"This is your true existance, mouse! An endless nightmare from which you will never awaken from!"
- Phantom Blot to Mickey Mouse just before his final battle in Enchanted Dominion.
The Phantom Blot is a major antagonist in the Kingdom Hearts Unlimited Saga, serving as an ally to Maleficent and her Hellfire Organization, as well as the leader of the Elite Dominion, a small group of dark-heartened individuals who were gathered together by the Horned King to serve as his candidates for the 13 Seekers of Darkness while he had Maleficent gather the 10 Princesses of Heart to open the Final Keyhole.
Before Birth of A New Era
(Ties into the Chernabog-Darth Sidious-Maleficent-Horned King mythos)
The Fantasmic Dreamtime
The Phantom Blot wears dark clothes that make him resemble a living ink-blot, or a shadow, hence his name. His mask sometimes has a mouth. Without his mask, he is a dog with a long black mustache and black slicked-back hair. His ears are the same color as his face, and he has a large black nose.
The Blot is very vain and his desire for money and power is only surpassed by his desire to immortalize his name in "the annals of crime"; although he often desires wealth and power, his greatest lust is for fame. Some of his plans have no monetary gain for him, but their purpose is to spread fear of him to the public, adding to his reputation. He seems to do evil schemes simply to be evil, and to spread his reputation as a villain.
He is very cunning, and can come up with hundreds of different plans, from stealing all of the money in the world, to murdering Mickey Mouse. He can be vengeful, as he sometimes creates plans to destroy or otherwise harm Mickey Mouse because of all the times the mouse foiled his plans.
Despite his ruthlessness, he has been known to occasionally show a softer side. In his first appearance, he claims that the reason he left Mickey in traps to die instead of just killing him was because he can't stand to actually see someone die due to his soft heart. However, on his criminal record file in the Disney-Land archives, he is described as having a black heart, suggesting he may have changed since then, becoming a more hardened criminal.
