¿Who is stronger, Captain America or Shang-Chi?

Captain America is one of Marvel's most iconic heroes. Created by Joe Simon and Jack Kirby in 1941, Captain America made his first appearance in Captain America Comics #1, just before the United States entered World War II. Since then, he has become a symbol of patriotism and justice in the Marvel Universe. Captain America is the alter ego of Steve Rogers, a frail young man who volunteered for a secret experiment that turned him into the ultimate super soldier. As a result, he has superhuman strength, endurance and agility, as well as exceptional leadership skills. With his indestructible shield, Captain America is a formidable fighter on the battlefield. Over the years, Captain America has battled many dangerous villains, including the evil Red Skull and the terrorist organisation Hydra. He has also led the Avengers on several occasions, becoming one of the most important members of the team.

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.
