Kraken is the final antagonist of the book series, Unicorns of Balinor. He is powerful with the Deep Magic, and is the dark counterpart to the Old Mare of the Mountain. Both are seldom seen. Like Entia the Shifter, Kraken possesses shifting magic. He is seen taking the form of a giant spider, a hooded figure, and in the eighth book is described as having a skeletal hand. After Kraken's defeat, Chase defeated Moloch, who surrendered to him, and at Ari's request Chase let Moloch escape.
