Character Guide

Meet the cast of The Chaos Project! Here you’ll find character names, pictures, bios, and current status. Characters are listed in an extremely general order of importance, which is subject to change as time goes on. Take special note of the characters denoted by an asterisk, which show images that you can’t find anywhere else, made by me. Especially for newly-introduced characters, that should really help you visualize the series.
Warning: This page contains spoilers. If you aren’t caught up, then browse at your own risk.

Sonic the Hedgehog
Bio: This blue speedster needs no introduction. For years, he’s been foiling Eggman’s many devious schemes. When Eggman takes over the world, it’s no surprise that Sonic is the first to fight back, and it’s clear that he is now dedicated to the task of protecting the world from him. Some time after Sonic separated from Shadow, Sonic’s dedication had begun to falter as he became rather indifferent to the world around him, caring more about his own entertainment above all. But Shadow was able to snap him out of it. Even as the main and original character of the series, surprisingly little is known about Sonic’s past. When Eggman first struck on that fateful day in the Green Hill Zone, why was it that Sonic, a young teenager, was all alone, without any family, without much of anything?
Besides his ability to run at mach speeds, Sonic has the ability to attack by rolling into a ball, both in the air and along the ground. He is nimble and athletic, able to do all sorts of stunts at speed, such as rail-grinding, parkour, and swinging from any sort of rope or rail. With the power of all seven Chaos Emeralds, he can transform into the invincible, light-speed Super Sonic. More recently acquired is his ability to teleport through Chaos Control, using at least one Chaos Emerald, though he does seem to avoid doing so if at all possible.
Current Status: Unknown (Season 1 hasn’t started yet)

Dr. Ivo “Eggman” Robotnik
Bio: Dr. Eggman is the archnemesis of Sonic the Hedgehog. Unconfirmed reports place his IQ at 300, making him the smartest man alive. An inventor and a scientist, Eggman has decided to use the machines he invents to acquire power. Using his genius, he created a device which can draw incredible amounts of energy from the Chaos Emeralds, which he used to power his largest army of robots ever, and to take over the world. Given multiple chances to redeem himself, Eggman has proven time and time again that he will never change his ways. He is constantly scheming a way to defeat Sonic…but some of his actions have inferred that he doesn’t want Sonic dead, regardless of how much he gets in the way. Eggman was once referred to as Robotnik, but that changed after his encounter with time-travelling Zero the Hedgehog, after which he believed he began to think bigger, and wanted a name to match. Why doesn’t Eggman want Sonic dead? What are Eggman’s true motives? How else has his past led him to become who he is today?
Eggman’s intellect is spent almost entirely on designing and constructing robots to do his bidding, as well as much larger mechs which he pilots himself. His most common mode of transportation is his hovering Egg Mobile, which has some light weaponry, but more importantly is capable of attaching to and becoming the control system for Eggman’s large mechs.
Current Status: Unknown

Shadow the Hedgehog*
Bio: More than fifty years ago, a brilliant professor by the name of Gerald Robotnik had the dream of creating an artificial Ultimate Life Form, a being of purity to save humanity from itself. Shadow the Hedgehog was born. But when Project Shadow was shut down, and all aware of it executed, Shadow was placed cryogenic stasis, only to be discovered in the modern day by Dr. Eggman himself. Since then, his priority has always been himself, making his loyalty always questionable. Shadow spent some time after the events of Shadow the Hedgehog (2005) serving in the military force, G.U.N.. However, he later deserted under vague circumstances. Now, he is in training with Sonic under Chaos the Hedgehog, learning all that there is to know about the Chaos Emeralds. Shadow’s deep and complicated past can hardly be done proper justice by such a brief summary, and many questions are still left as to just who or what he is. How is it that he is so similar to Sonic, more than thirty years before Sonic was born? What memories, if any, are still lost to him? Which ones might be fake?
The Black Cloak: After his falling-out with G.U.N., Shadow traveled to Westopolis and donned a suit and mask, becoming the vigilante known as Black Cloak. His goal was to strike fear in the heart of King, a crime lord and mechanical genius who had seized power in Westopolis after the Black Arms invasion. In part through the intervention of Sonic and Rouge, King was successfully defeated and arrested, and Shadow abandoned the name of Black Cloak for good. Or did he? 
Shadow is Sonic’s equal in almost every way. His already naturally high speed is assisted by his jet-launching shoes, which also allow him to hover in the air for brief periods of time. Like Sonic, he can attack by rolling into a ball, but typically prefers hand-to-hand or armed combat. His connection with the Chaos Emeralds seems to go much deeper than Sonic’s; he can use multiple Chaos-based techniques, such as Chaos Blast and Chaos Spear, in addition to Chaos Control, which Sonic only learned from him. Super Shadow, powered by all seven Chaos Emeralds, is just as powerful as Super Sonic. Also of note are the Inhibitor Rings worn on Shadow’s wrists and ankles, which allow him to release a dangerous amount of power when removed. By removing them, Shadow has been shown gaining the ability of Chaos Shine, powered by the yellow Chaos Emerald.
As the Black Cloak, Shadow carries small, precise throwing weapons of a shape which viewers may recognize as Shadow’s emblem seen on the cover of his title video game, as well as several other tools on his utility belt, such as a grappling gun and smoke bombs. He has also referenced and displayed a level of precision accuracy which could almost be called inhuman, only unknown prior because he doesn’t typically throw things.
Current Status: Unknown

