[[quoteright:320:https://static.tvtropes.org/pmwiki/pub/images/ced15a6959930779decdf513f44cbe48.jpg]]
!!!'''First Appearance:''' ''Marvel Spotlight'' #2 (1972)

Victim of an ancient family curse, Jack Russell struggled for years with his bestial alter-ego. But over time has conquered his inner demons. Now he fights the dark forces that plague our world. He is an enforcer of justice, an avenger of shadows, and a Werewolf By Night.
----
* SeventiesHair: Jack (logically) sports it in his appearances during the 70s, but sometimes goes back to it in later years, notably in ''Witches'' #1 (2004) and ''X-Factor'' #242 (2012).
* NinetiesAntiHero: Jack developed shades of this after ''Comicbook/MarvelComicsPresents'' #54-59 in 1990. He sported longer hair, rode a motorcycle, [[NoShirtLongJacket wore a leather jacket with nothing under it]], and suddenly started using colloquialisms. His attitude changed accordingly, from a guy suffering under his curse to reveling in it. After volume 2 he kept the hair and the motorcycle, but MediaNotes/TheDarkAgeOfComicBooks was shed.
* TheAlcoholic: In ''[=WbN=]'' volume 2 Jack drowns his sorrows about the curse in large quantities of booze. He even drinks while ''driving a car''.
* {{Angst}}: After [[spoiler:nearly killing Buck]] Jack’s mood progressively edges towards suicidal. Things start to look up again, until he hits absolute rock-bottom in ''[=WbN=]'' volume 2.
* BigBrotherInstinct: Whether he's man or beast he's very protective towards his little sister.
* BreakTheCutie: In the time between volumes 1 and 2 the curse breaks Jack beyond recognition.
* CharacterDevelopment: Jack has been around since 1972 and has changed quite dramatically over the years. A wide-eyed teenager dragged into all kinds of supernatural mayhem against his will (1970s) → a leather-clad motorcycle riding AntiHero living life to the fullest (late 80s-early 90s) → a downtrodden alcoholic doing everything in his power not to have to face reality (late 90s) → a suicidal hotheaded {{Jerkass}} looking for a fight (late 2000s) → a pleasant guy looking after monsters when the rest of the world would rather kill them (early 2010s).
* DeadpanSnarker: Jack is one, usually in combination with SelfDeprecation.
* DependingOnTheArtist: Jack's werewolf form varies depending on whose drawing him, most artists have him resemble Lon Chaney Jr, while some give him a more wolf like head. When he showed up in X-Factor he was given a tail.
* TheDrifter: Though his home base is UsefulNotes/LosAngeles, Jack never stays in one place for very long.
* EnemyWithin: As mentioned in ''ComicBook/XFactor'' #224, human Jack vs werewolf Jack is a constant struggle.
* FakeDefector: His stint with the Night Shift is a case of this, especially considering one of his old foes, Tatterdemalion, was also on the team.
* GoshDangItToHeck: Jack mostly uses "stinking" to express displeasure. Possibly justified by his heightened senses, particularly smell, and his human mores remaining in effect. "Stinking" could well become quite the pejorative term if you really know how foul something smells.
* IAmAMonster: It varies, but Jack occasionally sees himself as this. Other times he is more accepting of himself, crossing over into IAmWhatIAm; often he fluctuates between the two.
* IJustWantToBeNormal: Finding a cure for his condition is what drives Jack in most of his adventures. Even though in ''Tomb of Terror'' #1 he admits he sees his werewolf side as his true self and loves the freedom it comes with, he still wants it to end.
* InformedAbility: Many of Jack's powers and abilities as described in the Official Marvel Handbooks are never shown in-story. For example, it's said Jack is a practiced magic user who often casts spells, yet he is only shown doing so one single time (in ''Comicbook/MarvelComicsPresents'' #54).
