On the day of judgment, this fluttery fiend will fly into action. Brought into existence by “the greatest warrior in the galaxy” and reborn as a knight of doom through years of adversity—now begins an epic battle with a pure being twisted by a dark past.
— VS Morpho Knight • Kirby Star Allies

Morpho Knight, titled as Reborn Butterfly, is a boss appearing in Kirby Star Allies. It is the final boss of the Guest Star ???? Star Allies Go! mode. When playing as The Three Mage-Sisters in Guest Star ???? Star Allies Go! and in The Ultimate Choice's Soul Melter EX difficulty, it appears in a more powerful form known as Morpho Knight EX, titled as Dark-Winged Disaster.

General Information

While most information is left ambiguous and mysterious in the English versions of Morpho Knight and Morpho Knight EX’s pause screen descriptions, the Japanese versions give more details about what Morpho Knight actually is. The butterfly that is seen before Morpho Knight’s birth is described as a “butterfly of paradise,” and it appears in the present time after something has “ceased to be.” Along with the constant mention of “judgement day” in Morpho Knight’s pause screen descriptions, as well as its regular battle theme title, this seemingly implies that the butterfly is a being of judgement of sorts that decides the fate of those who have perished, although this is not confirmed.

However, in Japanese mythology, butterflies are often associated with death and spirits, where they are sometimes believed to be guides of the spirits of the dead that take them to the afterlife, akin to a psychopomp, and seeing as how Morpho Knight is a butterfly, this appears to support the implication that it is associated with death. The butterfly is also stated to have the ability to cross dimensions into other worlds. After Galacta Knight, the greatest warrior in the galaxy, emerges from the portal created by Hyness, the butterfly flutters down from another dimension and resonates with the “screams of the many years spent living” that Galacta Knight has brought with him. It then absorbs Galacta Knight’s power, seemingly disintegrating him in the process, and is reborn as a “knight of the underworld,” going by the name of Morpho Knight.

Morpho Knight EX is the form Morpho Knight takes when it has mastered its new abilities after amplifying the power it has inherited from Galacta Knight to make it its own.

Physical Appearance

Morpho Knight

Morpho Knight is a spherical creature with black skin, white glowing eyes and no mouth. It has yellow shoes and gloves. Its armor is red with black ornamentations and white shoulder pads with a red swirl on both of them. Its mask has horns which resemble antennae. It has red sparkling butterfly wings on its back. It wields a sword that looks similar to Galaxia, but it has a red and gold coloration with a butterfly pattern on its handle, with blue spots on both sides of the tip of the sword. What appears to be a gemstone can be seen on the handle, which has a thin black line across it, giving it a similar appearance to a snake's eye.

Morpho Knight EX

While Morpho Knight EX's physical features remain the same as its original incarnation, the color scheme has been altered to a mostly black body with a red blade, red eyes and wings, and purple highlights on its mask and shoes. Its blade also has an eye that resembles the ones that mark Void Termina's weak points.


Morpho Knight

Morpho Knight acts just like Meta Knight and Galacta Knight in that it uses sword attacks, but Morpho Knight's sword is imbued with fire. If a friend has a Sword ability, they can deflect its sword attacks by attacking him, making their swords clash and causing it to flinch. However, one unique move Morpho Knight has is its ability to teleport. Additionally, Morpho Knight can fly to both sides of the screen, charging its sword, and emitting two giant ghostly faces. Also, Morpho Knight can charge and release sound waves from its wings that turn the leading player’s friends against them, similar to what the core of Void Termina does; a Friend Heart must be thrown at the confused friends to return them to the leading player’s side. Morpho Knight may also slice forward and then up, trapping Kirby and his allies in the air while performing a series of slashes on them before slicing them back onto the ground, dealing massive damage. Also, in its second phase, it creates a second sword, teleports to one side of the screen, and enlarges one of them. It then swings it forward, damaging anyone behind it or in front of him. It then repeats this on the other side. After that, it teleports to the center, enlarges both swords, and swings them down on each side. Morpho Knight can also teleport around the arena releasing sound waves whenever it appears. In the second phase, among with emitting two ghastly faces, it can instead emit one huge ghostly face, then fly to the other side of the screen and summon another one. Additionally, it can create one to four tornadoes, depending on how many players there are, that head into the background and then charge into the foreground one at a time, similarly to Meta Knight's and Galacta Knight's Mach Tornado.

