[[folder:Sigma 6]]
!!Duke
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/duke_38.jpg]]
-> '''Voiced By:''' David Wills, Greg Abbey

* AFatherToHisMen: Like most incarnations of the character, he is something of a father figure to the other Joes.
* AllAmericanFace: He's a good guy who fights for America.
* TheHero: He tends to get most of the good toys, too.
* IndyPloy: Duke is quite fond of these when he's out in the field, usually in some kind of deep trouble.
* JackOfAllStats: And because of this, he is able to fit in no matter what the team configuration for the current mission is.
* TheRival: To Cobra Commander.

!!Scarlett
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/scarlett_8.jpg]]
-> '''Voiced By:''' Amy Birnbaum, Creator/VeronicaTaylor

* ActionGirl: Though she specializes in counter-intelligence, she's no slouch when the going gets rough.
* UsefulNotes/AmericanAccents: Dixie.
* DeadpanSnarker: Usually in response to stressful matters and circumtances, like Tunnel Rat for example.
* ImprobableAimingSkills: She can hit anything she aims at.
* TheLancer: When she's around, she's usually Duke's second in-command.
* TheRival: To the Baroness.
* TheStraightAndArrowPath: She uses arrows as her weapons.

!!Snake-Eyes
[[quoteright:298:https://static.tvtropes.org/pmwiki/pub/images/snake_eyes_8.jpg]]

* AbsurdlySharpBlade: Nothing new to the character.
* TheBigGuy: Shares this with Heavy Duty, at least in function.
* DualWielding: He uses two katanas.
* McNinja: As is tradition. He and Storm Shadow trained under the same Ninja Master as youths.
* MightyWhitey: He's a Caucasian ninja.
* ParryingBullets: Also nothing new. His swords can block lasers, of course.
* TheRival: To Storm Shadow. Probably the most pronounced of the rivalries at that.
* ScarsAreForever: As shown in a flashback, he and Storm Shadow both have scars received in the past when they failed to properly execute a difficult technique. His is near his eye, which is normally covered up by his visor.
* TheSpeechless: As always, he doesn't speak. Lt. Stone infers that he can't in the second season premiere.
* StealthHiBye: Has a tendency to vanish without notice when the others are talking to him.
* SwordAndGun: Has no problem [[NeverBringAGunToAKnifeFight bringing guns to a knife fight]] and [[NeverBringAKnifeToAGunFight vice versa]].

!!Heavy Duty
[[quoteright:266:https://static.tvtropes.org/pmwiki/pub/images/heavy_duty.gif]]
-> '''Voiced By:''' F.B. Owens

* {{BFG}}: The biggest, which he is able to use because of his hefty size.
* TheBigGuy: Shared with Snake-Eyes, literally and in function.
* OneHeadTaller: Than pretty much every one else. Not only is he the biggest, but he's also the tallest, too. Only Destro can match his height.
* PowerFist: Uses and favors these when his {{BFG}} isn't an option.
* TheRival: To Destro, physically.
* ScaryBlackMan: Only to his enemies or when angered. Otherwise, he's pretty [[BoisterousBruiser affable]].
* SuperStrength: His natural size accounts for this especially when augmented by the aforementioned {{Power Fist}}s.
* ThoseTwoGuys: With Tunnel Rat.

!!Tunnel Rat
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/tunnelrats6.jpg]]
-> '''Voiced By:''' Creator/MichaelSinterniklaas, Sebastian Arcellus

