1) It's "Absorbing Man" logic. He calls it Inorganic Absorption too, despite being able to absorb wood and leather and stuff. It's the fancy way of saying "Anything not alive." I'm not sure what else to call it, frankly.
2) Sorry about the history things. I figured out the broad strokes of the story and tried to vibe with that, but couldn't find the details, so I left things a little vague to try and not step on anyone's toes. This also includes the Thor thing.
3) To be fair, I did put the age that he was brought to the mansion "when he was 12 years old that his Mutant Powers activated. After his father attacked him he went on the run, eventually being found by Charles and the X-Men after a month surviving by himself" as well as when he graduated "He has a brown leather jacket with "Xavier Institute Class of 2004"" that being said, I did just notice the discrepancy saying that he studied for 7 years when it would have been 8 by 2004. My bad, I will change that.
4) I'd like to keep the Weapon X thing for his crippling, if that's possible. Specifically because it goes to show his state of mind in how he operated when he was young. The kind of guy to to throw himself on Adamantium claws in order to strip said Adamantium and give the others a chance to fight the creature. The other reason is because it plays into his character for the whole "Maybe if I hadn't been so reckless, I could have aimed right and missed my spine." That being said, if the Weapon X thing contravenes a few bits of established Lore, I'll change it.

Apart from that, I'll make some changes when I can, adding ages to events and changing some things around.
