Complete Monster/Grimm (TV)

""Gangbangers and meth addicts don't make good fighters. They don't even know how to die. Where's the sport in that?" —Leo Taymor, "Last Grimm Standing"" Nick Burkhardt and company have faced many Wesen and other villains. Here are the most monstrous.


 * Billy Capra, from season 1's "Lonelyhearts", is an especially dangerous Ziegevolk, responsible for committing numerous rapes across the country. Ziegevolk naturally produce powerful pheromones that make themselves come across as more attractive and charming, especially towards the opposite sex. However, through consuming a special type of toad, Billy vastly enhances his powers, granting himself a form of Mind Control. His MO is to find vulnerable women in the nearby bar, then use his pheromones to force them to come to his bed and breakfast. Once there he imprisons them in cages in his basement, pumping the room with a powerful sedative gas to keep them docile, then rapes them over and over again until he gets bored with them. Having already kidnapped three women in Portland for a period of several months, Billy tries to capture Faith Collins but she manages to escape. Tracking Faith down, Billy suffocates her—despite his race's long standing nature of nonviolence—to keep his crimes secret. A few nights later, he tries again with another woman, Lisa. Realizing the police are onto him Billy attempts to abandon Portland, forcing Lisa to go with him.
 * Oleg Stark, from season 1's "Game Ogre", is an especially violent, hot-tempered Siegbarste, or ogre. A hitman for hire, known for mangling his victims, Stark was arrested for a series of brutal murders, and escapes jail years later to enact revenge, beating his guards into a coma before going on a Roaring Rampage of Revenge. Stark hunts down and kills the prosecuting lawyer, cutting out her tongue; cuts off the hand of the jury foreman before beating the man to death; and then goes after the judge, whose corpse the police find with Stark having stuffed his gavel down his throat. Stark tries to draw out Hank Griffin, the detective who arrested him, by setting off an explosion in a public area near his apartment. When this fails, Stark murders an old man for his car and hospitalizes Nick in an attempt to get his location. He also attacks Juliette simply for interrupting them. Brutal and cruel, even by the standards of the occasionally monstrous Wesen, Stark was an utter beast.
 * Dr. Levine, from season 1's "Organ Grinder", is the head doctor at a free clinic, known as the Folter Clinic. She is also the head of a ring of Geiers who harvest human organs in order to create products for Wesen. A vulture-like race, Geiers are infamous for this disturbing practice, but traditionally they only targeted the dead or dying, befitting vultures' status as scavengers. Levine, however, takes this brutality a step further, luring or kidnaping homeless teenagers then vivisecting and eventually murdering them. Openly taking pleasure from her grizzly acts, she forces a boy named Hanson to watch as she prepares to cut open his sister, and barely cares as her subordinates are gunned down by Portland Police, when they rescue the teens. Having murdered countless people, all in the name of profit, Levine established herself as one of the most disturbed killers amongst a race of them.
 * Leo Taymor, from season 1's "Last Grimm Standing", is a corrupt probation officer, and the leader of a gang of Löwen who resurrected the Löwen Games in Portland. While modern day Löwen have long abandoned the games, seeing them as a dark chapter of their history, Leo happily runs them for money. Using his position in overseeing parolees to find victims for his goons to kidnap, Leo then forces the captured Wesen to fight to death, preparing the combatants via Electric Torture and feeding them the bodies of the dead participants before each fight. Desiring more money, Leo broke his agreement with Sean Renard, and started kidnapping other Wesen to make the fights more interesting. He reduced one such victim, the Skalenzahne Dmitri Skontos, to nothing more than a feral beast, and caused the deaths of an elderly couple when Dmitri managed to escape. Kidnapping Dmitri's friend, the Dickfellig Brian Cooney, Leo forced him against Dmitri, and when he lost, Leo had Dmitri kill him. Knowing that a Blutbad would be a big draw, Leo had Monroe kidnapped and almost killed before Nick interrupted the fight. To save his friend, Nick himself was forced into the arena. When the Portland Police raided the games, Leo abandoned his fellow Löwen and tried to grab all his blood money, before dying at the hands of Renard's assassin. Leo was a heartless beast, driven only by greed.
 * Marnassier, from the first two episodes of season 2, was a Mauvais Dentes, a rare Saber-Tooth Tiger-like creature, and a vicious international assassin with a taste for human flesh. Responsible for at least twelve murders across Europe, he's employed by Season 2 Big Bad Prince Eric Renard to kill Nick Burkhardt and steal his key. Smuggled into Portland in a shipping container, Marnassier ensured that there were others in there with him. During the journey he slowly ate them, even leaving a taunting message written in his victim's blood, discussing how much enjoyed the taste of their flesh. Arriving in Portland, a security guard and two harbor cops investigated the blood seeping out the container, and found the victims' lacerated remains. Rather than escaping, Marnassier instead ambushed and murdered all three of them, flaying the men alive. He spent an hour eating parts of their corpses. To lure Nick into his trap, he tricked FBI Agents Durwell and Kanigher to come to him. Pretending to surrender, he overpowered both agents with his enhanced strength and speed. He then brutally murdered Durwell and forced Kanigher to call Nick to come him alone, threatening to kill her if he refused; he immediately mutilated and killed Kanigher the moment he hung up. A cold, calculating sociopath, Marnassier was truly monstrous, even among all the dangerous Wesen Nick faced.
