It has a brown square base with 3 grey auto turrets, one on the top and 2 on the sides. On its back are 4 blue Crasher spawners. There is a large grey Stalker-like cannon on its front.
The Tank-killer is quite simple. It just shoots people with its cannons and spawns Crashers. It also only attacks tanks over or at level 30 unless provoked. It only has 2 abilities, in which only 1 can be used more than 1 time.
EXTERMINATE: Kills everyone in the server when it spawns. Only used once.
Rise!: Pumps out anywhere from 1 to 100 Crashers, then shoots at them with its main cannon. Crashers hit will be converted to Guardians.
The Tank-killer gives 30000 XP on death like any other Diep.io boss. Crashers and Guardians will not attack the player who killed it, nor will the player be able to attack them.
- Obvious reference is obvious. (The name, colour scheme and spawn ability)
