Despite having a kaiju living in his body, he still was some alien’s interest for their takeover and since he had some powerups than many exp suits that they’ve made, it was a good opportunity for them to get enhanced versions of them with Kafka.
Kafka got caught by one of the aliens on his most recent mission as he got immobilized and ready to be transformed for the alien’s sake with their advanced methods as this time they tried doing several changes into Kafka’s brain, removing certain parts of it mainly his prefrontal cortex to place the new control panel that will serve as its new cortex as it quickly gained mobility thanks to the removal of excess of brain zones that maintained Kafka’s thought process active.
Not late after one of the crew had one more suit for them to conquer earth for more male subjects to test on.
