Jokaero lore is interesting because while they have no discernable language, they somehow can craft weapons of amazing potential.
Who doesn’t love an Orangutan working for the good of the Imperium? We sure do! While they can’t communicate very well with the Inquisitors they are attached to, they sure make up for it with their amazing weapon creations! Their innate knowledge of tech allows them to actually modify weapons and armor in the heat of battle. Get out your favorite monkey snack and let’s learn about some lore!
Manipulated by the Slaan?

It would almost make sense because the Jokaero have an innate ability to manipulate technology. They can create tech from the most rudimentary parts that can be used by almost any race. Where when a race like the Orks make something, they are almost exclusively the ones who can use it.
Use by Inquisitors

Why do they enlist them? Because they can modify armor and weapons in the middle of a battle to better defend against or destroy the enemy! Since it’s hard to actually tell them exactly what to do, sometimes the changes are merely aesthetic, and other times they turn simple weapons into killing machines. So, if you have one next to you, just better to let it do its thing! If your Lasgun starts blasting apart Chaos Cultists with ease, would you complain?
On top of that, they seem to make some of the best force fields anyone has ever seen. If you don’t want to die on a backwater world, best take a Jokaero with you! Lastly, they make some of the smallest and deadliest digital weapons ever. If they grant you a ring randomly one day, just be ready for it to blow stuff up!