* LimitedWardrobe: While the shirt or jacket he wears (''[[WalkingShirtlessScene if]]'' [[ShirtlessScene he wears one]]) may differ, it seems Jack has stocked his wardrobe to the brink with green pants.
* MagicPants: Jack manages to ruin his clothes with alarming regularity, but in the majority of cases his pants stay firmly on.
* MeaningfulName: A Jack Russell Terrier is a breed of dog.
* TheNicknamer: Especially Morbius is on the receiving end of this in later years: Morb, Mikey-boy, M., Dracubilly... Ironically, in ''ComicBook/{{Morbius}}'' v2, Morbius responds to someone else calling him "Mike" with "I prefer Michael".
* OurWerewolvesAreDifferent: Jack inherited the curse from his father, and is [[InvoluntaryShapeshifting forced]] to change [[WeirdMoon during the three nights a month the moon is full]]. His werewolf self grows progressively more violent over time, and the pain that accompanies the transformation increases with each full moon. He eventually gains [[VoluntaryShapeshifting some control over the change]] with the help of [[spoiler:The Three Who Are All]], enabling him to transform outside the full moon as well. For a while this control extends to no longer having to change at all during the full moon and retaining his mind at all times, but those days don’t last.\\
\\
Initially the werewolf looks like a typical wolfman à la Lon Chaney Jr. Starting with ''Moon Knight'' #29 (1982), his appearance becomes more wolfish, still standing on two legs but with a fully lupine head. This change is explained as his werewolf self regressing ever further after an experiment to gain more control went badly.
* PainfulTransformation: Until he is helped [[spoiler:by The Three Who Are All]], each transformation is more painful than the last. And it’s not just on a physical level: Jack describes part of the transformation as if ''his soul is being ripped apart''. After he gains control of, the changes become more bearable. But then the full moons come with the added side-effect of [[spoiler:glimpsing hell]].
* PunnyName: A jack russell is a kind of terrier. But Jack is a nickname for Jacob and Russell is the Americanized equivalent of his ancestorial name, Rusoff, so it’s not like his parents intentionally named him after a dog.
* RedheadInGreen: The red-furred werewolf runs around in torn-up green pants a lot.
* ResistTheBeast: Jack often tries this while subject to [[InvoluntaryShapeshifting involuntary transformations]] brought on by the full moon; sometimes it works, usually it doesn't.
* SelfDeprecation: A habit of Jack’s. Upon changing into a werewolf through the sheer force of will for the first time: “It might’ve been the ugliest one on record, but it was still a miracle.”
* SlasherSmile: Jack is quite capable of them, especially in ''[=WbN=]'' volume 2. Even more so if he couples it with a couple of razor-sharp teeth.
* StagesOfMonsterGrief: Jack goes from denial to anger to acceptance to seeing his condition as a blessing to self-destruction and back again. In ''Marvel Zombies 4'' #3 he claims he’s gone through all five stages of grief and has finally reached acceptance. Teammate Morbius thinks he simply no longer cares whether he lives or dies.
* WalkingShirtlessScene: Due to his transformations, Jack spends half of the time shirtless.
* WalkingTheEarth: Jack mostly rides his motorbike across North America but ends up in Italy on at least one occasion.
* WolfMan: How wolf-like Jack's werewolf form looks fluctuates, but he always retains somewhat human proportions, and walks on two legs. Other werewolves, even those subject to the same curse such as Jack's niece Nina, may look much more wolf-like.

