Cath Palug

Primate Murder (プライミッツ・マーダー, Puraimittsu Mādā?)  — also known as the White Beast (白い獣, Shiroi Kemono?) and Altrouge's Demonic Dog (アルトルージュの魔犬, Arutorūju no Maken?) — is a Monster of Gaia. Within the setting of the original Tsukihime series, he is the first of The Twenty-seven Dead Apostle Ancestors[1][2], but he is not listed as one in the Tsukihime Remake series.



Primate Murder is the form taken by Cath Palug in worlds where he was not able to obtain a different perspective on humans by staying with Merlin. Primate Murder came to be under Altrouge Brunestud's control at some point.[3]


Fou claims that if he were allowed to mature normally, he would degenerate into "an unsightly monstrosity." It's possible he would have horns, as all other Beasts do and Fou is sometimes depicted with horns such as on Fate/Grand Order's stat up cards. Lancelot and Gawain compare Cath Palug to Barghest's demonic hound form.[4]


Primate Murder has yet to appear directly in any works. Avenger briefly references it in Fate/hollow ataraxia, calling it a better murderer than himself.[5]


Primate Murder, the Murderer of Primates (霊長の殺人者, Reichō no Satsujinsha?), has the "absolute right of killing over man", a "super advantage" over primates, so it is counted amongst the world's strongest beings.[1][2][6] Compared to Angra Mainyu who would normally be the best existence at killing humans, Primate Murder, along with Type Mercury, is a better murderer who far surpasses him in terms of the speed with which it is able to kill humans.[5] It takes seven guardians to control it, and like Type Mercury, it is considered to be in a league of its own compared to beings like Servants and other Dead Apostle Ancestors.[6][7] It is owned by Altrouge and only listens to her, so she can be said to be a greater monster than Crimson Moon in a way.[2][3] While not a Dead Apostle, it has, in mimicking its master, developed a taste for human blood.[2]

    The Twenty-seven Dead Apostle Ancestors [Term]
    The 27 oldest Dead Apostles.
    There are the Ancestors of the Elder Title, whose age exceeds 4000 years, Ancestors sealed by the Holy Church, Ancestors secretly biding their time in the unexplored regions of the world, and even Ancestors akin to a family that passes on the throne to a successor every 500 years.
    They each have their own factions, and are engaged in vicious power struggles within them. Perhaps for them, this is one of the few things that gives meaning to their existence now that their sense for amusement has completely worn away.
    On rare occasions an Ancestor will die, but since there is always a successor to replace them, the number of Ancestors never changes. In fact, it could be said that becoming an Ancestor is the ultimate goal of all Dead Apostles. Even those Dead Apostles at the very bottom, who were changed into vampires by lowly Dead Apostles with no standing or reputation, dream of one day being able to gather enough power to become one of the 27 themselves.
    On the other hand, there also exist Ancestors who have no interest in such things at all. They are seekers, who eschew building a kingdom of their very own in favor of chasing after perfect immortality. There are many of these "Ancestors without a faction" among the Dead Apostles that used to be magi.

    Q: Who would be stronger if Servants fought the 27 Ancestors?

    Q: Who would be stronger if Servants fought the 27 Ancestors? Servant's also have superhuman battle ability, but the 27 Ancestors are also superhuman monsters.... I got the impression that ORT, Primate Murder, Altrouge Brunestud, and so on were obviously stronger than Servants.

    A: All I can is they're both powerful.... They're both beings that live in mystery, so the only thing that can be said is that it all depends on the situation the moment it comes done to ""having the means of killing the other guy somehow". Among those, Earth rules won't even apply to ORT in the first place and Primate Murder has the super advantage against primates so they're in a league of their own, I suppose. Speaking of which, for one Primate Murder, seven Guardians would be the appropriate amount.


    A:どっちもどっち、としか・・・・・・。どちらも神秘に生きるものたちなので、"なんとかして殺す手段がある"時点で状況次第としか言えません。そんななか、 ORTはそもそも地球上でのルールが成立しないし、プライミッツマーダーは霊長に対して超有利なので別格でしょうか。ちなみに、プライミッツマーダー1匹に対して守護者七騎であたるのが妥当なところです。

    Q: About the power comparison between Arc and Servants, would the Arc being compared be the 30% one or the full one?

    Q: About the power comparison between Arc and Servants, would the Arc being compared be the 30% one or the full one?

    A: That would be the 30% Arc. It takes 7 Counter Guardians to control the Primate Murder and the Servants of the Grail War are based on these.
