— Giant Zavok, Sonic Lost World

Giant Zavok[2] is a transformation that appears in the Sonic the Hedgehog series. It is a form of Zavok achieved through a secret formula during the Lost Hex incident.[1]


As the name implies, Giant Zavok simply resembles a much larger version of Zavok, with his spiked bracelets enlarged accordingly.


Sonic Lost World

In Sonic Lost World, after being defeated by Sonic in Lava Mountain, Zavok jumped down from their battle platform and transformed into Giant Zavok in a last-ditch effort to defeat the hedgehog. As he chased Sonic up through the large shaft of the base, however, Sonic used the loose terrain to his advantage and managed to knock Giant Zavok down the shaft, defeating him for good, and presumably reverting him back to his base form.

Powers and abilities

Like in his base form, giant Zavok is incredibly strong and resilient, except to a much greater degree. Additionally, he can fire deadly beams and large fireballs from his mouth, both of which pack destructive power.


Giant Zavok is the final boss of Lava Mountain Zone 3, and the preultimate boss of the Wii U version and PC version of Sonic Lost World. He is fought at the end of Lava Mountain Zone 3 with Sonic the Hedgehog.

Boss guide

The boss fight begins immediately after the previous one, as Zavok will jump into the pit below the battlefield and grow to a giant size off-screen. From there, Zavok then slowly begins to climb up, destroying platform blocks as he goes. If the player falls into the pit where Zavok climbs it will cause the player to lose a life, so the player has to climb to higher platforms to keep ahead of him. While Zavok is climbing, he will also take pop-shots at Sonic by shooting fireballs and sweeping lasers from his mouth. The fireballs will destroy any platform it hits, and the sweeping laser will only destroy thin platforms, but sweeps across the entire course.

To damage Zavok at this point, the player has to use the Bound Jump to knock the explosive crates, which are suspended amongst the platforms that the player uses to climb, down at Zavok to damage him. The player can get in quite a few shots quickly by using the row of crates Zavok was using previously to deal a good chunk of damage, but barring that the player will have note his/hers surroundings when going for others which will block the player's shots. Zavok's fireballs can take care of that problem easily, though. After hitting Zavok with enough explosive crates, he will be defeated.