 * Jack the Ripper himself appears in the two episodes before the season 4 finale. Infamous for the murder and mutilation of at least five women in Whitechapel, Jack actually started his reign of terror almost a hundred years earlier. In France in 1789, he murdered several Wesen women until a local Grimm killed him. A spiritual being in nature, Jack has been possessing innocent people for centuries and using them to carry out his crimes—it's heavily implied that all the cases of Jack the Ripper copycats were him—until they die, then he simply stays dormant until he can find a new host. In the modern day he turns up in Portland, latching onto the resurrected . Throughout the season he tortures the latter through hallucinations, forcing him to relieve the event of his shooting, and making his wounds bleed over and over again, almost driving him mad. Eventually he takes over and uses him to carry on his murder spree, murdering a Wesen prostitute in his signature manner. He also murders her friend when she helps the police, and then murders Henrietta for trying to help . Jack later kidnaps Wu and takes him along just so he can watch helplessly as Jack kills his next victim, and likely intends to kill Wu afterwards. When the group carry out their plan to trick Jack into thinking  is dying so he'll leave him, Jack takes over a final time and tries to strangle Rosalee. Completely Ax Crazy, solely motivated by his own sadistic entertainment and possessing an enormous body count, Jack, despite being Non-Wesen, stands out as one of the worst enemies Nick ever faced.
 * Conrad Bonaparte, the Big Bad of season 5 and a very powerful Zauberbiest, was the co-founder and leader of the Black Claw terrorist organization, which think of the Wesen as a Master Race. Already responsible for many of Black Claw's attacks around the world, Bonaparte organized their attempts to subjugate Portland. Setting up local political candidate Andrew Dixon, then having him assassinated so Sean Renard could take his place, Black Claw spread destruction and murder throughout the city, including inspiring the temporary resurrection of a barbaric ritual, and launching an attack upon Wesen-run businesses that didn't join them. Arriving to personally oversee events Conrad proceeded to: set up several of his loyal agents to die to provide a distraction; forced Adalind Schade to join them by threating her children; was both directly and indirectly responsible for many deaths, including Monroe's Uncle Felix; attacked and destroyed the local Hadrian's Wall base; and painfully cursed Adalind when she proved uncooperative. Conrad also used his powers to slowly, brutally murder Meisner, forcing Renard to Mercy Kill him, an act he took great pleasure from; and to torture Nick Burkhardt by inducing both extreme physical pain and nightmarish hallucinations involving Nick's son. After his attempt to secure a book detailing the lineage of all Grimms failed, Bonaparte fatally wounded Eve, tortured Nick's address out of Adalind and ordered an all-out assault upon Nick and his allies. Following Nick destroying his entire Army, Conrad displayed no regard for his fallen followers, only acknowledging that he underestimated Nick before trying to personally murder him. Underneath a calm and seemingly-friendly exterior, Bonaparte was a man of no morals or standards, driven by an unshakable belief in Wesen supremacy and complete disregard for even his most loyal followers.
 * Zerstörer, the Big Bad of Season 6 and of the entire series, is an ancient devil-like creature who millennia ago stole a "staff with the power of the gods" to bring about Hell on Earth. Defeated by the ancient Grimms, he was imprisoned in Hell, where animalistic Wesen rule and humans are "walking meat." Ruling over the chaos, Zerstörer waited until 2017 when he could escape. Needing a Grimm to break the spell, Zerstörer targeted Eve, taking control of her body to inscribe his symbols with her own blood, then stalking and almost strangling her, all so she would lure Nick into his realm. Once free, Zerstörer's first act was to skewer a man for just being in there, and then murdered another person - by causing his eyes to explode — for his clothes. Seeking the Shaphant, his destined child bride—and Renard and Adalind's preteen daughter Diana—and the final piece of his staff, Zerstörer went on a murder spree, climaxing with him slaughtering every single person within the precinct, including Hank and Wu. He then targeted everyone who Nick cares about: forcing Eve to slowly stab herself to death; stabbing Renard through the heart when he tries to protect Diana; using Nick's ax to kill Adalind; turning his staff into a serpent to poison Monroe and Rosalee; and finally strangling Trubel; all to force Nick into a deal to give him the staff's final piece and thus the power to merge the world with hell, creating eternal chaos for him to rule over. Cruel, cunning, and incredibly powerful, Zerstörer was an opponent like nothing else Nick had ever encountered.
