- Prosthetic Arm: After his left arm was destroyed by Chisaki in the "Shie Hassaikai Arc", Sako was given a functional robotic arm by Giran as a replacement for the lost limb. This one, however, was destroyed in the "Meta Liberation Army Arc", and was later replaced by a brand new one that also allowed him to shoot his "marbles" from his fingers.


Intelligence: Unknown (Despite being remarkably proficient in the art of "deception", the exact extent of his potential and abilities has not been shown)
Weaknesses: To use his Quirk on something or someone, he must touch that object or person. Following the events of the "Shie Hassaikai Arc", he lost his left arm to Chisaki, who destroyed it using the "Overhaul Quirk", and now can only use his Quirk with his right arm. He tends to brag about himself and explain his actions, rather than just getting away. He is also rather arrogant and tends to underestimate his enemies at times.
