I don't now know what would be the correct answer here.
But I believe that assuming her petrification gaze can work through a camera isn't acceptable without any evidence. So I'll debate with this in mind.
Medusa's Poison is also pretty useless, since she has to beat the Hulkbuster to get to the pilot. And the Combat Warden is very agile, more so than I've seen of her.
They can make quick rapid turns, enhances their strikes with electricity, fire homing missiles which can annoy, and restrain her easily with their Lifting Strength advantage.
He's more mobile with flight and has ranged attacks to rely on, such as missiles and
electric blast.
Medusa is stronger, but not by a large amount. Especially since the Combat Warden should upscale from 577 Tons by a good amount. Due to Hulk's direct attacks would be stronger than the shockwave they created, and that the military believed these Hulkbusters would defeat him.
Honestly I'm thinking the Combat Warden can take her, unless someone is some absurd god of skill. Hulk may be stupid, but he's a clever fighter. Also Hulkbusters move in real time in response to the pilot, which means they're at least on the level of a highly trained military soldier.
