Shang-Chi vs Spider-man:
Okay, I'm going to assume this is Shang-Chi without the rings or any Ta-Lo gear, and Spider-man with his "normal" Starktech suit, since that is what is shown in the pictures. Given that? Spider-man should win. Shang-Chi is good, real good. He's good enough I'd say he is the best martial artist in the MCU ( outside of other characters in his own story ), and good enough to actually be in the same weight class as super soldier types ( if at the lower end compared to someone like Steve Rogers ). That just isn't good enough against Spider-man, sadly, mainly because Peter has too many ranged attack options, and Shang-Chi just doesn't have many good counters to webbing. He can't catch it, he can't parry it, its hard to dodge it if its an area webbing attack, and he's not strong enough to just break it. 10/10 for Spidey, Shang-Chi just doesn't have the right tools for this match.
Martial arts skills, no matter how amazing, do not make a person superhuman - although this is a common conceit in Kung fu films.
Remember how Karli, a relatively unskilled super soldier killed a highly trained spec ops soldier with a single punch?
Shang Chi might be able to avoid dying right away, but against any super soldier he's dead meat eventually. John Walker would break him in half, Cap or Bucky are going to crush him easily.
Spider Man is physically stronger than super soldiers, if he hits Shang chi once, its fight over - the tech suit is just overkill.
If you dropped them both naked in a boxing ring, it'd be a *little* better for Shang-Chi, but not great. Peter is a bit of a glass cannon as people in his weight class go, but while he's less skilled than Shang-Chi he's also superhumanly enhanced in agility and reflexes, the same area that Shang would otherwise be using as his own advantage. 8-9/10 to Spidey, with Shang-Chi winning a couple because he landed *all* his dodges and parries until Peter was worn down.
I am disappointed in you- as a guy who generally makes logical points based on observed feats. My friend you are demonstrably wrong about the "glass cannon" here
Look at Peter's durability feats:
- Peter survives being hit by a TGV train, at speed, with minimal injuries. If Shang Chi had a similar experience, he'd be reduced to paste.
Spider Man can feel pain but he takes full on kicks from Captain America and doesn't die or get KO'd.
The impact of Giant Man's arm hitting him and knocking him into a pile of crates would have easily killed a human being.
Shang Chi might have wonderfully flashy punches and kicks but they aren't going to do anything to Spidey.
If you spotted Shang-Chi some Ta-Lo gear, *then* it becomes more competitive. A dragon staff gives him both a means to much more quickly hurt Spidey if he lands an attack, and a means to plausibly parry and cut webbing. I'd still say Spidey wins 6/10, but its a lot closer.
And naturally, if you give Shang-Chi the Ten Rings, well, he's basically going to win all the time, due to now being an entire power tier *above* where Spider-man lives.
The Ten Rings I can only describe as having magical plot bull**** powers - they are a plot device that allow the writers to do whatever they need them to do to make the plot happen.
I might point out that Shang Chi's mom beat his dad ( with the ten rings) and if she's only human than Spidey is a lot faster, stronger and tougher than she is, victory for Shang is not a foregone conclusion at all.
So, in summary, I disagree.
