- Complete Monster: Dr. X is the mastermind behind all the evil in the series, committing all his crimes in the name of evolving humanity into perfection for him to control. Before initiating his more monstrous actions, X, requiring a new body for himself, kidnaps a young man named Brendan Caine, subjects him to torturous experiments that turn him into a Super Soldier, then transplants his own mind into Caine's body. X then becomes free to spread his influence worldwide, and immediately forms his Council of Doom, after which he begins various attempts to "test" humanity to determine which of them is most suitable to become part of his "Neo Humanity". These so-called tests range from trying to start a nuclear holocaust and flash freezing the entire planet, to infecting millions with a virus he hopes will lead to them ripping each other apart, leaving only the survivors for him to horrifically transform into his personal super soldiers. Showing numerous times that any well-intentioned claims are utter hypocrisy, not only does X regularly attempt to kill hundreds of innocents out of nothing but spite toward his Arch-Enemy, Action Man, but X's plans to "improve" humanity always amount to simply replicating his own mind onto everyone else. In the finale of the series, X finally loses whatever sense of reason he had when he decides to drag an asteroid to crash into the Earth and wipe out everything, including his own Council of Doom, then just rebuild humanity from scratch with himself as the base reference. A complete and total psychopath unable to comprehend the fact that imperfections are what makes humanity special, Dr. X was so convinced of his own godlike infallibility that he failed to realize just how maniacal and petty his goals were.
- Ear Worm: The opening and ending theme(s) for the show. Thank you, Paul Gordon.
- Genius Bonus: The AMP Factor is loosely based on the concept of Laplace's Demon, albeit in miniature. Another nod to an old-timey science theory occurs in the aforementioned peace summit episode, where one of the warring nations is known as Phlogistan, a play on phlogiston, an antiquated theory of heat exchange best known today for its appearance in Tom Strong.
- Narm: Dr. X calling Alex Mann by his actual name while he's a dude in distress would be more impressive if he did not call him "Mr. Mann".
- Uncanny Valley: The early 2000s Action Man was one of the earliest All CGI Cartoons, and it shows. The characters look incredibly off and robotic by today's standards.
