This is how I think the letters will spell words with Z. In my AL universe, Z has a volcano on him called the Zolcano, which shoots Z-shaped lava that solidify into rock, called mini Z's. They look just like Z, but darker and a normal-pitched voice. The mini Z's also have durability, as they break after 5 usages of them in words.
