Howard was a resident of a parallel universe to that of the 616 Marvel Universe. He was a resident of Duckworld, in which he lived an ordinary, yet quiet life. Things however soon changed dramatically for Howard when a demon named Thog the Overmaster sought to unite all realities into one reality which he would then control. In this event Howard was taken from his world and was transported to earth, in the Florida everglades, which is the site of Earth's nexus of all realities. Dakimh the Enchanter, a sorcerer who was a nemesis of Thog, recruited Howard and the others who were taken from their home realities to fight Thog, a battle which they ultimately won. On his way back to his own world he fell off of the Stepping Stones of Oblivion and fell to Cleveland, Ohio. This event left Howard stranded on this earth, far away from his own reality.
Howard the Duck was created by Steve Gerber and Val Mayerik and first appeared in Adventure into Fear #19 (1973).
Major Story Arcs
Howard the Duck in a World he Never Made
Feeling a stranger in a world he was never meant to be in, Howard wandered the earth. He soon met up with a lovely girl named Beverly Switzler. Beverly took Howard in, so he now had a place he could call home. The two became close friends and even started developing romantic feelings for one another. Howard and Beverly had many and often wacky adventures, often teaming up with the Man-Thing.
A villain named Doctor Angst and the Band of Bland also attempted to unite all realities into one but once again, Howard (with help from the She-Hulk) managed to stop them. Due to Howard's experiences passing through the Nexus of All Realities, a piece of it became stuck within him. The Cult of Entropy wished to destroy the Nexus and so they sought to kill Howard. He was rescued by the Man-Thing who poured himself down Howard's throat so he could merge with the Nexus fragment. He then reformed after being vomited out of Howard.
Another recurring villain was Doctor Bong, an ex-boyfriend of Beverly whom wanted to win back her love. The three of them often clashed, even coming as far that Beverly had to leave Howard and stay with Bong, otherwise Doctor Bong would kill Howard. The two of them eventually reunited and lived together happily once again. They shared an apartment together, with Beverly pursuing modeling/acting, and Howard finding work as a taxi cab driver in order to pay the bills.
Generation X and Daydreamers
Howard briefly became accociated with Generation X when he was picked up by Generation X'ers Chamber and Skin whil they where on their road-trip. Howard joined them back to the X-men Mansion and started living inside the Bio-Dome that was created in the so-called Danger Room of the house. Howard was soon joined by mutants Artie and Leech, as well as Franklin Richards and a love interest to Howard, the alien Tana Nile. This group was eventually joined by the Man-Thing that emerged from the X-mansion's Bio Dome. It was him that teleported the group, now known as the Daydreamers, away and into the space-time adventure of a liftetime.
During their travels, the group, let by Howard, encountered a strange villain named Dark Hunter whom seemed to have it in for Franklin Richards. The group fled from the villain, in the meantime visiting many strange realities. They even attended Howard's former homeplanet known as Duckworld. Eventually, the group faced the Dark Hunter, whom turned out to be Franklin's own fears.The group then returned to their own reality, and soon split up when Howard went his own way again.
More trouble arose however when Doctor Bong of the Band of Bland had Howard transformed into a humanoid rat. A full scope adventure occurred in which Howard and Beverly tried changing him back to his normal 'duck form'. Things became even more troublesome when Howard started smoking from the cigar of the Saint of Therapists, after which he turned into a piece of Dust. Howard found himself transported into a bar full of demons. There he had a talk with a person whom seemed to resemble God. After his talk with this 'God', they walked outside and he changed Howard back to his duck body.
Howard has been through many crazy adventures, ranging from being nominated for president to meeting the X-Men. During the Civil War story arc, Howard tried to register, but, according to the government, he did not exist and therefore they allowed him to bypass the registration-act as well as taxes.
Joining ARMOR and fighting zombies
More recently, Howard became part of a team called ARMOR, which specialized in taking down the earths' biggest threats. In this role, he teamed up with Machine Man to stop a zombie-like virus from taking over the earth. It took the two on a wild time ride, going from the Wild West to the Middle-Ages and right into the far future. They even teamed up with other heroes such as Swift Cloud, Black Knight and Killraven. The team managed to stop the zombie-threat, at least for now.
After these events, Howard left the ARMOR division and teamed up with old friends She-Hulk and Man-Thing as well as with Nighthawk and Frankenstein during the " Fear Itself" crossover. They alliance formed a team called the Fearsome Four.
Howard does not have any real powers other than the fact that he is somewhat good with magic and is a master of the little-known martial art "Quack-Fu".
Howard has used things to give him powers in the past, including a trident that was given to him by Damion Hellstorm and also an iron suit much like Iron Man's.
Howard the Duck (1986)
Howard the Duck had one movie, presented by George Lucas. The movie was no big success, it could even be said it was a flop. In recent years, the movie has however become somewhat of a 'cult classic'.
The movie tells the tale of a duck from a parallel universe, who crashes to Earth. Unknowingly, he will save it. The film's origin is much the same as Howard's origin from the comics. The only character from the comics to appear in the film other than Howard was Beverly Switzler.
