WMG / Kingdom Hearts III Army Of Light

One of the leftover New Seven Hearts is Sofia, Princess of Echancia.

I mean, in the Grand Finale of her show, Sofia used the Light in her heart to obliterate an Expy of Ansem, Seeker of Darkness (named Vor, which is ironic, since Master Xehanort had a friend named Vor, as seen in Kingdom Hearts Dark Road), as well as the fact Sophia and Child!Kairi have the same voice actor.
