Learn about Sonic the Hedgehog, Chip, Professor Pickle, Dr. Eggman, and other important characters in Sonic Unleashed.
Sonic the Hedgehog
Sonic is a blue hedgehog known for his incredible speed, capable of running faster than the speed of sound. He can curl into a ball to spin and cut through materials like metal. Despite occasional impatience, he is driven to help others and despises injustice. His primary weakness is water; while he can hydroplane at high speeds, he cannot swim. After meeting Chip, Sonic embarks on a quest to restore the planet, the Chaos Emeralds, Chip's memories, and himself.
Other Versions of Sonic in this game
Super Sonic
Super Sonic is a form Sonic assumes when he collects all 7 Chaos Emeralds (and sometimes 50 Rings). In this state, he turns golden yellow, achieves higher speeds, uses enhanced versions of his regular moves, becomes nearly invulnerable, and can fly. This transformation is always temporary.
Sonic the Werehog
Sonic transforms into the Werehog during the Evening due to Dark Gaia's power activating at night. After Super Sonic was used to power the Chaos Energy Cannon, Sonic's body absorbed a portion of Dark Gaia. However, Sonic's strong mind prevented possession, unlike other victims of Dark Gaia's Minions. In this form, his arms are more muscular, and his limbs can stretch. While he cannot break the sound barrier as the Werehog, he can deliver rapid punches and kicks, making it the antithesis of his regular Hedgehog form.
Chip
Chip serves as Sonic's navigator in Sonic Unleashed, accompanying him in the hope of recovering his memories. Despite his amnesia, Chip possesses knowledge of Sonic's abilities and locations, and points out details others might miss. He also has mysterious powers and a strong fondness for sweets, particularly chocolate. As Sonic and Chip work to restore the planet, Chip gradually regains his memories and remembers his true purpose.
Tails the Fox
Tails is Sonic's best friend, possessing an IQ and mechanical skill rivaling Dr. Eggman's. His real name is Miles Prower, nicknamed Tails due to his two tails, which he can spin like a propeller for flight. For long-distance or aerial travel, Tails uses his modified biplane, the Tornado. He was last seen heading towards Apotos.
Amy Rose the Hedgehog
Amy is a pink Hedgehog who believes she is Sonic's girlfriend. Angering her can cause her to enter an "Unleash Mode" and attack with her Piko Piko Hammer, which she can conjure instantly. Her affection for Sonic is so strong that she has mistaken other male hedgehogs for him. She was last seen heading towards Spagonia.
Professor Pickle
Professor Pickle is a professor at Spagonia University and the foremost expert on Dark Gaia. His favorite food is cucumber sandwiches. He was last seen at his Laboratory in Spagonia.
Dr. Eggman
Dr. Eggman, also known as Dr. Ivo Robotnik, is a mad scientist intent on world domination. His plan involves creating Eggmanland as his operational base to launch global attacks. Sonic is the sole obstacle to his ambitions. The question remains whether Dr. Eggman can be stopped now that he has unleashed Dark Gaia and fractured the world.
Orbot
Orbot is a robot assistant recently created by Dr. Eggman. Despite his intelligence, Orbot often gets into trouble due to his talkativeness.
Egg Fighter Series Robots
The Egg Fighter Series constitutes Eggman's primary fighting force in Sonic Unleashed. While some are updated versions of older Badniks, most are new designs specifically created to harass and destroy Sonic.
Dark Gaia
Dark Gaia is a being of dark energy that slumbered within the planet's core. Dr. Eggman awakened it when he used the Chaos Emeralds to split the planet. As it was not the "Time of Awakening," Dark Gaia could not maintain its form, and thus fragmented along with the planet. Its essence is dispersed globally. The sun appears to be the only force capable of countering Dark Gaia's powers.
Other Versions of Dark Gaia in this game
Dark Gaia's Minions
Dark Gaia's Minions are the scattered fragments of Dark Gaia across the planet. When the sun sets, Dark Gaia's powers reawaken, manifesting negative human emotions and actions into these minions. They can also possess individuals, causing their hosts to behave contrary to their nature. Notably, Sonic the Werehog is the only exception, retaining his original personality.
