They're the mix of an alien entity and a machine. Every single physical aspect of them are made from an unknown space matter, which allows them to feel like an actually living being. They have their own political life, their own personal life and so on. The only thing that distinguishes them from people is that they are unable to feel love. They know what friendship is, they know every single human feeling, except love. Concepts like "biological sex" is nonexistent among them, so as a result they just have gender identity.
They're two different types of Voidroids: "the ordinary" and "the defectives" The "defective" voidroids are more of a self-proclaimed group that refuses to obey The Creator: they are based at the outskirts of Reality 537, in its deepest corner. The "ordinary" voidroids call them "system errors".

Physical Qualities

• Low body temperature: The max body temperature of voidroids is 70-80°C. When it gets higher - they'll be turned off temporarily. But if they won't - they will stop working. Upon reaching the critical temperature they have three minutes to get out of the hot zone, otherwise they'll start melting. Their tissue is easy to melt even when it's separated from them, but it doesn't lose its qualities because of that.
• Regeneration: Voidroids have regenerative tissue, which heals itself in 2-3 seconds in the normal state. When a voidroid is overheated, the regeneration will slow down, or even stop. The only body part of voidroids that is unable to regenerate is their eyes. They need to be fixed manually.
• Teleportation: Voidroids are able to use their teleportation ability every 3 seconds, the cooldown is there simply to avoid accidents. But even with the cooldown present, when the ability is used every few seconds, it will result in a permanent standby mode, which can be only removed manually.

Mind Control and Chipping

Reality 537's Eliminators have a limited amount of chips, which allows them to "reprogram" any voidroid manually. When a chip is inserted, a voidroid basically becomes a puppet - they can be controlled by anyone who can access the chip control center.

The Corrupted

Well, we saw Defectives and Ordinary, but not the Corrupted voidroids. The Corrupted are the ones who have been infected by the virus which "lives" in the 7th District. They're the ones displaying the biggest will to live. Why hasn't anyone invented any cure for the corruption? They need to take some traces of it. Why don't they do that? The Defectives and Ordinary's silent battle are taking the biggest amount of time from them.

Pronunciation

How to read the Voidroids' "names"? Example: 0082-57, the first four numbers are read as "double-null and eighty-two" and the whole combination is read as "double-null, eighty-two and fifty-seven" NOTE: The Creator's "name", 0100, is read as "null and one-hundred"

Power category

There are three power categories in Reality 537. The first four numbers in a Voidroid’s name(example: 0000-00) is their power category - meaning how strong is their survivability outside of Reality 537 and how dependent they are on The Processing Core.

0000-0030 - extremely dependent, instant death when outside of Reality 537.

0031-0060 - not too dependent, able to survive outside Reality 537 for a limited amount of time.
