Doctor Komodo is one of the longest active super villains of the world, although his activities have included interrupted periods of many years. He first appeared during the Second World War near Komodo Island and was responsible for slaughtering a large contingent of Japanese soldiers. History has suggested that Komodo slew the Japanese with the assistance of mutated komodo dragons, although his dabbling into nuclear power and radiation came later which suggests the dragons were most likely not irradiated at that time. Komodo himself has never explained the true nature of his success against the soldiers and has even dismissed the incident as a false memory at times. Considering the many and varied experiments he has subsequently subjected himself to it is quite possible that Komodo is no longer in full command of his sanity which may have impacted on his memory. On the other hand it may simply suit him to have the stories of his early years distorted or disputed.

After the Second World War Komodo was famous for attacks in South East Asia and was a principal member in many countries' call for independence: most notably the formation of Indonesia. While he had some contacts within the military of the emerging Indonesia, he seemed more interested in pushing out the Europeans than with establishing any kind of government. During the 1950s and 1960s he appeared quite mad and erratic, often threatening Australia and New Zealand as well as Hong Kong and other areas frequented by Europeans. His threats were usually thwarted although the damage was generally astronomical. He constructed giant robots, mutated komodo dragons and even managed to trigger a series of tsunamis.

In the 1970s Komodo made his way (inevitably) to Sauropolis where he was grudgingly accepted by the dinosaur society. Although he only spent a few months in the hidden land he managed to become privy to unusual science and when he reappeared in the world he had mutated himself into a saurian-human hybrid. During this time he battled heroes across the Pacific, even to San Francisco. His evil genius was still there but he seemed to rely more on brute strength and a cunning predator's instincts. Because of this he ended up nearly beaten to death many times and was also the man responsible for numerous bloody deaths and injuries to others.

In the 1980s, Komodo changed again, reverting to human form and nearly-responsible and law abiding persona. He established himself as Dr Sukarno and helped form the pseudo-super hero team known as the PACERS (PACific EnforceRS). His genius provided the young team with fantastic gadgets and a brilliant tactical mind, but it all proved to be a ploy and Komodo sent the PACERS to their deaths against the criminal power broker Evol Khan who was, at the time making moves in Asia. The demise of the PACERS made fleeting international news but when it was over Komodo discarded any dreams of being a 'good guy' and returned to his original interest in the komodo dragons.

He began breeding mutant komodo dragons and trained them as efficient and hardy killers. Still human in appearance he generally carried out crimes from behind the scenes, sending out the dragons to rob banks and silence threats. These clandestine activities somehow led Komodo to meet with the Infinite Man and the two hatched a plan to take over the world - beginning with the subjugation of the Sentinels. Komodo used his growing army of mutant komodo dragons to draw the Sentinels into three areas: Singapore, Taipei and Jakarta. With the team split, the Infinite Man was able to transform the heroes into statues. Unfortunately for Komodo, the Singapore Samurai were able to intervene in the Infinite Man's plans in Singapore, and Atomic Girl proved to be able to withstand the Infinite Man's powers. She channelled his powers through her body and then into the body of Komodo, who mutated again into a lizard-like creature. The transformation drove him insane, at least for several years, and during that time he lost his entire fortune.

However, as in most of his stories, Komodo returned bigger and more determined than ever. In the current world, Doctor Komodo is a mad scientist with the body of a powerful uberhuman. He combines his wit and strength to maintain his wealth and advance his creations. He seems destined to come up with glorious plans to destroy or enslave the world, but even his most grandiose plans always come unstuck. It is his curse.

Komodo is generally considered a mad scientist with an obsession to take over the world. During most of his career he has utilised various inventions or harnessed mutated komodo dragons to achieve this goal, although he has never succeeded. He is certainly egotistical and rarely considers the views of others. A rare exception to this has been Princess Komodo, his genetically engineered 'daughter', although his fatherly protection of her waxes and wanes even more regularly than the moon.

At times he has shown some variation on the desire for world domination, particularly evident in his days as a pseudo-hero leading the PACERS, although his true motivations during this time are clouded in mystery. It may have been an attempt to reinvent himself, a case of concussion or a masterful plot to destabilise the Asia-Pacific region.

What remains true to this day is the Doctor Komodo is a major threat and is likely to unleash devastation on a large scale to achieve his plans to take over the world.

"BWAHAHAHA, I am Doctor Komodo, you blithering fools. Pure intellect housed in the indomitable form of nature's grandest killing machine!"

Throughout his career Komodo has generally been considered a gadgeteer, able to construct masterful and deadly devices to use against his opponents. His genius level intellect has given him the edge over many heroes and law enforcement agencies. When he first took on the appearance of a humanoid lizard he seemed to lose this intellect and devolved into a classic thuggish villain, smashing opponents with little regard to strategy.

in his current form, Komodo has his intellect and his devices as well as the power of a lizardlike man. He is strong, incredible fast and able to withstand your regular superhero attacks at least for the short term. He lacks natural impervious defences but has been known to create force field generators, and given the time he can generally come up with a defence for anything or any one.

His latest mutated form can breathe underwater and exist in most dangerous environments as well as being immune to most animal toxins. His thick tail is his primary weapon and is capable of slamming even the most buff of heroes. Once he unleashes his claws and teeth on a prone body he is known to rip out throats and cause horrible gashes. There are rumours that his bites can cause disease, but this has not been proven and could have been a serum he created rather than a natural ability.

Perhaps his most dangerous ability is to unleash hordes of irradiated, mutant komodo dragons. The lizards have been bred by the doctor for decades and he always seems to have more of them locked away in deserted Pacific islands ready for a fresh onslaught. At one time he managed to call upon over one hundred and fifty of the beasts to over-run an American naval base in the Philippines.

Doctor Komodo is a very large humanoid lizard. He has dark eyes and a harsh snout which is lined with razor-sharp teeth. His skin is grey and hard with calluses gouged along its surface from previous battles which have never fully healed despite his famous regeneration ability. He has a thick tail which measures nearly 150cm, and although it is not prehensile or useful for manipulation it does assist him with balance and delivers a powerful blow to enemies.

His clothing changes depending on his needs, but he is most commonly associated with a classic white lab coat.

Before his transformation into a komodo dragon hybrid Komodo was obviously of Indonesian descent, probably Javanese. The last photographs of him show him to be a slightly overweight man in his fifties with round glasses and a rather severe hair cut. Since his transformation most experts assume he will never look that way again.
