The final battle at hand, Void takes his first steps toward a new age. In place of tyrannical rage, will he find... naptime? Gentle breezes? Treats? He may even dream again... a dream of friends reunited!
— VS Void • Kirby Star Allies

Void, titled as Astral Birth, is a boss appearing in Kirby Star Allies. He is the final boss of The Ultimate Choice on the Soul Melter EX difficulty, replacing both Void Termina's final phase and Void Soul.

Physical Appearance

Void is a spherical entity, similar to Void Termina's inner core and Void Soul. His body is now white and less reflective, with rainbow-colored veins pulsing throughout it. His Dark Matter form now has a blood-red eye, making Void appear similar to an old enemy.

General Information

Void is a celestial and mysterious being that is described in numerous books, namely the book of legend. Void is omnipresent, as he exists in infinite dimensions in different forms. According to the book of legend, depending on the energy gathered, Void could be brought into existence in a variety of forms, each being infinitely stronger than the last. One such form is Void Termina, which was reincarnated from darkness and negative energy. In the Japanese version of Void Termina's second phase’s Soul Melter EX description, it is implied that Void was created from the combination of all chaos and possibilities, Dream, Dark, Soul, and Heart, in a substance of sorts. It is also stated that he was born as “the progenitor of origination." Seeing a radiant form of his that resembled a star, the ancients, people of the past who made legendary treasures and pieces of technology, transcribed his mysteries into the aforementioned books, as well as possibly the book of legend. According to the book of legend, Void Termina's originator, the Jamba Heart, which apparently came from a dimensional rift,[1] was producing darkness, and was trapped in a seal by four heroes of yore using spears of the heart. Afterwards, the four heroes mysteriously vanished and were never seen again.

In the present time, Hyness had founded the Jambastion Religion, which worships Void and considers him to be a god. He founded the religion based on a vision he had, in which a god was speaking to him, inviting him to a new and peaceful land. He believed that Void was this very god, due to his vision matching with the book of legend’s writing about Void. The very same Jamba Heart that was sealed by the four heroes was somehow obtained by the Jambastion Religion, as it was the vessel Void would descend from and give his benevolence, as told in the book of legend, and Hyness wanted to resurrect Void as Void Termina by breaking the seal on the vessel so he can use his power to restore his clan. However, after Hyness became obsessed with worshipping him and taking revenge, his goal changed to using Void Termina’s power to destroy the multiverse to avenge his clan. Hyness proceeds to attempt to break the seal and resurrect Void, but did not fully understand how to break the seal, and accidentally shatters the Jamba Heart, sending its shards across the galaxy. The religion had gathered most of the shards, but after Hyness is defeated by Kirby and friends, he sacrifices himself and The Three Mage-Sisters, successfully completing the Jamba Heart and reviving Void, who reincarnates into Void Termina, due to the negative energy that was gathered. However, Void Termina was later vanquished by Kirby and friends.


Void begins his battle by firing energy pellets around him, similarly to his previous incarnation, but this time he fires many more pellets and immediately follows up by firing laser beams in a circular pattern from his body. His cutter attack is also more threatening, as he moves much more quickly while performing it. When he launches the cutters for the third time, he will shoot many cutters wildly around himself in a manner resembling one of Drawcia Soul's attacks.

Like Void Soul, Void can summon purple liquid. However, he does not electrify it; rather, Void utilizes it while jumping around, making it difficult to dodge the attack. He will then split himself into four copies (which share their health bar), all of which retreat into the background so they can bounce around the room and jump onto the foreground, just like Void Soul. Instead of jumping onto the foreground one at a time, though, they will jump in two at a time. After this move, Void and his clones float to the foreground and use a needle attack identical to that of Miracle Matter, doing this at the top and bottom of the arena before reforming into one being.

Void's Dark Mind-esque attack

Eventually, Void will begin to use moves reminiscent of those from previous final bosses in the Kirby series. Void grows in size and begins to rotate glowing, mirror-like projections around his body, similarly to Dark Mind’s second form. He will then rotate 90 degrees and fire a laser at the projections, which reflect the beam around the arena; the laser reflects about seven times, and can be avoided by crouching. After this, Void grows slightly larger and becomes a glowing ball, similar to one of Drawcia Soul and Soul of Sectonia's attacks. He will sweep from left to right, right to left, left to right diagonally, and then right to left diagonally before finally attempting to ram into Kirby from the background, this attack changes the background to a fierier scheme.

