The Iron Man army had originally been the Radam tribes' elite fighting force, but Xiao Ran had clashed with the Iron Men long ago. Those Iron Men controlled by Radam bugs had virtually no mental strength to speak of, and perhaps because they controlled the Iron Men, the bugs themselves were also mentally weak. One Mental Shock from Xiao Ran could kill them by the dozens.
When dealing with the Radam tribes this time, Yuzes and the others, with their immense mental strength and psionic power, found it absurdly easy to handle the Iron Men. As long as they could kill the bugs inside an Iron Man's body or drive them out, that Iron Man would break free from Radam's control and regain their consciousness.
Through this method, Yuzes and the others gradually turned Radam's strongest fighters into their best allies. Many Iron Men had been forcibly transformed by Radam into combat weapons, and once these Iron Men regained consciousness, the first thing they naturally wanted was revenge against Radam. Thus, without hesitation, they joined the Burning Legion, Radam's enemy.
However, further discoveries revealed that not all Iron Men were truly controlled by Radam bugs. Some had simply been completely modified and brainwashed into Radam warriors—nothing more than War Weapons whose thinking had been thoroughly altered. Even if they retained their former memories, their minds had been completely changed, leaving no possibility of returning to their true selves. They were just like the Iron Man Xiao Ran had encountered on Earth and destroyed first.
Iron Men controlled by Radam bugs were generally those with greater potential and higher ranks. In other words, high-ranking Iron Men were certainly parasitized and controlled by Radam bugs, while lower-ranking Iron Men were not necessarily so.
