- The Big Guy
- Emo Teen
- Jerk with a Heart of Gold
- Make Me Wanna Shout: His power.
- Our Vampires Are Different: Nightscream can shoot his fangs at an enemy and drain the energy from them via a connecting cable.
- Sole Survivor: As far as the Maximals know, anyway. Nightscream is the only one they find, but then they never really leave Cybertropolis.
- Survivor's Guilt
- Tagalong Kid
- A Boy and His X: After Megatron's spark exits him and he loses sentience, he has this relationship with Nightscream.
- Instant Awesome, Just Add Dragons
- Jekyll & Hyde: Noble is benign to a fault and Savage is uncontrollable. Initially this turns out to be an act since Noble is actually Megatron stuck in his organic half. After they split, the trope is played somewhat straight - though neither Noble nor Savage display any sentience.
- Killed Off for Real
- Mix And Match Creature: of a dragon and a wolf.
- Noble Wolf: Fittingly enough, the wolf aspect calls itself "noble" and is a pretty Nice Guy.
- Redemption Demotion: A very strange case. After Megatron's spark takes over the Grand Mal his Noble/Savage body continues to live on with only a primitive animal intelligence.
- Team Pet
Voiced By: Kathleen Barr
- Action Girl: Although she dislikes violence.
- Affirmative Action Girl
- Belligerent Sexual Tension: With Rattrap.
- Green Thumb
- Plant Alien
- Shock and Awe: A rarely-used chain lightning attack that vaporised a swarm of tank drones in her debut.
- Shout-Out: The planet where she got her "beast mode" comes from Mainframe Entertainment's other toyline based cartoon.
- The Smart Girl
- Toyless Toyline Character
- And I Must Scream: Subverted. Waspinator was fully aware of what was going on, but didn't care because he enjoyed it so much. It's also slightly implied that he had greater control than Jetstorm and Tankor, citing his "the brooding loner bit."
- Badass Biker: Well, bike, anyway.
- Badass Baritone
- Butt Monkey: For a while mid second season, it seemed as if Thrust resumed Waspinator's old role, being bashed by everyone. Given that he is Waspinator, this was likely intentional. By the end of the series, he has regained the respect of his fellow Vehicons and is no longer bashed around.
- Sparkjacked And Crazy
- Card-Carrying Villain
- The Dragon: For part of season 2.
- Enigmatic Minion
- Honor Before Reason: He doesn't care about what Megatron will do to Cybertron.
- The Slow Path
- That Man Is Dead: Actually, he's the only one of the original three not to bother with this trope at all.
- Took a Level in Badass
- Undying Loyalty: He was Megatron's faithful servant until the very end even when the latter was seemingly killed. He has nothing but hatred for any perceived traitors, especially Jetstorm/Silverbolt.
- And I Must Scream: As Silverbolt, he indicates that he was aware of what Jetstorm was doing as well.
- The Atoner
- Ax-Crazy: Even by Transformers villain standards, Jetstorm is completely out of his mind.
- Battle Couple: With Blackarachnia.
- Card-Carrying Villain
- Everything's Better with Samurai: After his reformat, his robot mode is designed to look like a samurai.
- Evil Has a Bad Sense of Humor: Which doesn't stop him from being absolutely hysterical at times.
- Evil Laugh: "Whoa-AH hahahahahaha!!!"
- Faux Affably Evil
- Good Was Dumb: After being reformatted, he told Blackarachnia he doesn't like the person he used to be because he "believed in things", and was glad Megatron freed him from his code of honor. But after Megatron tries to convert him again by promising he can have everything he wants, Silverbolt shouted "You've given me nothing!". He later confessed to Blackarachnia about what really bothered him: he's done terrible thing as Jetstorm and enjoyed it, and doesn't know if things can go back to the way they were. But Blackarachnia was willing to try.
- Heel–Face Turn
- Knight in Shining Armor: Subverted.
- Knight in Sour Armor: After his reformat.
- Laughably Evil: Jetstorm is without a doubt, insane. But he's also loads of fun to watch.
- Sixth Ranger
- Sparkjacked And Crazy
- That Man Is Dead: Jetstorm is actually just a shell program created by Megatron, so he "dies" when Blackarachnia reformats him into Silverbolt.
- Conversely, after finding out the truth, Jetstorm was emphatic that "Silverbolt had left the building!"
- In the finale, it appears Silverbolt is back to his pre-Jetstorm self.
- And I Must Scream: Rhinox says that he was trapped inside Tankor, fully aware of what was going on, but unable to reach the surface and communicate.Rhinox: Trapped! Abandoned!
- Death Equals Redemption
- Dumb Muscle: Subverted. Tankor is inarguably dumb and powerful, but exactly how aware or in control Rhinox is of Tankor's actions is never really clarified.
- Hulk Speak
- Manipulative Bastard: To the point of forcing Megatron himself to do whatever he wants, without his knowledge... until Megatron turned all the gambits to his favour.
- Obfuscating Stupidity: Upon regaining his true personality.
- Sparkjacked And Crazy: Inverted, he was always on the evil side.
- The Starscream: Once he regains his intellect, anyway. He would have succeeded if Megatron hadn't been smart enough to hardwire his programing to ensure that he could never kill him.
- Tank Goodness: It's in the name.
- That Man Is Dead
- Third-Person Person
Obsidian & Strika
Voiced By: Paul Dobson (Obsidian), Patricia Drake (Strika)
- Affirmative Action Girl: Strika was made a female to address the gender imbalance. The writers also introduced Botanica, a prominent character with no toy, for the same reason.
- Awesome Personnel Carrier: Strika. She's even named after a real life example, the Stryker.
- Badass Bookworm: Obsidian.
- Battle Couple
- Brains and Brawn: Both are brilliant tacticians, but Strika is easily the more combat oriented of the two. Obsidian's more of a strategist, co-ordinating drone attacks.

- Future Copter: Obsidian's basically a futuristic version of the V-22 Osprey.
- Genius Bruiser: Strika.
- Hero Killer: Both of them.
- Hulk Speak: In their Establishing Character Moment, they use this to trick the Maximals.
- My Planet, Right Or Wrong: They are both extremely loyal to Cybertron - even if the guy running it happens to be an organophobic lunatic with a God complex."Megatron is Cybertron. To defend one is to defend the other."
- Thrust calls them on it.Thrust: If you're loyal to everyone, can you really be loyal to anyone?
- Thrust calls them on it.
- Obfuscating Stupidity: How they lure Primal's team into a trap during their first appearance.

- The Strategist: They were two of the most brilliant Maximal/Autobot generals in the history of Cybertron.
- Tiny Guy, Huge Girl

Voice By: Christopher Gaze, and Paul DobsonA small, spherical drone that acted as, more or less, Megatron's butler.
- Brainwashed: Is reprogrammed by Tankor to serve him in his vendetta against Megatron.
- Cyber Cyclops: His eye is actually the middle one, not the two lights on the side of the "face".
- Demonic Possession: Killed by the energy storm started by Tankor, his body comes to house Megatron's wayward spark.Megatron: I live! I live! I—...what kind of puny body is this?!
- Flight: Floats around.
- Evil Brit: Despite being Cybertronian.
- Non-Action Guy/The Unfought: As he has no offensive capabilities, and could probably be taken down in one shot.
- The Soulless: Despite his intelligence and personality, it's explicitly stated that he has no spark.