Morpho Knight appears in the game's boss rush mode, The Ultimate Choice. It appears in the original three highest levels of difficulty (Fiery Showdown, Infernal Crisis and Soul Melter).

Morpho Knight EX

Morpho Knight EX retains most of its old moves, but uses them at a faster rate and teleports more often. It should be noted that when it teleports, it leaves behind a small wave that can damage Kirby. Some of its old moves have also been altered to deal more damage or to be more difficult to avoid. Instead of releasing two medium-sized ghastly faces from its sword, it releases a large number of smaller faces that sweep across the battlefield in an arrow formation or a wave formation. It also gains Parallel Meta Knight's counter ability, but instead of retaliating with a swipe of its sword, Morpho Knight EX responds with its trapping aerial slash technique, which is far more damaging. When Morpho Knight EX is preparing to swing its enlarged swords, it summons small vortices that pull Kirby and his allies towards the area where the swords will strike, making it more difficult to evade the swings. Finally, instead of creating a number of tornadoes proportional to how many players there are, he summons five tornadoes that remain in the background before one at a time charging into the foreground.

Morpho Knight's name may hold multiple meanings. "Morpho" means "changed" or "modified," referencing how the butterfly transforms into Morpho Knight upon making contact with Galacta Knight, or the process of metamorphosis through which caterpillars transform into butterflies. Morpho is also a genus of tropical butterflies, which can be a variety of colors; some, such as the Morpho hecuba, appear in an orange color. However, it should be noted that Morpho butterflies have ocelli (eyespots), which Morpho Knight's butterfly form lacks, and Morpho butterfly wings don't have tails, unlike Morpho Knight's.

Its Japanese name, バルフレイナイト (Barufurei Naito), may be a portmanteau of Valkyrie, バルキリー (Barukirī); and butterfly, バタフライ (Batafurai). ナイト (Naito) simply means knight.

The original artwork of Morpho Knight

  • Morpho Knight's design was first shown in the Japanese 20th Anniversary booklet. Because it was shown in Meta Knight’s section, many assumed it to be a beta design of Meta Knight. However, in a Nintendo Dream interview with Shinya Kumazaki, he confirmed that the design was originally for an entirely different knight that would have appeared in the cancelled Kirby GCN.[1] Its design remains unaltered in Kirby Star Allies, though its sword and wings slightly differ.
  • While the English localization makes it unclear whether or not Morpho Knight is the butterfly itself or a fusion between it and Galacta Knight, the Japanese version makes it much clearer that Morpho Knight is the butterfly and not a fusion.
  • Morpho Knight's butterfly form is nearly identical to the orange butterflies that are seen in several of the newer Kirby opening and ending cutscenes. Whether Morpho Knight was of those butterfies, in particular, is unknown.
  • While real morpho butterflies are usually blue, Morpho Knight is mostly red, and resembles a Monarch Butterfly more. However, female Morpho butterflies are a brownish-orange color, and some species are orange or brown rather than blue. The design of the wings also shows that Morpho Knight is a Morpho butterfly as very few butterflies have that specific shape.
  • Morpho Knight's battle theme has a similar beat to Meta Knight's battle theme from Kirby Super Star.
  • When playing as one of the Dream Friends in Star Allies Go! Go! and Soul Melter EX (though in the latter, this only occurs if there is one player, any more players will result in the default theme being used instead), different music plays while fighting Morpho Knight. As such, Morpho Knight has a total of 12 different battle themes, which is the most in the Kirby series.
  • Each update had Morpho Knight's arena getting a revamp in design, which can be seen when fighting him as a Dream Friend in Star Allies Go! Go! and Soul Melter. The alternate arenas contain familiar locations in the center pool.
    • In the Wave 1 arena, Hyper Zone from Kirby's Dream Land 3 is visible in the pool.
    • In the Wave 2 arena, Dark Star from Kirby 64: The Crystal Shards is visible in the pool.
    • In the Wave 3 arena, Another Dimension is visible in the pool. This arena is also the default Morpho Knight EX arena in Soul Melter EX, regardless of character.
  • In Super Kirby Clash, an armor set and sword based on Morpho Knight and its sword appears as an armor and weapon, respectively.
  • Some of the concepts for Morpho Knight's sword resemble the eye and talons of the Master Crown (particularly around the sword's guard).
