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.

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.

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.
