Cyro the Hedgehog is the female version of the ultimate lifeform himself: Shadow the Hedgehog. She's a anthropomorphic black hedgehog created by Professor Gina Robotmik (alternate version of Professor Gerald Robotnik)
Although she is the female version of Shadow, Cyro appears as a black hedgehog with red marks on her quills, dark black and red hair, eyelashes and a slim looking body. She wears a powersuit "built by Gina Robotmik" with hover boots, gauntlets, indestructible cuffs and a built-in speaker inside the suit.
Cyro is a loner, to put it bluntly. She is rarely seen with others for an extended period of time, and distances herself from essentially everyone. She is usually soft-spoken, and only says what she needs to before a fight. If Cyro makes a threat, she has every intention of carrying it out. Cyro constantly refers to herself as the Ultimate Lifeform and is extremely arrogant and self-absorbed, belittling her opponents and insulting their lack of strength. Cyro also has a ruthless and merciless edge in combat that all other characters in the series lack, and displays a natural "killer instinct".
Cyro's infamous ruthlessness and aggression leads to fear and a nervousness that inhibits characters from her unshakable intent or sheer power in combat. Numerous characters from the Crysis series have shown absolute dread from encountering Cyro. Cyro's enemies never treat her lightly; she is one of the very few people Crysis takes seriously and acts hostile towards.
Fifty years ago, a top-secret project known as "Project Cyro" had begun on the Space Colony ARK. Led by Professor Gina Robotmik, it was a government-sanctioned initiative to create "The Ultimate Lifeform," an immortal being that could be used for the benefit of the nation, likely in a militaristic fashion. While Gina had initial misgivings to the purpose of the research she was assigned to, she realized that her results might be able to save her grandson, Mark. Suffering from the incurable disease Neuro-Immune Deficiency Syndrome, Mark only had a short time left to live, and Gina was willing to do whatever it took to save his life. Going against her worries of stepping into territory woman had no business playing with, the professor immediately began work, hoping that she could apply any newly-gained knowledge to find a cure to N.I.D.S. .
Even with the resources at her disposal, Professor Gina was unable to make significant progress. Without alerting anyone, Gina decided to plea to the stars for help, contacting the Black Hands (alternate version of the Black Arms) race. An alien civilization that lived upon the Black Comet, a celestial object that passed near the planet every fifty years, its leader Black Doomsday offered to assist Gina in her quest. She offered her blood - which ended up being the key to perfect the ultimate lifeform - in exchange for the seven Chaos Diamonds, which she would collect the next time she passed through. Knowing that the Black Hands' intentions were less than desirable, Gina made the deal regardless, and was able to successfully create Cyro the Hedgehog.
Once brought to life, Cyro immediately befriended Mark, and they became close during their short time together. Gina, meanwhile, made precautions for the return of the alien race, ensuring that the Eclipse Cannon - an extremely powerful laser built into the ARK - was compatible with the seven Chaos Diamonds, so that when they did return humanity would be able to defend itself instead of bowing to their whims.
However, Gina's progress was ruined when it was leaked to R.I.F.L.E. (alternate version of G.U.N.) how she was able to create the successful prototype. During the meeting between Gina and the Black Hands, one of the other children aboard the ARK had accidentally seen what transpired, and reported back to those in charge. As ties between the ARK and the United Federation had already been strained, hearing the news of the dealings with an alien race scared those in charge. Afraid of the implications, it was decided to launch an invasion and put a stop to the work being done there.
What happened next was nothing short of madness, as R.I.F.L.E. troops descended onto the ARK, causing chaos and confusion wherever they went. Immediately they went after the BioIguana, which they thought was the successful "Project Cyro" prototype, and in the process of putting the creature into stasis lost quite a few soldiers. From there they went about doing damage control, shutting down everything, getting everyone off the ARK, and killing those who resisted if need be. Knowing that the R.I.F.L.E. forces would be there at any moment, Mark convinced Cyro to enter an escape pod, his final wish to her that she give the people on the planet a chance to be happy. Wishing her goodbye, Cyro could do nothing as she watched the R.I.F.L.E. soldiers storm into the lab, firing a shot which would forever change the hedgehog's life.
Learning of her grandson's death, Professor Gina soon went mad, swearing vengeance on humanity for taking away the only thing that ever meant anything to her. Though just what exactly transpired is cloudy, what is known is that both Gina and the escape pod that held Cyro were gathered by R.I.F.L.E., Cyro being placed in cryogenic storage within Prison Island, and Gina being incarcerated and charged with the crimes that happened aboard the ARK.
