Even IMF Agents couldn't handle the missions on their own from time to time. Sometimes they require the expertise of a trusted ally...most of the time.
Mission Commander Swanbeck: What? To go to bed with a man and lie to him? She's a woman, she's got all the training she needs.
- Chuck Cunningham Syndrome: Disappears between the second and third films with no explanation, though the gap between them makes this more plausible than in a typical Bond movie.note
- Classy Cat-Burglar: She's an international jewel thief. Downplayed, in that she's recruited for her past relationships with Ambrose rather than her skills as a thief.
- Feed the Mole: On the receiving end when Ambrose imitates Hunt.
- Human Shield: A variation. She deliberately contaminates herself with the last shot of Chimera, knowing that Ambrose won't kill her until it finishes multiplying inside her, then uses this to her advantage to help Hunt escape.
- Put on a Bus: Though she's set up to be a permanent love interest and addition, she doesn't return for the sequel.
- Typhoid Mary: Averted, though Ambrose uses the term to describe his plan to cause a global outbreak of Chimera so he can get rich selling the vaccine. It will kill her, but not before she becomes a vector to spread the disease to countless others.
Julia Anne "Jules" Meade-Hunt
Ethan's girlfriend and future wife.
- Action Survivor: She has no military background at all but can handle herself admirably under pressure. In the third film, after Ethan is incapicitated, she manages to shoot two bad guys dead despite just learning how to use a gun barely a minute ago before proceeding to revive Ethan. In Fallout, she instantly realizes the moment she saw Ethan and his team in the vicinity that something is definitely wrong. Her suspicion is proven right when she comes across Luther trying to dismantle a nuclear bomb and immediately offers him a helping hand despite having no experience in bomb defusion. When Ethan apologizes for putting her in the line of danger time and time again, she actually thanks him for turning her into this trope, saying that he helped her into becoming someone she didn't know she was capable of being.
- CPR: Clean, Pretty, Reliable: In M:I-III, Julia has to do this to Ethan.
- Distressed Damsel: She is kidnapped by Davian's men so Ethan can reveal the location of the "Rabbit's Foot".
- 11th-Hour Ranger: In Fallout, after Luther said that he can't defuse a nuclear bomb fast enough without a helping hand, Julia shows up and immediately offers to help him in whichever way she could.
- Faking The Death: Knowing that as long as Julia is close to him she could never be safe, Ethan has her faking the death, both to protect her and to give himself an excuse to go on a vendetta against her supposed 'killers' and get himself into a Russian prison as part of a mission in Ghost Protocol. The gambit is so convincing, it fooled even a highly trained agent like Brandt, who really believes she's dead until Ethan reveals the truth.
- Happily Married: In Fallout, just not with Ethan.
- Sequel Non-Entity: Played with in Ghost Protocol. Julia is nowhere to be seen, and a throwaway line indicates that she and Ethan suffered an Offscreen Breakup, the way sequels often awkwardly do to romantic leads despite having spent so much attention and development on them. It then actually gets a surprising callback gag, when it turns out Julia actually died and Brandt was partially responsible, so she hasn't been just thrown away with one line. Then it turns out she's alive and Ethan set up a whole deception so that she can be safe, as she can't be married to him. She appears at the end after all.
- Something Only They Would Say: When Musgrave puts Julia on the phone to talk to Ethan, Ethan asks her to tell him the name of the lake where they met, to verify her identity. She correctly answers, "Wanaka".
- Took a Level in Badass: She had to defend herself against Davian's men while Ethan was in a comatose state and killed Musgrave on the way.
- Played By: Miraj GrbićAppearances: Ghost Protocol
A funny Russian guy whom Ethan insisted on rescuing from a Russian prison and cousin to Russian criminal "The Fog".
- Affably Evil: A jolly Russkie fellow and a friend to Ethan but he also has ties with the criminal underworld.
- Chekhov's Gunman: During the opening prison breakout, Ethan simply refuses to leave without him to Benji's confusion. After the two break out, Ethan tranquilizes him and sends him to another van, and he disappears for much of the film. He shows up just before the finale as Ethan's contact to his cousin "The Fog" a Russian arms dealer who can provide information about how one could hack an old Soviet satellite to transmit the nuclear launch codes and the Indian billionaire who possesses it, allowing Ethan to deduce where he could find Hendricks after he disappears in Dubai.
- Funny Foreigner: The guy is the Butt-Monkey for most of the opening sequence. He panics easily, gets punched by a prisoner after Ethan dodged it, falls flat on his ass after descending down a rope, and gets tranquilizes by Ethan.
- Motor Mouth: It only takes to put him into sleep to keep his mouth wide shut.
- Played By: Vladimir MashkovAppearances: Ghost Protocol
A SVR (Foreign Intelligence Service of the Russian Federation) agent who pursuits Ethan after he is framed for the destruction of Kremlin.
