Void Termina

Void Termina also known as the Destroyer of Worlds is an ancient cosmic entity that serves as the final boss of Kirby Star Allies. Void Termina is shown to be able to alterate his appearance greatly during its fight against Kirby. He is worshipped as a diety by Hyness, Zan Partizanne, Flamberge and Francisca who bare its insigna and were the ones who resurrected it.

History
Long ago, Void Termin was sealed by four heros with heart spears. An unknown amount of time later, people who are assumed to be the Ancients wrote a scroll about Void Termina. When they were banished, the four mages led by Hyness tried to obtain their revenge on the ancients by resurrecting the "Destroyer of Worlds" but he was ultimately defeated by Kirby and his allies. Void Termina is said to have taken various form during history and to be the source of all chaos.