Infinite the Jackal*
Infinite (2)Fin
Once known as the “Ultimate Mercenary,” Infinite, then under a different name, was the captain of the Jackal Squad, a band of thieves and rogues. Raiding an Eggman base one day, he came across the Phantom Ruby for the first time. Eggman hired Squad Jackal to protect his facility while he studied the Ruby, Infinite as his new test subject. But when Shadow came in on a mission to infiltrate Eggman’s Facility, he destroyed the Jackal Squad, utterly defeating Infinite in the process. Disgusted by his own weakness, he donned a mask to forget the person he once was, and, with the power of the Phantom Ruby, became Infinite. But Infinite was defeated. The Phantom Ruby was taken from him. Now, he has nothing left. Outwardly, Infinite cares for nothing but his desire to watch the world burn. But he was once a passionate person. The Jackal Squad showed great respect for him. And when they were defeated, he swore vengeance for them.
In control of the Phantom Ruby, Infinite’s powers are, as expected, near-limitless. With the power to create virtual replicas of objects, individuals, and even entire realities, Infinite goes far beyond fooling others, his illusions being in every way as deadly as the real thing. He also has enhanced strength, speed, and the power of flight. But even without the Ruby, Infinite is a swift and agile fighter. Quite skilled with the ornate red blade he wielded, he wasn’t called the Ultimate Mercenary for nothing.
Current Status: Unknown

“Rookie” the Wolf (and Bruno the Wisp)*
Hero (2)
Bio: The Wolf was nobody. Growing up hearing stories of great heroes like Sonic the Hedgehog, he could do nothing but watch and dream. Even when war came to his city, he didn’t have the courage to join the battle. Until the battle came to him. Confronted by Infinite, he witnessed an entire squadron fall around him. Though he fled with his life, he resolved to whatever he could to stop it from happening again, joining the front lines of the Resistance. And somehow, he ended up right by Sonic’s side as the war finally turned. Together, he and Sonic defeated Infinite and the Phantom Ruby. Yet still, he seemed to see something in Infinite that no one else did. When the war ended, he left the Resistance on a mission of his own. The Wolf has a kind and heroic heart, with the desire to help anyone in need, now without any fear to stop him. The Wolf never says much. Whether it be from some weight he carries with him, or because of some unknown event from his past, he prefers to speak through his actions. And through Bruno.
Bruno is a Red Burst Wisp that the Wolf met during the war. They quickly became friends, and are now almost inseparable. The Wolf understands Bruno, and Bruno understands the Wolf. And unlike the Wolf, Bruno is rather talkative. This can often lead to Bruno saying the things that the Wolf does not. Bruno is very friendly, but has quite a hot temper. He also has a slight tendency to become distracted.
The Wolf is skilled with many varieties of Wispon, though, especially with Bruno by his side, he seems to prefer the flame-throwing Red Wispon, which also doubles as a sort of portable pet house for Bruno. The Wolf also wields a wrist-mounted grappling gun, which he uses with incredible efficiency, swinging, pulling, and binding his opponents. What the Wolf lacks in natural ability, he more than makes up for in skill and utility.
Current Status: Unknown

