Jack "The Ripper" Smith | The World's Most Notorious Serial Killer (RoR)

Jack the Ripper is Humanity's representative in the fourth round of Ragnarok, going up against Heracles. Jack is also the main character of his spin-off manga, "Jack the Ripper's Case Files".

Jack is a serial killer hailing from late 19th century Britain and is a very important figure in the history of London, being considered "Humanity's Most Infamous Serial Killer" (人類史上最も著名な殺人鬼, Jinrui Shijō Mottomo Chomeina Satsujinki).

Jack takes the form of an adult man with silver hair and a silver moustache. Jack also has different coloured eyes, with a left eye that is silver in colour and a right eye that is deep red in colour, the latter being covered by a monocle filled with gears. He also wears a grey Victorian Era formal suit with a white shirt underneath and a blood red steampunk top hat. Jack also wears blood red trousers, a blood red coat over his suit and a pair of black gloves.

Normally, Jack has the disposition of a typical British gentleman, accentuated by his sophisticated diction and actions. He is also a big fan of Shakespeare, usually quoting some of his plays while talking to others.

However, underneath this polite and distinguished façade, Jack is a cold-blooded sociopath at heart as he gleefully murders people simply to bask in the sight of his victim's fear as they come face-to-face with death, even going as far as to describe the colour as "absolutely beautiful". Later on it's revealed that much of Jack's twisted, cruel, and sadistic nature comes from a traumatic childhood experience where, upon discovering that his mother never truly loved him and only saw him as a tool for her to get out of poverty, he broke down mentally and eventually spiralled until he became the ruthless killer he is today.

Jack is also a natural liar. He repeatedly lied to Heracles about his Völundr as a part of his strategy to win his fight against the god.

However, after his fight with Heracles and later meeting with Göll, Jack seems to have shown a desire to change and move on, as well as a want to meet someone who truly loves him. Also, despite his ability to see the true feelings of those around him, Jack has demonstrated an inability to recognize his own, even requiring Hlökk to tell him that he felt sad about killing Heracles.

Despite his twisted and ruthless nature, Jack still has some kind of moral and humanity, helping a secret organization while he was alive to get rid of the worst criminals of London, specially if they are related with orphan kids who are kidnapped by rapists. However he chooses to take over the identity of the actual Jack the Ripper as he sees himself not different from the original, telling to Brunhilde that he could've been just like him if the conditions were different of those he had.

Overall Abilities: Jack the Ripper is a master assassin and combatant who prefers to win through genius tactics rather than raw power. In battle, Jack is willing to use any means necessary to take down his prey, using his warped and creative mind to come up with a plan of action so as to kill his targets as efficiently and sadistically as possible. By using any and all items available to him, Jack can adapt effortlessly to his surroundings, quickly setting up complex traps and improvising to fool his opponent even when in the heat of battle.

Godlike Strength: Despite possibly being the weakest of the Einherjar when it comes to physical strength, Jack still is far more powerful than the average human being. He was able to overpower the Valkyrie and demigoddess Hlökk, rip off and throw the clock face of the Big Ben. During the battle with Heracles, Jack was able to deflect one of the demigod's club swings head-on using his umbrella and even briefly trade blows with Heracles when the latter was using his Twelfth Labor: Cerberus, Hound of Hades technique that enhanced his already formidable strength. In his spin-off series, he was shown to be strong enough to hold a cannonball in one hand, and throw it with such force, it went through Humpty Dumpty's torso, making a large hole in his torso.

Godlike Speed & Reflexes: Being an expert assassin and talented killer, Jack can move at superhuman speeds, although not at the same calibre as individuals like Adam or Kojiro Sasaki. Despite that, he was still able to throw his assortment of knives and blades with great speed which even the likes of Heracles couldn't completely deflect and block and keep up with the demigod's extremely swift attacks. When approaching Hlökk before the fourth round of Ragnarok, he was able to swiftly grab her throat and lifted her up before she could even react despite being right in front of him, though she did turn her attention away from him at the time when denying the partnership with him thus giving him an opening. In his spin-off series, Jack is shown to be fast enough to cut cannonballs in mid-air and catch bullets with his piano wire.

Godlike Durability: Despite being just a mortal, Jack was able to take multiple hits from Heracles, who's been stated to possess a calibre of strength on par with Zeus himself, and survive, however, he was heavily injured in the process. Even when Heracles managed to hit him with attacks while using his Twelfth Labour: Cerberus, Hound of Hades technique, Jack still managed to get up back in little time to continue fighting.

