Monstrous Strength (怪力, Kairiki?) is a Skill that temporarily grants a rank-up to one's Strength Parameter for a limited time determined by the ranking of this Skill. It originates from the holder's nature as a monster or Demonic Beast.[1] It seems to degrade the more Divine Spirit aptitude the Skill holder has.[2]

Rank User(s)
EX Kingprotea
This Skill alone makes Kingprotea a threat. At the moment, the only Servants that have Monstrous Strength at EX Rank are Tiamat and Kingprotea.
A++ Tiamat
For Tiamat, also known as Beast II, this Skill is ranked expressed at its highest possible level. By assuming her Draconic form by way of reshaping the Black Mud of the Sea of Life, Beast II attains the Strength of a Titan.
A+ - A++ Magni
While possessing no special abilities, Magni boasts tremendous strength. He initially possesses an A+ Rank in this Skill, which changes to A++ after the activation of Twilight Survivor. [3]
A+ Gorgon
Sakata Kintoki
Kintoki is the son of RaijinWP as a red dragon and a cannibal mountain witch, giving a high rank in this Skill.[4]
A Asterios, Oryou
B+++ Surtr
The Skill represents Surtr's destructive nature as a world-ending giant. The "+++" is some kind of bug that shouldn't fall within the framework of his Saint Graph.[5]
B+ Caenis
B Hessian Lobo, Tamamo Cat
Henry Jekyll and Hyde (Assassin)
This Skill only manifests when Jekyll uses the Dangerous Game Noble Phantasm to transform into Hyde.[6]
Jaguar Man
Jaguar Man calls this Skill Jaguar Kick (ジャガー・キック, Jagā Kikku?).[7]
Medusa (Rider)
Medusa has this Skill due to her property as a monster despite being a Heroic Spirit. This is a necessary Skill for Medusa, who does not fight with Noble Phantasms in close combat. It has many uses with her chained daggers, such as forcibly dragging an impaled opponent around. However, the longer she is under the influence of this Skill, the more she turns into the legendary Gorgon.[1]
C Medusa (Child)
Medusa Lily's rank in this Skill is low because her demonic is not as strong compared to her adult form.[8]
C- Astolfo
When using this Skill, Astolfo takes damage every turn that passes.[9]
D Hassan of the Hundred Faces (Gozour)
This ability is Gozour's own Skill but its rank is quite low as a result of lacking any sort of demonic disposition.
? Henry Jekyll and Hyde (Berserker)
? (Above C Rank) Medusa (Saber)
Since Medusa's aptitude as a Divine Spirit has increased, her rank in this skill has degraded.[2]
