— Sonic the Werehog, Sonic Unleashed

Sonic the Werehog (ソニック・ザ・ウェアホッグ Sonikku za Weahoggu?) is a transformation that appears in Sonic Unleashed. A bestial, werewolf-like form of Sonic the Hedgehog, this transformation was created when Sonic accidentally absorbed a large dose of Dark Gaia's energy onboard the Chaos Energy Cannon, although the transformation itself would only be triggered by nighttime and remain active until daytime. Sonic eventually lost this form permanently when Dark Gaia reclaimed the energy that caused the transformation.

Concept and creation

Early art of the Werehog was made by a Sega member named Tanahashi. He changed Sonic's general form into something more strong looking. The shoulder and the head are connected by a single line, and his chest is much more broad, giving his body the appearance of an inverse triangle. The final design, he said, was a "silly design"; it was made when he was getting started with the Werehog. He based the design to that of a Yeti.[2]


In this form, Sonic resembles a werewolf and gains more muscle mass and weight. He grows slightly larger, with a broader torso, a longer muzzle, larger hands, and longer, more muscular arms. Additionally, his finger nails become claw-like and his teeth become fangs. Likewise, his ears become more curved and thin, and his lips become black. His once peach skin is now a pale blue. His fur grows into a lush, heavy, dark blue coat. He also gains fur in places he normally does not, such as on his arms and chest. Traits of white fur also appear on his wrists, the end of his quills, and on his chest.

For attire, Sonic loses his white gloves, exposing his hands, and the cuffs of his shoes become slightly frilled in the back. His now dark red shoes have gray metal strips that have three spikes on the surface, and the bottom of each of his soles are covered with eighteen small metal spikes.


Sonic gained this form for the first time when Dr. Eggman used a machine to forcefully extract the power of the Chaos Emeralds from Super Sonic, with which Eggman fired a specialized laser weapon at the planet, releasing and awakening Dark Gaia from the core of the planet. During the process, due to Sonic's close proximity to the Chaos Emeralds, some of Dark Gaia's energy infested his body, causing his transformation into the Werehog. The transformation is triggered at night, which is when Dark Gaia's presence can move freely and affect people. When transforming into the Werehog (or transforming back to normal), light and a cloud of purple smoke envelops Sonic.

Sonic the Werehog features a much different gameplay style than Sonic's normal form: a beat-em-up platformer. He attacks with his arms and fists, which can stretch out and hit his foes, instead of ramming into them at high speeds. In nighttime stages, Sonic loses his speed and must fight through swarms of enemies with his increased strength. Rather than using a counted number of rings, Sonic uses a health bar, where collecting rings refills the bar. The Werehog must cross some gaps in a tight-rope walking fashion.

Sonic retains most of his normal abilities and personality in this form as well as the ability to speak, though with more of a growl than normal. It appears, however, that Sonic gains some minor bestial behavior while in this form, as he howls like a real wolf at the beginning of a night stage, during the Dark Gaia Phoenix boss fight, or upon getting an A-rank or S-rank. He can also run on all fours like a real wolf and fight in a more vicious way than his normal self. Therefore, it can basically just be considered a darker, more feral form of Sonic rather than a split-personality monster like other interpretations of werewolves. Despite this, however, Sonic the Werehog still has Sonic the Hedgehog's good heart. This is primarily due to his will, which, according to Chip, is too strong for Dark Gaia to control in any way.

Before the final showdown with Dark Gaia, Dark Gaia re-absorbed the remaining power that Sonic had incidentally taken at the start of the game, stripping Sonic of his Werehog form for good.

Other game appearances

Sonic Runners

In Sonic Runners, Sonic the Werehog was a playable Power Type character. In gameplay, he could perform a midair dash attack and boost the Distance- and Animal Bonus score by 37%. Also, like all Power Type characters, he had the ability to perform a midair dash attack.

Super Smash Bros. Ultimate

In Super Smash Bros. Ultimate, Sonic the Werehog appears as an Advanced class Neutral-type support spirit that can be summoned using cores from the Togedemaru and Werewolf spirits. Once he has been summoned for the first time, he will start appearing on the Spirit Board where he possesses a puppet fighter based on Wolf. When equipped to a spirit team, Sonic the Werehog increases the power of a fighter's physical attacks.

Powers and abilities

Due to his transformation giving him increased muscular density,[3] Sonic gains a noticeable increase in physical strength, allowing him to open sealed doors and entrances; effortlessly pick up, throw, and swing large enemies and objects; destroy metal vaults with one hit; and even topple creatures several times his size, such as Titans and the Dark Gaia Phoenix. While he loses his trademark super speed, Sonic can still run faster than the average human by dashing on all fours. He also retains his normal lightning fast reflexes and agility, and a small degree of his jumping skills.

In this form, Sonic is able to stretch his arms over long distances in an instant. It is unknown how far he can stretch his arms. Sonic mainly uses this ability in combat, allowing him to increase his attack range, grab enemies from long distances, build momentum for his attacks, and create various forms of combat moves with the energy of Dark Gaia. He can even enlarge his arms, hands and feet to increase the power and range of his attacks even further. Besides combat, Sonic can also use this ability to travel around, such as grabbing onto ridges and swinging from pole to pole.

Sonic the Werehog is capable of harnessing the energies of Dark Gaia, possibly due to the creature being the source of this form, for different applications. He can apply it in hand-to-hand combat to empower his attacks, put up a powerful energy shield when guarding, and harness excess Dark Gaia Force. Gathering up enough of this energy allows Sonic to enter his Unleashed Mode, a temporary state that increases his strength, speed, and durability.