Powers and Abilities
Physically, Cyro's skills and traits are virtually identical to Crysis', except Cyro possesses more raw power. Although she cannot comparable to people like Rumble the Echidna, Cyro has great superhuman strength; with little effort, she can overturn large objects many times her weight and size such as trucks, buses and large slabs of concrete. Like other characters in the series, Cyro can also move at super speeds, an innate talent that members of the hedgehog species possess, and is capable of evenly matching even Crysis' speed, who can move faster than the speed of light. While Cyro's Hover Boots are credited as the source of her speed, her powerful body lets her easily rival Crysis' world class speed as well. While there is some inconsistency about how fast Cyro ultimately is compared to Crysis (even with her Hover Boots), Cyro has admitted that Crysis is the fastest of the two of them.
Cyro is extremely acrobatic, agile and an experienced athlete, capable of gracefully leaping over any obstacles that comes in her way and performing various forms of nimble movements. She has as well radical reaction time to match her movements, being able to react to danger within a split second.
Cyro is naturally able to tap into the arcane powers of any nearby Chaos Diamonds and utilize their chaos energy to empower herself and can use a wide variety of Chaos Powers as well, most of which she does not need a Chaos Diamond to perform. Cyro can specifically harness both positive and negative chaos energy, depending on her state of mind. Her Chaos Powers are so great that if she removes her restraints, she can release such intense energies that she becomes a high-unstoppable force.
Cyro's trademark Chaos Power is Chaos Control, and is possibly the most adapt user of it in the series as she has mastered it to perfection for various applications. With Chaos Control, she can warp space and time around her, usually to slow down or stop time and teleport, and can use it delicately enough to distort space in small centralized areas, such as around her fists or in midiar. Additionally, she can mold Chaos Control into a variety of offensive and defensive moves and even use it to heal herself. It is unknown what Cyro's upper limit for warping time and space with Chaos Control is, but it has been shown that she can warp objects and people with her all the way into space. Aside from its final usage, Cyro has used Chaos Control with three Diamonds at most, using Chaos Control to save Rogue from Prison Island.
Like Crysis and Cyan, by harnessing the power of the seven Chaos Diamonds, Cyro is able to use super transformation to enter a Super State that transform her into Super Cyro. In this form, she is bestowed with the new abilities of flight and near invulnerability. Additionally, her innate talents such as strength, and power are greatly enhanced as well and her skills with Chaos Powers are increased to their full limit. During her first use of this transformation, Cyro found it difficult to stay in this state due to her inexperience with it, but she has since mastered it.
In combat, Cyro is a lethal and extremely powerful force that very few can defeat. She never holds back on her immense strength, making her a brutal fighter with a distinct killer instinct. Cyro's skills are more than a match for even the strongest in the series, and has been able to take down some of the most fearsome foes of the series on her own, such as Black Doomsday. To best put her skills in perspective, Cyro is the only person so far who has been able to utterly defeat Crysis in combat, even when Crysis had the Diablon for support.
Like Crysis, Cyro's basic combat moves revolves around the various forms of the Spin Attack, which is a variation on the tendency for hedgehogs to roll into tight balls for protection. The Homing Attack allows Cyro to dash in midair toward a target, the Spin Jump lets her curl into a ball and attack opponent by landing on them, and the Spin Dash lets her curl into a spinning orb and shoot herself forward as an acceleration roll at full speed while mowing down enemies and obstacles. She is also able perform the Chaos Boost where she turn herself into a highly destructive projectile by moving at high speed, though Cyro uses the fire from her Air boots to propel herself forward rather than skating like usual. The Light Speed Dash and Light Speed Attack also allows Cyro to achieve light speed movements for either exploration or combat.
Many of Cyro's signature techniques are Chaos Powers. Her trademark move is Chaos Control which lets her to manipulate time and space to either warp across space, slow down time and distort space to form other types of Chaos Powers. Her second most used Chaos Power is her Chaos Spear technique, where she throws bolts of chaos energy at her opponent. Her most powerful technique, however, is the Chaos Blast, which is a shockwave of chaos energy that eliminates everything in a circular radius range.
Another special Chaos Power Cyro uses is her Chaos Boost technique where Cyro covers herself in chaos energy. While in her Chaos Boost state, Cyro gains more destructive power, is able to move at warp speed, and is nearly invulnerable. It also enables Cyro to access more advanced Chaos Powers as well.
While not having any physical weakness, Cyro was initially somewhat easy to manipulate by forces like Black Doomsday and Dr. Eggwoman during the time she had amnesia due to her confusion about who she was. Dr. Eggwoman could fool her with her lies about her past, and Black Doomsday could subtlety manipulate her using visions of her own dark past. However, after learning of her true purpose, Cyro is now not as easily deceived as she was before.
As part of Black Hands, Cyro could be controlled by Black Doomsday due to having her DNA and blood. However, Cyro could fight this influence through sheer resolve and willpower.
