Zavok is the sixth boss of the Nintendo 3DS version of Sonic Lost World, serving as the recurring boss of Sky Road.
Zavok is encountered at the end of Sky Road like the Wii U/PC version, only his battle is a skydiving battle, as Sonic falls in the sky to defeat him. Unlike other bosses, regular Homing Attacks are ineffective, so the Homing Attack must be fully charged to do any damage to him. After the attack hits, Zavok will be stunned, giving the player enough time to charge up another Homing Attack to the max to deal more damage. Alternatively, Cyan Wisps appear, allowing the player to use Cyan Laser against Zavok to deal more damage than normal.
Like his Wii U/PC battles, Zavok rides a mechanical dragon, only here he will try to ram the dragon into Sonic to hurt him. After enough damage is dealt to Zavok, the dragon will start shooting fireballs and lasers to attack Sonic, even encircling Zavok to fire four lasers which Sonic must avoid. By holding down the button and using the Circle Pad to move Sonic, this attack becomes easier to avoid. After the attack, Zavok will be stunned, making him vulnerable to attack. The battle ends once Zavok's health bar is fully depleted.
This battle is repeated in Lava Mountain Zone 3, following the battle with Master Zik. In this rematch, Zavok has more health and his attacks are harder to avoid.
