Maleficent (KH III: Reconnect)

The Mistress of All Evil, Maleficent has returned from her defeat in KH 3D to finally begin her plot to conquer all worlds by capturing the 7 Princesses of Hearts once more to open Kingdom Hearts itself. But now, she's discovered that there are MORE princesses of Heart in the galaxy than what was originally thought to be. Her hatred and spite have given her greater control over the Heartless and Nightmares, as well as the newly arrived Heart Eater clan and returning Goblin Goons. She's even gathered new allies to replace her fallen comrades.

In her alliance, Maleficent has an exclusive army of Heartless and Nobodies specific to her powers.