* AirventPassageway: As the group's infiltration expert, he tends to favor these or their equivalents a lot.
* UsefulNotes/AmericanAccents: A Noo Yawk one.
* BigEater: Despite his rather lanky build, he has a voracious appetite. He still can't best Heavy Duty in this department, though.
* DeadpanSnarker: Mainly does this with regards to the current situation or Heavy Duty.
* DoggedNiceGuy: Has a crush on Scarlett, which she doesn't reciprocate.
* EyesAlwaysShut: With a couple of [[{{Irony}} "blink and you'll miss it"]] exceptions.
* HiddenDepths: He's a lot more observant and knowledgeable than he may seem and even has some minor hacking skills to his name. Biggest example of this is how he was able to find secret tunnels in the tomb he was taken to initiate his Ninja training, and correctly used math to puzzle out where they lead throughout the tomb, even though the tunnels themselves weren't listed on the map he was given.
* TheNapoleon: Though he's not ''that'' short, he's still the shortest out of everyone sans the two girls, Scarlett and Jinx.
* PluckyComicRelief: He actually tends to bring out the best (or at least most funniest) in characters he interacts because of this.
* StuffBlowingUp: Favors this tactic as the group's demolitions expert.
* TunnelKing: Most at home in the dirt. He also has the uncanny ability to find hidden passageways, sometimes even ones that the resident Ninja overlook.
* ThoseTwoGuys: With Heavy Duty. After losing a bet and having to begin training as a Ninja, he starts hanging out with Snake Eyes' apprentices and forms this dynamic with Kamakura late in season 2.

!!Long Range
[[quoteright:210:https://static.tvtropes.org/pmwiki/pub/images/longrangesigma6.jpg]]
-> '''Voiced By:''' Scottie Ray

* BadassDriver: Of his utterly CoolCar.
* BadassLongcoat: Helps accentuate his height.
* BadassBookworm: First episode in and he's reading ''Literature/OnTheRoad'' by Creator/JackKerouac.
* CanonImmigrant: Made for the series, but made it to the original toyline.
** LegacyCharacter: He's actually the second character to hold the code name Long Range.
* CoolCar: The R.O.C.C. (Roving Operations Command Center, Sigma 6's base away from home).
* DashingHispanic: Complete with GratuitousSpanish.
* FriendlySniper: His primary expertise. Nonetheless, he is one of the friendliest and most affable members on the team.
* OneHeadTaller: Though One Head Shorter than Heavy Duty, he's still the second tallest among the Joes and has a pretty big build as well (though not as big as [[TheBigGuy Heavy Duty]]).
* OutOfFocus: In comparison to some of the other Joes. Of note, he's the only Joe aside from Jinx who never really gets a focus episode or much focus ''in'' an episode other than an early outing with Spirit that showed off his sniper capabilities for the first time.
* TheQuietOne: Though he's pretty friendly to interact with, for the most part, he usually keeps to himself.
* RaceLift: The original Long Range was white, whereas this one is Hispanic.

!!Hi-Tech
[[quoteright:210:https://static.tvtropes.org/pmwiki/pub/images/hi_tech_gi_joe_s6.jpg]]
-> '''Voiced By:''' Creator/EricStuart

* DoAnythingRobot: H.O.U.N.D.
* GadgeteerGenius: Creating and maintaining the team's fancy toys is one of his primary objectives.
* HollywoodHacking: By circumstance, this is often his other primary objective.
* {{Keet}}: Relatively speaking. He's actually pretty excitable and geeky, despite being an integral member of an elite task force (similar traits can be found in Tunnel Rat and Kamakura).
* MissionControl: This is usually his function for the Sigma 6 team. Because of this and his other vital roles, his screen-time is quite generous when compared to some of the other Joes.
* [[NonActionGuy Non-Action Guy]]: Usually. In season 2, however, he has been made by circumstance to gear up and go out in the field and rescue and/or assist his fellow teammates. Still, it's telling that he is the last one to start wearing his Sigma Suit despite being its inventor.
* TheRival: To Destro, intellectually.
* ShorterMeansSmarter: Kinda {{Inverted}}, actually. He's the third tallest and also a little gangly, making him seem taller, but is nonetheless the Sigma team's resident [[TheSmartGuy smart guy]].
* TheSmartGuy: He invents the Joes' tech and also forms strategies for their missions.
* VoiceWithAnInternetConnection: In an official capacity, telecommunications is one of his job descriptions. It's why he's usually the MissionControl.