Sunlight/Blacklight the Hedgehog*
Blacklight 2
Sunlight the Hedgehog was created 40 years ago as part of a secretive project at the ground research facility called EDEN. Lieutenant Alfred Robotnik, son of Professor Gerald, made him to correct the failures of the original Project: Shadow. Sunlight proved uncontrollable, and escaped from the facility, soon to meet his own demise. But when Eggman meddled in the timeline by sending him a Chaos Emerald, that all changed.
By the present time, he goes by a new name, Blacklight. Shadow clearly knows who he is, and what he’s capable of. But Blacklight seems to know Shadow even better, having spied on him for an unknown amount of time. Blacklight lives secluded and alone, having apparently conquered Eggmanland. Though he has strongly suggested that he wants Shadow dead, it also seems as if he is perfectly willing to work with him. Perhaps this is a facet of his bipolar personality. Or perhaps all that matters to him is proving that he is on the winning side. Regardless of his reasoning, he clearly has his own way of thinking, and his own purpose.
Blacklight has been shown using the power of the Chaos Emeralds to manipulate the elements, including ice, fire, and void. Presumably, he has many similar abilities to Shadow, though he wears no Inhibitor Rings. His design is composed of seven colors, matching the colors of the Chaos Emeralds. In his Super Form, Black Night, his Emerald colors will all change to match the elemental power which he uses.
Current Status: Unknown

Miles “Tails” Prower
Tails (1)
Bio: Tails first met Sonic soon before Eggman’s second attack, and they’ve been best friends ever since. Now only ten years old, he is an essential member of the team, as his knowledge in electronics and machinery is unparalleled, save for Dr. Eggman. The two have been shown to have quite a rivalry, but they have also proven that they can accomplish far more together than either could alone, on the rare occasion that they are forced to work to together in the first place. Tails looks up to Sonic almost as if they were brothers. The two are always worrying for each other’s safety, but they work well together. But much in the same way as Sonic, Tails’ past is a bit of a mystery. He is only a child, and yet the closest thing to a guardian he has ever been shown to have is Sonic. What happened to his parents? And how exactly did he and Sonic meet?
Tails may be smart, but that doesn’t make him a poor fighter. He may not be as practiced at it, but he can attack in many similar ways as Sonic. More importantly, he can spin his twin tails fast enough to provide lift, letting him fly for as long as he doesn’t get tired. By changing the direction, he can instead use his tails to push himself along the ground, allowing him to move quite quickly, though far from Sonic’s speed. He can attack with his tails, but he doesn’t very often. Lastly, he can often be found piloting Sonic’s plane, the Tornado, which has various transformation modes, including a combat-ready mech. At a recent but unknown point, he upgraded the Tornado into a more aerodynamic, combat-capable fighter plane. How did Sonic get a plane, anyway?
Current Status: Unknown

Knuckles the Echidna
Knuckles (1)
Knuckles was once an enemy of Sonic, but he now stands as one of his closest friends. He spends his days fulfilling his duty as the last surviving member of the Echidna race—guarding the sacred Master Emerald—at a shrine on the floating Angel Island. Knuckles has a hot temper, and can be quite gullible at times. Especially when it comes to the Master Emerald. He likes to think of himself as a lone wolf, but when his friends need his help, he steps in without hesitation. Many questions still remain about him. What happened that exterminated the last of his already dwindling race? Did he ever know any other Echidnas before they died? If so, why has he never mentioned it? If not, how does he know so much about his people and his duty? And how does he really feel about it all?
Knuckles is among the strongest of Sonic’s friends, perhaps rivaled only by Shadow (and Zero). The spiked protrusions from his hands, serving as his namesake, make a hit from him that much more deadly. They also allow him to climb walls and dig with ease, skills which are very important in helping him recover the pieces of the Master Emerald when it shatters. Most important to this is his natural mental link to the Emerald, allowing him to locate hidden shards from great distances away. Surprisingly enough, he also has the ability to glide gracefully through the air, though the exact reason why he can do this is unknown.
Current Status: Unknown

Amy Rose
Amy has known Sonic for nearly as long as Tails has. After Sonic rescued her from Eggman and Metal Sonic, she decided to dedicate herself to romantically pursuing him, despite his objections. Amy is a dedicated friend, and will always stand up for those close to her. She is easily angered, having an intense temper. But her belief in the value of friendship is her most important quality. Apparently, some time before the events of Sonic Adventure, Amy had a chance encounter with a time-traveling Zero the Hedgehog, leading to a change in outfit and to the acquiring of her iconic hammer.
Amy is extremely skilled with her oversized Piko-Piko Hammer. Just one swing is enough to destroy almost anything, especially when she’s mad. She is also quite athletic, even able to use her hammer to assist in her aerial acrobatics.
Current Status: Unknown

