So, as we all know, the agent Killjoy is a genius inventor who is the mind behind many technological weapons for the Kingdom organization. She has quotes implying that she built everything on the playable battlefield, especially the ones trying to kill them. This includes Kingdom technologies such as the spike, a detonating weapon used for stealing all the radianite within the vicinity of the blast zone. She also created the arm tablet used by the agent Brimstone, a soldier for the Kingdom organization. Now, for KAY/O. KAY/O is an automated killing machine from our very own Kingdom organization. But who in the Kingdom organization is specialized in robotics? That would be killjoy, the inventor and user of two different drones used for combat. It all adds up, right? But here's what doesn’t make sense. Why does this robot wear pants? The training ground robots don’t have any pants, and there's nothing there. So really, there’d be nothing for him to hide. Unless, there was. It’d only make sense for KAY/O to cover up if he had something to cover up. This is why it's almost certain the KAY/O android has had uses besides killing. More specifically, KAY/O had to have been a sex robot designed and used by Killjoy. This is also the reason for its human-like appearance. A robot built for war would have weapons built in, would it not? But it doesn’t. Why would it have weapons built in if it was built for keeping company with a lonely girl in a workshop?
