Gromm has four red eyes, with a skeleton-looking face, and massive body size. After the battle in the Last Station, Gromm was shown to have lost one of his arms due to Ha Cheonhee attack.
Gromm went along with the other servants of Karaka to the 44th Floor. When they arrived he was told to destroy the warship that was holding Karaka captive, but his arm was destroyed by Ha Cheonhee from a distance. She then threatened him about ripping off his head if he tried again.
Powers and Abilities[]
Gromm was about to destroy one of Zahard's warship, indicating he should be as strong as the other servants of Karaka.