- Enemy Mine: He makes a deal with the criminal "The Fog" to track down Ethan, even though it was a Batman Gambit made by Ethan to proof his innocence.
- Friendly Enemy: Once Ethan proves himself innocent by stopping the nuclear launch and eliminates Cobalt, Sidorov finally gives up his pursuit and even offers to take the badly injured Ethan to a hospital.
- Insistent Terminology: He keeps calling Ethan "Team Leader" as that was what Hendricks called him through his communications during the Kremlin infiltration.
- Inspector Javert: The first one that is not a member of the IMF that takes a distrust on Ethan Hunt. The guy would just not give up pursuing Ethan, which is justified because for all he know, Ethan is the one responsible for possibly the most devastating terrorist attack in Russian history, not to mention the stolen nuclear launch device. Ethan uses this to his advantage in the climax, where he allows the arms dealer The Fog to tell Sidorov that Ethan is in Mumbai so he can follow him there, where he could lead him to Kurt Hendricks, the real mastermind behind the attack.
- Nice Job Breaking It, Hero!: Him showing up in Dubai and attempting to arrest Ethan foils his plan to apprehend Wistorm!Hendricks, leaving Hendricks to get away without a trace, which almost dooms the entire world to a new World War had Ethan did not have a backup plan in place.
A mysterious and manipulative woman working inside The Syndicate. Her agenda is... difficult to figure out.
- Action Girl: The greatest of all six movies and the closest that Ethan has to an equal.
- Anti-Heroine: Repeatedly betrays Ethan but also consistently comes to his aid. She's committed to her job, but also wants out of the spy life. Her reasons are more complex than just to do the right thing.
- Badass Biker: Her vehicle of choice is motorcycles, and she is just as adept at it as Ethan.
- Big "NO!": During the climax in Fallout, she lets out a few while she is tied up when seeing Benji is about to walk into Lane's trap, though can't fully due to being gagged.
- Bound and Gagged: In Fallout Ilsa is captured by Lane, tied to a chair and gagged. However she is able to free herself, overpower Lane and save Benji from being hanged.
- Chuck Cunningham Syndrome: Ironically averted; despite Rogue Nation giving the character a happy ending, she came back in Fallout.
- Damsel out of Distress: In Fallout is bound and gagged by Lane. When Benji enters Lane starts hanging them, however Isla smashes the chair she is tied to, defeats Lane and saves Benji.
- Does Not Like Shoes: She really doesn't seem to like wearing shoes, using any opportunity to ditch them and go barefoot.
- Double Reverse Quadruple Agent: Rogue Nation pingpongs her loyalties practically from scene to scene.
- Femme Fatale: A mysterious dark woman that switches from side to side depending on the situation.
- Fiery Redhead: She kicks the damn out of everyone, and has dark red hair and freckles.
- Good vs. Good: What her relationship with Ethan usually boils down to. Despite her flip-flopping agendas, she's ultimately never working for villainous gains. It's just that what she often requires to free herself from MI6 usually runs in opposition of what Ethan needs.
- Happy Ending Override: In Rogue Nation, she was able to get a clean start and left the movie free. She shows up in Fallout revealing that between the movies, she was hunted as MI-6 considered her a danger. She spends Fallout trying to prove her loyalty.
- The Mole: For Lane? For Ethan? For someone else? Who knows. Eventually revealed to be with the British Intelligence.
- Ms. Fanservice: Wears a dress that frequently billows open to show her legs to the Opera, shows up in a also very revealing bikini, and swims in her panties later on. See below for more fanservicey tropes. Downplayed in Fallout, in which she hardly bares skin at all.
- Murderous Thighs: Her specialty.
- Promoted to Love Interest: Fallout's ending hints she become this to Ethan.
- Second Love: In Fallout, Luther tells her point-blank that Ethan has only ever had serious feelings for two women in his life — his now ex-wife Julianote , and Ilsa herselfnote .
- She-Fu: Her signature attack is to launch herself onto the shoulders of an opponent for a variety of ways to dispatch them.
- She's Got Legs: And the camera sure likes to show them off.
- Toplessness from the Back: Briefly seen when Benji was talking to a recent rescued Ethan and preparing to run away.
- Unresolved Sexual Tension: Has a definite attraction to Ethan (and vice versa) but their missions constantly get in the way. Ilsa even asks Ethan to run away with her in lieu of stopping Solomon Lane in Rogue Nation.
- Wild Card: Again, shifting allegiances and whatnot.
Julias new husband and a fellow medical philanthropist.
- Nice Guy: The man is practically a saint. Julia loves him very much and Ethan seems to approve of him as well and wish them both much happiness.
- Second Love: For Julia, after she and Ethan break up.
- Understanding Boyfriend: He knows Ethan is Julia's old flame and that they are hiding things on purpose but doesn't pry and even tries to have them all talk to catch up with each other.
