Colossus

Piotr Nikolaievitch Rasputin, also known as Colossus, is a character from the Marvel comics.

Piotr is a Russian mutant who possesses the ability to transform his body into organic steel, giving him immense strength and durability. Colossus is among the physically strongest X-Men, and is a talented artist.

Personality
Despite his fearful appearance and his hulking powers, Peter/Piotr is a kind and gentle soul, always disposed to help the younger students of the Institute and ready to put his strength at the service of whoever needs it. In the original timeline, the teenage Colossus had a talent for art and somewhat a cheeky sense of humor. He is seen with Flea laughing at a picture he sketched of Iceman and Rogue kissing.

Colossus seems to have an honorable nature as he constantly tries to urge Deadpool to join the X-Men and encouraging him to spare Ajax. He is also extremely respectful to women, choosing not to hurt Angel Dust until he was forced to and also covered his eyes when he saw Angel Dust's breasts. Colossus seems to dislike obscene or explicit displays as shown when he displays a distaste for Deadpool's violent actions and swearing.

Abilities
Like the other Phoenix Five, Colossus was not fit to contain the Phoenix Force, and therefore his powers have been broken. He still possesses the same strength and durability, but he must use a special switch to help control his transformations between flesh and steel.

Organic Steel Transformation: Colossus is a mutant with the superhuman ability to convert the tissue of his entire body into an organic steel-like substance. This substance resembling steel is of unknown composition but appears to be analogous to osmium and to carbon steel. He is able to transform into this armor-like state at will (the process is virtually instantaneous) and remain in that form for an as yet undetermined amount of time. (The longest time he has remained in armored form by choice so far has been five days). Once in his armored form he remains so until he consciously wills himself back to normal. If he is rendered unconscious, however, he spontaneously reverts to his normal form.

While in the armored state, Colossus possesses the same degree of mobility that he does in his normal form. The conversion from flesh and bone to organic steel is accomplished by a psionic whole-brain interface with an ionic form of osmium, an extremely dense metal, located in another dimension. In willing the act of transformation, Colossus actually exchanges osmium atoms for his carbon atoms. The psionic interface with the other dimension re-creates all of Colossus's body in functionally similar organic ionic-osmium materials. The process by which Colossus gains additional mass from an unknown, perhaps extra-dimensional, force remains unknown. Colossus cannot become partially or selectively armored; his body is either entirely converted or not.
 * Superhuman Strength: After transforming into his armored state, Colossus possesses vast superhuman strength. As a teenager, he was sufficiently strong enough to lift about 70 tons. However, as a fully mature adult, his strength has increased to the point that he is able to lift over 100 tons easily. With his brute strength, he has performed feats that include smashing tanks with his bare hands, easily uproot trees, easily throw around 50 feet tall robots, carry the X-Men Blackbird (which has a mass of around 85 tons) all the way to shore after it sunk in the ocean and was almost completely filled with water, and hold a collapsing hospital on his own. His punches have been able to considerably hurt Abomination, and slightly hurt Hulk.


 * Superhuman Stamina: Also, while in armored form, Colossus' musculature produces considerably less fatigue toxins than the musculature of a normal human. At his peak, he can physically exert himself at peak capacity for several days before the build up of fatigue toxins in his blood begins to impair him.


 * Superhuman Durability: In his armored form Colossus is invulnerable to most forms of bodily harm. His armor is capable of withstanding ballistic penetration, including that of a 155 millimeter Howitzer shell. He can survive extremes of temperature from 70 degrees above absolute zero (-390 degrees Fahrenheit) to approximately 9000 degrees Fahrenheit. He can survive a collision with a loaded, ten-ton flatbed truck at 100 miles per hour or an explosion of 4500 pounds of TNT. He can also survive falls from great heights while in his armored body. His durability has also allowed him to take punches from Rockslide without any damage (in fact, Rockslide has broken his hands punching him), withstand optic blasts from Cyclops, and Wolverine has had some difficulty in cutting through his skin with his Adamantium claws (althrough this has been because of Wolverine's brute strength not being sufficient), and he has briefly being able to take punches from Hulk. He has also withstood plasma blasts from Havok and Sunfire. During the events of Second Coming, the Nimrods calculated that it would take (approximately) 750 tons of force to break one of Colossus' arms. He's also immune to electricity, as well as resistant (but not immune) to magic. His density (and by extension, his mass) increase as well in his metallic form.

Former Powers
Avatar of Cytorrak: The Unstoppable Juggernaut possesses the conventional superhuman attributes of an Elder God, however many of his abilities are greater than the average member of his race. Cyttorak grants his godly body to his avatar, the Crimson Gem of Cyttorak then bonds to his avatar's soul and makes him a god, by giving him this new body. However, this body is Cyttorak's original Elder God body instead of his degenerated demonic body, hence it is superior to Cyttorak's current body.
 * Magic:  now being Avatar of Cyttorak Colossus powers are no longer from his mutant powers but from magic, which means no science effects like a nuclear bomb or radiation wave can even affect him.


