Vigo was born in 1505 in the small Balkan kingdom of Carpathia in Hungary. He soon rose to power and ruled his home country with an iron fist, and the land itself was in a constant state of spiritual turmoil thanks to his despotic rule, which earned him an infamous name, the "Scourge of Carpathia." Vigo later conquered another land, the country of Moldavia in Romania which its people while still resenting the psychotic autocrat, gave him another notorious alias, the "Sorrow of Moldavia." It was said he was a powerful magician and a genius in many ways, as well as a tyrant, an autocrat, a lunatic and a genocidal madman. Because of his evil ways he wasn't well liked by his subjects and he killed hundreds of them. He was also known as "Vigo the Cruel," "Vigo the Torturer," "Vigo the Despised," and "Vigo the Unholy." Peter Venkman jokingly adds "Vigo the Butch" to the list of aliases.
He eventually died at the age of 105 in 1610, but not because of his old age. His people had led a rebellion and they tried and executed him in a manner that they saw fit for his rule. He was poisoned, shot, stabbed, hung, stretched, disemboweled, drawn and quartered (to which Venkman commented "Ouch"). Just before his head died, he uttered this prophetic warning: "Death is but a door. Time is but a window. I'll be back!"
True to his word, he returned in modern day New York in 1989 and took up residence in his self-portrait that was created long before the events of his death. Vigo used the river of Psychomagnotheric Slime (also known as Mood Slime), generated by a Sloar, which flowed through abandoned subway tunnels to a location underneath the city's Manhattan Museum of Art, where Vigo resided. The Mood Slime boosted Vigo's powers, and enabled him to channel people's negative emotions needed for the manifestation of an army of angry spirits that soon started terrorizing New York City. Although the slime granted Vigo power enough to manifest, he could not regain a physical form. For this reason, Vigo needed a baby to possess.
Vigo manipulated the museum's curator Janosz Poha into bringing Dana Barrett's baby Oscar to the museum of art, so that on the eve of the new year he could possess her child and be reborn and freely rule the world once again. Vigo's plans were halted by the Ghostbusters. They attacked him with positively charged slime and blasted him back into the painting, completely draining all his powers. After that, the painting of Vigo became an image depicting the Ghostbusters as heavenly saints.
Vigo resides in the Firehouse in his painting near Janine's desk on the right from the Firehouse doors. If the Rookie interacts with the painting, it will talk to him, with over 100 different line variations. Its reason for existence is unknown, seeing as it was melted at the end of the movie to reveal a painting of the Ghostbusters.
An explanation could be that this is not the original painting, but a replica that Vigo's spirit now inhabits. Another possibility is that the painting of the Ghostbusters (which itself was created by changing Vigo's powers into positive energy) still held what's left of Vigo after his defeat, and after some time it returned to its normal form (Vigo painting). However, Vigo's spirit is still rather powerless and unable to act outside the painting, making it unessential to even put him into the Containment Unit. Another theory is that the Psi Energy Pulse generated by Ilyssa Selwyn could have reverted the painting back to its original form.
Years after the Thanksgiving 1991 incident, the Vigo painting is still in the garage bay of the Firehouse. Idulnas briefly took on the guise of Vigo to taunt Janosz into serving him.
A couple weeks into the Tiamat incident, Vigo suddenly vanished from his painting. He resurfaced on Hart Island and raised the dead buried at the potter's field to serve as his army. The resulting P.K.E. surge attracted the Ghostbusters' attention. Special Agent Melanie Ortiz shot Vigo in the face with her Proton Pistol. Angered someone dared to strike him, Vigo fixated on Peter, whom he referred to as "The Vandal," instead and shot at him. The Ghostbusters, Chicago Ghostbusters and Ghost Smashers converged on the potter's field upon Peter's insistence. They opened fire on Vigo, who called to the Hart Island Ghosts. In a surprise turn, the ghosts pried the Proton Streams from Vigo.
Vigo grabbed ahold of Ron Alexander and gloated about his impending death. With Ray still in a trance state, Ron took matters into his own hands and activated his Boson Caster. Vigo was shot point blank in the face. As Vigo's head reformed, Winston grabbed Ray's Slime Blower and opened fire. Vigo taunted Winston and declared the Hart Island Ghosts would prevent the slime from touching him. Winston was counting on this. Slimed with positively charged Psychomagnotheric Slime, the ghosts were free from Vigo's control. They immediately swarmed Vigo like hungry piranha. Vigo's form was slowly dispersed, evidenced by his left hand being reduced to a skeleton. When the Ghostbusters returned to the Firehouse, Vigo was back in his painting but with scorch marks on his head where he was blasted by Melanie Ortiz. Peter promised to help cover them up with a pastel colored beret.
Though this tome is almost exclusively intended as a reference for spirits, I think it's worth noting briefly the life of one Prince Vigo Von Homburg Deutschendorf. Taking notes from my colleague Leon Zundinger's work Magicians, Martyrs And Madmen, I've learned that Vigo lived between 1505 and 1610. His unnaturally long life didn't end easily, as the villagers in his kingdom tries several methods of getting rid of him before something finally worked. His last words were: "Death is but a door, time is but a window. I'll be back!" I suspect he had means already secured to insure this will eventually happen.
