Royal Ripper

Royal Ripper (キリサキング, Kirisakingu; Viz: King the Ripper) was a member of the Monster Association and an infamous Mysterious Being of urban legend. He was killed by Garou.

Appearance
Royal Ripper was a humanoid monster wrapped almost completely in bandages, having exposed only his right eye and his long dark disheveled hair. Over his wrappings, he wore a worn-out tattered red dress and flat black shoes. Instead of hands, he had a pair of long and sharp straight blades that he sometimes used to scratch the floor in a menacing manner. Royal Ripper's inside was nothing like that of a normal human, but a mixture of hair, blood, and gauze.

Personality
Royal Ripper was a sadistic monster with a very strong drive towards torture and killing. He was shown to get excited over cutting apart anyone, enemies and allies alike. He experienced intense sadism towards children, and Black Sperm was not surprised when Royal Ripper disappeared with Tareo, remarking that "He couldn't hold back his urges." Phoenix Man described him as an "a one-of-a-kind psycho who kills for pleasure," so much so that even other monsters avoided going anywhere near him.

He even stated to Tareo that he didn't care for the Monster Association, as his only goal in life was to slaughter other creatures.

He was very psychotic, yet childish, referring to his fellow monsters with honorifics in a rather playful manner. Although he enjoyed toying with his opponents, he could easily be overwhelmed by his killing instincts as shown when he attacked a distracted Garou from behind and continued to viciously slash at him despite the latter already being down.

Monster Association Arc
Royal Ripper attempts to murder Narinki's Private Squad before Do-S stops him. Gyoro Gyoro later sends him and Bug God to watch and see if Garou can fulfill his mission assigned by Orochi.

Royal Ripper confronts the Hero Hunter when he questioned whether he was truly a monster. As proof of Garou being a monster, Royal Ripper demanded Garou to murder Tareo. However, Royal Ripper's urges for killing children soon take over, ultimately resulting in Royal Ripper and Bug God fighting Garou.

Despite the combined efforts of Royal Ripper and Bug God, Garou managed to fend them off. However, Sludge Jellyfish took Tareo hostage, distracting Garou and allowing Royal Ripper and Bug God to attack. After cutting Garou severely, Royal Ripper is stopped by Bug God. Believing Garou to be dead, Royal Ripper leaves with Bug God and Sludge Jellyfish, with Tareo as a captive.

Royal Ripper takes Tareo to the Monster Association base and puts him in the same cell as Waganma. He tells the two to play nice, and momentarily leaves in order to regain his strength. He eventually returns to the cell and chooses Tareo to torture for his pleasure. After threatening the boy, he decides to begin the torture but is interrupted by Garou. Garou breaks through the wall and quickly kills Royal Ripper by punching off his head and using the Whirlwind Iron Cutting Fist to rip his body apart. After his death, his bandages are used by Garou to wrap his wounds up.

Abilities and Powers
As a Demon-level threat, Royal Ripper was a rather powerful monster. Along with his partner, Bug God, he was able to fight on equal footing with Garou for a long period of time. However; Garou stated that Royal Ripper was nowhere near Bang's level and believed that he could have been able to defeat them. He also managed to put the Hero Hunter in a near-death state, albeit the latter was caught off-guard and Royal Ripper himself was injured during the battle, as noted by Gyoro Gyoro.

Physical Abilities
Immense Speed & Reflexes: Being a Demon-level monster, Royal Ripper was naturally fast. He was able to swiftly kill the monsters attempting to attack Narinki's Private Squad. He was also able to keep up with Garou and managed to sneak behind him, while the latter was distracted, and land a serious slash.

Immense Strength: As a Demon-level Mysterious Being, Royal Ripper was very powerful. He was able to slash apart multiple monsters with his blades, and along with Bug God, he was able to defeat and put Garou in a near-death state, albeit with the help of a distraction.

Enhanced Senses: Royal Ripper was capable of smelling the presence of humans near him.

Joint Reallocation: Royal Ripper has been shown to reallocate his joints to have movement with more degrees of freedom. This allowed him to move his blades more freely while making his blade arms less of an inconvenience.

Fighting Style
Expert Swordsman: Royal Ripper was extremely skilled with the blades that are in the place of his hands. He made multiple erratic slashes in combat.

Trivia
