Dr. X or Doctor X is a mad scientist who serves as the arch-enemy of Action Man in its line of toys, introduced in 1993. Despite his many changes in appearance, he's easily identified by his mustache, almost-to-totally bald head, bionic arm, and prosthetic eye (sometimes replaced by an eyepatch). For those wondering, he received his PhD in theoretical physics from University College London in the United Kingdom, having completed his undergraduate and one placement year working as an assistant mad scientist for the NHS.
Dr. X is a danger to the world and one of the most intelligent criminal masterminds ever known. He leaves a trail of death and destruction wherever he goes.
In the toy-version plot, Dr. X is bent on ruling the entire world and prepared to kill anyone who stands in his way. He has recruited many villains into his army over the past years such as Plague Locust (from PC game), MAXX (or '"The man with no name") (1999), Tempest (2001), Asazi (Mainframe animated series), Anti-Freeze (2003), No Face (2004), and Professor Gangrene (1997, 2000, 2002, 2003).
During his battles with Action Man, Dr. X has constantly been defeated and humiliated. However, this evil scientist never seems to give up and each time Dr. X returns to do battle, he grows stronger. Action Man may believe him to be defeated, but Dr. X can strike fear and destruction across the world at any time, forcing entire nations down on their knees. Who knows, he may already be secretly ruling over certain parts of the world.
While Dr. X threathens the world, there seem to have hinted of a connection with the amnesiac Action Man.
According to the series bible, Dr. X's real name is Dorian Exler. During his childhood, Exler's parents adopted a younger child named Matthew (who would later becom Action Man). Under the tutelage of their father, Dr. Exler, both sons were geniuses from an early age and became science prodigies. However, Dorian was a bad seed; a born psychopath who ultimately was responsible for deliberately setting the fire which killed his parents. And, in the aftermath of his heinous act of patricide, Dorian cleverly made young Matthew think that he was responsible for this "accident".
Each son received an inheritance of a handsome trust fund. So Dorian, using his inherited wealth as seed money while nurturing it with his raw genius-level intelligence, ruthlessness, and powerlust, not only grew his financial fortune by a multiple of thousands, but built up a vast private para-military/terrorist organization named The Council of Doom, staffed by mercenary soldiers called "Skullmen".
Using a combination of high-level computer hacking and corrupt government officials on his payroll, he destroyed all records of his own past before assuming the mysterious phantom identity of Dr. X.
Meanwhile, Matthew was finally able to recall the circumstances surrounding his parents' death in vivid detail -- and realize that it wasn't an accident caused by him, but murder at the hands of his brother.
He returned to the western world with extraordinary mental and physical skills, along with an obsessive personal mission. Matthew knew he must bring to justice the killer of his parents (and avenge his own years of suffering the guilt of thinking he had killed them). Also, at the same time, he must protect the world from his deranged brother. For the sheer force of evil Dr. X was known no better to anyone than his younger brother Matthew -- now fully aware of the psychopathic depths to which his brother was capable of sinking in his lust for power and control.
Lacking anything remotely approaching the resources and paramilitary organization of Dr. X, Matthew decided to destroy his brother from within by infiltrating his organization. After some time working undercover as a Skullman, Action Man was ready to take down Dr. X.
Shortly after this, Matthew is assigned to a mission with Dr. X and his Skullmen. However, while on the mission, they cross paths with the Action Force. During that fateful night, at a chalet in Switzerland, Matthew blew his cover (and everything that he had worked for) to save the innocent lives of Action Force. The result was an explosive concussion, combined with traces of Dr. X's psychotropic drugs, which caused him to lose his memory -- including his vast knowledge of Dr. X's empire, Dr. X's own personal past, and Matthew's shocking relationship to Dr. X.
Meanwhile, Dr. X learned the true identity of the infiltrator who knew so dangerously much about his organization, and came so close to taking Dr. X's entire empire down. He also learned that this infiltrator (his brother) now had amnesia. This means that all of the dangerous information about Dr. X's involvement is locked away (for the moment irretrievably) in Action Man's concussed brain.
In order to try to ensure that Matthew's memory doesn't return, Dr. X has used his extensive technological resources and worldwide network of corrupt officials to erase any trace of his brother's personal history or identity. Just as the man known as Dorian Exler disappeared from all private and public written records, it's now as if Matthew Exler never existed either...
Dr. X's appearance in this series appears to be a shirtless version of the 1996 figure. He's depicted speaking with a heavy South African accent. Rolf Leenders provides the voice for Dr. X.
In this series, Dr. X started off as an old handicapped, brilliant geneticist and bio-engineer who's goal is to build a genetically-enhanced race: Neo-Humanity. The plan was disbanded after WWII with the Soviet Union. However, Dr. X continued that work in private as his old associate, Simon Gray, made it his mission to stop these plans. That is until X learns about Grey giving the power of the AMP Factor to his student, Alex Mann the Action Man.
Dr. X captured and tested Alex Mann repeatedly, as well as his best friend Brandon Caine. Dr. X injected nanotech enhancements in Brandon's blood stream, making him superior to Alex in battle and athletics. The culmination of these experiments was for Dr. X to transfer his mind into Brandon's body, becoming young again and a nanotech cyborg. Thanks to the AI program, he planned to infect many others with it, but failed in the end.
Dr. X later founded the Council of Doom with his evil cohorts: Asazi, Tempest, and later Gangrene & Quake. A breed of nanotech trilobites rebel against X as they appear to gain collective intelligence and rebel against him; but this was actually Brandon Caine's uploaded mind punishing Dr. X for taking his body.

Direct to video movies
In Action Man: Robot Atak, No Face re-builds Dr. X, who was badly damaged after a battle with Action Man, which could have happened many years earlier. He plans to use a mind-controlling gas on Earth's population, but Action Man and Action Force stop him before causing his headquarters to explode.
In Action Man: X Missions, Dr X kidnaps various people and transforms them into his Toxic troopers, but Action Force manages to turn them back to normal, before incarcerating Dr X.
In the movie, his Komodo Dragon is named Snap. This version of Dr. X is over the top and emphasises words with the letter X in them.
In both of these movies he is voiced by Steven Burkoff.

Dr. X over the years has seen new styles. In 1994 - a rotary, firing shield; In 1995 - a laser eye & exposed brain; In 1996 he had a bio-stomach (toxic guts); the 90s series used this look; in 1997 - a firing hand; in 1998 - a chopper bike; in 1999 - a laughter button; in 2000 - a robotic arm; in 2001 - a bronze arm and ball & chain; in 2002 - a firing missile arm; in 2003 - a chest cavity housing a missile launcher. Two more versions were released: one came with Action Man in a pack named "Ultimate Battle". The final version of 2003 came with another Action Man; this version of Dr X was meaner looking and was mostly covered in amour. When the "x" was hit on his chest he would scream. He also came with a chainsaw and claw arm. When these were plugged into him, he would laugh. In the comics, readers could vote whether Dr. X would live or fall to his death hence the reason this set was called Final Combat. Dr. X did plummet to his death, but evil never truly dies - it is merly reborn. In 2004 he was brought back, rebuilt by No Face. This version of X looks similar to the Final Combat version. When the "x" on his chest was pushed, he would fall apart similar to the X Robots. This version of Dr. X is featured in Action Man: Robot Atak.
In 2005, he came with a komodo dragon named Dragon X. This version of Dr. X appears in the X Missions movie.