!!Jinx and Kamakura
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jinxs6.jpg]]
[[quoteright:210:https://static.tvtropes.org/pmwiki/pub/images/kamakura.jpg]]
-> '''Voiced By:''' (Jinx) Creator/LisaOrtiz, Creator/LizaJacqueline; (Kamakura) Creator/MichaelSinterniklaas, Creator/MarcThompson

* [[HighlyVisibleNinja Highly Visible Ninjas]]: Partly done as a means to differentiate themselves from Snake Eyes' black and gray bodysuits and Storm Shadow's white outfit. Their Sigma 6 outfits invoke this a little less.
* McNinja: Kamakura.
* {{Ninja}}: Jinx.
* OffscreenMomentOfAwesome: Kamakura taking down Storm Shadow on his own in the finale. The fight, unfortunately, happens almost entirely off-screen.
* OutOfFocus: Their screen-time was kind of dependent on their Sensei Snake Eyes' whereabouts. Since the reverse wasn't true, this tended to mean that the two would often be essentially swindled out of potential screen-time. In season 1, Kamakura gets injured in the FiveEpisodePilot and the two are pretty much absent for the remainder of the season up until episode 10 ''"War"''. They get a ''bit'' more screen-time during season 2, however. Kamakura more so than Jinx.
* {{Satellite Character}}s: Snake Eyes' apprentices tended to revolve around Snake Eyes, especially in the first season. They get a bit better about this in season one's ''"War"'' and the second season where they are able to spend some amount of time completing missions away from their Sensei, allowing them time to flesh out their characters, with the most noticeably positive results for Kamakura.
* SinisterScythe: Kamakura's kama.
* SwordAndGun: Just like their Master.
* ThoseTwoGuys: Jinx and Kamakura sometimes have this vibe to them, but it's played straighter with Kamakura and Tunnel Rat late in season 2.
* ToylessToylineCharacter: Jinx doesn't have her own toy.
* WhyDidItHaveToBeSnakes: As shown in ''"Giant"'', Kamakura is afraid of bugs, especially like the ones that grew giant from feeding on errant liquid plasma.

!!Spirit Iron-Knife
[[quoteright:210:https://static.tvtropes.org/pmwiki/pub/images/spirit_5.jpg]]
-> '''Voiced By:''' Darren Dunstan

* AnimalCompanion: Billy the falcon.
* BattleBolas: Spirit fights with a pair of hatchets which he can combine into a bolas like weapon.
* BraidsBeadsAndBuckskins: Averted for the most part. While he's Native American, he doesn't dress stereotypically.
* InHarmonyWithNature: A fervent believer in this. From his perspective, technology shouldn't be used more than as a tool to fight Cobra. Early on, he even went on a scouting mission without his Sigma Suit, requiring Snake Eyes to bring it to him when things began turning sour. He learns to better balance this in a late season 2 episode.
* OutOfFocus: In comparison to some of the other Joes, he doesn't appear as often.
* RememberTheNewGuy: He's just sorta of ''there'' starting from episode 6. No reason is given for why he wasn't in the FiveEpisodePilot with everyone else, either.
* ScarilyCompetentTracker: His primary role of expertise, which he is assisted in by his aforementioned falcon, Billy.
* SixthRanger: Was recruited to Sigma 6 off-screen between the FiveEpisodePilot and episode 6, contrasting most of the other members. It's the prime reason he isn't seen on things like the main page's image.
* TheStoic: Is usually portrayed as calm and in-tune with nature and his surroundings. However, when things get dire, he has shown to be NotSoStoic.
* TheStraightAndArrowPath: He favors his Bow and Arrows to other more high-tech style weapons.

!!Lt. Stone
[[quoteright:259:https://static.tvtropes.org/pmwiki/pub/images/lt_stone.jpg]]
-> '''Voiced By:''' Creator/DanGreen

* AdaptationalNationality: This Lt. Stone is English, as opposed to American like in ''WesternAnimation/GIJoeExtreme''.
* ArtificialLimbs: Has a bionic left arm after loosing the last one battling Cobra.
* CoolPlane: His Dragonhawk drop ship.
* DeepCoverAgent: His specialty. He's pretty honest about it to his allies, too. This leads Scarlett to suspect, incorrectly so, that he's season 2's mole.
* DisabledInTheAdaptation: The [[WesternAnimation/GIJoeExtreme original Lt. Stone]] had both arms, but this one lost one is battle with Cobra and replaced it with a cybernetic.
* EyepatchOfPower: Wears one to conceal a camouflage device that he can use to duplicate the attire of his enemies, specifically Cobra {{Mooks}} and Destro, for infiltration purposes, though he also supplements this with masks.
* RedHerringMole: Due to his history as a DeepCoverAgent, something that Firefly blurts out, Scarlett suspects he's the Sigma team's saboteur. She's wrong and it's Firefly himself, and she ends up getting herself and Stone captured because of it, but the latter isn't bothered by it at all.
* SixthRanger: He joins at the onset of season 2 and brings Firefly, his personal drop ship, the Dragonhawk, and a new sea base, the Sea Titan, with him.
[[/folder]]

