And yet Rambo's two sidekicks are basically expys of the friends he was confirmed to have lost in the movies.
Turbo is based on Delmar (Rambo's black friend who dies prior to the opening scene of First Blood) and Katt, well... she's blatantly a take on Co Bao from FBpII.)
Also that last line wasn't always followed; the episode that has Rambo reunite with one of his *other* friends from the past (a pathfinder type of vet nicknamed "Wrong Way") clearly has a flashback to Vietnam or some sort of military operation in a rainy jungle.
This show was basically a One Man GI Joe series. It's a serviceable action cartoon if you know *nothing* of the source material but holy fuck. Growing up watching this and then watching the movies, especially First Blood...
That was a trip, I tell you.
