Known as Hekatonkheires or Hecatonchires, they were giant beings from Greek myth. Having one hundred hands and fifty heads, their father Ouranos found them disgusting and threw them into Tartarus. Eventually, Zeus would free them and they would aid the gods against the Titans.
Hecatonchires can be encountered as a boss by using Kymopoleia's Hair Accessory in Shinjuku. The boss, who is known as Defender of Abaddon Hecatoncheires, has a small chance of reflecting any physical attack and will always reflect fire. Rarely, he will drop an Abyss Seed. Turning this in to the Yagiya on Suginami Tunnels' gold-level instance's final floor will give players the ability to fuse Hecatonchires. He is fused through a special triple fusion of Ubelluris, Cyclops and Ogre.
