Nazo the Hedgehog is a manifestation of negative chaos energy and the main antagonist of Sonic: Nazo Unleashed. Nazo originated from the original trailer for Sonic X where he appeared for a brief moment, but he never ended up making an appearance in the series and the mystery behind him led to him becoming extremely popular. He will return in Sonic: The Wrath of Nazo, the upcoming sequel to Nazo Unleashed.
Nazo appears as a hedgehog similar to Sonic and Shadow, he is bluish-white in color and possess a glowing white aura. In his initial appearance in Nazo Unleashed, he wore red and blue shoes with Super Sonic-esque quills. In The Wrath of Nazo, he will have black shoes with blue stripes, yellow armbands, and a yellow, black-lined triangle on his chest.
Sonic: Nazo Unleashed
Four months after the events of the Shadow the Hedgehog, Nazo appears from out of a Chaos Emerald due to the build up of negative energy within it. He immediately steals the Master Emerald and then goes to collect six of the Chaos Emeralds, destroying Metropolis in his rampage. Nazo then heads to the badlands of South Island in search of the last Chaos Emerald.
Tails and Knuckles find Sonic running in the desert and tell him of Nazo's rampage and the trio goes off to the badlands themselves where they find the Master Emerald and six of the Chaos Emeralds, but Nazo appears immediately thereafter. Knuckles attacks him from underneath, but Nazo heals his wounds quickly. Knuckles then powers up and tries to punch Nazo, but he is defeated by a simple backhand by the hedgehog. Nazo then attacks Sonic, who easily dodges his attacks with his speed. However, Nazo gains the upper-hand using Chaos Control to teleport above Sonic and knock him into the ground. Nazo then attempts to finish Sonic with another blast. However, Shadow saves Sonic before he can be killed. Shadow then confidently attacks Nazo and the two have a clash of Chaos powers. Shadow appears behind Nazo, holding a pistol to his head, but is immediately incapacitated by Nazo, causing the last Chaos Emerald to fly from Shadow and land next to the others, allowing the seven emeralds to come together.
Nazo mocks the fact that Shadow claimed to be the Ultimate Life Form, and goes to attack Sonic again, but is stopped by Tails when the latter uses a blast from his energy cannon. Annoyed, Nazo brutally blasts Tails, grievously wounding him and causing Sonic to transform into Dark Sonic due to the seven emeralds all being together and responding to Sonic's anger. Nazo attempts to fight Dark Sonic, but is overpowered by Sonic's power. However, Sonic comes to his senses and realizes that Dark Sonic can't truly defeat Nazo and thus uses the positive energy to transform into Super Sonic, waiting to confront Nazo.
Later on, Nazo recovers and reappears to engage Sonic in battle once more, only to find him in his super form. He briefly mocks Sonic' use of his super form, only to suffer a barrage of Sonic's attacks. Nazo then rights himself and clashes with Super Sonic, showing his full power in his base and eventually managing to outmatch him in the battle. With Sonic of commission, Shadow attempts to ambush Nazo but is knocked down. Shadow becomes Super Shadow, and Nazo and Super Shadow begin to fight relatively evenly, though Nazo has a slight upper-hand. Shadow manages to get an opening and uses an incredibly powerful and rapid assault of Chaos Arrows before finishing with a Chaos Spear, causing a large explosion.
However, the bloodied Nazo heals from the attack. Sonic turns back into Super Sonic, and the two attack Nazo together using the super version of Light Speed Attack. Nazo cannot follow their movements and is beaten down by their combined powers and abilities, and the duo eventually blasts him into a crater and momentarily defeat him. As Sonic is celebrating with Knuckles and Tails - who had been healed by Knuckles using rings - Nazo quickly grabs all of the Emeralds and takes them to Angel Island, causing it to float into the sky, and leaving Sonic and the others to pursue him.
Nazo stands atop the Master Emerald with the Chaos Emeralds at the Angel Island emerald alter as Sonic, Shadow, Tails and Knuckles appear via Chaos Control. Nazo tells them they are too late to stop him and explains his origins as a being of negative chaos, having slowly formed inside the Chaos Emeralds due to the build up of negative energy from beings who used them for negative purposes, such as Dr. Eggman, Chaos, the Biolizard, and Black Doom.
Nazo states he will use the power of the Chaos Emeralds and Master Emerald to go beyond the strength of a god. Using the Chaos Emeralds and Master Emerald, Nazo then transforms into Perfect Nazo. Sonic becomes Super Sonic and attacks Nazo, but is unable to deal any damage to Nazo. Not willing to give up, Sonic tries to continue, but he is quickly knocked out by a Chaos Flare. Shadow becomes Super Shadow and uses Chaos Control to speed up his movement, but Nazo responds with his own Super Chaos Control, slowing down time, before blasting him out of the air.
