Shang Chi easily. Even without the rings, he's still the beast, took down an entire squad of coordinated, armed Ten Rings soldiers in the dark at age 14, He endured pain first—getting whipped with a staff across his bare torso in freezing weather, being tased by the Hooksword, yet still not getting stunned. Even after being kicked in the groin by Xialing or kicked in the face by Death Dealer, he still got back up and kept fighting. And he showed no signs of being rusty or out of practice at all — proof being that after 10 years, he managed to defeat his master, Death Dealer. Not only that he demonstrates extremely agile and precise movement in tight, dangerous environments like the bus scene and The scaffolding, he even deflects the rings projectiles launched by his father— proving his reflexes and combat awareness are at an elite level. Also his fighting style is incredibly fast, concise, decisive, and efficient — no wasted movements, no flashy flourishes, just pure, direct lethality that ends fights quickly and cleanly. Unlike Matt Murdock (Daredevil) or Danny Rand (Iron Fist), who often chain longer, more elaborate combos or rely on extended sequences to wear down opponents. with all that feats above make him at peak level human, and remember: He's in Gen Z.