Techniques and Moves

Sonic the Werehog uses a type of feral hand-to-hand combat to fight his enemies. Basically, when using his fists, Sonic can deal greater damage, but only in a focused area and when using his claws, he can attack several opponents at once, but the damage will be much less.


In this form, Sonic is slower compared to his normal form, which makes him less able to outrun his foes and forces him to adapt a new fighting style. Sonic is also unable to control this transformation, since it automatically activates and ends according to the sun. He also cannot grind on rails, due to his lack of speed. The Werehog also often fails when trying to communicate with humans, since people usually are afraid of him because of his appearance, and therefore he cannot be very social. This takes a toll on Sonic, making him feel depressed and somewhat unable to face those he knows, as seen when Amy does not recognize him while he was a Werehog. Sonic also gains a sort of temper in this form, as seen in Sonic: Night of the Werehog.

In other media

Archie Comics

Sonic the Werehog, from Sonic the Hedgehog #279.

Sonic the Werehog has also appeared in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. His first, albeit non-canon, appearance was in Sonic the Hedgehog #193, during the brief Sonic Unleashed adaptation which took place in the "In Another Time, In Another Place" reality.

Sonic the Werehog's first "true" appearance was in Sonic the Hedgehog #264, shortly after Sonic the Hedgehog came into contact with some concentrated Dark Gaia Energy. Each time under extreme stress following that, Sonic would start transform into the Werehog, only for it to subdue. When caught by the Soumerca Egg Army however, Sonic finally turned into Werehog and briefly lost control. After receiving training from Moss the Sloth though, Sonic gained control over his Werehog form.

  • Sonic's gloves were torn apart during the first transformation. Because of this, Sonic the Werehog is one of the few non-robotic characters to not wear gloves.
    • Oddly, when he turns back into normal Sonic, his gloves magically repair themselves. In the Xbox 360/PlayStation 3 version of Sonic Unleashed, Chip will even acknowledge this if the player feeds him enough food by asking, "Where do you put your gloves at night?"
  • In the game, Lambros notes Sonic as being "shorter and stouter than before." However, Sonic grows almost a whole foot taller in his Werehog form, from 100cm (3'3") to 125cm (4'1").
  • Sonic the Werehog is based on the famous mythical creature the Werewolf.
    • Despite the term "Werehog" being a portmanteau of "werewolf" and "hedgehog," it is actually a misnomer. The word "werewolf" is the modern English continuation of a late Old English "wer(e)wulf," a compound of were "man" (cognate with Gothic wair, Latin vir) and wulf "wolf"; cognate with Middle Dutch weerwolf, Old High German werwolf. The term is literally "man-wolf," a man who becomes a wolf. Consequently, the term "Werehog" would literally mean "man-hog," an inaccurate term that would imply a man who becomes a hog rather than a hedgehog who becomes a wolf.
    • In actuality, a more accurate term for Sonic's lupine-like transformation would actually be "ílwolf" rather than "Werehog," as the Old English word íl means "hedgehog." Incidentally, the words "hattefagol" and "hærenfagol" are alternative Old English translations for "hedgehog."
  • Due to this form's unique traits, Sonic the Werehog could be considered a hedgehog/Dark Gaia's Minion hybrid.
  • Sonic the Werehog's ability to stretch and extend his arms is a trait that several of Dark Gaia's Minions possess, especially the Nightmare variant. This might be due to Dark Gaia's energy being the source of both Sonic the Werehog's and Dark Gaia's Minions' powers.
    • Additionally, the Nightmares are shown to guard like the Werehog, as well as execute the Wild Whirl.
  • Sonic the Werehog is the second of Sonic's transformations to have a profile on Sonic Channel, the first one being Super Sonic.
  • In the Xbox 360/PlayStation 3 version of Sonic Unleashed, if a player would press the jump button just as he grabs a ledge, the Werehog would perform a spin jump similar to Sonic's.
    • This also happens when releasing a horizontal pole, grabbing an enemy while in midair, and jumping while sliding down a slippery path.
  • Sonic the Werehog is not the first character created by Sega to have elastic/stretchy arms: Ristar, another character conceived around the time of Sonic the Hedgehog, was the first in his 1996 debut Ristar the Shooting Star.
  • In 2009 a Sonic costume pack for Little Big Planet was released with a Werehog costume along with the Sonic, Tails, Knuckles, and Eggman costumes.
  • Sonic fought the Egg Dragoon as the Werehog at night. But moments later, when Dark Gaia becomes Perfect Dark Gaia, Amy states, "It was broad daylight a minute ago!", implying that it had been day for several hours. Amy was in Shamar, which is east of Eggmanland on the map screen, so it was at least sunrise in Eggmanland. If this is so, Sonic probably should not have fought the Egg Dragoon at night.
    • Granted, he was far underground, away from the sun, and near a large amount of Dark Gaia energy.
  • In the opening of Sonic Unleashed, Sonic the Werehog's fangs are noticeably sharp, defined, and smooth. However, for the rest of the game, his fangs appear shorter and more in line with the rest of his teeth.
  • The Werehog's standard battle theme song is referred to as "The Battle: Theme of Werehog" in the PS2/Wii versions of Sonic Unleashed.
  • As far as the Japanese dubs of the games are concerned, since the Werehog is voiced by Tomokazu Seki, this marked the first time in a Japanese dubbed 3D Sonic game, that Sonic was voiced by somebody other than Jun'ichi Kanemaru, his regular Japanese voice actor for more than 20 years.