[[folder:COBRA]]
!!Cobra Commander
[[quoteright:340:https://static.tvtropes.org/pmwiki/pub/images/cobra_commander_sigma_6_03.jpg]]

-> '''Voiced By:''' Creator/MarcThompson

* ActuallyADoombot: When defeated by Duke at the end of the FiveEpisodePilot it turned out to be a robot duplicate he left behind as Cobra Commander set the giant submarine base to self destruct after its WaveMotionGun fired.
* AdaptationalBadass: Perhaps the deadliest interpretation of Cobra Commander to date. This version is perfectly willing and able to engage in direct combat with his enemies, to the point where it seems only Duke is capable of fighting him on even terms.
* BadBoss: His EvilPlan in the FiveEpisodePilot involved firing off a WaveMotionGun from a giant submarine, and set the sub to self destruct after the cannon fired. As far the audiences knows, he did not let his subordinates in on this and planned to let them die. And when Sigma 6 manages to secure one of the Power Stones, he decides to take more drastic measures and sends out his subjects across the globe while threatening their lives should they fail to bring him even one stone. Cobra Commander even spells it out to Destro in an episode- if Destro succeeds in his mission, it's Cobra Commander's victory. If Destro fails, it's 'his' fault.
* BigBad: Of Cobra and WesternAnimation/GIJoeSigma6 as a whole.
* BroughtDownToBadass: His weapons once conventionally stopped working a fight with Duke, but he still managed to fight him on equal terms, though he ultimately lost.
* TheChessmaster: Cobra Commander organizes his own escape from prison for at least several years, for a start.
* CrazyPrepared: The entire plot of the FiveEpisodePilot is one he had set up in the event of his capture.
* DarkerAndEdgier: Not your father's Cobra Commander.
* EvilGenius: He's the one who comes up with the grandiose schemes his minions are to pull off and the Sigma team are to foil.
* EvilLaugh: Definitely indulges in these.
* EvilSoundsRaspy: He has a raspy voice.
* TheFaceless: His mask and helmet only allow his eyes to be seen.
* GeniusBruiser: A master plotter and OneManArmy who can take the entire Joes team himself and win.
* InvincibleVillain: Compared to his other versions, this one actually manages to beat Duke in combat in one of their encounters and even goes as far as to survive a WaveMotionGun and a falling rocket. [[spoiler: To top it all off, [[KarmaHoudini he even gets away scot-free in the finale]]!]]
* HyperAwareness: Duke, Spirit and Tunnel Rat manange to sneak into a Cobra base entirely undetected. Undetected to all but Cobra Commander, who was somehow able to sense that Duke and his team were there.
* KarmaHoudini: [[spoiler:The series ends with him still at large and unpunished for his crimes, though Duke is positive that the team will be ready to bring him down when he strikes again.]]
* KnightOfCerebus: Given that he's more competent than previous incarnations of the character, he tends to bring a serious tone whenever he shows up.
* LargeHam: He indulges in this, too.
* LuckilyMyShieldWillProtectMe: A BFG used by Duke at point-blank range doesn't break it.
* MaybeMagicMaybeMundane: Cobra Commander seems to possess some sort of PowerArmor that gives him the ability to project a protective shield. But then he's able to pull off feats of speed and strength that seem to be beyond the armor's capabilities.
* MeaninglessVillainVictory: Pulled off one mid way through the show when Firefly allows the rest of the Sigma Team to be captured by Cobra and forces Duke to meet and face Cobra Commander. Cobra Commander actually defeats Duke, but the rest of the team managed to escape and drove him away before he could finish Duke off.
* OneManArmy: A NonActionBigBad he is not. This Cobra Commander is more than able to hold his own in a fight, and is even able to bring his subordinates into line with the mere threat of his wrath alone. [[spoiler:He's so good, it's implied he's even able to take down Snake-Eyes.]]
* OrcusOnHisThrone: He isn't as active as his subordinates and leaves them to their own devices until he comes up with a plan himself. When he does however, he is perfectly willing to get his hands dirty.
* PowerArmor: His armor makes him stronger.
* RankScalesWithAsskicking: Believes in this and follows through perfectly.
* TheRival: To Duke.
* WeHaveReserves: His attitude with regards to Cobra's MechaMooks. As far the audience can tell he's right.
* WickedCultured: He quotes Shakespeare.
* VillainExitStageLeft: [[spoiler:He evades capture in the final episode.]]
* VillainNoLongerIdle: He'll spend most of his time in his throne room, barking out orders. But if the fight comes to him, watch out. He has no issue leaping into the fray.

