Zor is the fifth boss of the Nintendo 3DS version of Sonic Lost World, serving as the recurring boss of Silent Forest.
In the Nintendo 3DS version, Zor is encountered at the end of Silent Forest where he stands atop an owl mech and prepares to charge a deadly laser at Sonic. The player must climb into a cannon and use the Nintendo 3DS gyroscope to aim at Zor and shoot him down. They must be careful, as there are numerous fake owl mechs that, while not harmful, will waste the player's time and give Zor a chance to finish charging his laser. Despite being obscured a bit by shadows, the fake owl mechs tend to be quite different from that of the real owl mech, allowing the player to distinguish the real owl mech amongst them.
Once Zor is hit, he will be grounded, allowing the player to beat on him with Homing Attacks. After a while, he will get back up and repeat his attack until he is defeated. When aiming the cannon, the player can fire Sonic at capsules containing Gray Wisps, allowing the player to use Gray Quake on Zor for critical damage.
This battle is repeated in Lava Mountain Zone 2, following the battle with Zeena. In this rematch, Zor has more health and his attacks are harder to avoid.
