In the 1990s X-Men animated series, there is a two-part story called "Savage Land, Strange Heart." In this land, Sauron has a dampening field that nullifies mutant powers for those who don't have a special device.
When the team of X-Men arrives, their enemies say it is pointless to fight because they don't have their powers. Wolverine pulls out his adamantium claws and says, "There's nothing mutant about these."
Since Wolverine retained the artificially implanted adamanium, shouldn't he have died in the Savage Land? He didn't have his healing factor, so how did his body extract the blood from his encased bone marrow?
Even if he didn't immediately die, he should have been poisoned by heavy metal toxicity. Also, without the superhuman strength granted by his mutant powers, he should have been unable to move, or at least severely encumbered, due to the sheer weight of the adamantium.