!!Destro
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/destro_53.jpg]]
-> '''Voiced By:''' Creator/MarcThompson

* ArmsDealer: He's Cobra's weapons manufacturer. Most of its artillery comes from him.
* [[CoDragons Co Dragon]]: He and the Baroness are Cobra Commander's highest ranking minions.
* ExpressiveMask: Like in most continuities, Destro's head is covered by a metallic mask that somehow registers his facial expressions.
* LaserGuidedKarma: [[spoiler:Gets captured and imprisoned along with most of Cobra's higher-ups, other than the Commander and Firefly, in the finale.]]
* TheRival: To Heavy Duty in the physical sense and to Hi-Tech in the intellectual sense.
* UsefulNotes/{{Scotland}}
* SuperStrength: He is incredibly strong.

!!Baroness
[[quoteright:335:https://static.tvtropes.org/pmwiki/pub/images/baroness_sigma_six.jpg]]

-> '''Voiced By:''' Erica Schroeder, Kayzie Rogers

* AdaptationalBadass: She was plenty lethal originally, but this version engages on combat much more regularly.
* TheBaroness: Of course.
* CoDragons: With Destro, being the two most dangerous Cobra operatives after the Commander.
* DarkActionGirl: A female Cobra member who is also a capable fighter.
* LaserGuidedKarma: [[spoiler:Gets captured and imprisoned along with most of Cobra's higher-ups, other than the Commander and Firefly, in the finale.]]
* MesACrowd: She possesses special technology that allows her to project multiple holograms of herself.
* TheRival: To Scarlett.
* SpyCatsuit: She wears a form-fitting body suit.
* TheSmurfettePrinciple: She's the only female among Cobra.
* TheSquadette: The sole female Cobra operative.

!!Storm Shadow
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/storm_shadow_sigma_6_01.jpg]]

-> '''Voiced By:''' Creator/TomWayland, Creator/TedLewis

* AbsurdlySharpBlade: Just like all the other Ninja on the show.
* ArrogantKungFuGuy: He boasts to the other minions late in the series that he has never failed the Commander, unlike the rest of them (which isn't strictly true). He is also very proud of his abilities, which are, to his credit, indeed dangerous.
* BrainwashedAndCrazy: Though that was AllThereInTheManual (or in the toyline, rather.)
* TheBrute: Is often this in function, though he has the capability to be much more.
* HighlyVisibleNinja: Wearing white just anywhere will do that. He doesn't really care, though.
* HiddenHeartOfGold: Breaks off a fight with Snake Eyes to evacuate an unconscious Baroness.
* HonorBeforeReason: Yes, Snake-Eyes saved his life in "Race" and yes, we want the Joes to win, but Storm Shadow could have still paid his debt just by sparing Snakes' life instead of also giving him the power stone. The implication being that these are moments when he fights his brainwashing.
* LaserGuidedKarma: [[spoiler:Gets captured and imprisoned along with most of Cobra's higher-ups, other than the Commander and Firefly, in the finale.]]
* {{Ninja}}: He's a ninja.
* TheRival: To Snake Eyes. Probably the most ever-present of the rivalries.
** RivalTurnedEvil: [[AllThereInTheManual Because he was brainwashed]].
* ScarsAreForever: As shown in a flashback, he and Snake Eyes both have scars received in the past when they failed to properly execute a difficult technique. His is near on his chest, which is normally covered up by his clothes.
* StealthHiBye: Probably does this the most out of the Ninja.

