MCU Iron Man vs MCU Fenris
There is no MCU Fenris, do you mean the von Strucker twins from X-men: The Gifted?
Yeah, there is a Fenris. He was in the last Thor movie.

"But... But I want to be a big karate cyborg... ;_;" - Nik Hasta
"Get off my lawn! ...on this forum, that just makes people think of Cyclops." - Sharpandpointies
"...makes me think the Night King just says "Screw the rules, I have magic money" when it comes to physics." -Captain Morgan
The dog could just eat tank Missile, did not seem that impressive durability wise.
Well Fenris did tank getting shot by the gatling gun Thor gave to Valkyrie from the Asgardian armory

The same gun did some damage to the Bifrost

She also got punched by Hulk hard enough to flip over, and smashed right through the side of the bifrost

Lightning cloak Thor driving his sword into the Bifrost did just minor damage

He had to do a sustained bolt of lightning to break a portion of the bridge

Grandmaster's ship crashing into it did zero damage

Hulk being thrown onto the bridge by Surtur didn't do as much damage

Of course, there is the first time where it was destroyed too in Thor

And the Dark Elf ship falling onto it with zero damage in Dark World

While not as impressive as above, there is getting dragged back by Hulk via the tail and smashed through atleast one of the stone structures

She got punched and suplexed by Hulk

There is also getting punched hard enough to lose the grip on Hulk and flip over

I also think this should be considered a durability feat for her, since Hulk stopped her momentum cold. It should have shattered her jaw, but didn't

Also, considering her size, would a tank missile do.significant damage? Not to.mention, only 3 of MCU Iron Man's armors have missiles that kindpower - Mk3, Mk7 and Mk 50. Others all have RPG level missiles
