Saga Boss: Zel the Heartless King

Zelgor's life began long ago during the ending days of Galifrey, when he and Mikay were born on it and were known for being the grandsons to the first Heartless King, who had corrupted Cecil just days before Mikay would be born. Forced to go onto one of the gummi ships of Galifrey, Mikay was then born where his mother would then find her deathbed on the same place she gave Mikay to. Zelgor was then left to look over to Mikay, who he grew to love and care for.

However, as time passed, Zelgor began to notice Mikay growing more distance from him, as he would grow to hate this from Mikay. Eventually, Zelgor soon took to drastic measures, but ultimately failed to gain Mikay's attention or love. After the death of their grandfather, Zelgor would pull a prank on Mikay in which he would help become a heartless himself. This wasn't part of the plan, and it was an error on Zelgor's part he did not see come from Mikay. Zelgor now was known as Zel, and threw his hatred full onto Mikay and the ship, turning most of them into heartless. The only known survivor's were Mikay and his father, the later of which was never found after this event again.

Zel grew in power as the heartless returned to the universe, and eventually, Zel came up with a new plan in which he could get back at Mikay with. He now hated Mikay entirely, wishing he never was born, for cursing him into a life of this damnation. But the darkness grew onto Zel, and with it, the idea of the Keyblade's came to mind. Tricking Mikay into making them, Zel then snatches the prototype to the X-Blade and corrupts it to make it his own, creating the first Reverse Keyblade. The numbers of the Keyblade Wielders and Reverse Keyblade Wielders grew over time, and eventually, led to the Keyblade War. Zel's plan all worked out, which led to him attacking all the keyblade wielders, reverse and normal alike, in the end. Taking a few of the normal keyblade wielders hearts too, he left Mikay in depression.

However, Zel did not see him getting stopped and sealed away into the Realm of Darkness, where he has been for the last one hundred years. Zel now plays the cunning role while locked away behind the darkness, awaiting to execute his plans that he has been waiting thousands of years to finally put into reality.
