Developer

The Developer is a misterious unconfirmed tank in Diep.io. Some people say it's a joke, some say it's the developer trolling people, and others say it's the Illuminati.

First Report - August 28th
The first report of this tank was in August 28th, when it misteriosly appeared in a server with few people. They say he was a huge tank with a gold name "Developer" above it. They said it was a machine gunner, then became a sprayer, then a Stalker, then disappeared.

Second Report - August 29th
This day, the developer of Diep.io says that he accidentally let out developer cheats not password-protected in the game. But even after this, huge yellow-named tanks named "Developer"s were still appearing. People think it's the Illuminati or maybe just the developers.

Thrird Report - September 4th
Right when Sandbox mode launched, people said to be finding unknown invisible entities with apparently infinite health, and when ram into it, it says "You were killed by Developer".
