Well see I was thinking about how JTG said the satellite only handled unnatural mutations and then I thought about how Iron Man got an "unnatural" mutation from that virus. I'm referring to his intelligence/ability to think. This issue did explain that it is above average due to an outside force. Even if he's not as smart as Reed Richards, he's still smarter than he was meant to be, naturally. So I thought why didn't the satellite take him out? Then I realized that he was still an unborn child... (sorry I don't know the exact terminology to pregnancies. Is it Fetus?) but anyway that means the mutation was natural to him and that make him a mutant.
