Colossus

Colossus's powers and abilities

Organic Steel Form/Metal Exoskeleton

Colossus can convert the tissues of his entire body into an organic, steel-like substance. This substance resembling steel is of an 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. Once in his armored form, he remains so until he consciously wills himself back to normal. While in the armored state, Colossus possesses the same degree of mobility that he does in his normal form.

Superhuman Strength

After transforming into his armored state, Colossus possesses vast, inhuman strength, allowing him to send people flying with one arm, break stone or dent metal effortlessly, and is immune to the strength of regular humans and even most superhumans. Only the Mark X Sentinel's, Angel Dust, and Juggernaut have been able to match him in strength or overpower him. Even without his metal form, he broke through a wall effortlessly with his fist and carry a very large TV under one arm whilst walking. His strength level was roughly 70 tons as a teenager growing up in the USA. In the revised timeline he appears to have trained harder and is older, allowing him to be capable of pressing 100 tons.

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. He was unfazed by touching Rogue and could give her his armor abilities for as long as she touched him, without any visible cost to himself.

Superhuman Durability

In his armored form, Colossus is completely bulletproof and invulnerable to most forms of bodily harm. He can survive extremes of temperature. He can also survive falls from great heights while in his armored body. Unlike most characters, Colossus demonstrates a significant resistance to Rogue's absorption abilities. Most victims are left nearly powerless and weak. Colossus simply shrugged off the effect and immediately used his powers to throw Wolverine at a Sentinel. He is also completely unaffected by Negasonic Teenage Warhead's explosion at full power despite the heavy collateral damage it caused and it knocking out Angel Dust.

Abilities

Skilled Combatant

Colossus is an extremely skilled and formidable fighter. He was able to keep up with the Sentinels and was skilled enough to almost defeat in combat Angel Dust, who is an extremely skilled fighter in her own right. He showed his advanced combat skills with his fight against Juggernaut, outmaneuvering him but was eventually overwhelmed because of his opponents' greater strength.

Physical Education Teacher

Colossus seems to have a good understanding of physical health and diet as he trains the younger X-Men, such as Negasonic Teenage Warhead. This is notable when Colossus advises her on not skipping breakfast and eating a protein bar after a good work out.

Skilled Pilot

Colossus is capable of piloting the X-Jet.

Skilled Artist

Colossus is seen sketching outside the mansion in the first film, he is also seen sketching an intricate picture of Iceman and Rogue having an unfortunate outcome of their kiss.
