Quick Answers

Who are the Brain Boyz in the context of the Orks? toggle section
The Orks refer to their ancient creators as the Brain Boyz, possibly the Old Ones. These creators engineered the Krork, a warrior race and potential ancestors of the Orks. The Brain Boyz imbued the Orks with technological knowledge and psychic abilities at a genetic level. However, they disappeared or became extinct during the War in Heaven.

What is the connection between the Brain Boyz and the Krork? toggle section
The Brain Boyz, identified by Orks as their ancient creators, are thought to be the Old Ones. They created the Krork, a warrior species, during the War in Heaven, millions of years ago.

How did the Brain Boyz influence the creation of the Orks? toggle section
The Brain Boyz, potentially identified as the Old Ones, played a crucial role in the creation of the Orks more than 60 million years ago. They imbued the Orks with scientific knowledge and gestalt psychic abilities at a genetic level. The Brain Boyz also fashioned the Orks as a warrior caste, co-existing with the Aeldari's ancestors, and crafted the Krork, a warrior race that may be the Orks' progenitors.

Were the Brain Boyz the same as the Old Ones in Warhammer 40k? toggle section
The Brain Boyz, known as the Orks' ancient creators, are theorized to be identical to the Old Ones, a vanished xenos species. They are believed to have engineered the Orks as warriors during the War in Heaven, akin to the Old Ones' creation of the Krork. However, this connection has been downplayed in recent Warhammer and Warhammer 40,000 editions to differentiate the two universes more distinctly.

History[]

During the War in Heaven millions of standard years ago, the Old Ones created a warrior race known as the Krork, from which the present-day species of Orks may derive. It is believed that the Brain Boyz engineered the Orks to be their warrior caste alongside the ancestors of the Aeldari, using them as essentially humanoid biological weapons to protect them against various other ancient races.

In the Old Ones' case, the Krork were created as part of a desperate ploy to defeat their ancient enemies, the Necrons and their C'tan masters, during the galaxy-spanning conflict known in Aeldari Mythology as the "War in Heaven" over 60 million standard years ago.

The Brain Boyz are believed to have encoded various forms of technological and scientific information into the genetic structure of the Orks at a cellular level, as well as provided the Greenskins with their unusual gestalt psychic abilities that grow stronger as the number of Orks in a given locale increases.

Therefore, an Ork engineered to be a Mekboy is born with an understanding of the basic principles of physics, along with "Orky know-wots" that allow him to maintain a relatively high level of technology for such a barbaric and uncivilised species. Almost all Orks are born with the knowledge of how to hammer bits of scrap metal together and create and operate basic Ork weapons of war, while the Mekboyz intrinsically understand how to assemble a Killa Kan, or a Battlewagon.

Likewise, Ork Painboyz are born with a simple understanding of Orkoid anatomy and physiology that allows them to tend to the injuries of their fellow Greenskins with very painful and often very unnecessary surgeries.
