Ridai is unlike other Ustelu because of his augmentations, an M-Vial powered vocal cord and breathing apparatus requires constant attention, his eyes are stolen are a blank metal facade that never blink and his breaths are a constant grating of metal on metal.
Ridai is also often backed by two Tammroudou bodyguards, far taller than him and probably still taller than anyone he might run into. They are armed with their native knives and Supremacy exclusive firepower.
History:
Ridai was once a regular supporter of the rebellion, his hunter for change was fuelled by his indomitable greed for promotion, respect and power. The rebellion was a means to an end for Ridai, and when he found himself on the receiving end of a bomb meant for the higher-ups he took the only response that would almost guarantee a promotion in Trashtown.
The cost of saving them took his jaw, eyes and vocal cords from him. When he expected to be treated like a prince for his valiant sacrifice, he was treated like a regular hero and worst of all, he wasn't miraculously commended and promoted for the things he had done.
Ridai betrayed the rebellion without a single word, giving his knowledge freely to the Supremacy and casting in with them, and adding a personal vendetta towards their leader. Now his actions have repercussions, but he has yet to see them.
