Doctor Chaotica

Doctor Chaotica was a holodeck character from The Adventures of Captain Proton. As the self-styled "ruler of the cosmos", Chaotica was the sworn enemy of the planet Earth, and was constantly trying to conquer the world, with the aid of an army of minions, led by his faithful – if unintelligent – henchman Lonzak. Chaotica's nemesis was none other than Captain Proton, the "scourge of intergalactic evil." ()
In 2375, the program was running when was stuck in subspace, where photonic lifeforms who lived there mistook the program as being a true representation of the universe Voyager resided in. The aliens visited Dr. Chaotica's lair believing that they were meeting a real person. Dr. Chaotica told them that he would crush them like insects and promptly executed one of the aliens. The other transported away. This triggered a war between the aliens and Chaotica. The program could not be shut down due to damage to Voyager, so in order to end the war with the aliens, the crew assumed various roles in the program. As usual, Tom Paris became Captain Proton himself, with Harry Kim as his sidekick, Buster Kincaid. The Doctor took on the persona of the President of Earth, in order to communicate with the photonic aliens, who dismissed the carbon-based Voyager crew members as "illusions". 
 Most importantly, Captain Kathryn Janeway assumed the role of Queen Arachnia, in whom Dr. Chaotica had a romantic interest. Dr. Chaotica made Arachnia promise to marry him if he would drop his shields. He later imprisoned her and told her that he would not kill her until after the wedding night. Janeway and the rest of the crew were able to defeat Chaotica, stopping the war with the aliens and releasing Voyager from subspace. As Dr. Chaotica was dying, he told Arachnia that he would return.

In 2377, when Voyager was separated into several different timeframes, one of the frames on the holodeck played host to Captain Proton again. When Chakotay and a past Captain Janeway were attempting to save the ship, they were caught on the malfunctioning holoprogram. Chaotica believed Janeway was Arachnia and vowed to kill her. However, the two "convince" him of a "greater threat", aliens from the Eighth Dimension (Chaotica and Lonzak laughed at first, because "everyone" knew there were only five dimensions) and they showed a piece of Voyagers gel-packs as "proof".

In 2381, as Voyager was being transported to Earth by the crew of the , a Tak Takian macrovirus was discovered and escaped through the ship thanks to Brad Boimler's bungling. As it reproduced and made its way through the ship, it activated three holodeck programs -- Chaotica, The Clown and Michael Sullivan -- who proceeded to take control of the ship and make its way towards a Borg cube. Boimler and Sam Rutherford made an attempt to take control of the ship with the former as a distraction. When cornered by Chaotica, Boimler declared that he wasn't a Starfleet officer, but the son of Captain Proton, causing Chaotica to gasp in shock before Rutherford shut down the holograms and the rest of the ship by infecting it with Neelix cheese.
