Ax-Crazy: Paticularly in the first movie where Rambo mistakes a kid out hunting game for one of the officers pursuing him and Rambo has to force himself to let the kid go. Col. Trautman himself lampshades this during the climax where he accuses Rambo of having wanted to initiate a fight from the beginning.
Badass: The 80's emblem, and the 2000's resurgence of 80's action type as well.
The Dreaded: In the first film. Most of the police and national guardsmen who are hunting Rambo are scared shitless of him.
Good Scars, Evil Scars: 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.
Took a Level in Badass: Rambo does this in between every film (at least if the number of kills he manages to rack up is any indication).
Took a Level in Jerkass: 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.
Weapon of Choice: Whatever he can get his hands on, although some have become synonymous with the character
What Happened to the Mouse?: 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.
Played by: Julia Nickson
Spared by the Adaptation: It's possible for Co to survive in the NES Rambo game, and if she does the ending will imply that Rambo returned to America and took Co with him.
Benevolent Boss: He genuinely cares for his deputy, heck, Galt's death is one of the main reasons why he chases after John.
Berserk Button: 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.
Hero Antagonist: 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 since he's also The Bully 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.
Jerkass: Even though he believes he's doing his duty, he does seem to enjoy throwing his weight around.
Knight Templar: Feels he has his town's best interest at heart when he uses heavy-handed protocol against vagrants.
There Is No Kill Like Overkill: 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.
Token Good Team Mate: The only unambigously kind-hearted and unselfish person in the band of mercenaries rescuing the missionaries.
