Charles "Trip" Tucker III, portrayed by Connor Trinneer, is a fictional character in the television series Star Trek: Enterprise.

While a knowledgeable engineer, Tucker can be rash and "illogical", an opinion that early on causes friction between Enterprise's Vulcan science officer, T'Pol, and him.

The attack was made by a prototype weapon that struck from Florida crossing into Venezuela, over the Caribbean Sea, and caused the deaths of 7 million people, including Tucker's sister.

At a crucial point during the Xindi mission, Tucker suffered a potentially fatal injury, and the only way to save his life was to create a clone to harvest needed brain cells.

Tucker admitted to T'Pol's mother he was in love with her daughter during a trip to Vulcan with her after the Xindi mission, during which she decided to marry her fiancé Koss in an arranged marriage.

In the episode "Observer Effect", T'Pol expressed great concern for Tucker, suggesting her feelings for him remained strong, despite her claims to the contrary.

In 2154, during a mission to prevent a Romulan automated marauder from starting a war, Tucker determined that his attraction to T'Pol was negatively affecting his ability to do his job.

During this period, Tucker began experiencing vivid daydreams involving T'Pol, without understanding that she was actually unintentionally communicating with him via mental telepathy when she attempted to meditate.

In the episode "Bound", it was revealed that Tucker and T'Pol had become psychically bonded when they had made love a year earlier, although this link apparently did not manifest itself right away.

The series finale "These Are the Voyages..." revealed that Tucker and T'Pol ended their romantic relationship at some point after the events of "Terra Prime", for reasons as yet unrevealed.

Also, in the Star Trek Enterprise relaunch novels set after "These Are the Voyages...", it was revealed that Trip's death from the explosion was faked so he could join Section 31 to spy on the Romulans, however this has never been solidified as being canon.

At least three offspring have — directly or indirectly — been linked to Tucker: Trip is knowledgeable about the ancient board game Go, and actually has a Go board in his cabin (he is seen playing the game with the title character of the episode "Cogenitor") Trip has a brief romance with princess Kaitamma (played by Padma Lakshmi) from Krios Prime in "Precious Cargo".

In the alternate timeline seen in the episode "Twilight", Tucker becomes captain of Enterprise following the incapacitation of Jonathan Archer and T'Pol's resignation from Starfleet.

The Star Trek: Lower Decks episode "Fissure Quest" depicts a version of T'Pol from a timeline where she was married to Tucker for 63 years.

The details of this plot point are revealed in the novel The Good That Men Do (written, as was Last Full Measure, by Andy Mangels and Michael A. Martin).

In the novel The Romulan War: To Brave the Storm, it is hinted that although Commander Trip Tucker III is officially classified as dead, a small chance existed that he made it out of the escape pod.