Vigo is a Class 4 entity. When the river of slime beneath the streets of New York became negatively charged, the spirit of Vigo grew quite powerful. With this abundance of negative energy to draw upon, Vigo displayed characteristics and abilities comparable to a Class 7 entity, such as Gozer. During this time, Vigo performs remarkable feats of telekinesis, telepathy, and mind control. Additionally, he withstood an attack from proton beams, and even managed to viciously retaliate against the Ghostbusters, leaving them temporarily paralyzed. He also has the ability to shape shift into a more demonic form, complete with horns and blood-red eyes.
In an excluded scene from the Ghostbusters' investigation of the restoration studio, Egon Spengler states the P.K.E. levels were "max-plus" and the Giga meter was showing all red to which Winston Zeddemore bet were readings off of Vigo.
The year before the Poso incident, the Ghostbusters battled Vigo. Egon Spengler collected some of the Psycho-Reactive Slime in the aftermath. In the Poso incident, Egon utilized the last of the slime to disguise Peter Venkman as a ghost and gift him with limited powers such as flight. 
The encounter with Vigo was however chronicled in the comic book adaptation of the second movie by NOW Comics. In this comic, the live action Ghostbusters were replaced with their animated counterparts. It also contained the first appearance of Louis Tully and the only appearance of Dana Barrett in a The Real Ghostbusters continuity.
He was also the main villain in an adventure based on the second movie in a re-issue of the role-playing game. To defeat his defenses in order to approach him, the players had to utilize effigies of The Tinman, Scarecrow and Cowardly Lion from Frank Baum's "Oz" series. When Vigo's painting melts, the Oz characters are shown instead of the Ghostbusters. 
The huge Vigo self-portrait turned out to be the biggest design problem. Industrial Light and Magic (ILM) did concept versions for months and Ivan Reitman felt one was too 'Conan the Barbarian' so artists in New York were brought in. The new designs didn't work out either. Glen Eytchison and Pageant of the Masters in Laguna Beach were approached. Each year, they brought 60 classic paintings to life with people standing in costume before settings based on the original painting. Gross worked with them on a new design. With a deadline looming, the design was sent to ILM with just two days left to a scheduled shoot. The design was worked on down to the last minute. How the portrait would animate was another issue. Originally, it would just be Vigo talking from the painting. Clay animation and an animated cartoon were considered. Eventually, as the script changed, it was decided Vigo would be brought out as much as possible and the painting would be replaced with a floating head hovering in a columned corridor coated with slime. Wilhelm von Homburg was filmed in front of a bluescreen and then matted over a miniature version of the slimed corridor built by the ILM model shop. After each take, the slime had to be cleaned up and reset. 
The demonic floating head seen after Vigo returns the painting was inspired by preproduction sketches done by Thom Enriquez. Lifecasts were done on Wilhelm von Homburg. Tim Lawrence and Makeup artist Mike Smithson did a variety of altercations in clay like strengthening the jaw line, straightening out the nose, making a more sinister brow, elongating earlobes, and sharpening cheeks. 10-11 versions were done and sent to Ivan Reitman for approval. Once the final was chosen, Lawrence had three weeks. Then it was cut down to one week. Howie Weed from the creature shop wore the makeup for scenes when Vigo was transformed within the painting and when Ray was possessed. 
In the Ghostbusters II August 5, 1988 draft, Vigo was very different than the final version seen in the movie. Both versions shared the plans of world domination and being linked to artwork.
In the draft, Jalmar Litvinov was Vigo the Carpathian, the "mad Abbot of Tsbirsk," a friend of Rasputin, and one of three leading causes of the Russian Revolution. In one 3 day stretch, he caused the brutal deaths of 1500 peasants. 
In the draft, he posed as an immigrant named Jalmar Litvinov. He left Tsbirsk, Russia and arrived at Ellis Island in 1917 (on page 92, it is changed to 1906) with a holy icon he painted, a hinged triptych painted on wood in the Byzantine style, depicting martyrdom of a trio of Russian saints. Notably, the central figure in the trio had a powerfully expressive face. 
In the draft, he freely lives in New York posing as an early to mid-30s musician named Jason Locke. 
In the draft, as Jason, he attends Peter, Ray, and Egon's trial. 
In the draft, Lane and Jason met at a Black Sabbath concert. 
In the draft, the baby's father was Jason (Vigo). After Lane got pregnant, Jason became obsessed with the baby and his attitude changed for the negative towards her. Lane broke up with Jason and after the baby was born, she called the police when he came around again. 
In the draft, Egon took readings of Jason with the Giga Meter during the Sixth Avenue encounter and got 130 GeVs of psychomagnetic force off him. 
In the draft, Vigo's plan was take over the world after the fall of modern socity and when his body died, he would possess his son's body and continue ruling. 
In the draft, Vigo's true form is that of a 'wild-eyed, full-bearded, dressed in heavily brocaded robes and Eastern-style miter of an Orthodox bishop but adorned with symbols of his own twisted religion.' 
In draft, Vigo animates the Statue of Liberty with negative psychomagnetic energy and rides it in pursuit of Lane and their baby. 
In draft, Vigo is dispersed on Wall Street after the Ghostbusters patch their Proton Packs into 500 kilovolt amp Con Edison transmission lines and open fire with 2 million kilowatts of electricity. 
You can get insulted by Vigo if you go up to his Vigo painting in the firehouse and interact with it. Below are all 114 Vigo quotes, with audio pulled directly from the game's data files.
