White Mustache

Overview
White Mustache is currently the strongest boss in the game. He's special, requiring the user to open the door in the Prison Island with a Mysterious Key, having an 1 hour cooldown to be fought again. Its appearence is similar to White Beard, although there are noticeable size differences. White Mustache can drop the Bisento, the strongest Weapon yet, with a 10% chance. Its level is 1.500, thus the highest out of all bosses.

Tips

 * It is recommended to keep your distance, and only use close-ranged attacks with a fully restored health pool, since he can be very dangerous.
 * Avoid the use of Pika Pika no Mi. Some of its attack can cause lag, which will make it so other fruit's effects stay longer, thus making it harder to see.