 * Superhuman Strength: The Juggernaut possesses vast superhuman strength the limits of which are unknown. When Colossus had the powers of Juggernaut, he was strong enough to overpower the Thing and Red Hulk with ease.


 * Superhuman Stamina: Juggernaut's body generates no fatigue toxins during physical activity, granting him limitless superhuman stamina in all physical activities.


 * Superhuman Speed: Despite his immense size, Juggernaut's superhumanly strong leg muscles allow him to run and move at speeds beyond the natural physical limits of the finest human athlete. He can run at speeds of 111 miles per hour or more.


 * Superhumanly Dense Tissue: The Juggernaut's skin, muscle, and bone is exactly 4 times denser than the same tissue in the body of a human being, greatly contributing to his superhuman weight.


 * Invulnerability: The Juggernaut is highly invulnerable to all forms of physical injury. The Juggernaut's skin is almost completely unbreakable and he is highly resistant to pain. The Juggernaut is also immune to all toxins, poisons, and disease.


 * Regenerative Healing Factor: If damaged, Juggernaut possesses a regenerative healing factor that enables him to completely regenerate with superhuman speed. Essentially, as long as there is a molecule of Juggernaut's body, a molecule of the power of the Crimson Gem of Cyttorak still upon him, and he is still the Exemplar of the ruby, the Juggernaut will regain his full power and be completely healed, suggesting nothing is drawing or blocking the gems mystical energies or all of the energy from resonating and becoming one again.


 * Self Sustenance: The Juggernaut is completely self sustained. He has no need to breathe, eat, or drink and cannot tire, hence he cannot sleep. However, his self generating mystical energies provides him with the nourishment of sleep, nutrition, hydration, and oxygen. He is sustained by his mystical energies alone.


 * Immortality: Juggernaut is immortal. He is not a millisecond past his absolute physical prime and is immune to aging. Nothing except perhaps total molecular disintegration can kill him.


 * Force Field: The Juggernaut is capable of generating a personal force field around himself, extending to about 1 foot in diameter from his body. He uses this force field for many purposes, such as preventing physical contact, keeping debris and unwanted materials off himself, erecting his force field to escape piles of debris easier, and a few other purposes as well. However its most important purpose is the fact that if he is cast in concrete or other materials, for example a plane dropping a large amount of solidifying material that can put his body in a hard cast, or falling into wet concrete that would harden around him in a full body cast which would keep his motion prohibited, he can erect this force field to break out of a cast. Hence, without this force field he would not be unstoppable. The force field is also particularly resistant to such materials in the first place, as they would slide off much faster and more smoothly then from his body alone due to the fact it is pure energy. Also, his force field can resist mystical attacks better then the Juggernaut could do alone, as it is energy created from his actual power. Mystical weapons that can hurt Juggernaut have to penetrate his force field first, making it even more useful, not to mention the force field being able to produce more energy to continually push out an intruder that has managed to break into his defenses.


 * Demon Form: When in states of heightened emotion Colossus will further mutate into a form more resembling Cyttorak. This includes spikes, scales, claws and red eyes. In this form Colossus appears to be stronger and more aggressive.


 * Embodiment of Irresistible Force: Once the Juggernaut begins to advance in a certain direction, it is virtually impossible to halt his movement. Some obstacles such as many tons of rocks and plasma-discharge cannons have slowed his pace but can't completely halt him. The only known examples of him being stopped involve physical force with mystical involvement, which is Juggernaut's sole weakness.

Phoenix Force
Phoenix Force: Colossus was one of five avatars of the Phoenix Force which granted him the great powers of the Phoenix. So far Colossus has shown greater brute strength and durability than ever before, being capable of taking punches from Gladiator without any damage, as well as punching him back with enough strength to smash his face easily. As an avatar he should presumably possess the following abilities as well:
 * Interstellar Travel: A Phoenix Force avatar can fly unaided through the vacuum of space, and can travel interstellar distances faster than the speed of light


 * Cosmic Pyrokinesis: An Avatar of the Phoenix can create 'cosmic' flames under any conditions even the impossible ones such as vacuum space or underwater. These flames do not require oxygen to burn, and burn so intensely that matter is consumed without by-products such as ash. It has perfect control over these flames, and they only consume what it wills. Typically they manifest as a raptor or part of a raptor such as a claw or wings, in the case of an avatar.


 * Resurrection: As the embodiment of all life and death itself, the Phoenix Force can resurrect whomever it desires into pure living flesh, bone, and blood.


 * Immortality: The Avatar of the Phoenix does not age and can be resurrected by the Phoenix Force.


 * Temporal Manipulation: An Avatar acting as the Phoenix Force can manipulate the past across large temporal distances and with a profound knowledge of the causal effect his or her actions will have.


 * Telepathy A Phoenix Force Avatar can project their thoughts into the minds of others and read other peoples thoughts at a near boundless level.


 * Telekinesis An Avatar of the Phoenix can control and manipulate matter at a molecular scale.
