The Jokaero are an intelligent, psychically-powerful alien race who resemble the orange-furred great apes of Old Earth known as orangutans. They were created by the Old Ones during their war with the C'tan over 60 million Terran years ago for the purpose of aiding in their conflict with the Necrons, along with many other intelligent races of the Milky Way Galaxy such as the Eldar and the Krork, the ancestors of the Orks. The Jokaero's defining racial trait is their extraordinary and seemingly in-born skill at crafting extremely advanced technologies from even the most rudimentary parts, a skill which may be related to the similar trait often seen in the Orks. The difference is that Jokaero technology will work for a member of another species, whereas Greenskin technology often will only function when used by Orks.
Recently, Inquisitors, most commonly the more Radical members of the Ordo Xenos, have been incorporating Jokaero into their retinues of Acolytes, where they make use of the Jokaero's innate affinity with technology. In the midst of battle the Jokaero can modify and manipulate the weapons and armour of the Inquisitor's retinue. These alterations may just be a simple aesthetic change, but certain Jokaero upgrades can modify the munitions of the altered weapon to massively and unexpectedly increase the weapon's damage. The creation of force fields and the use of unexpected and potent Jokaero imaging technologies to increase the accuracy and rate of fire have also been created on the fly by the Jokaero. Jokaero are also known for achieving wonders in the miniaturisation of advanced weapons technology, as Jokaero Digi-weapons are highly sought-after across the Imperium, and influential Imperial nobles, Rogue Traders and Inquisitors have spent small fortunes in order to obtain them. Such weapons visually resemble a large ring, but the most potent ones pack the punch of an Inferno Pistol, despite such a diminutive casing.
