for Korra, lets assume she'll go with this
Korra was poisoned during the feat in question and Kuvira has better reactions with this. Kuvira is also an opponent familiar with bending and the concept of the Avatar, whereas Cap doesn't know what he's up against. An opponent unfamiliar with Korra and in an enclosed setting will not dodge as easily.
So in half a second Korra is going to be able to throw 5 attacks out at Cap. Assuming they're firebending attacks
Even with this lowball estimate Korra has several attacks with stopping power available to her, especially if she doesn't arbitrarily forget she can bend other elements. She can earthbend or airbend underneath her opponent well within that time. Even if his costume is fireproof (which apparently means he can stand around fire) it's clear Korra's fire attacks have concussive force and a directed fire attack can burn hotter than standing around fire.
Korra almost certainly can't bend Cap's shield
Platinum is the only metal she can't bend. Vibranium is a meteorite and earthbending works on meteorites. It was literally the first metal Korra bent, and it's what she's bending in battle here. I'm making no claims she can affect the shield's integrity, but she can move it.
Korra doesn't have the feats to redirect it with air judging by how hard Cap is chucking it
It's not in character for Cap to throw a tank-busting attack at a girl he just met. Korra's redirection is against stone-piercing projectiles that aren't literally shaped like a frisbee.
The big aoe is manageable considering it's just fire, and Korra has to do motions to accompany all of her attacks, so they won't be a complete surprise, especially considering Cap's skill.
As I've already said: her fire has concussive force, Cap is unfamiliar with bending, the AOE can encompass the hallway, and the AOE includes attacks that come from every possible direction.
She isn't going to get the kind of amp you're showing here from literal foot deep water.
Maybe she wouldn't be able to use the water spout, but given the surface area of the water she has plenty for her freezing attacks.
There's no way this is standard gear, she doesn't have this glider. Even if she did, it occupies both of her hands, so its not like she could use the advantage meaningfully.
She's used the glider well over the tourney-minimum of twice, she can bend with the glider, hold it in one hand, and can bend with her legs just as easily as arms.
Both of these attacks have extremely noticeable wind-ups, Cap is super unlikely to just stand there and let her do this.
My opponent keeps assuming all Korra is capable of is small straightforward blasts when I've demonstrated far more variety from Korra than that. I fail to see how this, for instance, has some predictable windup.
I seriously doubt any of her attacks are strong enough to pull this off
Unless Cap weighs an absurd amount Korra is plenty capable of lifting him.
Cap is of course, famous for being incapable of breaking out of ice
It's kind of weird that you didn't include the surrounding pages where Cap was frozen for so long everyone thought he died and then he was intentionally awoken by those holding him by raising the temperature of the ice.
He literally didn't see this arrow, obviously he didn't react to it.
He didn't see this arrow after dodging two previous projectiles? Did shuriken and a billy club fly by and he just thought "Huh, that's weird. Ow! An arrow!" Here is another arrow nailing him from right in front of him. Here's him getting hit with some bullets. Cap exchanges blows with non-bullet timers all the time, this idea that because he's dodged bullets before means he automatically dodges anything slower than a bullet (even with huge AOEs from all directions) is absurd.
this escape mechanism relies on a non instant technique, so it's likely useless, also Korra is unlikely to use a technique to run away at the start of the battle
Her air scooter is faster than turning the key to the motorcycle's ignition. The window is practically right next to her, and she's not running away so much as strategically positioning herself.
Korra is downed and heavily injured by a blast
I mentioned this was while she was poisoned, but is bending a pole really more impressive than shattering stone? Or this where her body crumples metal rather than denting it?
Conclusion: Korra's massive ranged advantage still stands along with her win conditions, and ability to withstand and escape a melee.