!!Zartan
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/zartans6.jpg]]

-> '''Voiced By:''' Creator/MarcThompson

* CombatPragmatist: He prefers to attack while invisible.
* DeepCoverAgent: His specialty. It's how he was able to rescue the Cobra Commander in the series premiere. He doesn't really do this too much after that point, though.
* DirtyCoward: His holographic powers allow him to blend in and camouflage, essentially becoming invisible. When he doesn't have this advantage, however, he is quick to flee.
* EvilGloating: Especially when he's invisible.
* IShallTauntYou: Often does so by mimicking his opponents.
* {{Jerkass}}: He's a pretty condescending jerk.
* LaserGuidedKarma: [[spoiler:Gets captured and imprisoned along with most of Cobra's higher-ups, other than the Commander and Firefly, in the finale.]]
* MasterOfDisguise: Though he doesn't quite exercise his mastery as much as you'd think.

!!The Dreadknocks: Buzzer, Torch and Machete
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dreadnoks_stand.jpg]]
[[caption-width-right:350:(L to R) Buzzer, Machete, Torch]]

-> '''Voiced By:''' (Buzzer) Creator/WayneGrayson; (Torch) Creator/DavidBrimmer, Creator/TedLewis; (Machete) Creator/DavidBrimmer, Creator/EricStuart

* [[BadassBiker Badass Bikers]]: Per usual, they are a biker gang.
* BayonetYa[=/=]ShotgunsAreJustBetter: Machete
* ChainsawGood: Buzzer uses a chainsaw.
* CanonForeigner: Machete is a new Dreadnok created for this continuity.
* KillItWithFire: Torch uses a torch as his weapon.
* LaserGuidedKarma: [[spoiler:Gets captured and imprisoned along with most of Cobra's higher-ups, other than the Commander and Firefly, in the finale.]]
* SunglassesAtNight: Buzzer and Torch are always wearing sunglasses.
* SuspiciouslySimilarSubstitute: Machete for longtime Dreadknock, Ripper.
* QuirkyMinibossSquad: They are this in function.
* ToylessToylineCharacter: None of them have toys.

!!Overkill
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/overkill_sigma_6_01.jpg]]

-> '''Voiced By:''' Madeleine Blaustein

* {{Cyborg}}: He is quite boastful about this, too, referring to others as "organics" in a disdainful manner.
* EvilGenius: He creates most of Cobra's weaponry that is not made by Destro.
* InsufferableGenius: Very much so, though usually never where anyone else can hear him.
* KnightInSourArmor: Comes off as an evil version of this because of his [[TheStarscream Starscream]] tendencies that he never follows through with.
* LaserGuidedKarma: [[spoiler:Gets captured and imprisoned along with most of Cobra's higher-ups, other than the Commander and Firefly, in the finale.]]
* MadScientist: Plays this to the hilt, mostly regarding robotics.
* OutOfFocus: Since he doesn't show up in season 2 until 5 episodes until the end, conveniently with a cybernetic new body, he ends up getting the least amount of screen-time overall among the Cobra villains. Contrast Destro, who showed up often in season 2 and therefore got the most screen-time.
* PeopleJars: Stuck in one for all of season 1 and most of season 2.
* TheRival: Surprisingly forms a one-sided one with Scott, insulted that the teen was able to perfect his robotics formula where Overkill himself failed to. [[PutOnABus Scott's lack of appearance in season 2]] may partially explain Overkill's overall [[OutOfFocus lack of appearances in the same season]].
* TheStarscream: Muses about overthrowing Cobra Commander more than once, but doesn't really go through with it.