Though it appears he's been defeated, Shadow removes his limiter rings and transforms into Chaos Super Shadow, grabs Perfect Nazo by the throat, teleports him into a cliff-side, then releases a point blank Chaos Blast, consuming the island and reverting Shadow to base. However Nazo is unharmed, and when Shadow asks who he is, declares that he is the Ultimate Life Form, and knocks the black hedgehog into Sonic. Nazo then mocks the two hedgehogs as the planet's only defense to stop him. Beaten, Sonic and Shadow then remember their friends, Tails, Knuckles, Amy, Cream and Cheese, Rouge, and E-123 Omega, subconsciously tapping into the power of the Chaos Emeralds and Master Emeralds. With the Chaos Energy that transforms the Chaos Emeralds into the Super Emeralds, they transform into Hyper Sonic and Hyper Shadow before using Chaos Control - performing Chaos Unification into one being: Hyper Shadic.
Perfect Nazo laughs - declaring that they are only delaying the destruction of the universe - but is unexpectedly overwhelmed by Shadic's power. Hyper Shadic and Perfect Nazo power up and begin fighting. Nazo uses Chaos Control along with Shadic, and the two fight in the time-stopped plane. Shadic is knocked back, but attacks with the Light Speed Attack, outmatching Nazo with his speed. Nazo's Perfect Eruption clashes with Shadic's Chaos Wind and the two continue to fight. Shadic knocks Nazo into an asteroid, and Nazo responds by knocking him into the moon. Shadic uses Chaos Control and then Spin Dashes to knock Nazo back to Earth.
Nazo shows to be exhausted while Shadic is seemingly fine. Shadic is sure of himself, but Nazo questions how many rings he has left, causing Shadic to lose his confidence immediately. He then reveals that since Sonic and Shadow had turned the Chaos Emeralds into Super Emeralds, it had amplified the amount of negative energy, which Nazo then absorbs, turning him into Hyper Nazo. Nazo then explains his goals, he is naturally inclined to obtain as much power as possible and in time will have more energy than any universe, but that he will never have the infinite energy of the Master Emerald and thus he will detonate Earth, shattering the Master Emerald into thousands of pieces and making it impossible to restore it.
Shadic tells him there is no way he will let that happen, so Nazo responds by teleporting into the air and prepares his ultimate attack, the "Master Breaker." Shadic absorbs all of the rings in the world to create his Billion Ring Chaos Wind in an attempt to counter Nazo, with everyone giving their rings to Shadic - even the likes of Metal Sonic. The two attacks are fired and clash.
Nazo amplifies his attack and begins to overwhelm Shadic, however Tails and Knuckles turn into their Super states, and Super Tails throws Super Knuckles at Hyper Nazo as Shadic puts nearly all of his power into his attack, Knuckles punches Nazo into Shadic's attack, apparently destroying him, but he teleports out of it unconsciously into the void of Chaos. Nazo is surprised he is still alive, when Hyper Shadic appears before him, Nazo is weakened in the void and so Shadic is able to take back the energy that he stole, reverting him to Perfect Nazo, and turning Shadic into Full Power Hyper Shadic, Perfect Nazo prepares a final attack, declaring that he has had enough, but Shadic reverts Nazo back into his normal form and obliterates him and the void of Chaos.
However, one of Nazo's rings survived his destruction and was picked up by Eggman.
Sonic: The Wrath of Nazo
Many years later, after the events of most of the Sonic games, Nazo is somehow revived by Eggman.
Sonic: The Return of Nazo
In an alternate continuity, shortly after locating Nazo's wrist ring, Eggman was approached by Sonic, but hid the ring from his foe and managed to slink away without Sonic being aware of it. Four months later, Eggman is at his base examining the ring, but the machine malfunctions and the ring explodes to reveal Nazo, critically injured, but survived Hyper Shadic's attack. He begs Eggman to help him and he agrees if Nazo promises to swear his loyalty to him afterwards and Nazo agrees, allowing Eggman to install cybernetics into his body, turning him into Cyber Nazo, possessing greater strength and speed than before, as well as the ability to detect and locate Chaos energy.
Nazo is pleased with the results but then reveals to Eggman he has no intention to obey his commands and attempts to kill the doctor with an energy blast before he flies away and takes the five Chaos Emeralds that were already collected at the base.
