Cerberus served as the gatekeeper of the Demon Castle and stood as its very first boss. An A-Rank magic beast shaped like an enormous three-headed hound, he overpowered Sung Jinwoo when they clashed and dropped valuable items upon his defeat.
Drawing on the three-headed hound of Greek legend, Cerberus took the form of an enormous black dog whose six red eyes glowed and whose fangs jutted prominently. The leftmost and central heads sported fiery orange manes and brown horns, while the head on the right was draped in a gray mask and ringed by brown fur.
Ranked as an A-Rank magic beast, Cerberus combined heavy strength, durability, and speed. His superior power left him entirely unaffected by Kasaka's Venom Fang, and he had little trouble getting the better of Jinwoo in their fight. His notable skill, Rage, doubled his own strength for stretches of up to three minutes at a time.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....

Five Bleach female characters, ranked and settled. Yoruichi sits at number five, the spot nobody expects, and our number one is an Arrancar with a soft heart....
