Adamantium Overflow

[Synch]

And I'm sure I don't need to mention that something being unbreakable can change hell of a lot more in a story than a shipful of gold.).

Well, first of all, it depends on the size of the ship.

An overflow of adamantium cheapens the character Wolverine, just like Superboy, Superdog, Supergirl, Supercousin and Beppo the flying Supermonkey cheapens Superman (although, I confess, to a lesser degree).

That's a good point. I didn't even know there was a super monkey.