Powers and abilities
Nazo is much stronger than Sonic, Shadow, or any of their friends. He is powerful enough to kick Sonic into the ground to create a large crater, knock both Shadow and Knuckles unconscious in one hit, put Tails into a near-death state with an energy blast, as well manipulate Chaos Control and chaos energy without any of the Chaos Emeralds.
His speed rivals that of Sonic and Shadow in their Super Forms and is powerful enough to overpower both of them individually, however he isn't powerful enough to take on both Super Sonic and Super Shadow and is incapable of keeping up with both of them when using the Light Speed Attack in their Super Forms.
It's also worth noting that in the director's cut, Chakra-X says that had Knuckles' Maximum Heat attack connected, it could've done some serious damage but Nazo was simply too fast for Knuckles. He also possesses an incredible healing factor, as any wounds he receives are healed near-instantaneously, but this ability has only been shown in his base form, leaving it up to debate whether he has it any of his other transformations.
- Chaos Eruption - A large red orb of negative Chaos Energy that can be used in the air and on the ground. Nazo used it when he was destroying the city, while fighting Super Shadow, and its Perfect version while fighting Hyper Shadic.
- Chaos Flare - A horizontal beam of negative Chaos Energy. He first used it to brutalize Tails, then again when attacking Super Sonic as Perfect Nazo.
- Chaos Torrent - Nazo fires an upwards beam of negative Chaos Energy. Stronger than Chaos Eruption, but can only be used firmly on the ground. He used it when fighting against Sonic's super form.
- Chaos Control - Nazo can use the power of Chaos Control, but doesn't require the emeralds to use it. Using it he can stop time and teleport with it and in his Perfect form, he had a variant called "Perfect Chaos Control," which makes the normal Chaos Control move at snail's pace in comparison.
- Master Breaker - Nazo's ultimate attack with the intention of destroying both the Master Emerald and the planet it's on, causing it to shatter into thousands of pieces and be scattered across the galaxy to the point where it can never be reassembled again.
Nazo's Super state Super Nazo, which only appears in The Power of Nazo. This form is achieved using the Master Emerald only, in this form he is able to outmatch Super Sonic and Super Shadow, but is quickly beaten by Hyper Shadic. Chakra-X described the form as "green" and "Super Saiyan 2-like."
Using the power of the Chaos Emeralds and Master Emerald, Nazo achieves his true form, Perfect Nazo. He is easily capable of outclassing both Super Sonic and Super Shadow and falls just short of Hyper Shadic in terms of power and speed.
In this form, his fur is red and he gains more quills which are even more spiked than before, along with four golden brace-like rings appearing on his wrists and ankles. His eyes have turned yellow with red iris' and the black shadows on the edge turning blue, along with his shoes turning into a black color with yellow markings, along with his voice changing as well.
Hyper Perfect Nazo
By absorbing the negative energy of the Super Emeralds, Nazo becomes Hyper Perfect Nazo, otherwise known as Hyper Nazo or Ultimate Nazo, becoming exponentially more powerful - more powerful than Hyper Shadic - requiring Super Tails and Hyper Knuckles to make him drop his guard so Shadic's ultimate attack can hit him and even then only managed to weaken him.
This form is very similar to his Perfect form due to this it being an augmented version, the only differences being his braces turning black, his shoes' design changing, and his eyes turning from red iris with blue edges to blue iris with black edges.
Chaos Nazo is another form of Nazo, which he uses after he is revived by Eggman. In this form, he becomes primarily green save for black highlights on his quills, his blue-striped shoes become purple-striped, and a yellow triangle on his chest becomes a purple rhombus. His leg-bands also become yellow.
Chaos Nazo has been teased to possibly be stronger than Perfect Nazo. Chakra-X has also stated that this form is based off of Super Nazo.
Cyber NazoThis is Nazo's new base form in the fan-made sequel, The Return of Nazo.
In this form, Nazo has been enhanced with cybernetic attachments built into his body to save him by Dr. Eggman after tricking him into helping him. These enhancements boost Nazo's power and speed to much greater levels than they were in his original form where he is able to overpower Dark Sonic, as well as the combined power of Super Sonic and Super Shadow; feats that were impossible in his purely organic body.
He also gains new abilities thanks to the cybernetics built into him, such as an energy-powered punch called "Cyber Impact", the ability to create an energy sword, sense others' energy, and can manipulate others' energy techniques.
Appearance-wise, Nazo looks extremely similar to his base, though half his body is covered with blue and yellow armor, and his left eye has been replaced with a device that can detect chaos energy.
