Western Animation / G.I. Joe: Sigma 6
aka: GI Joe Sigma Six


"Striking from the shadows, a ruthless organization named COBRA has returned to unleash an endless army of robotic troops and massive machines on the world. Our only hope, a group of highly skilled young operatives thrown together to save the planet. With time running out, they must become the super secret team known only as Sigma 6."

Initially a Hasbro toyline re-imagining characters from one of the company's popular 1980s franchises, GI Joe Sigma 6 is also an animated series (2005-2007), produced by the Japanese animation studio GONZO. Ironically, this description fits another series (Transformers Cybertron) to a T.

A continuation (sort) of the two direct-to-video GI Joe CGI movies, Spy Troops and Valor vs. Venom, Sigma 6 has Cobra Commander broken out from prison and the Joes forced to evacuate their base. Traveling in their mobile command center, the R.O.C.C. and equipped with Hi-Tech's Sigma suits, the Joes renew their battle to protect the world from Cobra.

The show ran for two full seasons on 4Kids TV, and is later re-aired on The Hub.


  • Adaptation Distillation: The series draws from the original mythos, along with bits and peices of other, more recent works.
  • Animesque: Inverted, it's a genuine anime based on a American toyline.
  • Ascended Extra: High Tech used to be one of the less important Joes. Here, he often outpaces Duke and most of the other Joes in screen time. It helps that pretty much everyone is using a lot of super technology (more so than usual, anyway) and this gives him a lot of chances to flaunt his specialty. Destro specifically considers High Tech his "Sigma 6 Counterpart", giving him one of the show's primary rivalries.
  • Bloodless Carnage
  • By-the-Book Cop: Heavy Duty refers to Scarlett as such.
  • Conspicuous CG: It's a trademark of GONZO after all.
  • Continuity Reboot: While implied to take place after the direct-to-video films Spy Troops and Valor vs. Venom, at least in some capacity, the series for the most part comes off as being a completely new continuity.
  • Continuity Snarl: The first season established the series as a sequel to the CGI G.I. Joe specials (Spy Troops and Valor vs. Venom) produced by Reel FX. The biggest evidence of this is the fact that General Hawk is still in the hospital recovering from the "Venomization" process he suffered during the events of Valor vs. Venom. However, a later Compilation Movie of the first five episodes (called "First Strike") added a scene that established that the Joe team from Sigma 6 were not the same Joes from the CGI specials, but new members who inherited the codenames of their predecessors 20 years after the original members retired. Somehow, most of the Cobras also got identical successors as well and they managed to get a new Storm Shadow who just happens to be the rival of the new Snake-Eyes.
  • Cool Car: Lot's and lot's and... did I mention there are a lot?
  • Cool vs. Awesome: Snake Eyes vs Storm Shadow, or maybe it's the other way around.
  • Do Not Adjust Your Set: Cobra Commander does this in the show's final episodes.
  • Family-Friendly Firearms: Not really shocking, it's G.I. Joe.
    • Though Buzzer's "Laser Chainsaw" is really pushing it.
  • Family-Unfriendly Violence: Cobra is nowhere near as ineffective as he was in the past. In fact, he's down right creepy sometimes.
  • Five-Episode Pilot
  • Gotta Catch 'Em All: The energy rocks called "Power Stones" that Sigma 6 and Cobra end up fighting over.
  • Grand Finale
  • Immune to Bullets: Much of Cobra's tech.
  • Instant Awesome, Just Add Mecha: Both Cobra and the Sigma team jump on the Mecha-bandwagon.
  • Karma Houdini: Cobra Commander and Firefly end up escaping in the finale "Assault", while the other Cobra members are captured.
  • Mecha-Mooks: The B.A.T.s
  • Never Say "Die"
  • Oh, Crap!: Poor Spud really screwed things up with his playful hacking.
  • Pineapple Surprise: In Valor vs Venom, Snake Eyes pulls the pins on every grenade on Storm Shadow's bandolier to escape him. Storm Shadow survives by tossing the belt before it's too late.
  • Polar Bears and Penguins: Actually manages to get this one correct. When the Terrordrome Project is activated, the scenes of the two devices in the north and south poles have quick shot of polar bears in the north and a penguin in the south, as it should be.
  • Powered Armor: The Sigma suits.
  • Theme Tune Roll Call
  • The Voiceless: Snake-Eyes
  • This Is the Final Battle: In the episode "Duel", Cobra Commander says to Duke that it will be their last battle when they're about to fight in the Cobra Coliseum.
  • Took a Level in Badass: Cobra Commander, this time around. He now resembles more of a dictator than a coward!
