- Complete Monster (dub only): Megatron is the leader of the Predacons, who arrived on Earth in search of the Autobot Weapon Fortress Maximus under the pretext of raiding Earth for its energy. Upon arrival, he kidnaps Doctor Kenneth Onishi and probes his mind to find the location of Fortress Maximus. After receiving knowledge of the Autobot Protoforms, Megatron corrupts their sparks in order to create his Decepticons. Although initially A Father to His Men to his minions if they prove themselves worthy of respect, he discards these qualities upon his rebirth as the Decepticon Galvatron—absorbing the energies of the Predacon Brothers against their will to power his new body immediately upon his transformation, and later reducing Scourge and the Decepticons to mindless drones for plotting to overthrow him with the use of Fortress Maximus. Galvatron's worst actions, however, came during the finale when, after surviving a battle with Fortress Maximus, he transforms into bat form and drains Fortress Maximus's energy to power himself. He then unleashes his bat swarm to brainwash human children with the goal of enslaving them and repeating the process from planet to planet until he has conquered the universe, threatening to harm the children if Omega Supreme or the Autobots intervene. When the Autobots flee into the Space Bridge, Galvatron sends the Decepticons to pursue with the intention of destroying both groups by collapsing the Space Bridge, not caring if any Predacon gets caught in the collapse, all so he could have the entire planet to himself.
- Crazy Awesome: Despite being the main villain, you gotta admit that Megatron/Galvatron having seemingly 40 different modes, including a giant freaking hand is pretty friggin' cool; they even put it in on the toy!
- Ear Worm: Despite being only 30 seconds long, this series' rendition of the classic Transformers theme is damn catchy.
- Ensemble Darkhorse: Mirage. Being a cool F1 car that is a lone sniper helps a lot.
- Scourge, owing almost entirely to his design and toy being one of the best in the series, and for being, oddly, one of the only Black Convoys/Nemesis Primes to have an actual character outside of being an evil clone.
- Sky-Byte is generally seen as the best character overall, and the only one to have received a non-repaint new toy in the years since. Fansite TF Archive, which mostly disliked the series, called him "a Beast Wars character who wandered into the wrong show."
- Franchise Original Sin: Robots In Disguise had some issues such as choppy animation, episodes that didn't contribute much to the overall story, too much focusing on selling toys, some annoying human characters, and spotty dubbing and voice-acting. Despite this, it managed to be fairly good and did a lot of things right. Its follow-up, The Unicron Trilogy (particularly Armada and Energon), took everything negative about RID and amplified them by ten while losing track of everything it did right.
- Germans Love David Hasselhoff: Robots in Disguise is more popular in the USA than Car Robots is in Japan, probably due to the Woolseyisms, Mythology Gags, and the heavy fan backlash against the Unicron Trilogy.
- Hilarious in Hindsight:
- So Okay, It's Average: General consensus is that it isn't the best Transformers series, but it's definitely not the worst.