Chaos the Hedgehog*
Chaos is wise, yet enigmatic. He is in the process of training both Shadow and Sonic about the Chaos Emeralds and the nature of Chaos Energy. He stresses the importance of remaining calm and focused, and emphasizes a focus on meditation. Despite his usual calm demeanor, his ego is the largest of them all. In battle, he constantly taunts his enemies, and has no problem with referring to himself as a god. When surrounded by a well of natural Chaos Energy, he has been shown to have contact with an even more mysterious chorus of voices, referred to only as the “Lords of Chaos.” It is unknown how he is related to them. His history is a mystery, for now…
Chaos has abilities similar to that of Sonic and Shadow. His connection to the Chaos Emeralds is direct, and they grant him abilities like none other, including exact premonition, in addition to the ability of “Chaos Shield,” a simple protective energy barrier. Most incredibly, he has the power to revert to the form of a rainbow-colored Emerald, which Sonic can absorb his power and consciousness through. He is also a strong strategist. The color of his fur changes with his emotions, and he is white for most of the time.
Current Status: Unknown

Rouge the Bat
Rouge always seems to be at conflict with herself. On one hand, she is a self-proclaimed master jewel thief, a criminal and a scoundrel, but a very skilled one. On the other hand, she is employed as the President’s personal secret agent, as well as doing some lesser work for G.U.N.. She has spoken of giving up treasure-hunting, but it certainly hasn’t happened yet. Rouge’s love of jewels is only surpassed by her loyalty to her closest friends, Shadow and Omega. Practically nothing is known of her past. How does a master thief end up becoming a secret agent?
Besides her skill in both treasure-hunting and stealth, Rouge has an incredibly nimble and powerful kick, made lethal by her hard, sharp-toed boots. As a bat, she has a natural ability to fly and cling to walls. She is also quite skilled at digging, an understandable skill for finding treasure.
Current Status: Unknown

E-123 Omega*
Omega was constructed by Dr. Eggman for unknown reasons, but his first assignment was to guard the room in which Shadow the Hedgehog was being held before his reawakening. Left active 24 hours a day for as much as three months with nowhere to go, Omega had plenty of time to contemplate the nature of his servitude. By the time that Rouge discovered him and Shadow, he had already committed himself to the eradication of all things Eggman. He has been working alongside Shadow and Rouge ever since. Though Omega’s origin is relatively straightforward, nothing is truly known about what happened to him before the moment Shadow was awoken. What was he really built for?
Omega is a walking arsenal. Machine guns, missile launchers, and flamethrowers are just a few of the lethal weapons which can be swapped out for his equally deadly claws. He also has built-in jets which propel his movements, and allow him to hover for short periods of time.

Zero the Hedgehog*

Zero is a Chaos-user from the distant past, who was sent on the same mission as Sonic; to gather the Temporal Sapphires in order to fight Chronos. Zero is a strong fighter, though he doesn’t much care for violence. His past is plagued by memories of the horrendous experiments he underwent, first transformed from a simple animal into a sentient being, and then subjected to nearly unbearable tortures. He eventually escaped, but drove away all the others there like himself in the process. He falsely blames himself for the destruction of his world, in an event he knows as “The Chaos War.” Perhaps most importantly, Zero became the first Controller, his very DNA imbued with the power of Chaos, a trait that would be passed on from generation to generation of Controller, eventually reaching Sonic. He and Sonic didn’t get along well together, but eventually became good friends. Zero tends to be quiet and secluded, but he is capable of caring deeply, and he will stop at nothing to help others in need.
Zero has the ability of the spin attack, as seems to be shared by most hedgehogs. He has quite a bit of brute strength. Like Sonic and Shadow, he is a Chaos-user, and he has the power to sense the presence of both Chaos Emeralds and Temporal Sapphires. Janice has suggested that his connection to Chaos runs far deeper than most others, giving him the power of Time Control. Time Control allows Zero to open a space-time rift on his own, as well as manipulating the flow of time around himself, slowing or stopping his opponents.
Current Status: Unknown

