Fallen Hybrid has a gray circle base with a Destroyer cannon in front and drone spawner in the back.
Fallen Hybrid is similar to normal Hybrid, but far stronger. It has one drone less than Fallen Cavalcade, but they are more powerful. Drones have same speed, but higher health and damage, but in return lower reload.
Fallen Hybrid shoots strong annihilator bullets, which can kill most tanks from one hit. Bullets have high penetration and health, as well as speed higher than Hybrids.
Currently does not spawn.
The main ammunition of Fallen Hybrid, bullets, have medium speed and somewhat long reload, so your mobility and bullet speed is key. You can trick Fallen Hybrid is missing by moving in a left-right pattern, and it will most likely miss a bullet. Bullets and minions can deal with this boss effectively.
Drones of Fallen Hybrid are a problem since they deal decent damage. As a bullet tank, try to eliminate drones first as they are pretty strong, but can be killed fast if you focus all your firepower on them. It is trickier to do with minions but still easy - you have to keep all minions between you and Fallen Hybrid, and then when drones charge in you ram your minions into the drones.
Fighting in groups will demolish Fallen Hybrid even faster: it will focus drones on one player and bullets on another. While it will do low damage to both players, it will take heavy crossfire and a lot of damage, and thus will fall very fast.
