the Nausicaan captain to negotiate a peaceful solution, letting the freighter go in exchange for the hostage. Faced with the superior firepower of Enterprise, the Nausicaan captain agreed to let Archer deliver the prisoner, and he ceased his attack on the cargo ship. (ENT: "Fortunate Son")
Nausicaan prisoner
The Nausicaan prisoner was captured during a confrontation between Nausicaan pirates and the cargo ship ECS Fortunate. Matthew Ryan, the first officer who had assumed command when the captain was injured, beat the Nausicaan until he gave the codes to disable the Nausicaan weapons system. The prisoner was freed after Enterprise intervened between the two parties. (ENT: "Fortunate Son")
Nausicaan pirates
These Nausicaan pirates boarded the cargo ship ECS Fortunate to retrieve a Nausicaan captured in an earlier confrontation between Nausicaan pirates and the cargo ship (ENT: "Fortunate Son")
24th century
Brunt's bodyguards
The Nausicaan bodyguards were employed by liquidator Brunt to enforce the wishes of the Ferengi Commerce Authority. When Rom tried to form a union at Quark's Bar, Brunt had his Nausicaan thugs beat up Quark as an example of what would happen if a union was formed. (DS9: "Bar Association")
Dom-jot players
These three Nausicaans were responsible for the events that necessiated a bionic implanted heart in Jean-Luc Picard in 2327.
After graduating from Starfleet Academy, he was stationed at Starbase Earhart with two of his friends, Cortan Zweller and Marta Batanides. Zweller was cheated at dom-jot by a Nausicaan in the local bar. To get even, he rigged the table. The Nausicaans found out and accused Zweller and Picard of being cowards. A bar fight ensued, and Picard was stabbed in the heart by one of the Nausicaans. In 2369, after being shot in the chest on an away mission, Picard's heart was damaged and he clinically died. Q gave him a chance to change history and avoid the fight, thereby not receive a bionic heart. At first he did, but found out that his life in the alternate timeline was unfulfilling. He had become a lowly astrophysics officer who had no hope of advancement.
Picard summoned Q and begged that he would rather die than live an average life. Q obliged and the fight ensued, with Picard waking up in sickbay in the present and understanding why he was he had become. (TNG: "Tapestry")
Nausicaan on Dessica II
This Nausicaan was a patron of a bar on Dessica II in early 2370. He told Commander William T. Riker, incognito on the planet, a "great" story. Riker said he would remember the story the next time he would be in a knife fight. (TNG: "Gambit, Part I")
Nausicaan trader
This Nausicaan trader entered into a lucrative deal with Quark to buy stolen Denevan crystals. Quark had to devise a way to keep Odo distracted. He set up a romantic evening to celebrate Odo and Kira's one month anniversary of their first date. Odo goes along with Quark even though he knows about the deal. The Nausicaan arrived on the station and brought 200 crystals. (DS9: "The Sound of Her Voice")
