->''"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 Creator/{{Hasbro}} toyline re-imagining characters from [[WesternAnimation/GIJoeARealAmericanHero 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 Creator/{{GONZO}}. Ironically, this description fits another series (''Anime/TransformersCybertron'') 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 [[PoweredArmor Sigma suits]], the Joes renew their battle to protect the world from Cobra.

The show ran for two full seasons on [[FourKidsEntertainment 4Kids TV]], and is currently re-airing on TheHub.

!!Tropes:

* AdaptationDistillation: 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.
* AscendedExtra: 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.
* BloodlessCarnage
* ByTheBookCop: Heavy Duty refers to Scarlett as such.
* ConspicuousCG: It's a trademark of GONZO after all.
* ContinuityReboot
* ContinuitySnarl: 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 CompilationMovie 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.
* CoolCar: Lot's and lot's and... did I mention there are a lot?
* CoolVersusAwesome: Snake Eyes vs Storm Shadow, or maybe it's the other way around.
* DoNotAdjustYourSet: Cobra Commander does this in the show's final episodes.
* FamilyFriendlyFirearms: Not really shocking, it's G.I. Joe.
** Though Buzzer's "Laser Chainsaw" is really pushing it.
* FamilyUnfriendlyViolence: Cobra is nowhere near as ineffective as he was in the past. In fact, he's down right creepy sometimes.
* FiveEpisodePilot
* GottaCatchEmAll: The energy rocks called "Power Stones" that Sigma 6 and Cobra end up fighting over.
* GrandFinale
* ImmuneToBullets: Much of Cobra's tech.
* InstantAwesomeJustAddMecha: Both Cobra and the Sigma team jump on the Mecha-bandwagon.
* InstantAwesomeJustAddNinja: As soon as Snake Eyes shows up, you know things are gonna get awesome.
* KarmaHoudini: Cobra Commander ends up escaping in the finale "Assault".
* MechaMooks: The B.A.T.s
* NeverSayDie
* OhCrap: Poor Spud really screwed things up with his [[PlayfulHacker playful hacking]].
* PoweredArmor: The Sigma suits.
* ThemeTuneRollCall
* TheVoiceless: Snake-Eyes
* TookALevelInBadass: Cobra Commander, this time around. He now resembles more of a dictator than a coward!
