¿Who is stronger, Quicksilver or Shang-Chi?

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.

Shang-Chi, also known as the "Master of Kung Fu," is a fictional superhero in the Marvel Comics universe. He made his first appearance in Special Marvel Edition #15 in December 1973 and was created by Steve Englehart and Jim Starlin. Shang-Chi is considered to be one of the greatest martial artists in the Marvel Universe, with incredible agility, reflexes, and strength. Shang-Chi's history begins with his father, the infamous criminal mastermind Fu Manchu. Shang-Chi was raised and trained by his father in the ways of martial arts and was initially sent on missions to carry out his father's bidding. However, when Shang-Chi discovered the true nature of his father's activities, he turned against him and joined forces with the British intelligence agency MI6. In the comics, Shang-Chi is often portrayed as a loner and a master of several styles of martial arts. He has demonstrated incredible speed, agility, and strength, which are all enhanced by his mastery of chi energy. Shang-Chi has also trained his body to resist injury and possesses an exceptional healing factor that allows him to recover from wounds more quickly than a normal human. One of Shang-Chi's most notable abilities is his "One Touch of Death," which allows him to strike a single, precise blow that can kill or render an opponent unconscious. Shang-Chi has also mastered the use of weapons, particularly the nunchaku and the staff. Shang-Chi has faced many formidable foes in his adventures, including the likes of the Mandarin, the Yellow Claw, and the Iron Fist. He has also been a member of several superhero teams, including the Avengers and the Heroes for Hire. Overall, Shang-Chi is a skilled and powerful fighter with incredible physical abilities and a mastery of martial arts. His strength, speed, and agility make him a formidable opponent, and his skills have earned him a place among the greatest fighters in the Marvel Universe.
