they both should be able to do it without straining too much..... some guy did it once in excaliber (i think ..... Colossus smacked him for kissing Kitty or something.... the guy hit Colossus in the back with some type of energy and melted the area around the base of his spine)
Pete Wisdom did it. Stuck hot knives into Colossus's back. Colossus should be able to handle temperatures around 10,000 degrees Fahrenheit, give or take a 1000. But Torch and Firelord can easily project heat far greater than that. They both melt him.
his armor cant be damaged or melted.he can easily survie a full nova blast....if in x-men he was able to surivive inside the core of a star....100,000 times bigger and hotter then our sun...and was able to take a full blast of gladiator's heat visionfor 3 days with no affects......i think he can survive this punks
Organic steel will not survive the core of a star. No form of steel can.
It damn sure will not survive the core of a star "100,000 times bigger and hotter than our sun."
Someone must be snorting ajax.
Can't be damaged my ass (again, unless you are ONLY referencing a RECENT Colossus). Even back in Uncanny 180ish Pyro heated him so hot that when Avalanche dropped the liquid nitrogen tanks on him he was "frozen," so to speak. Magneto had to physically close all of his wounds in his organic steel form before he reverted back to human else he would have bled to death.
If you go by bios, Firelord could vaporize him, Torch could definitely melt hm. Going by comics... it really is a tossup, probably depends on who is writing him. I'd say they could more often than not. Colossus really needs a healing factor, or greater control over his body's material when in steel form. When you really think about it, with all the people in Marvel who toss around high levels of heat, it's just surprising he hasn't been melted into a puddle already.
