Volttzos are enemies in Kirby's Return to Dream Land. They are giant, green, cylindrical cannons. They appear to be a sub-species of Shotzos (who also appear in the game), along with Coldtzo and Gigatzo. Out of all other three cannon cousins, Volttzos appear to be the most mechanical-looking. Volttzos mostly appear in Egg Engines, however, some can be encountered in Nutty Noon. Volttzos attack by constantly firing giant balls of electricity that travel in the direction fired in. These projectiles cannot be destroyed or Inhaled, so they must be avoided at all costs, otherwise any hero (Kirby, Meta Knight, King Dedede, Bandana Waddle Dee) that touches one will take damage. Much like with Shotzos, Gigatzos and Coldtzos, these enemies cannot be defeated unless dropped into a pit. Some Volttzos, however, can be encounted in the background of the stage, so therefore, they are invincible to all attacks. Much like with its cousins, Volttzos cannot be Inhaled. Volttzos appear in the Item challenge of the game. It is to note that Volttzo's name is a combination of the word "volt" and "Shotzo".
