Jekyll and Hyde: Noble is benign to a fault and Savage is practically uncontrollable. Initially this turns out to be an act since Noble is actually Megatron stuck in his organic half. After they split, however, the trope is played somewhat straight - though neither Noble nor Savage display any sentience.
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.
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."
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.
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.
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 apparently happy Megatron freed him from his 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 admit to Blackarachnia about what really bothered him is he's done terrible thing as Jetstorm and doesn't know if things can go back to the way they were. But Blackarachnia was willing to try.
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.
The Starscream: Once he regains his intellect, anyway. He would have succeeded if Megatron hadn't been Genre Savvy enough hardwired his programing to ensure that he could never kill him.

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.
Brains and Brawn: Both are brilliant tacticians, but Strika is easily the more combat oriented of the two. Obsidian's more of a strategist, coordinating drone attacks.
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?
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 generals in the history of Cybertron.
