Steel-hide

Name: Steel-hide
Species: Colossusian
Homeworld: Eezos
Appearance: Steel-hide is a tall and muscular alien with brown skin but can change his skin into a organic steel skin. He wears a black and red bodysuit. The Omnitrix is on his left thigh.
Powers and Abilities: 
Colossusian Physiology: Steel-hide is a Colossusian with the natural 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.
Organic Steel Form: While in the armored state, Steel-hide possesses the same degree of mobility that he does in his normal form, though his endurance and speed are enhanced. 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, Steel-hide actually exchanges osmium atoms for his carbon atoms. The psionic interface with the other dimension re-creates all of Steel-hide's body in functionally similar organic ionic-osmium materials. The process by which Steel-hide gains additional mass from an unknown, perhaps extra-dimensional, force remains unknown. Steel-hide cannot become partially or selectively armored; his body is either entirely converted or not.
Superhuman Strength: After transforming into his armored state, Steel-hide possesses vast superhuman strength. As a teenager, he was sufficiently strong enough to be listed as a class 70. However, as a fully mature adult, his strength has increased to the point that he is listed at exactly class 100.  He was able to hold his own against Golems,  though he usually lacks the raw power to defeat them, such as when he was easily overpowered and knocked out.
Superhuman Stamina: Also, while in armored form, Steel-hide 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. He also does not need to breathe while transformed, but it is believed that he could not survive for long in a vacuum.
Superhuman Durability: In his armored form, Steel-hide has a high degree of imperviousness to injury. His armored form can withstand ballistic penetration, including that of a 110 millimeter Howitzer shell. He can survive temperature extremes from 70 degrees Fahrenheit above absolute zero (-390 degrees Fahrenheit) to approximately 9000 degrees Fahrenheit. He can survive a collision with a loaded, one ton flatbed truck at 100 miles per hour or an explosion of 450 pounds of TNT. He can also survive falls from great heights while in his armored body. Steel-hide armored form cannot rust under normal Earth conditions. Furthermore, his eyes become steel-like and allowing his eyeballs to withstand and deflect even the impact of a .45 caliber bullet.
Peak Human Speed: In his armored form, Steel-hide's speed is at the peak of human potential, enabling him to run 32-36 mph.
Weakness: 
Vibranium: Steel-hide's metal skin is vulnerable to the anti-metal Vibranium. For example, Xavier stabbed Steel-hide's arm with a Vibranium blade which instinctively turns him back into his normal form.
Adamantium: Steel-hide can also be vulnerable to Adamantium. He can be damaged when he is attacked by something made from or bonded with a stronger material.
