Matthew Hagen was a treasure hunter, seeking antiquities on land and below sea level that could propel him into fame and fortune. During one of his dives, he came upon a cavern that defied explanation. There was no treasure to be found there. Instead, he found himself trapped in a type of clay that ultimately transformed him into something like the multicolored clay itself.

Hagen found that this pool of protoplasm he had stumbled into gave him the ability to change himself into any shape he could conceive. He could duplicate the color, texture, and abilities of the form he chose. Hagen knows knowing of hand-to-hand combat, and he is beyond the need to know such things.

But for all that he might have become, now that he could become anything, he could not quiet his restlessness, his need to be more than he was. Yet he has never become more than a petty criminal.
