I read a thread somewhere that said Zwei's semblance is the ability to adapt his body to his needs - he fits into the postage tube, and he coats himself in the flames of Oobleck's weapon and hardens his skin to become a flaming cannonball. Similar but not quite the same, which is probably the case with most semblances - unique but you can group people together for the similarities they have.
