Played by: Kim CattrallA Vulcan helm officer.
- Bothering by the Book
- Green Blooded Space Babe
- Jedi Truth
- The Mole
- Remember the New Guy
- Sucksessor: A variation, since aside from the whole bit about being a traitor and a murderer she's actually an extremely competent officer.
- Suspiciously Similar Substitute: For Lt. Saavik from films II-IV, plus Commander Xon from the unmade Star Trek: Phase II TV series, in that they're both Vulcans who are set up to succeed Spock.
- Tempting Fate: She suggests serving Romulan Ale during the meal with the Klingons, which given the underlying tensions between the two peoples and the extreme strength of Romulan Ale, goes over about as well as you'd expect. Of course, this is part of a Xanatos Gambit to make it later look like Kirk attacked Gorkon's ship in a moment of drunken rage.
Played by: Christopher PlummerA Klingon officer who is opposed to peace with the Federation.
- Affably Evil: He is a Klingon officer vehemently against Starfleet and the architect of a conspiracy, but he respects Kirk for his valor.
- Bald of Evil: He was supposed to have long hair, but Christopher Plummer had liked his bald appearance, so Chang became bald..
- Big Bad: He fills the role of the film's main bad guy, but he's really part of a Big Bad Ensemble including Admiral Cartwright, Colonel West and the Romulan Ambassador.
- Chewing the Scenery: It's not enough that he's already a Large Ham. When reciting William Shakespeare he proceeds to shout it at the top of his lungs and spin in his captain's chair."CRY HAVOC! And let slip the dogs of war!"
- Cultured Warrior
- Evil Counterpart: A bald starship officer who quotes Shakespeare? Never heard that one before.
- Eyepatch of Power: Bolted onto his skull, no less.
- Face Death with Dignity: Upon seeing the modified torpedo approaching his ship, he quietly says "To be, or not to be..."
- Incoming Ham: He has an impossible to detect ship. Rather than simply unload on the Enterprise he decides to open a channel and announce himself.
- Invisibility Flicker
- I Shall Taunt YouI can see you, Kirk... Can you see me?
- Large Ham: He quotes Shakespeare as a battle taunt.
- Obi-Wan Moment: When he realizes that Enterprise's torpedo is homing in on his ship, he simply waits for it while quoting Shakespeare.
- Well-Intentioned Extremist: The Star Trek: Klingon Academy video game gives a better, more detailed look at his motives; basically, he's an honorable conservative who genuinely fears Gorkon's moderate policies will lead their race to their doom.
- Worthy Opponent: Despite all his efforts to have Kirk framed and killed, he makes it clear that he holds him in the highest regards as a skilled and accomplished warrior. And when he gets the chance to fight Kirk in an actual battle, he finds this much better than if everything had gone according to the original plan.
Played by: David WarnerThe intellectual and soft-spoken chancellor of the Klingons, who seeks peace with the Federation.
- Famous Last Words: To Captain Kirk. "Don't let it end this way, Captain..."
- Honor Before Reason: Many of his fellow Klingons were against his decision to present an olive branch to the Federation. It cost him his life.
- Our Presidents Are Different: Chancellor Target and Chancellor Personable.
- Reasonable Authority Figure: While his hand was largely forced by the explosion of Praxis, Klingon Academy shows that he had wanted peace with the Federation before he originally became Chancellor.
- X Meets Y: Gorkon is Abraham Lincoln meets Mikhail Gorbachev as a Klingon.
Played by: Rosanna DeSotoGorkon's daughter, who succeeds him as the Klingons' chancellor.
- Jerkass Has a Point: While her delivery is much harsher than neccesary (part of the discussion in general breaking down), her criticisms of the Federation during dinner are spot-on. Other than the president and a small minority of Starfleet officers the leadership of this supposedly multi-ethnic Federation (as shown in this movie) might as well be a human empire.
- Reasonable Authority Figure: Refuses to invade the Federation or cancel the peace talks in response to her father's assassination, considering it sufficient to put the alleged assassins on trial.
- Shut Up, Chekhov! / What the Hell, Hero?: However, everything is on her terms, and refuses to bend her knee at the Federation.Azetbur: "Inalienable human rights." Why the very name is racist.
Played by: Paul RossilliA high-ranking Klingon officer.
- Blood Knight: Tries to persuade Azetbur to declare war against the Federation.
- Undying Loyalty: He is dedicated to Gorkon. He is also just as loyal to Azetbur and as much as he really wants a war to avenge his beloved Chancellor, he respects her authority enough to back down and keep his Blood Knight tendencies in check.
Played by: Michael DornA Klingon attorney who defends Kirk and McCoy at their trial.
- Identical Grandfather: Confirmed by Word of God to be the grandfather of his namesake in Star Trek: The Next Generation. This, incidentally, makes Dorn one of only two people — the other being Majel Barrett — to appear on-screen in TOS, TNG and DS9-related works.
- Only Sane Man: During the trial, he is one of the true reasonable Klingons and does his best to defend his clients.
- Reasonable Authority Figure: He retains the rank of Colonel and is a level-headed attorney whose ego is not attached to the trial unlike his fellow comrades.
- Spanner in the Works: He persuades the judge at Kirk and McCoy's trial to sentence them to exile on Rura Penthe rather than giving them the death penalty. It's subtle, but you can see that Chang is not pleased by this development, and it allows Kirk to escape and foil the conspiracy.
Played by: W. Morgan SheppardThe officer in charge of the Rura Penthe penal colony.
- Cool and Unusual Punishment: Literally; his favored method of executing rebellious or lazy prisoners is to have them stripped naked and thrown out onto the surface of Rura Penthe, where they freeze to death in less time than it takes for him to give his big speech to the new arrivals. It's implied that he makes a point of making a demonstration of this every time new inmates arrive.
- Death by Adaptation:
- The film's novelization shows that Chang intends to have him executed for allowing Kirk and McCoy to escape, though leaves it ambiguous as to whether or not Chang actually gets around to putting this in motion before he himself is killed. In the movie he just angrily hangs up on him.
- His counterpart in the Star Trek (2009) timeline ends up predeceasing his prime reality counterpart by at least three decades, dying during Nero's escape from Rura Penthe.
- Just Between You and Me: Decides that since he's about to kill Kirk and McCoy, he can afford to give away the identity of the mastermind behind the conspiracy. In a subversion, he actually gets prevented from doing this by the Enterprise crew, who beam their crew-mates aboard before he can spill the beans.