Godlike Endurance & Stamina: Jack has displayed incredible endurance and stamina, able to keep up with the God of Fortitude himself without showing any signs of fatigue, even after receiving multiple injuries he was still able to keep fighting. Even when he was impaled on his side when led to losing blood during the final course of their battle, Jack still managed to keep fighting Heracles and eventually win.

Immense Pain Tolerance: Jack possesses an immense pain endurance. When Heracles landed a successful blow on him with the Nemean Lion, Jack shrugged off his injuries unfazed and fixed his dislocated shoulder nonchalantly.[2] He also ignored his wounds from the knives reflected by Heracles' Bird of Stymphalia. When he was impaled on a metal fence, he cut off the spike, pulled it out of himself and continued to fight.[3] Arm Extension: With his pain tolerance, Jack can dislocate and elongate his arms. He used this ability to defeat Humpty Dumpty by using his elongated arms to throw a cannonball with enough force to kill him. Internal Organ Movement: Jack has the ability to slightly move his internal organs at his will in order to avoid critical even lethal damage. The extent of his organ movement is limited but just enough to avoid lethal damage from an accurate fighter such as Noah.

Strong Willpower: Jack the Ripper has displayed immense willpower, to the point that even Heracles himself praised his determination. Even after taking multiple hits from the God of Fortitude, Jack still remained determined to defeat his opponent always thinking of new plans in order to win. Jack was even willing to impale himself in order to gain an advantage in the fight.

Expert Tactician: Jack is very skilled at various tactics, being able to outsmart Heracles and the Gods and think on his feet, as shown when he used the urban environment to his advantage, fleeing into a dark alleyway and setting up traps.[4] He is also very crafty, as he was able to distract Heracles with the use of manmade weapons and traps along with hit-and-run tactics.[5] Jack was also able to catch Heracles off guard multiple times[6] and was even able to fool him twice with his fake Völundrs to make the hero lower his guard.[7] With the help of his emotion sensing eye, Jack can manipulate and trick people easily, by seeing their emotions and how they change based on his actions.

Fighting Abilities Stealth Master: When he was still an active serial killer in London, Jack was able to elude capture and always remain one step ahead, despite the whole of London's police force searching for him. While fighting Heracles in the fourth round, Jack was able to quickly set up traps and footing beforehand without being seen by the cameras or his opponent. When he was alive on Earth, Jack killed multiple people without the police ever knowing about them, causing them to never be recorded in the pages of history. He was also capable of approaching Hlökk without her even noticing his presence.

Weapons Master: Jack is shown to be proficient in many forms of weaponry, conventional or otherwise, even using the objects in his surroundings as weapons and still keep up with Heracles. The weapons he has used in the battle against the God include a giant scissor, piano wires, knives, an umbrella, a sharp fence, a door,[8] the face of Big Ben and finally, a grappling hook.

Master Knifeman: Jack's most notable weapon skill is his expert proficiency in knives, shown as he is capable of throwing knives at his enemies with great speed and accuracy.[9][10] He's also been shown hurling a giant knife like a boomerang whilst tossing smaller ones at Heracles, all the while leaping from roof to roof and back to the ground with his grappling hook.[11]

Soul Eye:[12] A unique power that he's possessed since birth, Jack's right eye possesses the ability to see people's emotions as colours. By looking into a person's "soul", Jack can discern their real intentions by even the slightest change in colour: purple for fear, red for anger, blue for pride, and yellow/orange for love. During his killing spree, Jack used his right eye to see the true colours of anyone he saw in order to kill or evade, which might be the actual reason why he was able to escape the police force. When combined with his intellect, Jack can easily manipulate people to do as he pleases, this was best shown by him forcing a Völundr with a Valkyrie by manipulating her emotions and making them "match their wavelengths". However, this ability is not without its weaknesses, since it's heavily implied that Jack cannot use his ability on himself. Another flaw is that, while he may be able to see people's actual emotions, it doesn't mean he'll truly understand them, as seen when he confused his mother's love for his father as being the love she had for him.

Menacing Aura: While not exactly to extent of the Gods and even Lu Bu, Jack does display a very intimidating presence when he wants as during his entrance into the arena on the fourth round of Ragnarok, he was able to portray an aura of killing intent in the shape of a malicious shadow of himself with a wicked smile that intimidated the human spectators. Before entering the arena and approaching Hlökk from behind, the young valkyrie expressed great fear upon sensing his presence along with wondering if he was even human at all.
