Bee Server

Bee Server (ビーサーバー) is the sub-boss of Hellbat Schilt's stage in Mega Man Zero 3. It is a giant robotic beehive that appears in a weapons factory where the Resistance sent Zero to investigate.

Strategy
It releases Mellnets and shoots out globs that resemble honey. The globs slow Zero down, making it easier for the Mellnets to hit him, and also makes it harder to climb walls. It's only vulnerable when it's open. Hitting it with a charged Recoil Rod attack will cause it to shake and send out a Mellnet. When it's defeated, it'll drop a Secret Disk with the Cyber-elf Anater.

Alongside the weaknesses listed, Saber Smash and the Z-Saber (while charged) is also effective at defeating it.