[[folder:Dr. Kalbfleisch]]

!!! '''First Appearance:''' ''Dead of Night Featuring: Werewolf by Night'' #1

The leader of the Babylon Group, and the BigBad of the non-canonical Creator/MarvelMax title ''Dead of Night Featuring: Werewolf by Night.'' A scientist who captures and studies "inter-species" people, like the werewolf Jack Russell and his sister, Jenny.

----

* CovertGroup: As Kalbfleisch explains it, the Babylon Group is affiliated with the United States government (which provides it with specimens, like Jack and Jenny) but not actually apart of it, instead acting as a kind of secret R&D division for pharmaceutical concerns all over the Earth.
* FatalFlaw: His shortsightedness, at least when it came to the Russells. His leniency and simple carelessness due to desperation and scientific curiosity basically caused one big line of DisasterDominoes.
* GildedCage: His offer to Jack and Jack's daughter, and presumably any other animal people who could be reasoned with, as he mentions that some of them are with the Babylon Group simply because they "have nowhere else to go."
* GodzillaThreshold: He lets the Babylon Group's two most dangerous patients, a Frankenstein's Monster-like being and a vampire-like man, out of their rooms to try and stop Jack, because they were only ones who stood any chance at all of slowing down "that unholy thing" (Jack).
* GreyAndGrayMorality: His methods are extreme, but have led to revolutionary medical breakthroughs, and while Jack is the protagonist, his werewolf alter-ego is a monster who has slaughtered a lot of innocent people all over the country, and a few of the Babylon Group's patient-prisoners included obviously very dangerous superhumans like a psychotic who responded to any noise with gruesome violence, a man who EatsBabies, and Jack's sister, Jenny, who, despite being portrayed sympathetically, still murdered literally everyone in her hometown (from babies to the elderly, many of whom she "sampled" while they were still alive) when her powers manifested for the first time in 1983.
* IndyPloy: Jack having a fiancée and Jenny killing her when she was let loose to find Jack were unexpected developments, but Kalbfleisch decided to roll with it and make the best of a bad situation by having his agents scour the city for Jack, follow him, and then just call 911 as soon as Jack got home, with the expectation being that Jack would be too distraught over his lover's death to resist being arrested, at which point the Babylon Group could just swoop in and take custody of Jack, with Kalbfleisch noting, "No one wonders about a murderer once he disappears into the legal system." This did not work out, as Jack did resist arrest and flee the scene, attracting unwanted attention and forcing Kalbfleisch's agents to resort to finding and dismantling Jack's saferoom to force Jack to turn himself over to the Babylon Group.
* MortonsFork: One of his agents, acting of her own accord, gave Jack the choice of turning himself in peacefully, but also dismantled Jack's saferoom, so Jack would have no choice but to turn himself in or risk people being hurt or killed by the Werewolf.
* MyGreatestFailure: He appears to consider Jack this, lamenting that not stepping in sooner led to the Werewolf killing Jack's adoptive parents and Jack disappearing, with the Babylon Group wasting years searching for him as he uncontrollably killed people all over the US before finally gaining the means to settle down and build a saferoom in Philadelphia.
* PetTheDog: He could have just taken baby Jack after he and Jenny were handed over to him by the government after Jenny's massacre of their hometown, but the chances of Jack actually being a werewolf (which are mainly female) were so low that Kalbfleisch instead decided to just give Jack to loving parents, the Russoffs, with no strings attached other than having the Russoffs bring Jack in every month or so to donate blood (which was used to keep Jenny alive after her battle with the authorities) and partake in unexplained tests; it was only when Jack started showing definitive signs of lycanthropy as a teenager that Kalbfleisch decided that Jack should be taken in, as allowing him to continue living normally would be too risky, a decision which is hard to argue with given that Jack did end-up turning into the Werewolf and slaughtering the Russoffs (among many others who somehow pissed it off) due to a misunderstanding[[note]](it thought that they were going to kill it because it had overheard that the next visit to the Babylon Group would "[[NoLongerWithUs be the last]]")[[/note]] when the Russoffs decided not to give Jack back to the Babylon Group.
--> '''Kalbfleisch:''' When we found your parents, we were heartbroken. All of those years watching you grow into a young man, unaware of your capabilities, only to have them manifest like this... well, we could have helped you.
** Later:
--> '''Jack:''' You lied to me, Doc. All of you. You should have told me the truth about--\\
'''Kalbfleisch:''' You're right. We should have. And we're going to make up for it now.
* PlayingWithSyringes: He keeps "inter-species" people in either medically-induced comas (though he claims that most of them have little in the way of consciousness to speak of anyway due to their warped physiologies, which is why so many of them die in the womb) or cells, and experiments on them ForScience.
* SpannerInTheWorks:
** He did not expect the Russoffs to become as attached to Jack as they did, so when he informed them that he would have to take Jack back once Jack started showing definitive symptoms of lycanthropy, the Russoffs tried to run away with Jack, which gave the Werewolf the time and the stressor (it thought that the Russoffs were going to kill it) that it needed to manifest for the first time and, unfortunately, kill the Russoffs.
** He let Jenny loose in a desperate attempt to find Jack, but did not expect her to instead go after Jack's pregnant fiancée, Cassandra (since he had no way of knowing that she even existed). His team subdued the frenzied Jenny, but failed to save Cassandra, and only just barely managed to save her and Jack's daughter.
* WellIntentionedExtremist: He keeps "inter-species" people either locked up or catatonic, but the Babylon Group's studying of them has led to revolutions like cures for Polio and Diphtheria, and he believes that continued research will help them achieve "so much more."
