Hold on, isn't resistance towards intangible attacks on his last key anyways?
I think he's refering to energy orbs Samus gets by killing normal enemies, not the bits of Aeion.
Back to your post against mine:
I don't have scans on me, so I'm literally gonna have to get random fight scenes from his fights and mention a few notable ones:
The original fight that damaged his Mark 45 (This armor) and by extension most of his fights as part of the GotG (Not sure about the exact number), his fight with Captain Marvel in Civil War 2,
this random one,
another one, his fight with the Superior Iron Man (Both the AI and him didn't use Absorption much if at all), the fight with Rescue, literally everytime he's fought the Hulk (including "Hulkling" foes like in Superior Iron Man, ie Original Sin, World War Hulk, Crash and Burn), my knowledge of Marvel comics really only perminates with Spiderman (Well I skipped a few of Dan Slott's run) so I can't really comment much more, but those are just some notable ones. Give me a while and I can comment more.
To be honest, I agree with Iron legion (Mostly because the number of times he's overwhelmed on Earth is much smaller). Issue is I'm not sure they would arrive in time, and some of the earlier incarnations can be easily hacked by Samus.
As for Iron Man's fighting style, generally repulsor rays (earlier incarnations use h2h more often didn't they?). Of course my understanding with Iron Man is mostly thru the bigger events and when he's in a Spiderman comic, so I'm probably wrong. But six times he's used Absorption? With a character whose spanned decades amoung multiple runs and teams? You would need a lot more to even remotely imply that Absorption is the case.
He does different things with preperation and previous experience of course, but that's not the case here. Btw, grace stopped the moment more people started voting for Samus.
