He's basically a three headed dog demon, whose two other "heads", are the swords, and his main one is his soul that accompains Sophia through them. Sophia defeated him, since he's regarded as a joke character in the Zero series, he was a devil king who was kicked out of his post due to other devil's ambitions or he was just too tyrannical.

Only few people can listen his voice through the swords, such as Sophia (his owner), Damien Close (supreme existence imo), Jet Dark (due to his cybernetics in the operation before taking the title after the Rising Phoenix events) and Joker (Arcana Warrior) in Dimension Bellum.