!!Firefly
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/fireflys6.jpg]]

-> '''Voiced By:''' Creator/SeanSchemmel

* TheCharmer: Enough so that he managed to fool Scarlett, in fact.
* FaceHeelTurn: Though he was never really a {{Face}} in the series proper, Lt. Stone hints that he was once a good guy around the time he first started mentoring him and [[HeelFaceTurn that he still has the potential to come around]]. Firefly's actions toward Stone at series' end give slight justifications to Stone's beliefs.
* ImportantHairCut: Shaves his head bald after being outed as TheMole.
* KarmaHoudini: [[spoiler:The series ends without him facing punishment for betraying Lt. Stone to side with Cobra.]]
* KillItWithFire: Green fire when he's with the Joes and Red when he's fully outed as a Cobra spy and saboteur.
* TheMole: Of season 2. He's the primary reason that Cobra gets such a leg-up on the Sigma team that season.
* PlayingWithFire: As mentioned, its color switched from green to red as he officially switched alliances.
* APupilOfMineUntilHeTurnedToEvil: He is this to Lt. Stone, though not enough time is spent on their backstories to find out just how their relationship was and how sincere Firefly was beforehand.
* SixthRangerTraitor: He defected to join Cobra.
* VillainExitStageLeft: [[spoiler:He lets Stone get away in their confrontation inside the collapsing North Pole Terrodrome base and in turn is the only one other than the Cobra Commander who escapes being imprisoned in the finale.]]

!Other

!!General Hawk
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/hawk_sigma_6_01.jpg]]

-> '''Voiced By:''' Tony Salerno

* FourStarBadass: He's a general.
* ReasonableAuthorityFigure: To the Sigma 6 Joes, even though he's not seen in an authoritative position much at all.
* OutOfFocus: In this case though, the argument could be made that he wasn't really intended to be focused on much. Due to the events of ''"Valor Vs. Venom"'', he is recuperating in the hospital during the series proper. His biggest contribution is that of his son, Scott.
* PutOnABus: Though he's mentioned, he doesn't show up at all in season 2.
* ToylessToylineCharacter: He has no toy.

!!Scott Abernathy
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/scott_2.jpg]]

-> '''Voiced By:''' Creator/MatthewLabyorteaux

* GadgeteerGenius: He's quite the prodigal roboticist, managing to perfect Overkill's venom formula to power his creation, a robot dog named Spud.
* HollywoodHacking: It's how he acquired Overkill's formula and alerted himself to Overkill's presence in the first place. Later, after being captured and brought to Cobra's Submersible Base and freed by Snake Eyes, he helps the Sigma team out by hacking in and causing the base to surface prematurely, allowing the rest of the team sans Duke to board. Hi-Tech even complements him on his skills.
* KidAppealCharacter
* KidSidekick: Is eventually made an honorary member of Sigma 6.
* ThePasswordIsAlwaysSwordfish: Apparently, General Hawk keeps his files locked behind a very simple, five-lettered password. ''"Scott"'' actually begins to see his father in a new light when he clues out said password.
* PutOnABus: Like his father, he and Spud don't show up at all in season 2, bar a brief voiceless cameo in ''"Ice"'', though at least his dad gets mentioned even if he never appeared at all.
* TheRival: Though it's completely [[UnknownRival one-sided on Overkill's part]].
* TagalongKid: To Sigma 6. He's a teenager who occasionally helps them on missions.
* ToylessToylineCharacter: He has no toy.
* WhenYouComingHomeDad: Scott starts off resenting his dad for often being away or indisposed because of his job. After finding out from Overkill why his dad was in the hospital and helping Sigma 6 out with destroying the "Thor's Hammer" super weapon, Scott gains a new-found appreciation and respect for his dad's work.

!!Spud
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/spud_4.jpg]]

-> '''Voiced By:''' Tony Salerno

* BigDamnHeroes: Manages to save the day, and Scott, more than once.
* InstantAIJustAddWater: Well, a watery like solution ''did'' enhance Spud's A.I. after all.
* IntellectualAnimal: Due primarily to Overkill's formula that Scott perfected (mostly unintentionally) in creating him.
* MechanicalEvolution: Happens when Overkill sends robots to attack, then later capture, him and Scott. Scott realizes that each time they're attacked or in a tough spot, Spud's A.I. evolves and adapts to come up with ways out of it.
* RobotDog: He's a robotic dog.
* SuperStrength: Noted by Overkill as being almost as strong as his Overlord Vector, though Spud's not invincible by any means.
* TeamPet: Is this as an honorary Sigma 6 member.
* ToylessToylineCharacter: Despite that fact that he would seemingly make a great toy, being a multi-purpose RobotDog and all.
* UrineTrouble: In the FiveEpisodePilot, he disables Cobra's giant laser cannon by "peeing" hydraulic fluid on its power core.
