Gyro Ball

 is a Tier 5 Tank that upgrades from Jump Smasher and Iron at level 60.

Design
The is simply a combination of Iron and Jump Smasher. It looks very similar to Jump Smasher, retaining its signature octagonal shell, but its color is changed to match Iron's unique shell.

Trivia

 * This tank is named after the Pokemon move of the same name.
 * If this is the case, it would be the second Iron branch named after the Pokemon franchise, the first being the Steelix.
 * Alternatively, its name could also be a reference to JoJo's Bizarre Adventure where Steel Balls are weapons used by the character Gyro Zeppeli.
