Alternate versions
BB Pele

MoonCancer (ムーン・キャンサー, Mūn Kyansā?) is a MoonCancer-class High-Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order. She also appears as an enemy-only Foreigner-class and Alter Ego-class Servant.



MoonCancer's True Name is BB (ビィビィ, Byibyi?), also called BB Pele (BBペレ, BB Pere?) and BBhotep (BBホテップ, BB-hoteppu?).[3] She has two components she has installed as a High-Servant.



The first component of BB is Pele (ペレ, Pere?), the immortal Hawaiian goddess who is the incarnation of the volcanoes of the Hawaiian islands. Pele is said to have been deeply in love with the demigod of pigs, Kamapua'a, despite abusing him.

As BB assimilated with the immortal goddess Pele, who was the incarnation of the volcanoes of the Hawaiian islands, her skin color turned into a tanned shade suitable for a tropical country and her personality became more aggressive.


The second component of BB is Nyarlathotep (ナイアーラトテップ, Naiāratoteppu?), an evil Outer God that can be called a trickster. It is a being from deep space that does not exist on Earth, and it is not even from the same universe originally. It is something that is able to entice every intelligent lifeform, toying with them and causing them to self destruct. BB came into contact with it through Chaldea's observatory, gaining some of its power and creating the "cage of time" in Hawaii. Her profile posits that she may not have even been in sync with the god, simply under the wrong impression with a sort of placebo effect.



A Kouhai-Type Devil Heroine appears gallantly from the Far Side of the Moon.

Abusing her Master
as a cheerful yet precocious Kouhai.

While she is a little devil who calls herself a "great devil", there was this sweetness of hers that could not be offered to the devil since she was originally a good child... but the BB this time is a bit different.

BB's First Ascension is a cheerleader who roots on for her Master, but as she moves into her Second Ascension and Third Ascension, her true nature begins to reveal itself.

BB, who installed the divinity of the goddess Pele who is "violent, selfish, and kills those who get involved with her" has become "an S goddess who drives those dearest to her to death".


Fate/Grand OrderEdit

Serva★Fes 2018: Servant Summer Festival!Edit

BB was the organizer of the Servant Festival, having obtained power from Pele and Nyarlahotep, and combined the Hawaiian islands into one, which she named Luluhawa.[3]


In this form, BB has taken in power from two other entities; Pele and Nyarlahotep. The power assimilated from the former grants her authority over Hawaii, while the power bestowed from the latter allows her to loop time.[3]


BB's Class Skills include Territory Creation (A) and Existence Outside the Domain (B). She also has One Who Swallows the Land (大地を飲むもの, Daichi wo Nomu Mono?) (EX) and Divine Core of the Goddess (A). Her Personal Skills include Self-Modification (EX), Aurea Pork Poculum (A) and Faceless Moon (EX).[4]

Aurea Pork Poculum: Golden Pig Grail (黄金の豚の杯
, Kogane no Buta no Hai
Aurea Pōku Pōkua
?) is the Hawaiian version of BB's Aurea Poculum. It is connected to the goddess Pele, who deeply loved Kamapua'a, the demigod of pigs, despite abusing him, and has given BB an affinity to treat her favorite partners as piglets. Unlike Aurea Boura, it is used on BB herself. When she drinks from it, BB's S switch is turned on.[4]


Faceless Moon (無貌の月, Mubō No Tsuki?) is a skill connected to the second divinity installed into BB's Saint Graph - the lingering scent of a god, that drives humans to destruction as a test, with the third eye. A Reality Marble which makes the boundaries of Imaginary Number Space clearer and casts the surroundings into the Shadow Phase: Far Side of the Moon (月の裏側
, Tsuki no Uragawa
?). When the world is shrouded by the moon's shadow, everything will be frozen in time.[4]

Noble PhantasmEdit

BB's Noble Phantasm is Cursed Cutting Crater.[4] The hole of curses pouring unto the world, used by BB who has synchronized with the Moon Cell in "CCC".

She transforms the surroundings into the space of imaginary numbers by enlarging its own shadow, ranking down the world and its life entities into that low-dimensional beings. A space of madness and she herself, manipulating them as the ruler.

The original BB's Noble Phantasm was a surgery
in a "cute, fun, yet cruel nurse clothes" to defeat the enemy, but this one is a serious operation in which BB uses her ability to its full potential.

As the inventor of the Horror-Type Heroine, it is the attack of the last boss who uses the motto of: "Large-scale, scary, and seriously dangerous".

BB, who becomes a massive high-dimensional being, scoops out the earth easily and invades the world. Just like how a spoon scoops out some pudding.

... It is said that the installed second divinity reveals itself only in the Third Ascension Saint Graph...?