After these attacks, Void will use his laser attacks; he swoops in from the sides of the screen in a much larger arc, causing the lasers to take up more space. Three orbs will be created at the top of the arena, and three more will be created at surface level, each firing a damaging laser. To evade the beams, the player(s) must quickly move to the top or bottom of the arena or behind the lasers. After that, he will then fire beams from the background, which rotate around the foreground. They cannot be blocked, much like Void Soul's lasers. After that, Void then replicates another of Dark Mind's attacks, rotating his mirror-like projections in a figure-8 pattern while moving downward and then firing a laser at the projections again. After this, he will move into the background and begin sweeping across the screen once again, this time, changing up his pattern. He dashes down the right side of the arena, then speeds upward from the middle, and then he dashes down the left side of the arena.

If the battle is still continuing at this point, Void will continuously use the same three attack patterns (the Dark Mind-esque attacks, the Drawcia Soul/Soul of Sectonia-esque attacks, and the Dark Matter-esque attacks) until he is defeated. It should be noted that Void's laser beam pattern will change three additional times and will get more difficult to evade if he is still alive.

The battle with Void is non-canon, as it takes place during a non-canon sub-game. However, Void’s existence, affiliation with the ancients, the Jambastion Religion worshipping him, and his reincarnation into Void Termina are indeed canon.

  • Void's splash screen background is the Hyper Zone background seen in Boss Butch from Kirby's Dream Land 3. This is likely because his design slightly resembles Zero (And, to a lesser extent, ).
  • Void continues the trend since Kirby: Triple Deluxe of having a final boss that takes the likeness of previous characters in either attacks or appearance (the other ones include Soul of Sectonia, Star Dream/Star Dream Soul OS, and King D-Mind, who use the likenesses of Marx and Drawcia, Galactic Nova, and Dark Mind respectively).
  • Upon defeat, Void smiles instead of looking as if in pain and stars fly out of him instead of just light. This could mean that Void Termina is finally truly purified after being defeated for a third time.
  • In Void’s pause screen description image, Void has a face identical to that of 0²’s “angel” face.
    • Void also makes the same face randomly during his battle.
    • The position of Void's "smile" in the pause description image makes it resemble the image of Zero seen in the Boss Butch credits sequence.
  • Void has a unique battle theme when compared to his other two lookalikes. His theme starts off with the usual theme for the core form, being a metal remix of Green Greens and the Song of Supplication, but then it turns into a sad, somber, and partly 8-bit remix of the theme.
    • It is also the longest music track in the entirety of the Kirby series, tied only with Fecto Elfilis's battle theme, lasting roughly about six minutes and twelve seconds before looping.
    • Additionally, the 8-bit rendition of Green Greens occurs roughly four minutes and 27 seconds after the new segment of the theme begins, possibly a reference to Kirby's Dream Land’s initial release date.
  • Void does not turn Kirby's friends against him, unlike Void Termina's core and Void Soul. He also doesn't create miniature versions of himself that try to suck up Kirby and friends.
    • Despite this, he can still be damaged by Friend Hearts.
      • However, if he enlarges and uses either his Dark Mind-esque attack or the glowing ball attacks, the Friend Hearts are unable to damage him.
  • When Void performs attacks based on other final bosses, the background and his body change to match the bosses that his attacks are referencing; when using a mirror attack based on Dark Mind, Void gets bigger and turns slightly orange while the background turns red; when using his laser attacks, Void’s body, apart from his eye, glows a bright white while the background turns blue, possibly referencing Zero; when using a fireball attack based on Drawcia Soul, the background turns an orange-yellow, although his body turns black with his rainbow veins the same rather than matching the appearance of Drawcia Soul (or that of Soul of Sectonia, who also uses this move).
  • Void’s name is another synonym for zero, in which both mean a state of absolute nothingness. The leaders of the Dark Matter in Kirby's Dream Land 3 and Kirby 64: The Crystal Shards happen to be named Zero and 0² (Zero Two). However, this does not mean Void is another Zero, but it could be a reference used to further cement their connection.
  • Void is the first boss to be a tougher version of a "Soul" final boss, and is also the first secret final boss in an arena-esque sub-game since Kirby Super Star Ultra to not be a "Soul" boss, the one in Kirby Super Star Ultra being Wham Bam Jewel in Helper to Hero.
  • Void is the only character in the Kirby series to usurp the title of true final boss from another character, namely Void Soul. This is due to the way Kirby Star Allies had content patched in after launch, something rarely done in the series. No other Kirby game has added bosses in updates.

The black orb and the streaks of darkness.

  • In a video by the Kirby Star Allies The Original Soundtrack YouTube Channel, a pulsing black circle and streaks of darkness are visible in the background of the arena. These are absent in Void's in-game battle.
  • When defeated while performing any attack that creates duplicates of itself, Void still explodes as usual. His clones, however, vanish without a trace.
