Hyperknight

The Hyperknight is the third Zard to appear as an enemy in Black Citadel. They enter the battlefield on a Hyperbike, boosting their movement speed by a lot, enabling them to reach your base in 6 seconds or more. Upon hitting a building, they will crash and deal damage equivalent to the remaining HP of the Hyperbike, while dismounting into a "second life," boasting big damage.

A Robo Bully is needed if not required for Hyperbikes, as if left alone, they deal 200 damage! Robo Bully's Shield Absorb was actually nerfed due to Hyperbike HP being nerfed from 300 to 200.

After dismounting (in a cool way), they use an ax to hack your defenses and you into pieces. Their movement speed is also significantly lower after dismounting, in which case they become far easier to deal with. Towers that do great against Hyperknights are: BETTY, Bunker, Scorpio, Viper, Tesla Tower, Alchemist Tower, and Cannon.
