¿Who is stronger, Thanos or Quicksilver?

Thanos is a powerful and malevolent character from the Marvel Universe, first appearing in the Marvel Comics series "The Invincible Iron Man" in 1973. He is a powerful alien warlord from the planet Titan, and is one of the greatest threats faced by the Marvel Universe. Thanos' story begins on the planet Titan, where he was born as the son of Eternals A'Lars and Sui-San. From a young age, Thanos was obsessed with death and the pursuit of power, and he quickly rose through the ranks to become one of the most feared and respected figures in the Marvel Universe. As a result of his Eternal heritage, Thanos possesses a number of superhuman abilities, including strength, speed, agility, durability, and regenerative powers. He also has access to advanced technology, including a suit of armor that enhances his physical abilities and a number of powerful weapons, such as the Infinity Gauntlet. The Infinity Gauntlet is a powerful artifact that allows Thanos to manipulate time, space, and reality itself. With it, he is able to erase entire galaxies from existence, and has even been able to defeat some of the most powerful beings in the Marvel Universe. Throughout his long and storied career, Thanos has clashed with many of the Marvel Universe's greatest heroes, including the Avengers, the Guardians of the Galaxy, and the X-Men. Despite their best efforts, these heroes have often struggled to defeat Thanos, making him one of the most formidable and dangerous villains in the Marvel Universe.

Quicksilver, also known as Pietro Maximoff, is a Marvel Comics superhero who possesses the ability to move at superhuman speeds. He was created by Stan Lee and Jack Kirby and first appeared in X-Men #4 in 1964. Quicksilver's powers are a result of his mutated physiology, which allows him to move at incredible speeds, run across water and up walls, and even create afterimages of himself. His reflexes and reaction times are also enhanced, making him incredibly difficult to hit in combat. In addition to his speed, Quicksilver is also a skilled hand-to-hand combatant, having been trained by his father, Magneto, in martial arts and strategy. Quicksilver's history in the Marvel Universe is complex and has evolved over time. He and his twin sister, Scarlet Witch, were initially introduced as members of the Brotherhood of Evil Mutants, led by their father Magneto. However, they later defected and joined the Avengers, where they became important members of the team. Quicksilver has also had numerous solo adventures, where he has faced off against some of the most dangerous villains in the Marvel Universe. His speed and agility have allowed him to take on opponents much stronger than himself, and his tactical intelligence has allowed him to outmaneuver even the most cunning of foes. In addition to his comic book appearances, Quicksilver has also appeared in multiple adaptations in other media, including the X-Men and Avengers films. He remains a beloved and iconic character in the Marvel Universe, known for his lightning-fast speed and unwavering determination.
