->Played by: SylvesterStallone
* AxCrazy: Generally implies in him, specially when he is fighting in battle.
* BadAss: The 80's embleme, and the 2000's resurgence of 80's action type as well.
** BadassGrandpa: In the fourth Movie.
** HeartbrokenBadass: [[spoiler: After Co-Bao's death in the second movie]].
** OneManArmy: '''The''' definitive western example.
** TookALevelInBadass: Rambo does this in between every film (at least if the number of kills he manages to rack up is any indication).
* ButNotTooWhite: In the novels, Rambo was mentioned as being half-Native American.
* DeadpanSnarker: In the third film, Rambo actually manages to crack a few jokes (unlike the other films in the series, where he's dead serious most of the time).
-->''*Trautman and Rambo stand alone against an entire Soviet battalion.*''
-->'''Trautman:''' Any ideas?
-->'''Rambo:''' [[GallowsHumor Well, surrounding them is out.]]
-->'''Trautman:''' [[DudeNotFunny Hell of a time for humor, John.]]
* GoodIsNotNice: No it's not...
* GoodScarsEvilScars: His torso is crisscrossed with scars from where he was cut by knives while a prisoner of war. In the third and fourth movies he also has a burn mark on his cheek from when a Russian interrogator touched him with a red-hot knife in the second film.
** "NOTHING IS OVER! NOTHING!"
** "They would have RAPED her 50 times, and cut all your FUCKIN' HEADS OFF! WHO ARE YOU?! WHOUHANNYOYOU!?"
** "AAAAAAAAAAAARGH !!"
* MaddenIntoMisanthropy: By the fourth movie he has abandoned civilization and humanity almost entirely.
* ManlyTears: At the end of ''First Blood''.
* MoralityPet: Co in the second movie, Trautman in the third movie, and Sarah in the fourth movie.
* RoaringRampageOfRevenge: Rambo goes on one in every film in the franchise.
* SociopathicHero: Especially in the first movie.
* TookALevelInJerkass: In the fourth movie - although he is still one of "the good guys" - he is portrayed as more rude and cynical than in the first three movies.
** Considering everything he's been through up 'til then, it's perfectly understandable that he'd be a left a little bitter.
* WarriorPoet: In the fourth movie.
!!Col. Sam Trautman
->Played by: Richard Crenna (1982-88)
* BadassGrandpa: In The third movie.
* MoralityChain: Usually the only one who can talk Rambo out of his more screwed up moments.
* TheObiWan: He's the man who recruited Rambo into Special Forces and trained him to be a OneManArmy.
* WhatHappenedToTheMouse: In the fourth film, Trautman only appears briefly in a flashback scene. It's never mentioned what happened to the character following ''Rambo III''. This was probably done out of respect for actor Richard Crenna, who passed away in 2003.
!!Sheriff Will Teasle
* BerserkButton: He's always glad to drive drifters to the edge of town closest to their destination, but God help the drifter who dares come back.
* HeroAntagonist: He is performing his duty defending the well being of his town, after all, and still ''genuinely'' believes so as he goes about at the expense of Rambo.
** Subverted somewhat since he's also TheBully to a certain extent, as the reason Rambo goes on his rampage in the first place is because of how he and his deputies mistreated him for no good reason. Played straight only in that ''after'' Rambo goes nuts, he needs to be taken down.
* RetiredBadass: Teasle is the only cop that seems to give thought to tactics and is unimpressed with Rambo's military background. [[MeaningfulBackgroundEven In his office a Silver Star, Purple Heart and ADSC are on display]], revealing that Teasle was not only a soldier but a soldier awarded for extreme valor, presumably in the Korean War.
->Played by: Steven Berkoff
* LargeHam: His fake russian accent is definetly over the top.
!! Col. Zaysen
->Played by: Marc de Jonge
* AwesomeButImpractical: Schoolboy's .50-caliber sniper rifle, while cool, is very impractical for jungle warfare.
* ThereIsNoKillLikeOverkill: Schoolboy's weapon of choice is a Barrett .50 calibur anti-material rifle, which was designed for disabling lightly-armored vehicles. Natrually, the effect such a large round has on a human body is rather horrific.
* TokenGoodTeamMate: The only unambigously kind-hearted and unselfish person in the band of mercenaries rescuing the missionaries.
* WideEyedIdealist: Averted; actually, he's the only idealistic character in the movie that still kicks ass.
->Played by: Maung Maung Khin
->Played by: JulieBenz
* BreakTheCutie: Still feel like helping people now?
* MoralityPet: For Rambo. She successfully guilts him into taking she and her colleagues upriver into Burma.
