Eto is the most powerful Ghoul seen thus far in the series, possessing an SSS ranking which she earned at age fourteen. She is very well-versed in manipulation, torture and psychological warfare, able to mentally break down a person's mind and force them to accept her ideas with ease through methodical torture. She possesses incredible agility and speed surpassing most ghouls, able to close large distances almost instantaneously and injure her opponent before they even realize it. Among her other assets she also possesses incredible resilience and regeneration, being able to survive grievous wounds such as being bissected in half and regrowing her lower body afterwards. Eto is much stronger than most ghouls, evident by her attacks in CCG headquarters and the number of investigators that she has killed as the One Eyed Owl. She easily subdues a team of high class investigators prior to Arima's arrival whereas Yoshimura had trouble fending off the same investigators' cooperative attacks. She is the strongest and most dangerous ghoul to date with 6-8 Kakuhous that help expand her kagune abilities. So far, only Arima and Kaneki have been capable of besting her in combat. Her maximum has yet to be seen.
