Sonic the Werehog

Sonic the Werehog (known by some fans as "Werewolf Sonic", "Nightmare Sonic", or "WereSonic") is Sonic's bestial form in the game Sonic Unleashed. Sonic the Hedgehog was transformed when Dr. Eggman used a machine to painfully suck out the power of the Chaos Emeralds in its entirety from Super Sonic, with which Eggman would fire a specialized laser weapon at the planet, releasing and awakening the creature known as Dark Gaia from the core of the planet. It is stated in-game that it is Dark Gaia's power that causes Sonic's nightly transformation into this form.

Sonic transforms into the Werehog at night, which makes his quest more complicated. When transforming into the Werehog (or transforming back to normal), a cloud of purple smoke envelopes him. Sonic the Werehog also features a different gameplay than Sonic. He attacks with his arms and fists, which can stretch out and punch his foes. Rather than using a counted number of rings, Sonic uses a health bar, collecting rings refills the bar. Aside from the usual ability of Sonic being able to race down ramps throughout the levels, in Werehog form you must get across gaps in a tightrope walking fashion.

Sonic appears to retain most of his normal abilities in this form as well as the ability to speak, though with more of a growl than normal. Therefore, it can basically just be considered a darker, feral form of Sonic's rather than as a split-personality monster like other interpretations of werewolves. Sonic the Werehog still has Sonic the Hedgehog's good heart, even though he is in a wolf-like form. This is primarily due to his will; it's too strong for Dark Gaia to affect.

In the mini-movie Sonic: Night of the Werehog, Sonic the Werehog unknowingly gained the affection of a female ghost that two male ghosts were trying to impress.

Before the battle with Dark Gaia, Dark Gaia reabsorbed its remaining power that Sonic had incidentally taken at the start of the game, returning Sonic to his default form. Sonic the Werehog may appear in future games.

Trivia

 * The Werehog's ability to stretch his arms to be used for combat is similar to that of Ristar (although Ristar only used said ability to grab opponents). Some fans consider that the Werehog's stretching arms could also be from the character Monkey D. Luffy from the anime/manga One Piece.
 * One can say that the transformation in itself, especially with the full moon, is similar to the Oozaru from Dragon Ball Z.
 * It may also be a reference to Wolf Link from The Legend of Zelda: Twilight Princess, as a dark substance transforms the hero into a beast.
 * This form was caused by the negative energy of Dark Gaia infecting Sonic.
 * This is the first forced transformation in the games, unless one counts Darkspine Sonic as a forced transformation.
 * Sonic the Werehog is the third Sonic character to get a Sonic Channel wallpaper after his first apperance, the other two being Silver the Hedgehog and Chip.
 * SEGA have officialy announced that fans have not seen the last of the werehog, implying he will appear later on.
 * His voice resembles both Jet the Hawk and Shadow the Hedgehog, as they're all played by the same voice actor.
 * Due to Sonic's gloves getting torn up, Sonic's hands might be blue. That may not be a possibility, as they could also be peach due to the arms that connect them when normal. Also, Darkspine Sonic's hands are a shade of blue, so it is most likely.
 * The werehog is coool. Even though if you get him angy or in rage he`ll attack you( if your a bad guy like Eggman or Dark Gaia). In other words he can be a really layed-back adduitude dispite the way his face looks. I`m work on a story about him aud his new sister Meme the hedgehog and werehog. Trust me I`ll try to have it out really soon.
