Hekatonkheires, also known by its nickname Koro, is a boss in Slender Fortress.


Seryu receives Koro when she became an imperial police. She is often seen with Koro since then. During the battle between Mine and Seryu, Koro suffered large amount of damage and was eventual bifurcated with Mine's Pumpkin, which made it unable to regenerate. Seryu then used a suicide bomb as her last resort in an attempt to kill Mine, taking out the entire valley, along with herself and Hekatonkheires.