Silver the Hedgehog*
In the distant future, Silver lives to protect his world. Once a volcanic wasteland, Silver’s actions in time-traveling to his past allowed him recreate that future, now a practical utopia. Of course, he remembers none of this. All he knows is that he now lives alone, endlessly protecting the future that he loves so much. But he can’t help but think that something is missing in his life. Something that might have been lost in a timeline that isn’t his own… In the past, Silver has been described as gullible, insecure, and naive, and all of this still seems to hold true to some extent. Silver didn’t trust Zero at first, but he eventually gave in to Zero’s insistence, and the two became very close friends.
Silver has the power of psychokinesis, which, while sounding wondrous, has been inferred to be a rather common ability in his time. However, this power is greatly enhanced by his connection to the power of Chaos. He uses his psychic abilities in a variety of ways, such as lifting and moving objects, including himself and others, and creating shockwaves in the air. In a close-quarters fight, Silver is sloppy and reckless. However, when fought from a distance, he is truly a force to be reckoned with, and it’s just no use fighting him. Just like Sonic, Shadow, and Zero, he can use  the Chaos Emeralds, or “Miracle Gems” as he calls them, to access abilities such as Chaos Control. There’s not necessarily any reason that he can’t use the spin attack, but it’s certainly not his preferred method of attacking or jumping.

Minor Characters

The Hard Boiled Heavies
Bio: Gunner, Rider, Magician, Shinobi, and their leader, King. Originally created by the Phantom Ruby in another dimension, these five modified Egg Robos now serve as Eggman’s elite team. Crossing over to this dimension in search of the Ruby that transformed them, they had no intention siding with this Eggman after having betrayed the last. But Eggman didn’t give them that choice. Intelligent and deadly, the Hard Boiled Heavies may each still have a few screws loose from the original transformation.

Lumis the Shining
Bio: Once one of the mysterious Lords of Chaos, Lumis was sentenced to an eternity of silence as punishment for acting out against the will of the rest. However, when Chaos the Hedgehog was sent to Earth, Lumis managed to escape along with him, attempting the same Ritual he failed to complete ten thousand years ago. Though the Ritual was stopped once again, Lumis was granted a second chance, and has since returned to the Lords of Chaos, where he now watches over Sonic and Chaos with vested interest.

Gerald and Maria Robotnik
Professor Gerald, Shadow’s creator, and Maria, his closest friend, lived on the ARK along with Shadow before the the program was forcibly shut down by G.U.N.. Maria was killed by a soldier during that event, and Gerald was executed shortly afterwards. Maria was an extremely compassionate individual, and Shadow often uses her memory as a reminder to be a better person. Less is known about Gerald’s personality, besides that he cared deeply for Maria, and that he was driven mad when she was killed and the project was shut down. Regardless, he still had the planet’s interests in mind before then, having created the Eclipse Cannon in order to defeat the Black Arms invasion he knew would eventually come.

Lieutenant Alfred Robotnik
Alfred was on the ground, reading his father Gerald’s diary when the ARK was shut down, and his daughter Maria killed. When Shadow was ejected from the ARK on that day, it was Alfred who found him. Led to believe that Shadow was responsible for the deaths, Alfred became obsessed with creating a new, better Ultimate Life Form, without the addition of alien DNA. Ten years later, he awakened Sunlight for the first time.

King the Wolf (Wolfric King)
The sworn enemy of the Black Cloak, King took on the persona of a human businessman under the name of Wolfric, all part of his plan to seize power and develop a criminal empire in Westopolis after the Black Arms invasion. His technical genius, used to build his own mechanical prosthetic arm, was also a great component in this plan. The police force of the city was run by robots of his own invention. During the invasion, it was Shadow’s lack of control with a Chaos Blast that led to his injuries and the death of a loved one, leading him to an intense desire for vengeance, and an obsession over the imperfection of organic life. He was eventually defeated, and even in his final on-screen moments swore that he would one day have his revenge.

Janice and Chronos
 Janice and Chronos are mysterious entities from a place outside of normal space-time known as the “Timestream.” Janice was the apprentice of Chronos, the master of time, until she betrayed him, feeling mistreated and underappreciated. Janice was eventually defeated and humbled, and has since returned to work under Chronos. Experiencing time in a different manner than normal, the two have abilities which would be incomprehensible to a normal person, and have an objective understanding of the universe and extradimensional physics beyond any mortal.

Orbot and Cubot
These two shape-themed robots serve as Eggman’s personal servants. Neither of them are particularly intelligent, but Orbot is the older and wiser of the two. Both are prone to crack jokes, and in general don’t take Eggman’s commands very seriously. Surprisingly enough, they are some of the first artificially intelligent robots to remain completely loyal to Eggman. They don’t seem to like him very much, though…
