¿Who is stronger, Sandman or Magneto?

Sandman, also known as William Baker, is a fictional character in the Marvel Comics Universe. Created by writer Stan Lee and artist Steve Ditko, Sandman first appeared in Amazing Spider-Man #4 in 1963. Sandman's powers stem from his ability to transform his body into sand, granting him incredible strength and the ability to reshape his form into various shapes and sizes. His sand form allows him to absorb and repel force, making him nearly invulnerable to physical attacks. He can also use his sand form to travel long distances by riding the wind. Sandman's backstory is complex and often tragic. He grew up in an abusive household, and turned to a life of crime as a means of survival. He was eventually incarcerated in prison, where he underwent an experiment that gave him his sand-based powers. Initially, Sandman was a villain and frequently clashed with Spider-Man. However, he has also had periods of heroism and redemption, most notably when he became a member of the superhero team known as the Thunderbolts. One of Sandman's most notable strengths is his ability to control sand and manipulate the environment around him. He can use his sand form to create weapons, shields, and even control the movement of sand around him to his advantage. His abilities also make him a formidable opponent in battle, as he is able to absorb and redirect attacks. Overall, Sandman's powers and strength make him one of the most unique and interesting characters in the Marvel Universe. His tragic backstory and complex relationships with other characters add depth and nuance to his character, making him a fan favorite.

Magneto is one of the most powerful and enigmatic villains in the Marvel Universe. First appearing in X-Men #1 in 1963, Magneto has been a constant thorn in the side of the X-Men and other superheroes for over half a century. Born Max Eisenhardt in Germany, Magneto survived the Holocaust as a child and developed a deep-seated hatred for humanity. He became convinced that mutants were the next step in human evolution and that they should rule over humanity. To that end, Magneto has spent his life fighting for mutant rights and battling against those who would seek to harm or oppress mutants. Magneto's powers are derived from his control over magnetic fields. He can manipulate metal objects, control electromagnetic waves, and even generate force fields. Magneto's powers are among the most formidable in the Marvel Universe, and he has been known to take on entire armies with ease. In addition to his incredible powers, Magneto is also a brilliant strategist and tactician. He has led multiple groups of mutants in various battles against the X-Men and other superheroes, and has even taken control of entire countries. Despite his villainous nature, Magneto has a complex and nuanced history. He has been both a friend and foe to the X-Men, and has even worked with them on occasion when their goals aligned. Magneto's motivations are often driven by his desire to protect mutants, but his methods are often ruthless and uncompromising. Overall, Magneto's superpowers and strength make him one of the most formidable villains in the Marvel Universe. His deep-seated convictions and complex motivations make him a fascinating and enduring character that has stood the test of time.
