Void Soul

Void Soul appeared in 2018 video game called Kirby Star Allies. Void Soul, also titled as Essence of Chaos​, is a boss appearing in Kirby Star Allies. He is the final boss of The Ultimate Choice on the Soul Melter difficulty, replacing Void Termina's core as the fourth phase of the Void Termina battle.

As of update 4.0.0, Void Soul's role as the true secret final boss of The Ultimate Choice was taken by a stronger form known as Void in Soul Melter EX.

Void Soul appears just like Void Termina's core, except he is now a bluish white. His Dark Matter form now has a blue eye instead of a red one.
