OK here's a tally on who died in G.I. Joe: The Movie.

First, the stupid COBRA Sob on the turrent. Shoved off the top or strangled or stabbed by Pythona's nails- NEVER shown.

Second, three idiots repairing a jet. Gassed.

Crimson Elite guys- one mummified, 3-4 suffocated with octopus face things, 1 gassed by Pythona, takes off helmet, knocked out?? Killed?

All of the Cobra Command Center guys, courtesy of the gas bombs.

Various Vipers in the attack on the BET, and going to Cobra La.

A few of the Joes, but said most were injured. I think they lived.

Pythona, tossed into crevice, by Jinks.

Nemesis Enforcer into same crevice, by Sergeant Slaughter.

Most of Cobra-La and it's Bug Troops.

DID I MISS ANY?

Actually one of the Joes died in the movie, but since the animators already made Optimus Prime die in the transformers movie they didn't want to make the kids cry, lose faith in their heroes, or stop buying toys. So they edited the ending, I don't know if you can find it anywhere, but I remember a joe dying. It was the one who got hit in the chest with a snake by Serpentor.

Thanks

...was Duke. Yeah, Duke was being phased out of the toyline (or already had been by that point), the Hasbro people didn't good money wasted on advertising a character who had no action figure and the show's writers were tired of fighting to keep Duke in the show when they had Flint on hand. This is why Lt. Falcon was revealed to be Duke's half brother so that Duke's death would inspire Falcon to act like a real soldier (Falcon was originally supposed to be General Hawk's son, which would probably explain the black hair and bird themed codenames). I also hear that GI Joe scribe Larry Hama despised the Duke character was looking for a good excuse to get rid of him.

But Optimus Prime's death went down bad so they said Duke just went into a coma. The coma line is silly though because if you turn off the sound during that scene and you watch the reactions of Falcon, Scarlett and General Hawk, then it's pretty obvious that Duke is dead. Now whenever I look at that scene I want to yell at the TV "Duke took a snake javelin in the friggin' heart! The man is clearly dead!"

Funny thing though, production started first on the GI Joe movie but they ran into a series of production problems, which allowed the Transformers movie got finished first and was released first, proved to be a flop so the originally intended to be theatrically released GI Joe movie was relegated to a direct to video feature. Too bad, 'cause the opening sequence with the Joes fighting the Cobras at the Statue of Liberty would have looked great in a movie theater.

Duke was suppose to die, but was in a coma. Because Serpentor was trying to kill Lt. Falcon (Duke's half-brother). But after the fall of Cobrala, Duke came out of his coma.

Was it ever established that the gas actually kills people or just knocks em out?

Also, I figure the Cobra guard who took off his mask died when Pythona clocked him considering a punch from her caused another Cobra's head to put a huge crack/dent in the steel wall. The force generated by her punch to do that prob shoulda splattered the helmet-less guys head but this is G.I.Joe afterall.
