And You Thought It Would Fail: Marvel had supreme difficulty finding someone to write the title. No one wanted to since comics based on toys were notorious short runners. Larry Hama has said he only got the job because everyone else said no and because he was desperate for a writing assignment. Of course, under Hama's writing, the comic was a huge success that lasted over a decade.
Ensemble Darkhorse: Due to Loads and Loads of Characters, this trope is inevitable. Snake-Eyes, for example, is extremely popular among fans. For a later part of the Marvel Comics run, the cover title actually included "Featuring Snake-Eyes."
Executive Meddling: Comic writer Larry Hama absolutely hated the entire concept of Cobra-La from the movie, and flatly refused to write so much as a single word about it. He only relented almost 25 years later, penning a Cobra-La comic that was packaged with the redesigned Cobra-La figures. It was even advertised on the package as "The first Cobra-La comic written by Larry Hama."
Besides, his Iron Grenadier outfit compensates for the original one.
Harsher in Hindsight: In an early issue the Joes go against a Middle-Eastern dictator that commanded an army of radical zealots and was backed by a Terror group. Twenty years later America went to war against several Middle-East countries ruled by dictators backed by zealots with ties to terrorist groups.
Cobra Commander's class warfare rhetoric about the destruction of the American Dream, the corruption of the United States by corporations, and the fact they're patriots for wanting to take back the government by destroying it sounds eerily similar to a lot of later feelings from Americans in the 21st century from Occupy Wallstreet to the Tea Party. It also makes him sometimes come off as Unintentionally Sympathetic.
I Am Not Shazam: G.I. Joe is the name of the organization, not the name of any one character.
There is actually a character named G.I. Joe in the series: Joseph B. Colton, the legendary soldier for whom the organization was named—his name was Joe, and he was a GI (traditionally, from World War II). For the record, he's implied to be the very same gentleman from the orignal 12-inch action figure line, famed for his full beard and kung fu grip.
Moment of Awesome: Snake-Eyes is one of these personified, including breaking into Destro's castle to save Scarlett and actually taking on Storm Shadow and his ninjas with little weapons, and breaking free during a Cobra torture session, and going upstairs to rescue the people who were supposed to rescue him. In Snake-Eyes-Land, prisoner saves you!
Technology Marches On: Back in 1984, Ace's brag about the Skystriker having 92K of memory was impressive. Today, even the cheapest "kiddie" MP3 player made has at least 256MB; meanwhile, a modern F-22 has 300,000 times more computer capacity.
