Void Termina

"The shocking true form of Void Termina has been revealed! Born from the total absence of care and composed of dark energy, he has awakened from a state of mere existence to that of true sentience. He now desires only one thing… to CRUSH all opposition!"

- Void Termina's battle description.

Void Termina is the main antagonist and final boss of Kirby Star Allies. He is a god-like entity worshiped by the Jambastion Cult that seeks to destroy all worlds.

Appearance
Void Termina's outer appearance takes the appearance of a large humanoid with grayish skin and a mane of black feathers on its neck. He wears a white heart-shaped mask on his head, resembling Sachiel from Neon Genesis Evangelion. He has flat feet with three toes on each and two two horns that stretch down his back. He wears gold armor around his waist, arms, feet, and shoulders, the latter of which drape purple tags.

Later, he ditches his limbs and takes flight, with his arms becoming wings with protruding white and red feathers similar to stained glass, and his lower body turning into a tail of Jamba Hearts. Void Termina's weakspots are eyes that open on certain parts on his body: first his belly, then his two arms, his back, and last his forehead. After all weakspots are hit, Void Termina collapses, his mask falls off revealing the opening to his core, which Kirby and friends must enter before he can get back up.

Inside is Void Termina's core, which is at first protected by a pink shell with yellow hearts flowing through swirls, and can partially open to shoot out tracking magical spells. His true core appears as a purple circular blob with three dark spots that move around and form faces of different Kirby characters, including Miracle Matter, 0², and even Kirby himself. As the core takes damage, it transforms into a Dark Matter, with the spots forming an eye and red pupil.

Void Soul resembles his regular counterpart, with the exception of his skin being paler in shade, his armor is blue shaded, and the tags are orange. His core is also white, with its eye now blue.

History
In the past, Void Termina was a force of destruction, spreading fear across the universe, until he was defeated by four warriors who used heart spears to seal his power. Afterwards, a race known as the Ancients rebuilt the world that Void Termina destroyed, creating legendary items to help the people adapt, including the Master Crown and Lor Starcutter. Those who still worshiped the deity were banished to the edge of the galaxy, eventually becoming a cult.

The cult obtained a vessel called Jambastion that contained Void Termina, and their leader, Hyness, believed he could revive the dark lord by collecting Jamba Hearts to fill in the missing parts of the Void according to a book of legend.

Their ritual backfires and the Jamba Hearts scatter across Popstar, causing calamity for the residents of Dream Land, though Kirby and a few others were struct by beneficial pink Friend Hearts, allowing them to calm down others who were possessed by the Jamba Hearts.

When they reached Jambandra Base, they were unable to stop Hyness' second attempt to revive Void Termina, sacrificing the Jambastion Mages and himself to fill in the missing Jamba Hearts, completing the ritual. However, before Void Termina could spread his evil across the universe once again, Kirby and his friends used the Friend Hearts they gathered to form the "Star Allies Sparkler", allowing them to battle and defeat the monster both externally and internally.

Void Termina makes one last attempt to blast his lasers at the heroes, but they manage to overturn his power against him, destroying the dark lord and saving the universe from his tyranny. A more powerful version of Void Termina can be fought in "The Ultimate Choice" sub-game at Soul Melter difficulty. He uses the same attacks only stronger variations, but contains a harder version of the fourth phase where Kirby and friends fight Void Soul, which fights similarly to the regular core phase, only it has much more health and rapidly moves across the stage unpredictably.
