Horatio Quentin Quack

Dr. Horatio Quack is a Mobian Duck who, following in his late father's footsteps, became a doctor. A personal friend of King Maximillian Acorn, Horatio was appointed Royal Physician, and remained close to the House of Acorn even after Dr. Ivo Robotnik's military coup and disappearances of most of the Royal Family. During his time with the Knothole Freedom Fighters (led by Sally Acorn, who by extension was the most favourite baby Horatio ever delivered), Horatio served on the frontlines, until Max's return, where his time was preoccupied with taking care of him and the rest of the population of the restored Kingdom of Acorn. When all-out-war was declared between the Kingdom of Knothole and the Eggman Empire (led by the late Robotnik's alternate universe double Dr. Eggman), Horatio lost an eye in an explosion caused when he accidentally stepped on a land-mine while tending to the wounded in a battle. Since then, he has given up active frontline duty and now serves as Head Doctor of New Mobotropolis's Tommy Turtle Memorial Hospital.

Service to the Kingdom
When King Max Acorn was turning into crystal, Dr. Quack devised a Dream Watcher that allowed Sonic to enter King Max' mind to stop King Max from continuing to turn to crystal. The device unfortunately emitted a kind of energy that Robotnik was able to track, thus enabling him to locate Knothole. When his wife and children were captured, Dr. Quack became a pawn in Robotnik's grandiose scheme. Fortunately, the plan was foiled, and the doctor was forgiven for his aiding of Robotnik given the circumstances. (StH: #43, #49, #50)

Dr. Quack was labelled Royal Physician once again by Princess Sally, stating his "healing skills will help put our Kingdom back on the road to recovery" and making him a member of the a member of the new Council of governing during King Max's time in recovery.

Due to the incredible recovery made by King Max, Dr. Quack ran a number of tests to satisfy his "scientific curiosity". During this examination, Max informed Dr. Quack the history of the Acorn Dynasty and it's link to the Source of All, the latter explaining his amazing recovery. (StH: #58)

After Prince Elias and Queen Alicia were brought back to Mobotropolis by the Royal Secret Service, the comatose Queen was left under Dr. Quack's care. He explained to the monarchy that due to the Brotherhood of Guardians' cryo-stasis chamber, the queen's health would neither get better or worse, but would keep her in her current condition until Dr. Quack and his health team could figure out a means to cure her ailments.

When Sonic and the Freedom Fighters attempted to explain it was the escapees of the Devil's Gulag who had kidnapped Nate Morgan, this claim was challenged by Geoffrey St. John, as the evidence suggested the escapees had all died. However, Dr. Quack arrived and explained that some of the injured guards of the Devil's Gulag informed him the convicts used a second shuttle to escape. (StH: #70)

Following the loss of Mobotropolis to Robo-Robotnik, Dr. Quack was baffled that Jules and Bernadette Hedgehog has retained their free will while all the other Robians had not. When the two stated it was because of their wedding bands, Dr. Quack said it wasn't scientifically feasible, though Nate Morgan countered this, saying science could not take into account the magical aspects of the Super Emerald, the wedding bands had been forged from its power. (StH: #75, #77)

Dr. Quack was also the one who, with the help of Nate Morgan, developed Bunnie Rabbot's replacement parts that her body's immune system would not reject. Because of this, Bunny survived, but would never be able to be de-roboticized. (SSS: #11)

Following a massive attack on Robotropolis, led by King Max himself, to retrieve the captured Prince Elias, King Max was injured in the attack by a Shadowbot. He was quickly brought before Dr. Quack by Sonic to receive medical treatment. Due to Dr. Quack's medical treatments, Queen Alicia made a full recovery, while Max mostly recovered, though lost the ability to use his legs, thus being confined to a wheel chair.

Treating Famous Patients
Under the leadership of Prince Elias, Knothole was transformed into a more modern city, with a new Castle Acorn being built, as well as a prison, public schools, and a hospital where Dr. Quack was the chief physician. One of his first patients was Kodos, who had been brought unconscious to the hospital by Sonic. Kodos later awoke, went on a rampage and escaped, with Dr. Quack explaining his insanity was caused by prolonged exposure to radioactive toxins in Robotropolis, and that had he not received treatment he would have died. (StH: #91, #99)



One of the next patients Dr. Quack examined was the original Dr. Robotnik, who had been brought back to life from Chaos Knuckles' tampering with the time-space continuum and a device created by Dr. Eggman. Dr. Quack discovered that it for sure the original Robotnik, but did not tell the villain that his molecules would disperse once again without Dr. Eggman's device. Informing the Freedom Fighters of this, the played along with a scheme concocted by Eggman and Robotnik in order to get close to the device and destroy it, thus causing Robotnik to be gone for good.

Dr. Quack later treated Zonic for injuries he sustained from Evil Sonic during the latter's escape. Not long afterwards he examined Sonic, whose speed had been taken away by a Genie and given to Muttski, which Dr. Quack confirmed to Sonic. (StH: #112, #115)

Having been treating both Hershey Cat and Geoffrey St. John for the nanobots that were activated in their bodies weeks ago, Dr. Quack was fascinated when Rotor had managed to heal them completely by creating his own nanobots to attack Dr. Eggman's. He subsequently gave the two a clean bill of health. Not long afterwards, he treated Mina Mongoose for a bullet wound received by Nack the Weasel. (StH: #118, #123)

After the Xorda
Following the Xorda's failed attack, Dr. Quack was forced to become a field agent for the Acorn Kingdom Army as all-out war between the Eggman Empire and the Kingdom of Acorn began after Sonic was transported off world. During one of his field missions, Dr. Quack accidentally stepped on a land mine, causing him serious injuries including a damaged leg (which forced him to use a cane) and the loss of an eye. Following this King Max took him off field mission assignments for good. (StH: #134)

When Sonic returned from outer space, Dr. Quack did a full body examination, and discovered the D'Novulans implant which allowed Sonic to understand almost all languages. He informed Sonic that the implant had begun to bond with his nervous system, and that removing it would do more harm then good, advising him to leave it in as it showed no signs of potential danger. (StH: #134)

Quack was also responsible for treating King Max and General Armand D'Coolette, for the poison which Patch injected into them. Unfortunately, the General had been injected with too much poison and passed away, although Dr. Quack was able to save the elderly king. (StH: #156, #168)

After Hope Kintobor was injured by the Metal Sonic Troopers, Dr. Quack was approached by Sonic and Shadow to give Hope the best medical treatment. Under his care, Hope made a full recovery. (StH: #159)

Following the transportation of all of Knothole's citizens to New Mobotropolis, Dr. Quack patched up Rotor, who had sustained injuries during the attack on Freedom HQ by Snively. He proceeded to examined the only person who had been subjected to the Egg Grape Chambers, Charmy Bee, stating they would not know the extent of his memory loss until some time had passed, but that his health was better than they could have expected. He then examined Sonic, who had sustained heavy injuries battling Eggman's Egg Beater. He explained to Sonic that he healed very quickly due to the residual energies from all the Power Rings he'd used. After Sonic's check-up, Dr. Quack left to spend time with his family. (StH: #177)
