Giga is a giant shadow beast, which is really Lord Acriss's final form. The only way that he can turn into Giga is acting insane or getting extremly angry. He chases his victims and if he catches them, he turns them in Pitch Blacks. Giga is The Enemy's pet and kills anyone who tends to fight him.
He is 90 feet tall and has Beorn ears that are sharp and look like devil horns. His eyes are dark red and he drips shadow-like ink. He has a Genie-like tail and has claws on his hands.
