Arbiter-X

 is the eleventh zombie encountered in Sky City in the Chinese version of Plants vs. Zombies 2. He makes zombies from all columns behind him transparent, making them unable to be seen by plants but can still be hit, just not targeted. Additionally, like many other zombies in Sky City, he will destroy any plant upon contact with it.

Strategies
This is much like the Glitter Zombie, aside that it has much more health, does not require a jam to use its ability, and also protects all zombies in all lanes behind it from plants' sight. A Ground Cherry will enable the hidden zombies to be visible to plants so they can attack it, but slots are too valuable for this usage and there are no area-of-effect aerial plants, so it would not help much. Additionally, the Arbiter-X does not hide itself and can still be attacked when its force field is intact. Any aerial plant that runs into it will be killed and if it reaches the edge of your castle, it will ram onto it, die and do massive damage to the castle. Winter Melons can slow it down along with the other zombies made invisible, and other high-firepower plants can destroy it easily due to its slower speed than a Double-Cabin Aircraft Zombie. Saucer can be used, as it will stop the Arbiter-X from moving temporarily, allowing the other zombies behind to go across it, eventually making them vulnerable to the other plants' attacks.

Air Raid
An Arbiter-X will appear as the final boss of the Air Raid Brain Buster, and will be first accompanied by Flying Buckethead and Conehead Zombies. Destroy them as fast as possible as they will make the fight more dangerous. While it seems easy at first, After it reaches half HP or less, it will start to throw bullet patterns that have narrower leeways than your plane and will be virtually impossible if the player is low in health. If the player does not defeat it as fast as possible, it will cause the player to spend countless gems on continues.
