¿Who is stronger, Galactus or Colossus?

Galactus is a comic book character created by Marvel Comics and is known to be one of the publisher's most powerful and feared villains. He is a cosmic being who has come to Earth with the goal of consuming planets and becoming the supreme being in the universe. Galactus has a number of supernatural powers, including the ability to manipulate cosmic energy, the ability to control people's minds and behaviour, and the ability to summon cosmic creatures at will. He is also immortal and virtually indestructible, making him a formidable foe for any hero who confronts him.

Colossus, also known as Piotr Nikolaievitch Rasputin, is a superhero from Marvel Comics who first appeared in Giant-Size X-Men #1 in 1975. Created by writer Len Wein and artist Dave Cockrum, Colossus is a member of the X-Men and one of the most powerful mutants in the Marvel Universe. Colossus' superpowers and strength are closely tied to his ability to transform his entire body into a form of organic steel. When in his steel form, Colossus gains incredible strength and durability, making him one of the strongest beings in the Marvel Universe. He can withstand powerful physical attacks, and his steel skin makes him impervious to most forms of harm. One unique aspect of Colossus' powers is that he can transform back and forth between his human form and his steel form at will. While in his human form, he retains his normal strength and abilities, but when he transforms into his steel form, he gains incredible power and durability. Colossus' origins are closely tied to those of the X-Men. He was recruited by Professor Xavier to join the team of mutants who were trained to use their powers for good. Despite his gentle nature, Colossus quickly became known for his incredible strength and courage, using his powers to fight against various villains and threats. Throughout his career, Colossus has had many memorable moments, including his romance with fellow X-Man Kitty Pryde, his leadership role in various X-Men teams, and his pivotal role in many Marvel Universe events. Overall, Colossus' superpowers and strength make him one of the most iconic mutants in the Marvel Universe. His ability to transform into organic steel gives him incredible power and durability, making him a formidable opponent for even the strongest villains.
