Goof: When Baroness unmasks herself, revealing her true appearance, she's seen with blue eyes. But through the rest of the series, her eyes are brown.
Destro: You are my slave, Duke. And soon the whole world will bow to Destro and Cobra.
Cobra Commander: Welcome to the Cobra Arena of Sport, Duke. We are pleased you have agreed to participate in our games. (Laughs)
Duke: I've agreed to nothing, reptile breathe. (Climbing up Cobra flag leading to Destro & Cobra) And the only game that interest me is kicking in your fangs.
Dr. Vandermeer: I can begin construction on the Mass Device at once. But the three substances that power it are extremely rare. We must get them before Cobra does or all is lost.
Cobra Commander: Citizens of the world. We have a power greater than any in the history of man kind. Look and tremble. (Activating the Mass Device which makes the Eiffel Tower disappear) This is but the first in a serious of demonstrations of the awesome power of Cobra. Beg your leaders to surrender to Cobra at once. You have 24 hours. Cobra.
Cobra Commander: You incompetent steel head! Your bumbling has cost me dearly.
Destro: Premature panic is the sign of an immature mind! I have mastered the device.
General Flagg: (To Duke) It looks like your team blew it on the first try.
Major Hooper: The notion of the G.I. Joe team could breech these defenses was totally ludicrous.
(Snake Eyes, Scarlett & Stalker drop out of a panel from the ceiling)
Stalker: You were saying.
(After joining Scarlett & Snake Eyes on the roof)
Scarlett: Thanks for dropping in Stalker. Shall we do out thing.
Stalker: Après vous, ma chère, Scarlett.
Scarlett: (With a southern accent) Why, thank you, sir.
Cobra Commander: We are disappointed. You were expected days ago, Destro.
Destro: (Dropping cloak) The shipment was difficult to assemble and I lost more time climbing to this ridiculously, melodramatic location.
Cobra Commander: I designed the Cobra Temple to guarantee us secrecy and security.
Cloaked man: Oh, great Cobra. We await thy bidding. Give us a sign. (Helpers take off and cloaked man laughs) The superstitious fools didn't even wait for their pay.
(After Duke pushes Scarlett out of the way of Cobra's fire)
Scarlett: Hey! Why didn't you just yell, "Look out?"
Duke: Didn't you read my green sheet? "Man of action."
(After landing her jet)
Duke: Hey, bacteria brain. Come down. Let's discuss your future as a mental patient.
Scarlett: (Opening the hatch) Oh, come on, Duke. Where's you're spirit of adventure? Give a teammate a hand. (Duke helps her down) I missed you, Duke.
Duke: You certainly did. (Holding his thumb and finger close together) By that much.
(After a low flying jet causing Duke, Snake Eyes & Stalker to hit the deck)
Duke: I'm going to kick the mustard out of that crazy hot dog!
