Jokaero are heavyset, orange-furred apes with retractable fingers and toes, similar in appearance to the orang-utans of ancient Terra. Yet this primitive appearance is completely misleading. Jokaero are technosavants without peer and have an instinctive understanding of machinery and technological systems.

So great is their skill that they can customise almost any weapon or equipment, giving a group of Henchmen more powerful weapons, better protection or even both at the same time. While outwardly they appear to be unarmed, Jokaero digital weapons can prove to be deadly, whether they choose to use a powerful laser, a flame thrower or a devastating melta weapon.
