Overlord

The Overlord is a Tier 4 tank that upgrades from the Overseer at level 45.

Design
The Overlord has a circular body with 4 trapezoidal drone spawners. It is quite recognizable and is a symbol of Diep.io.

Technical
Like the Overseer, it can have 8 drones. However, the Overlord can get these 8 drones faster than Overseer can. It also gains a bit of FOV.

Upgrades
The Overlord upgrades from the Overseer. It can upgrade into the following:
 * Overworker
 * Professor
 * Juggernaut
 * Overlooker
 * Microbe
 * Guerilla
 * Carthographer
 * Mothership
 * Hoinfodaman
 * Dr. Tide Pods
 * Overmaster
 * Overluxe
 * Lord Trapper.

As the Overlord

 * You can now stand a chance against these snipers and bullet spammers just because you replenish you drones very quickly.
 * Ambush AI tanks with your drones instantly because you have increased FOV.
 * Your drones are now quite powerful. Chances are you will have several drones left after killing someone.

Against the Overlord

 * Don't attack the Overlord unless you have serious range (Assassin or better), you have wide coverage (Penta-shot), or if you are a really good player.
 * Underseer-branch tanks are really good if you have good drone speed.
